WHAT IS THE GOES-R SERIES?
NOAA's latest generation of geostationary weather satellites
The Geostationary Operational Environmental Satellite (GOES) – R Series is the
nation’s most advanced fleet of geostationary weather satellites. The GOES-R
Series significantly improves the detection and observation of environmental
phenomena that directly affect public safety, protection of property and our
nation’s economic health and prosperity.
The satellites provide advanced imaging with increased spatial resolution and
faster coverage for more accurate forecasts, real-time mapping of lightning
activity, and improved monitoring of solar activity and space weather.
The GOES-R Series is a four-satellite program (GOES-R/S/T/U) that will extend
the availability of the operational GOES satellite system through 2036.
WHY THE GOES-R SERIES?
* Improved hurricane track and intensity forecasts
* Increased thunderstorm and tornado warning lead time
* Earlier warning of ground lightning strike hazards
* Better detection of heavy rainfall and flash flooding risks
* Improved transportation safety and aviation route planning
* Improved detection of low cloud/fog
* Improved air quality warnings and alerts
* Better fire detection and intensity estimation
* Improved solar flare warnings for communications and navigation disruptions
* More accurate monitoring of energetic particles responsible for radiation
hazards to humans and spacecraft
* Better monitoring of space weather to improve geomagnetic storm forecasting
BEYOND ENVIRONMENTAL SENSING
Remote environmental sensing is only part of the GOES-R Series mission. The
satellites also provide unique capabilities to relay data directly to users to
meet critical needs
DATA COLLECTION SYSTEM (DCS)
DCS is a satellite relay system used to collect information from Earth-based
data collection platforms that transmit in-situ environmental sensor data from
more than 20,000 platforms across the hemisphere.
GOES REBROADCAST (GRB)
GOES Rebroadcast provides the primary relay of full resolution, calibrated,
near-real-time direct broadcast space relay of Level 1b data from each
instrument and Level 2 data from the Geostationary Lightning Mapper (GLM). GRB
replaces the GOES VARiable (GVAR) service
HIGH RATE INFORMATION TRANSMISSION/EMERGENCY MANAGERS WEATHER INFORMATION
NETWORK (HRIT/EMWIN)
The Emergency Managers Weather Information Network (EMWIN) is a direct service
that provides users with weather forecasts, warnings, graphics and other
information directly from the National Weather Service (NWS) in near real-time.
The HRIT service is a new high data rate (400 Kpbs) version of the previous LRIT
(Low Rate Information Transmission), broadcasting GOES-R Series satellite
imagery and selected products to remotely-located user terminals.
SEARCH AND RESCUE SATELLITE AIDED TRACKING (SARSAT)
The SARSAT system detects and locates mariners, aviators and other recreational
users in distress. The GOES-R Series continues the legacy function of the SARSAT
system on board NOAA’s GOES satellites. This system uses a network of satellites
to quickly detect and locate signals from emergency beacons onboard aircraft,
vessels and from handheld personal locator beacons. The GOES-R Series SARSAT
transponder operates with a lower uplink power than the current system (32 bBm),
enabling GOES-R Series satellites to detect weaker beacon signals.

constellation.

ABOUT THE VIEWS
Environmental satellites provide data in several different formats. The most
commonly used channels on weather satellites are the visible, infrared, and
water vapor.
Visible satellite images, which look like black and white photographs, are
derived from the satellite’s signals. Clouds usually appear white, while land
and water surfaces appear in shades of gray or black. The visible channel
reflects solar radiation. Clouds, the Earth's atmosphere, and the Earth's
surface all absorb and reflect incoming solar radiation. Since visible imagery
is produced by reflected sunlight (radiation), it is only available during
daylight.
In the infrared (IR) channel, the satellite senses energy as heat. The Earth’s
surface absorbs about half of the incoming solar energy. Clouds and the
atmosphere absorb a much smaller amount. The Earth’s surface, clouds, and the
atmosphere then re-emit part of this absorbed solar energy as heat. The infrared
channel senses this re-emitted radiation. Infrared imagery is useful for
determining cloud features both at day and night.
Water vapor imagery is used to analyze the presence and movement of water vapor
moisture in the upper and middle levels of the atmosphere. The wavelength
spectrum used to detect water vapor is in the 6.7 to 7.3 micrometer wavelength
range. The darker regions in water vapor imagery are areas where very little
water vapor exists in the middle and upper troposphere, and the lighter regions
are very moist. Water vapor imagery is a very valuable tool for weather analysis
and prediction because water vapor imagery shows moisture in the atmosphere, not
just cloud patterns. This allows meteorologists to observe large-scale
circulation patterns even when clouds are not present.
NOAA WEATHER CONSTELLATION
The National Oceanic and Atmospheric Administration (NOAA) maintains two primary
constellations of environmental satellites: geostationary and polar-orbiting.
These satellites are part of NOAA's integrated observing system, which includes
satellites, radar, surface automated weather stations, weather balloons,
sounders, buoys, instrumented aircraft and other sensors, along with the data
management infrastructure needed for this system.
GEOSTATIONARY SATELLITES
Geostationary satellites orbit 35,800 km (22,300 miles) above Earth's equator at
speeds equal to Earth's rotation, which means they maintain their positions and
provide continuous coverage. Information from geostationary satellites is used
for short-term (1 day) weather forecasting and severe storm warning and
tracking.
POLAR-ORBITING SATELLITES
Polar-orbiting satellites make regular orbits around the Earth’s poles from
about 833 km (517 miles) above the Earth’s surface. The Earth constantly rotates
counterclockwise underneath the path of the satellite, making for a different
view with each orbit. Information from polar-orbiting satellites is used for
mid-range (3-7 day) forecasts and advanced warnings of severe weather.
GOES VIEW OF EARTH
GOES satellites continually view the continental United States, Pacific and
Atlantic Oceans, Central and South America, and Southern Canada. To fully cover
Alaska, Hawaii, the entire continental United States and the Pacific and
Atlantic Oceans (for tropical storms), NOAA operates two GOES satellites
simultaneously: GOES East and GOES West. GOES East is located at 75.2° W and
provides most of the U.S. weather information. GOES West is located at 137.2°W
over the Pacific Ocean. In addition to two operational satellites, NOAA also
maintains an on-orbit spare.
CONSTANT IMPROVEMENT
Since 1975, GOES have provided continuous imagery and data on atmospheric
conditions and solar activity (space weather). They have even aided in search
and rescue of people in distress. GOES data products have led to more accurate
and timely weather forecasts and better understanding of long-term climate
conditions. NASA builds and launches the satellites and NOAA operates them.
GOES-R SERIES LAUNCHES
GOES-R launched on November 19, 2016, and was followed by GOES-S on March 1,
2018. GOES-T launched on March 1, 2022, and GOES-U is planned for launch in
2024.

LAUNCH AND ORBIT
Description | More Details | Video
GOES-T, the third satellite in the GOES-R Series, launched on March 1, 2022.
GOES-T lifted off from Space Launch Complex 41 at Cape Canaveral Space Force
Station, Florida, aboard an Atlas V 541 rocket. GOES-T reached geostationary
orbit on March 14, 2022, and was renamed GOES-18. GOES-18 replaced GOES-17 as
the operational GOES West satellite at 137.0 degrees west longitude on January
4, 2023.
GOES-S launched on March 1, 2018 and was renamed GOES-17 when it reached
geostationary orbit on March 12, 2018. GOES-17 joined its sister satellite,
GOES-16, in orbit. The first satellite in the series, GOES-R, launched on
November 19, 2016, and became GOES-16 when it reached geostationary orbit.
GOES-16 replaced GOES-13 as NOAA’s operational GOES East satellite at 75.2
degrees west longitude on December 18, 2017. GOES-17 served as GOES West from
February 12, 2019 until it was replaced by GOES-18 on January 4, 2023. GOES-17
is now the on-orbit standby for the operational constellation.
GOES-U is planned for launch no earlier than May 2024.
GOES satellites are placed into a geosynchronous orbit that keeps them over a
specific location on the earth. By maintaining a position hovering over a fixed
point on Earth's surface, GOES are able to constantly monitor atmospheric
conditions in a particular portion of the Earth's atmosphere. Note that
non-geosynchronous orbits (for example polar orbits) move over an ever-rotating
earth underneath them, therefore seeing a constantly changing view, which has
advantages for other types of missions.

MARCH
* MARCH 7, 2024: EARTH FROM ORBIT: FIRES RAGE ACROSS TEXAS PANHANDLE
Since late February, NOAA satellites have been tracking wildfires that spread
through the Texas Panhandle. The largest wildfire in the state’s history
broke out on Feb. 26 and quickly spread, fueled by dry, windy conditions. By
Mar. 4, the blaze, known as the Smokehouse Creek fire, had become one of the
largest fires in U.S. history. GOES-16 (GOES East) observed these fires in
near-real time. This geostationary satellite keeps constant watch over the
same geographic area over time, and helps to locate fires, detect changes in
a fire’s behavior, and predict its direction. By combining data from multiple
channels on its Advanced Baseline Imager (ABI) instrument, both a fire’s hot
spot and associated smoke plume can be visualized.
* MARCH 1, 2024: CELEBRATING WOMEN IN GEO
In honor of Women’s History Month, a new web feature turns the spotlight on
women in NOAA’s Office of Geostationary Earth Orbit Observations. Celebrating
Women in GEO tells the stories of women who are driving innovation and who
have been instrumental within its geostationary satellite programs. These
remarkable individuals exemplify the spirit of innovation, dedication, and
leadership, and are helping to shape the future of how we monitor our
constantly changing world. Ultimately, the work these women do helps
safeguard lives, protect communities, and preserve our planet’s vital natural
resources. Their contributions are also inspiring future generations to
pursue careers in science, technology, engineering, and mathematics (STEM).
* MARCH 1, 2024: EARTH FROM ORBIT: GREAT LAKES ICE REACHES HISTORIC LOW
As we leave meteorological winter behind, NOAA satellites have been
monitoring the extent of ice coverage in the Great Lakes. The Great Lakes
typically see peak ice coverage in late February to early March. Ice plays an
important role in the ecosystems, economy, and coastal resilience of the
Great Lakes. In 2024, ice coverage reached a historic low. A number of
factors have contributed to the historic low this year, such as a strong El
Niño and well above-average temperatures this winter. NOAA satellites have
observed little ice on the Great Lakes this year.
FEBRUARY
* FEBRUARY 27, 2024: LAUNCH OF GOES-U SATELLITE DELAYED
NASA and SpaceX are now targeting no earlier than May 2024 for the launch of
NOAA's GOES-U satellite. The new date allows for additional testing and
preparation of a new Falcon Heavy center core booster after a liquid oxygen
leak was discovered during routine new booster testing. GOES-U is the fourth
and final satellite in the GOES-R Series of advanced geostationary
satellites.
* FEBRUARY 8, 2024: EARTH FROM ORBIT: GOES-U ARRIVES AT KENNEDY SPACE CENTER
The latest video in the Earth from Orbit series highlights GOES-U’s arrival
at Kennedy Space Center last month. After being packed in a high-tech
shipping container that acts as a mobile clean room, GOES-U caught a ride
aboard a C-5 Super Galaxy aircraft from Buckley Space Force Base in Colorado
to NASA’s Kennedy Space Center in Florida. After landing, the satellite was
taken to Astrotech Space Operations, where it was removed from its shipping
container, inspected, and placed onto a test stand. GOES-U will now undergo
final preparations for a spring 2024 launch from Kennedy Space Center, where
it will launch aboard a SpaceX Falcon Heavy rocket.
JANUARY
* JANUARY 23, 2024: GOES-U ARRIVES AT KENNEDY SPACE CENTER
The satellite is in Florida to begin final preparations for its upcoming
launch.
NOAA’s GOES-U, the fourth and final satellite in the GOES-R Series of
advanced weather-observing and environmental monitoring satellites, arrived
at NASA’s Kennedy Space Center in Florida on Jan. 23, 2024, to begin final
preparations for its upcoming launch. Shipping a satellite is no small feat.
GOES-U is the size of a small school bus and weighs over 6,000 pounds! The
spacecraft team at Lockheed Martin in Littleton, Colorado, where GOES-U was
built, packed the satellite in a high-tech shipping container that protected
its sensitive instruments and acted as a mobile clean room during transport.
GOES-U was then driven to Buckley Space Force Base in Aurora, Colorado, and
loaded on the C-5M Super Galaxy cargo transport that carried it to Florida.
GOES-U safely landed at the NASA Launch and Landing Facility airstrip at
Kennedy Space Center and was transported to the Astrotech Space Operations
spacecraft processing facility in nearby Titusville, where it will go through
a series of electrical tests to confirm it is working properly and mechanical
configurations to prepare it for launch. GOES-U is scheduled to launch no
earlier than April 30, 2024.
* JANUARY 17, 2024: GOES-U: ROAD TO LAUNCH
NOAA’s GOES-U, the fourth and final satellite in the Geostationary
Operational Environmental Satellites (GOES) – R Series, the Western
Hemisphere’s most advanced weather-observing and environmental monitoring
system, is entering the final stage of preparations before liftoff. NASA and
SpaceX are targeting no earlier than April 30 for the launch of GOES-U on a
Falcon Heavy rocket. The GOES-U team has spent years building the instruments
and spacecraft, integrating all the satellite’s components, and conducting
rigorous testing to ensure it can withstand the harsh launch conditions and
successfully take up residence 22,236 miles above Earth. Before that happens,
the spacecraft must complete several final milestones. Learn more about
GOES-U’s road to launch.
* JANUARY 11, 2024: FOURTH QUARTER 2023 GOES-R/GEOXO NEWSLETTER
The GOES-R Program and L3Harris celebrated the GOES-R ground system
development contract close-out
The GOES-R/GeoXO quarterly newsletter for October – December 2023 is now
available. Happy New Year! It’s a very exciting time for the GEO Program! We
are gearing up to launch the last of the GOES-R Series satellites. GOES-U
will soon ship to Kennedy Space Center and begin final preparations for its
planned launch in April. GeoXO also had a successful quarter. The final
development RFP, for the ACX instrument, was released in October. Evaluation
boards are busy reviewing proposals for the spacecraft and the OCX, LMX, and
ACX instruments. GOES-16 and GOES-18 continue to provide critical data to
keep us informed of and safe from severe weather and environmental hazards.
The program is looking forward to more GEO successes in 2024!
* JANUARY 4, 2024: EARTH FROM ORBIT: 2023 SATELLITE IMAGERY: A YEAR IN REVIEW
NOAA satellites see our planet from a unique and captivating perspective.
Every year, they capture the beauty and wrath of Mother Nature unfolding
beneath them—devastating hurricanes, raging wildfires, erupting volcanoes—as
well as the changing seasons, ocean color, nighttime lights, and more. The
view of NOAA satellites isn’t just limited to Earth; they also capture images
of our moon and the sun as we navigate our cosmic journey. As we head into
the new year, take a look back at some satellite imagery highlights from
2023.
DECEMBER
* DECEMBER 8, 2023: EARTH FROM ORBIT: ATMOSPHERIC RIVERS DRENCH THE PACIFIC
NORTHWEST
NOAA satellites monitored a series of storms from an atmospheric river that
impacted the Pacific Northwest in early December 2023. On Dec. 4, the storms
brought record-breaking rainfall, flooding, and significant snowfall to some
areas. Atmospheric rivers are long, narrow belts of moisture that move
through the atmosphere. GOES-18 (GOES West) tracked the band of moisture as
it moved over the Pacific Ocean and into the Pacific Northwest in near
real-time. NOAA satellites provide critical data for forecasting atmospheric
weather river events and monitoring the weather conditions they bring.
NOVEMBER
* NOVEMBER 28, 2023: EARTH FROM ORBIT: 2023 ATLANTIC HURRICANE SEASON WRAPS UP
NOAA satellites constantly monitor the ocean for tropical activity. As the
2023 Atlantic hurricane season comes to a close, we’re looking back at this
above-normal season. This season was very active in terms of the number of
named storms, ranking fourth for most named storms in a year. The Atlantic
basin saw 20 named storms in 2023. Seven of these were hurricanes and three
intensified to major hurricanes (Category 3 or higher on the Saffir-Simpson
Hurricane Wind Scale). An average season has 14 named storms, seven
hurricanes and three major hurricanes. Although the season runs from June 1
to Nov. 30, tropical and subtropical cyclone formation can occur at any time
and NOAA satellites will be keeping watch.
* NOVEMBER 02, 2023: EARTH FROM ORBIT: HURRICANE OTIS CAUSES CATASTROPHIC
DAMAGE
On Oct. 25, 2023, NOAA satellites monitored Hurricane Otis as it hit Mexico’s
southern Pacific coast near Acapulco as a Category 5 storm. Otis was the
strongest hurricane in the Eastern Pacific to make landfall in the satellite
era. The hurricane brought storm surge, flooding, mudslides, and strong winds
to the coast and caused widespread damage and fatalities in the region. GOES
East and GOES West watched in near real-time as Otis rapidly intensified from
a tropical storm to a Category 5 hurricane within a 24-hour period. The
Geostationary Lightning Mapper (GLM) measured lightning within the eyewall
while it was rapidly intensifying. Infrared imagery showed the structure of
the storm as it developed and intensified before making landfall.
OCTOBER
* OCTOBER 19, 2023: EARTH FROM ORBIT: NOAA SATELLITES VIEW ANNULAR ECLIPSE
On Oct. 14, NOAA satellites caught an annular eclipse as it traversed parts
of North, Central, and South America. A solar eclipse occurs when the moon
crosses between the Earth and the sun, and casts a shadow. An annular solar
eclipse occurs when the moon is farther away from Earth when they pass each
other. In this event, the moon does not completely block out the sun and
causes a ring of fire to appear. NOAA’s GOES satellites viewed the moon’s
shadow as it moved across the Earth in near real-time. The Solar Ultraviolet
Imager (SUVI) onboard GOES East also captured the eclipse. SUVI observed the
moon crossing in front of the sun. As the April 8, 2024 total solar eclipse
approaches, NOAA satellites will be waiting to capture the event.
* OCTOBER 12, 2023: THIRD QUARTER 2023 GOES-R/GEOXO NEWSLETTER

The GOES-R/GeoXO quarterly newsletter for July – September 2023 is now
available. The GOES-R and GeoXO programs accomplished a lot this quarter.
GOES-U completed environmental testing and is preparing for its Pre-Shipment
Review at the end of October. The ground, flight, and mission operations
teams are busy conducting rehearsals and readiness exercises to prepare for
the April 2024 launch. We awarded the second GeoXO development contract to
build the Sounder and released three development RFPs this quarter – for the
Lightning Mapper and Ocean Color instruments and the spacecraft. Also, the
GeoXO Imager had a successful System Requirements Review/System Definition
Review and is proceeding to the preliminary design phase. And we welcomed our
new deputy program director, Brian Hall.
* OCTOBER 06, 2023: EARTH FROM ORBIT: HEAVY RAINS CAUSE FLOODING IN NEW YORK
CITY
The remnants of Tropical Storm Ophelia over the Atlantic Ocean combined with
a mid-latitude system arriving from the west unleashed more than eight inches
of rain in parts of the New York metropolitan area on Sept. 28-29, 2023. NOAA
satellites monitored conditions as torrential rain led to flood water
coursing through streets and into basements, schools, subways, and vehicles
throughout the nation’s most populous city. Data from GOES and JPSS were also
used to produce flood maps that helped to determine the impact of the storm –
where flooding was happening, what the extent was, how long it would last,
and what damage occurred.
SEPTEMBER
* SEPTEMBER 14, 2023: NOAA’S GOES-U COMPLETES ENVIRONMENTAL TESTING
GOES-U, the fourth and final satellite in NOAA’s GOES-R Series of advanced
geostationary satellites, recently completed rigorous testing to ensure it
can withstand the harsh conditions of launch and maintain functionality in
orbit 22,236 miles above Earth. The testing process spanned nearly a year and
was conducted by Lockheed Martin and SpaceX personnel at the Lockheed Martin
facility in Littleton, Colorado, where the satellite was built. GOES-U is on
track for an April 2024 launch from Cape Canaveral Space Force Station in
Florida aboard a Falcon Heavy launch vehicle.
AUGUST
* AUGUST 24, 2023: EARTH FROM ORBIT: 2023 HURRICANE ACTIVITY RAMPS UP
NOAA satellites have been monitoring increased tropical activity in the
Atlantic and Pacific, with five named storms developing in the last week. As
NOAA satellites were monitoring Tropical Storm Hilary as it brought
torrential rainfall, flooding, and mudslides to Southern California, a series
of storms were forming in the Atlantic. Within the span of 18 hours, three
tropical storms formed—Emily, Franklin, and Gert. While Emily and Gert were
relatively short-lived and dissipated over the ocean, Franklin, which formed
east of the Leeward Islands, made landfall in the Dominican Republic on
August 23, bringing heavy rains to Hispaniola. By August 22, another tropical
storm, Harold, formed in the western Gulf of Mexico, making it the fourth
Atlantic named storm to form within 39 hours. Harold made landfall on San
Padre Island, Texas on August 22, and was the first Atlantic storm this
season to do so in the U.S. August 20 marked the beginning of what is
typically the most active portion of the Atlantic hurricane season.
Historically, more than 85 percent of all major (Category 3, 4, and 5)
Atlantic hurricanes form after this date. As the Atlantic and Pacific
hurricane seasons continue, NOAA satellites remain our watchful eyes in the
sky, providing critical information for hurricane forecasting, tracking, and
intensity estimation.
* AUGUST 11, 2023: NOAA RELEASES UPDATED 2023 ATLANTIC HURRICANE SEASON OUTLOOK
On Aug. 10, NOAA updated its 2023 Atlantic hurricane season outlook. NOAA is
now expecting above normal activity in the Atlantic. El Niño and record sea
surface temperatures are contributing factors. The update includes an
increase in named storms to 14-21, with 6-11 developing into hurricanes. Of
those, 2-5 are anticipated to be major hurricanes – Category 3 or higher. The
2023 Atlantic hurricane season started early on Jan. 16 with an unnamed
subtropical storm that formed southeast of Nantucket, Massachusetts. Since
the first official day of the 2023 Atlantic hurricane season, June 1, there
have been four named storms: Arlene, Bret, Cindy and Don. Out of the four,
only one strengthened into a hurricane. Hurricane Don developed into a
Category 1 hurricane on July 22 in the northern Atlantic. NOAA satellites
provide critical data for hurricane forecasting as well as advanced
technology to track the storms—their location, movement, and intensity. The
satellites provide a detailed look at storm properties, specific features of
a hurricane’s eye, wind estimates, and lightning activity. As peak hurricane
season approaches, NOAA satellites will be watching for the development of
these storms.
JULY
* JULY 28, 2023: EARTH FROM ORBIT: FIRES BLAZE ACROSS WESTERN U.S.
As record-breaking heat continues to scorch parts of the southwestern U.S.
and Mexico, NOAA satellites are monitoring fires in the western U.S., which
are sending plumes of smoke into the atmosphere. As of July 26, 2023, a total
of 39 fires have burned 201,637 acres in nine states, including Arizona, New
Mexico, Oregon, Idaho, Colorado, California, Texas, Montana, and Washington.
NOAA satellites are tracking the fires and their impact. GOES-18 (GOES West)
identified hot spots as they ignited and monitored the movement of smoke from
the fires in near real-time. GOES-18 also helped determine fire size and
temperature.
* JULY 21, 2023: EARTH FROM ORBIT: NOAA SATELLITES MONITOR SEVERE WEATHER AND
SMOKE
As catastrophic flooding impacted the Northeast, skies across the region and
particularly along the central and eastern U.S. have also been affected by
heavy smoke from wildfires burning across Canada that has continued to drift
southward. NOAA satellites monitored conditions as the events unfolded.
GOES-16 measured water vapor that was transported in the atmosphere, and
monitored the storms that drenched the Northeast in near real-time. GOES-16
and 18 tracked the intense smoke from Canadian wildfires as it moved into the
central and eastern U.S., triggering air quality alerts. From fires to
floods, NOAA satellites help warn us of approaching hazards.
* JULY 13, 2023: SECOND QUARTER 2023 GOES-R/GEOXO NEWSLETTER
Geostationary Ground Services Sustainment team celebrates the award of the
sustainment contract. Photo credit: GOES-R
The GOES-R/GeoXO quarterly newsletter for April – June 2023 is now available.
It was, as ever, a busy quarter for us. The GOES-R ground system server
replacement effort concluded and we awarded the follow-on ground sustainment
contract. We continued environmental testing of the GOES-U satellite and the
mission integration efforts with the Falcon Heavy launch vehicle. On the
GeoXO front, work on the imager development contract began and we finished
the remaining Phase A Studies. The departures of 30+ year GOES alumni John
Fiorello and our longtime DPM Ed Grigsby, and the sadly too-soon passing of
our Review Manager Jonathan Gal-Edd are reminders to value and enjoy the
colleagues and friends we make along the way.
JUNE
* JUNE 30, 2023: EXTREME HEAT AND SEVERE WEATHER PLAGUE PARTS OF NORTH AMERICA
NOAA satellites have been watching the effects of a heat dome that settled
over Texas and parts of Mexico since early June 2023. The heat dome is
expected to spread northward and persist through July 4 with no relief in
sight. A heat dome is a ridge of high pressure that traps hot air. While the
heat dome is causing record-breaking temperatures in the south, it has also
led to severe weather. The edge of the heat dome meeting with cooler air can
trigger severe thunderstorms, tornados, and high winds. The NOAA/NASA Suomi
NPP and NOAA-20 satellites measured land surface temperature, revealing the
extent of the heat dome. Data collected by the satellites is used within
models such as the Global Forecast System to accurately predict conditions.
Meanwhile, GOES East watched the heat dome interact with cooler air in near
real-time as is seen with water vapor imagery. As these explosive storms
developed along the edge of the dome and traveled eastward, GOES tracked
their movement. GOES East also measured lightning within the storms and
infrared imagery from the satellite revealed the intensity of the storms.
* JUNE 21, 2023: EARTH FROM ORBIT: SUMMER SOLSTICE 2023
June 21, 2023, marks the start of astronomical summer in the Northern
Hemisphere. The summer solstice is the moment the hemisphere reaches its
greatest tilt toward the sun. NOAA’s GOES-16 and -18 satellites constantly
observe the same region of Earth, allowing a view of the terminator as it
moves across the Western Hemisphere. The terminator is the edge between the
shadows of nightfall and the sunlight of dusk and dawn. The slope of the
terminator curve changes with the seasons. The summer solstice is the longest
day, and shortest night, of the year in the Northern Hemisphere.
* JUNE 20, 2023: NOAA SATELLITES TRACKED HISTORIC LEVELS OF HARMFUL SMOKE,
IMPACTING MILLIONS IN THE EASTERN U.S.
GOES-16 imagery from June 6, 2023, shows a coastal low-pressure system
steering heavy smoke across the Northeast and Mid-Atlantic United States.
NOAA satellites, including GOES-16, provided critical data for air quality
forecasters when wildfires, burning near Quebec, Canada, sent billowing
plumes of smoke over the eastern United States. The satellite data allowed
NOAA scientists to estimate that more than 86 million people experienced fine
particulate pollution levels higher than the federal health standard. During
the early-June episode, NOAA satellite observations of the smoke helped
forecasters issue air quality alerts to protect public health. GOES data of
fine particulate pollution are increasingly being used in nowcasting mode to
provide warnings to the public.
* JUNE 20, 2023: LIGHTNING DETECTION: FROM GROUND TO SKY
GOES-16 GLM image from April 20, 2020, of the longest lightning flash on
record, which covered a horizontal distance of 477 miles.
Lightning may be stunning, but it is also a deadly, destructive force.
Meteorologists have studied lightning for centuries, working out its behavior
and developing ways to detect lightning strikes. Tools and techniques for
lightning detection have come a long way since Benjamin Franklin tested his
lightning rod, shifting our view of this powerful severe weather from the
ground to the sky. Satellites have allowed us to detect and map lightning
storms like never before – from space. The GOES-R Geostationary Lightning
Mapper (GLM) is the first optical lightning detector on a satellite in
geostationary orbit. NOAA began using the GLM in March 2017. In July 2018,
the National Weather Service started including its data in the determination
of operational weather forecasts.
* JUNE 12, 2023: WEATHERSATS AUGMENTED REALITY APP
Learn about the JPSS and GOES-R satellites that monitor extreme weather and
climate change in the new WeatherSats immersive AR app. It challenges you to
complete a series of missions, which will start with an interactive journey
into space where you’ll see the satellites orbiting Earth and view all of
their instruments up close. Play at home or play the app's six challenges at
the NASA Goddard Visitor Center! Available for download to your mobile device
from the Apple and Google app stores.
* JUNE 8, 2023: SMOKE FROM CANADIAN WILDFIRES BLANKETS U.S.
More than 400 fires are burning across Canada, blanketing regions throughout
North America with thick smoke. NOAA satellites are monitoring the smoke as
it drifts across the continent. Unusually hot and dry weather triggered an
early and intense start to the wildfire season in Canada and the country is
on track to have the worst wildfire season on record. Recently, smoke from
fires in Ontario and Quebec moved into the eastern U.S., triggering air
quality alerts across the region. According to NOAA’s Aerosol Watch, the
smoke caused a historic Code Red (unhealthy) daily Air Quality alert of 2.5
parts per million across New York, eastern Pennsylvania, and western
Connecticut on June 6, 2023. There was even a Code Purple (very unhealthy) in
some parts of New York City and Philadelphia. As of the morning of June 7,
historically high fine particulate concentrations were seen further south
into the Mid-Atlantic region, and reports from the ground stated limited
visibility and campfire-like smells. GOES East and GOES West are tracking the
billowing smoke and monitoring air quality in near real-time. JPSS satellites
are collecting data to help determine the height of the smoke plume, the
amount of smoke produced, and the direction it’s expected to move. Together,
NOAA satellites provide critical information for detecting and tracking fires
and alerting communities to poor air quality from smoke produced by the
blazes.
* JUNE 2, 2023: CAN LIGHTNING RESEARCH IMPROVE HURRICANE INTENSITY FORECASTS? A
Q&A WITH NOAA'S DR. STEPHANIE STEVENSON
Dr. Stephanie Stevenson
Dr. Stephanie Stevenson is a meteorologist at the NOAA/National Weather
Service National Hurricane Center (NHC) in Miami. Through her ground-breaking
research and efforts, new applications using GOES-R Geostationary Lightning
Mapper (GLM) data are being used as guidance for NHC forecasts as well as in
media and decision-support briefings. With 2023’s Atlantic Hurricane Season
officially underway, NESDIS recently interviewed Dr. Stevenson to learn more
about her research and what it means for the future of hurricane tracking and
forecasting.
MAY
* MAY 31, 2023: TIME-LAPSE OF SOLAR CYCLE 25 DISPLAYS INCREASING ACTIVITY ON
THE SUN
GOES-16 SUVI imagery alongside the progression of the number of sunspots from
December 2019 through April 2023.
Solar Cycle 25 has ramped up much faster than scientists predicted producing
more sunspots and eruptions than experts had forecast. Tracking and
predicting the sun’s solar cycles gives a rough idea of the frequency of
space weather storms of all types – from radio blackouts to geomagnetic
storms and solar radiation storms – and it’s used by many industries to gauge
the potential impact of space weather on Earth. A new time lapse animation
shows GOES-16 Solar Ultraviolet Imagery (SUVI) during Solar Cycle 25 from
December 2019 through April 2023 alongside the progression of the number of
sunspots. SUVI images the solar corona in six different extreme ultraviolet
wavelengths. NOAA’s space weather forecasters use SUVI imagery to issue
alerts and watches for space weather storms.
* MAY 31, 2023: 2023 GOES VIRTUAL SCIENCE FAIR TOP PROJECTS ANNOUNCED
2023 top GOES high school project: Verifying Flash Flood Advisory Boundary
Locations using GOES-16 ABI Imagery: A Case Study of Tropical Storm Beta
(2020)
The Cooperative Institute of Meteorological Satellite Studies at the
University of Wisconsin-Madison announced the winning projects for the 2023
GOES Virtual Science Fair. During the virtual science fair, middle and high
school students (grades 6-12) worked with GOES satellite data to investigate
weather and natural hazards and conveyed their projects with scientific
posters. High school submissions also required a short video where students
explain their project, similar to a poster session at a professional
conference. By offering authentic STEM (science, technology, engineering and
math) engagement to a pre-college audience, this activity serves as a
pipeline to society’s scientists of tomorrow and NOAA’s future workforce
* MAY 25, 2023: EARTH FROM ORBIT: POPOCATÉPETL VOLCANO ERUPTS IN MEXICO
Since May 15, 2023, NOAA satellites have been watching Mexico’s Popocatépetl
Volcano exhibit activity ranging from tremors to spewing ash. Popocatépetl,
Aztec for smoking mountain, is located 45 miles southeast of Mexico City.
With about 25 million people living within 60 miles of Popocatépetl, it is
considered one of the most dangerous volcanoes in the world. Geostationary
satellites, like GOES-16 and GOES-18, are the primary tool for monitoring
volcanic clouds. GOES-16 observed Popocatépetl’s ash plumes in near real-time
and monitored hazardous sulfur dioxide from the volcano. JPSS satellites
measured smoke, ash and dust from the volcano. Together, NOAA satellites help
monitor volcanoes and the risks they pose.
* MAY 11, 2023: EARTH FROM ORBIT: WILDFIRES RAGE IN WESTERN CANADA
In early May 2023, fires ignited across western Canada due to unusually hot
and dry weather. NOAA satellites watched as the fires raged, burning about
one million acres. GOES-18 monitored the spread of the fires and smoke across
the region. The ABI instrument on GOES-18 observed the formation of
pyrocumulonimbus clouds from intense fires in Alberta. The data collected by
NOAA satellites help responders forecast what areas will be impacted and
manage the wildfires. As the Northern Hemisphere heats up, NOAA satellites
will keep watch for wildfires.
* MAY 11, 2023: NOAA AWARDS GEOSTATIONARY GROUND SYSTEM SUSTAINMENT SERVICES
CONTRACT
Today, NOAA awarded the Geostationary Ground Sustainment Services (GGSS)
contract to L3Harris Technologies Inc. of Palm Bay, Florida. The five-year
Indefinite Delivery/Indefinite Quantity (IDIQ) contract will provide
sustainment services to extend the functions of the ground system that
supports NOAA’s GOES-R Series. This contract provides for an indefinite
quantity of supplies and services during the contract ordering period from
May 11, 2023, through May 10, 2028. Individual supplies and service
requirements will be defined at the task order level. The maximum value of
this IDIQ contract is $275,169,157. The work will be performed at NOAA
facilities located in Suitland, Maryland; College Park, Maryland; Wallops
Island, Virginia; and Fairmont, West Virginia; and at the L3Harris facility
in Melbourne, Florida.
* MAY 4, 2023: EARTH FROM ORBIT: PREPARING FOR HURRICANE SEASON
As spring heads toward summer, NOAA satellites are ready for this year’s
upcoming hurricane season. NOAA satellites monitor the conditions that spawn
hurricanes and provide early warning that a storm is forming. GOES East and
West monitor hurricanes as they develop and track their movements in near
real-time. GOES satellites measure the temperature of cloud tops and the
amount of water vapor present within a system, and also provide wind
estimates. They also monitor lightning within a storm. NOAA satellites also
aid emergency response to landfalling hurricanes by mapping the extent,
damage and duration of flood events. Together, NOAA satellites are prepared
to provide vital information to forecasters and help protect life and
property throughout the 2023 hurricane season and beyond.
* MAY 3, 2023: GOES-U COMPLETES SOLAR ARRAY DEPLOYMENT TEST
The GOES-U solar array fully deployed. Photo credit: Lockheed Martin
GOES-U, the fourth and final satellite in NOAA’s GOES-R Series, recently
completed a successful test deployment of its solar array to ensure it will
function properly in space. This critical test verified that the satellite's
large, five-panel solar array — which is folded up when the satellite is
launched — will properly deploy when GOES-U reaches geostationary orbit.
GOES-U’s solar array will convert energy from the sun into electricity to
power the entire satellite, including the instruments, computers, data
processors, sensors, and telecommunications equipment. GOES-U is scheduled to
launch in 2024.
APRIL
* APRIL 28, 2023: EARTH FROM ORBIT: LARGE GEOMAGNETIC STORM HITS EARTH
On April 21, 2023, NOAA satellites detected a coronal mass ejection erupting
from the sun, which hurled plasma at two million miles per hour toward Earth.
This eruption produced a geomagnetic storm on Earth. GOES-16’s Solar
Ultraviolet Imager (SUVI) instrument observed the event as it occurred, while
the DSCOVR satellite measured the solar winds the storm produced. This
allowed NOAA to issue warnings for possible impacts from the storm.
Geomagnetic storms can affect electrical grids, spacecraft, radio
frequencies, GPS signals, and astronauts in space. On April 23, the particles
reached Earth’s upper atmosphere and caused an aurora in both the Northern
and Southern Hemispheres. This is the third severe geomagnetic storm since
Solar Cycle 25 began in 2019. As the sun’s activity continues to ramp up,
NOAA satellites will be watching for hazardous space weather.
* APRIL 21, 2023: EARTH FROM ORBIT: HAPPY EARTH DAY 2023
Since 1970, NOAA satellites have been monitoring Earth’s weather,
environment, oceans, and climate. This Earth Day, we have a lot to celebrate.
Over the past year, NOAA has added two new satellites to its Earth-observing
fleet and contributed an instrument to a mission that will help us have a
better understanding of Earth’s physical and biological environment. On Earth
Day, we celebrate the critical information NOAA satellites provide to help us
stay safe and the beautiful imagery they share of our planet. They see it
all: hurricanes, severe thunderstorms, lightning, fires, dust storms, smoke,
fog, volcanic eruptions, vegetation, snow and ice cover, flooding, sea and
land surface temperature, ocean health and more. They can even track ship
traffic and power outages. At NOAA, each day is Earth Day.
* APRIL 11, 2023: FIRST QUARTER 2023 GOES-R/GEOXO NEWSLETTER
GOES-U acoustics testing. Photo credit: Lockheed Martin
The GOES-R/GeoXO quarterly newsletter for January – March 2023 is now
available. 2023 is off to an exciting start! We are just a little over a year
away from the GOES-U launch, the final launch for the GOES-R Series. GOES-U
completed mechanical environments testing and will next undergo
electromagnetic interference/electromagnetic compatibility testing. We held
our first GOES-R summit since 2019 and had the opportunity to collaborate in
person with our colleagues from across the country. The newly operational
GOES-18 satellite monitored a deluge of atmospheric rivers affecting the West
Coast and an increasingly active sun. On GeoXO, we took our first step into
implementation, with the award of the development contract for the imager,
the primary instrument on our next-generation satellite system.
MARCH
* MARCH 30, 2023: EARTH FROM ORBIT: VIOLENT STORMS TEAR THROUGH THE SOUTH
Beginning on March 24, 2023, NOAA satellites monitored severe storms that
caused widespread damage from Texas to the Mid-Atlantic. The storms produced
high winds, hail, flooding, and tornadoes. High winds and 38 tornadoes were
reported when the storms moved through Mississippi, Alabama and Tennessee.
The town of Rolling Fork, Mississippi was struck by an EF-4 tornado that
killed 26 people in total, injured dozens more, and damaged buildings and
utilities. GOES-16 (GOES East) monitored the storm in near real-time as it
barreled across the Southeast.
* MARCH 24, 2023: EARTH FROM ORBIT: MORE HEAVY RAIN, SNOW, AND WIND HITTING
WESTERN U.S.
After tracking a series of atmospheric rivers that have drenched California
this year, NOAA satellites monitored the latest storm to begin impact the
state on Mar. 19, 2023. Rain and snow triggered flash flooding, caused
numerous evacuations and left over 350,000 without power. The atmospheric
river fueled a mid-latitude cyclone that led to the formation of a
hurricane-like eye when two low pressure areas converged over San Francisco.
NOAA satellites provided vital information about airborne moisture for more
accurate weather forecasts and to predict flood risks and manage water
resources.
* MARCH 2, 2023: EARTH FROM ORBIT: MONUMENTAL U.S. STORM BRINGS SEVERE WINTER
WEATHER COAST TO COAST
Since mid-February 2023, winter weather has impacted the continental U.S.
from California to Maine. In Southern California, the storm brought blizzard
conditions to the San Bernardino and San Gabriel mountains as well as heavy
rainfall to lower elevations. As the storm system continued eastward, snow
and driving winds caused road closures and drifting snow across the Plains.
Further south in Kansas and Oklahoma, tornadoes downed power lines, damaged
property, and caused injuries. Additional tornadoes were reported in central
and northeastern Illinois. The storm also brought heavy snow to the
Northeast. NOAA satellites provided complementary measurements for a complete
picture of this monumental storm and played a crucial role in tracking the
storms across the U.S., alerting those in harm’s way.
FEBRUARY
* FEB. 21, 2023: EARTH FROM ORBIT: TROPICAL CYCLONE FREDDY BREAKS RECORDS
BEFORE LASHING MADAGASCAR
On Feb. 21, 2023, Tropical Cyclone Freddy made landfall on Madagascar. Freddy
formed on Feb. 5 near Indonesia and trekked more than 4,000 miles before
hitting Madagascar. Freddy is one of only four storms on record to cross the
Indian Ocean from east to west. It is also the first in the Southern
Hemisphere to undergo four separate rounds of rapid intensification. At its
strongest, Freddy had maximum sustained winds of more than 160 miles per
hour, equivalent to a Category 5 hurricane. NOAA satellites and those from
our international partners monitored the storm as it traversed the Indian
Ocean and made landfall in Madagascar.
* FEB. 9, 2023: EARTH FROM ORBIT: NOAA SATELLITES TRACK BLAZING WILDFIRES IN
CHILE
At least 231 wildfires have been blazing through south-central Chile since
Feb. 3, 2023. The region is experiencing a “mega drought” with a decade-long
period of dry weather. NOAA satellites are monitoring the fires as hot and
dry weather persists. As of Feb. 8, 231 fires have burned more than 741,315
acres of land, making it the second worst year for acreage burned in Chile.
GOES-16 and GOES-18 observed the movement of smoke from the fires in
near-real time, while identifying new fires. The satellites also help
determine a fire’s size and temperature. NOAA-20 and Suomi NPP provide
detailed information on fire conditions. The satellites can detect smaller
and lower-temperature fires and track wildfires in remote regions. Together,
NOAA satellites provide critical and timely information used by fire crews,
first responders and air traffic controllers.

* FEB. 2, 2023: EARTH FROM ORBIT: ROPE CLOUDS
On Jan. 25, 2023, NOAA satellites captured an unusually long and long-lived
rope cloud produced by a cold front over the Gulf of Mexico. A rope cloud is
a very long, narrow, rope-like band of cumulus cloud formations. Generally
associated with a cold front or a land-sea breeze front, rope clouds tend to
form at the dividing line between cooler and warmer air. In this case, the
rush of cool, dense air from the cold front pushed the warm, maritime air
from the Gulf of Mexico upward, allowing water vapor to condense and the
cloud to form. Satellite imagery can capture rope clouds, indicating a
potentially changing weather pattern.
JANUARY
* JANUARY 25, 2023: EARTH FROM ORBIT: ATMOSPHERIC RIVERS HIT THE WEST COAST
From late Dec. 2022 into Jan. 2023, a series of nine “atmospheric rivers”
dumped a record amount of rain and mountain snow across the western U.S. and
Canada, hitting California particularly hard. More than 32 trillion gallons
of water rained down across the state, and the moisture also pushed into much
of the Intermountain West. The San Francisco Bay area experienced its wettest
three-week period in 161 years. Atmospheric rivers are long, narrow belts of
moisture that move through the atmosphere. They can deliver tremendous
amounts of rain, and high-elevation snow. This deluge of rain can provide
relief for drought-stricken areas but also trigger flash flooding and
mudslides. NOAA satellites help forecast these rivers in the sky and monitor
the weather conditions they bring.
* JANUARY 23, 2023: NOAA SATELLITES HELPED SAVE 397 LIVES IN 2022
A graphic showing 3 categories of satellite-assisted rescues that took place
in 2022: Of the 397 lives saved, 275 people were rescued at sea, 42 were
rescued from aviation incidents and 80 were rescued from incidents on land.
NOAA satellites, which are crucial in weather and climate forecasts, helped
rescue 397 people from potentially life-threatening situations throughout the
U.S. and its surrounding waters in 2022. NOAA’s polar-orbiting and
geostationary satellites are part of the global Search and Rescue Satellite
Aided Tracking system, or COSPAS-SARSAT, which uses a network of U.S. and
international spacecraft to detect and locate distress signals sent from
emergency beacons from aircraft, boats and handheld Personal Locator Beacons
(PLBs) anywhere in the world. Of the 397 U.S. rescues last year, 275 were
water rescues, 42 were from downed aircraft and 80 were on land involving
PLBs. Florida had the most SARSAT rescues with 106, followed by Alaska with
56 and Utah with 20.
* JANUARY 13, 2023: FOURTH QUARTER 2022 GOES-R/GEOXO NEWSLETTER
RGB Developers Workshop participants.
The GOES-R/GeoXO quarterly newsletter for October – December 2022 is now
available. The GOES-R and GeoXO programs achieved new heights in 2022. We
launched GOES-T, now known as GOES-18, completed on-orbit checkout, executed
two GOES-17 and GOES-18 data interleave periods, and handed the satellite
over to NOAA’s Office of Satellite and Product Operations. GOES-18 became
NOAA’s operational GOES West satellite on Jan. 4, 2023. GOES-U is progressing
toward its planned launch next spring, completing thermal vacuum testing and
preparing for mechanical testing. And the future of NOAA’s geostationary
satellite observations is assured, with the approval of the GeoXO Program.
* JANUARY 04, 2023: NOAA’S GOES-18 IS NOW GOES WEST
NOAA’s operational satellite fleet has a new member. GOES-18 entered service
as GOES West on Jan. 4, 2023. The milestone comes after a Mar. 1, 2022,
launch and post-launch testing of the satellite’s instruments, systems, and
data. GOES-18 replaces GOES-17 as GOES West, located 22,236 miles above the
equator over the Pacific Ocean. GOES-17 will become an on-orbit standby. In
its new role, GOES-18 will serve as NOAA's primary geostationary satellite
for detecting and monitoring Pacific hurricanes, atmospheric rivers, coastal
fog, wildfires, volcanic eruptions, and other environmental phenomena that
affect the western contiguous United States, Alaska, Hawaii, Mexico, and
Central America. GOES-18 joins GOES-16 (GOES East) in operational service.
Together the two satellites watch over more than half the globe, from the
west coast of Africa to New Zealand and from near the Arctic Circle to the
Antarctic Circle.
