Data Center Description
The AIRS Project at JPL provides a wide range of services to the AIRS user community. Our first and foremost responsibility is to keep the AIRS and AMSU instruments operating and their raw data products calibrated. Several agencies use the AIRS data operationally for weather forecast predictions. Any gaps in data or changes in the calibration will result in troublesome delays to recalibrate and possibly reduce forecast accuracies or affect climate trending. For this reason, we attempt to make no changes to the raw calibrated radiance data products and have not done so since launch.
The development of AIRS products is a team activity. The Standard Data Products (Level 2) are produced from one "Product Generation System" (PGS). JPL integrates the algorithms and source code from several members of the NASA AIRS Science Team into the PGS then tests and validates the products. The PGS is then sent to NOAA and the GSFC DAAC for operational processing and distribution. All products are released to the public regardless of their validation status. We have an open-door policy on the AIRS Project since we believe that the products can only improve if they are diagnosed by a wide range of users. Please read the validation report prior to use of any of the AIRS data products from a particular version of the PGS to be sure the data are suitable for scientific investigations.
