ABOUT AIRS



AIRS, the Atmospheric Infrared Sounder on NASA's Aqua satellite, gathers
infrared energy emitted from Earth's surface and atmosphere globally, every day.
Its data provides 3D measurements of temperature and water vapor through the
atmospheric column along with a host of trace gases, surface and cloud
properties. AIRS data are used by weather prediction centers around the world to
improve their forecasts. They are also used to assess the skill of climate
models and in applications ranging from volcanic plume detection to drought
forecasting.

MISSION & INSTRUMENT

The AIRS instrument has provided the most significant increase in forecast
improvement in this time range of any other single instrument Navy Vice-Admiral
(ret.) and former NOAA Administrator Conrad C. Lautenbacher

Launched into orbit on May 4, 2002 aboard NASA's Aqua satellite, the Atmospheric
Infrared Sounder, or AIRS, is enhancing our understanding of Earth's weather and
climate. AIRS is one of six instruments aboard NASA's Aqua satellite, which in
turn is part of a constellation of satellites that make up NASA's Earth
Observing System. AIRS along with its partner microwave instrument the Advanced
Microwave Sounding Unit (AMSU-A), represents the most advanced atmospheric
sounding system ever deployed in space. Together these instruments observe the
global water and energy cycles, climate variation and trends, and the response
of the climate system to increased greenhouse gases.

AIRS uses cutting edge infrared technology to create three-dimensional maps of
air and surface temperature, water vapor, and cloud properties. With 2378
spectral channels, AIRS has a spectral resolution more than 100 times greater
than previous infrared sounders and provides more accurate information on the
vertical profiles of atmospheric temperature and moisture. AIRS can also measure
trace greenhouse gases such as ozone, carbon monoxide, carbon dioxide, and
methane.

NEWS & FEATURES

While record-breaking heat enveloped the Pacific Northwest in June 2021, other
parts of the Northern Hemisphere also saw early-summer temperatures climb.

A Scorcher in Siberia and Europe
Evaporation plays an important role in the global water and energy cycles and
therefore in climate change. AIRS data were used in a study to help quantify
evaporation over the Southern Ocean, where the Antarctic sea ice coverage has a
large annual cycle.

Dry Ice: How Expanding Antarctic Sea Ice is Drying the Atmosphere Over the
Southern Ocean
Our planet is constantly trying to balance the flow of energy in and out of
Earth’s system, but human activities are throwing that off balance, causing our
planet to warm in response. AIRS data were used in this study to parse out how
much of the total energy change is caused by humans.

Direct Observations Confirm that Humans are Throwing Earth's Energy Budget off
Balance
In January 2022, the Hunga Tonga-Hunga Ha’apai volcano erupted twice, sending
plumes of ash, steam, and gas more than 30 kilometers high and causing
unprecedented gravity, shock, and sound waves to move through the global
atmosphere. AIRS observations of atmospheric waves and volcanic plumes created
by the eruptions have led to the insights described below.

AIRS captures views of Hurricane Ida before and after landfall on August 29,
2021.
