AIRS

The AIRS/AMSU/HSB suite of instruments is flying on board of Aqua satellite, and thus their "overpass" pattern is this of Aqua.

The  AIRS/AMSU/HSB suite 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 200 mK. This product is the most accurate and stable set of hyperspectral infrared radiance spectra measurements made in space to date, and it 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 (Level-2 only), CO and CH4.

The accuracy of the temperature and humidity profiles derived from AIRS/AMSU/HSB is recognized as improving forecasts from meteorological prediction models. NOAA administrator Lautenbacher has reported that "the AIRS instrument has provided the most significant increase in forecast improvement in this time range of any other single instrument." Currently researchers are using AIRS data products to validate climate models and to test their representations of critical climate feedbacks.

The AIRS Data Support at the GES DISC DAAC provides science and data support to assist others in understanding, ordering, and using the AIRS/AMSU/HSB data products.
