AIRS: The Atmospheric Infrared Sounder

A major objective of the study of global change is the development of accurate long-term data sets of the Earth's climate system. To accomplish this, a wide range of observations will be carried out by the NASA Earth Observing System (EOS). The Atmospheric Infrared Sounder (AIRS) is a facility instrument selected by NASA to fly on the first polar orbiting platform, EOS-A1. The same platform will also carry the NOAA operational Advanced Microwave Sounding Unit (AMSU-A) and the Microwave Humidity Sounder (MHS). The AIRS/AMSU/MHS system will provide both new measurements not previously achievable and measurements with a greater degree of accuracy and resolution than are currently available.
