Atmospheric InfraRed Sounder (AIRS): Science and measurement requirements
Abstract
The Atmospheric Infrared Sounder (AIRS) is a high spectral resolution sounder selected as a facility instrument on the Earth Observing System (EOS). The complete infrared coverage of AIRS from 3.3 micrometers to 15.4 micrometers, together with the capabilities of the Advanced Microwave Sounding Unit (AMSU), will provide an all-weather observational capability for a large number of atmospheric and surface parameters. Measurements from AIRS will satisfy the requirements of general circulation modeling in accuracy, resolution, and coverage. It will provide day and night global coverage of the Earth twice a day with a footprint of 13.5 km (1.1 deg) at nadir from the 705 km orbital altitude of Eos. Measurement requirements, AIRS measurement specifications, the hardware implementation concept, and the AIRS ground-based data analysis concept are presented.
