Atmospheric Infrared Sounder The term 'Atmospheric Infrared Sounder' as it applies to the area of Earth observation can be defined as ' Advanced sounding instrument selected to fly on the EOS-PM1 mission (intermediate-sized, sun-synchronous, morning satellite) in the year 2000. It will retrieve vertical temperature and moisture profiles in the troposphere and stratosphere. Designed to achieve temperature retrieval accuracy of 1 degree C with a 1 km vertical resolution, it will fly with two operational microwave sounders. The three instruments will constitute an advanced operational sounding system, relative to the TIROS Operational Vertical Sounder (TOVS) currently flying on NOAA Polar-orbiting satellites. See Earth Observing System, TIROS-N/NOAA '.
