Description:

AIRS data are critical in the monitoring of Earth’s atmosphere, improving weather forecasts and enhancing our understanding of Earth’s climateMore ›MoreThe AIRS Science Team and NASA GES DISC, are pleased to announce the release of Version 7 Level 2 and Level 3 data products.More ›MoreNow updated through 2019, AIRS data have allowed for major contributions in the science of weather, climate, composition and air qualityMore ›MoreA fully automated system to detect sulfur dioxide and dust, markers of volcanic eruptions, is now operational.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 toassess the skill of climate modelsand in applications ranging from volcanic plume detection to drought forecasting.learn moreData from AIRS has advanced our understanding of Earth s atmosphere, making significant contributions in weather, climate and composition science.Mission & InstrumentThe AIRS instrument has provided the most significant increase in forecast improvement in this time range of any other single instrumentNavy Vice-Admiral (ret.) and former NOAA Administrator Conrad C. LautenbacherLaunched 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 ›AIRS' observations from Earth orbit show high-altitude concentrations of the gas that are more than 10 times typical amounts.Aircraft find atmospheric gravity waves bending toward Antarctica’s polar vortex, and data from AIRS are used to help trace the waves.Using ground and satellite data, scientists found that human activity is causing a significant increase in dry air over the Amazon rainforest.AIRS Project Scientist Eric Fetzer discusses climate trends the Atmospheric Infrared Sounder instrument has detected over the past 17 years.
