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. learn more MEETINGS & ANNOUNCEMENTS * NASA AIRS/Sounder Virtual Science Team Meeting set for September 13-15.

WEATHER, CLIMATE AND COMPOSITION SCIENCE DATA FROM AIRS HAS ADVANCED OUR UNDERSTANDING OF EARTH'S ATMOSPHERE, MAKING SIGNIFICANT CONTRIBUTIONS IN WEATHER, CLIMATE AND COMPOSITION SCIENCE. MORE 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. more about the mission › more about the instrument › NEWS & FEATURES 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 Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA. Data from AIRS were included in the analysis. 2020 Tied for Warmest Year on Record, NASA Analysis Shows AIRS' observations from Earth orbit show high-altitude concentrations of the gas that are more than 10 times typical amounts. NASA Monitors Carbon Monoxide From California Wildfires AIRS captured the progression of this slow-moving heat dome across the region from June 21 to 30, 2021. NASA's AIRS Tracks Record-Breaking Heat Wave in Pacific Northwest 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.
