AIRS
The anomaly found in the AVI (Global Forecast System) data that GES DISC receives from NOAA to produce Aqua AIRS Level 2 products has been addressed. The production of level 2 and level 3 products for Aqua AIRS has been resumed.
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 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.
