The Atmospheric Infrared Sounder, AIRS, was launched aboard the Aqua spacecraft in 2002 as part of NASA’s Earth Observing System Afternoon Constellation of satellites known as the “A-Train.” AIRS hyperspectral observations are used to produce global maps of temperature and water vapor profiles, and numerous trace gases including carbon dioxide, ozone, carbon monoxide, and methane. AIRS data improve weather prediction, validate climate models, and improve our understanding of the processes affecting weather and climate and the global transport of greenhouse gases worldwide.
