The AIRS (Atmospheric Infrared Sounder) instrument is a high spectral resolution grating spectrometer containing 2378 infrared channels in the 3.74 to 15.4 micron spectral range for obtaining atmospheric temperature profiles and a variety of additional Earth/atmosphere products. AIRS is centered on measuring accurate temperature and humidity profiles throughout the atmosphere. AIRS also provides four visible/near-infrared channels (0.4 - 1.0 μm) to characterize cloud and surface properties.
