Satellite Instruments
AIRS (Atmospheric Infrared Sounder) is one of six instruments on board the Aqua satellite, part of NASA's Earth Observing System. AIRS provides observations of radiance in 2378 spectral bands in the visible and infrared. Spatial resolution of the data is 2.3 km for visible and near IR, and 13.5 km for IR. The AIRS/AMSU/HSB suite of instruments constitutes an innovative atmospheric sounding system of infrared, microwave and visible sensors. The infrared radiance data product is stable to 10 mK/yr and accurate to better than 250 mK. This product is the most accurate and stable set of hyperspectral infrared radiance spectra measurements made in space to date, and its meets the criteria identified by the National Research Council for climate data records. The geophysical products provide daily global temperature profiles at an accuracy of 1 K per 1 km thick layer in the troposphere and moisture profiles at an accuracy of 20% per 2 km thick layer in the lower troposphere (20% 60% in the upper troposphere). With the Version 5 release the Level-2 and Level-3 products also include the burden and profiles of the minor gases: O3, CO and CH4 as well as the mole fraction mid-tropospheric CO2. AIRS was conceived and built by the Jet Propulsion Laboratory, and a rich collection of information is available at the mission web site - http://airs.jpl.nasa.gov//
