Advances Our Understanding of Earth’s Climate

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite has been scanning Earth for 20 years and now has a long enough record to help support climate change research. AIRS data on Earth’s atmosphere are improving weather forecasts and advancing our understanding of Earth’s climate. AIRS' infrared technology creates 3D maps of air and surface temperature, water vapor, and cloud properties
