Welcome to the Goddard Earth Sciences DAAC AIRS data support web site. The DAAC will provide end-to-end support for data products generated from the suite of AIRS/AMSU/HSB instrumentation onboard the Aqua satellite.

AIRS, AMSU, and HSB constitute an innovative atmospheric sounding group of visible, infrared, and microwave sensors that provide measurements for temperature at an accuracy of 1 ° C in layers 1 km thick and humidity with an accuracy of 20 % in layers 2 km thick in the troposphere.

The increased accuracy of the temperature and humidity profiles derived from AIRS/AMSU/HSB should enable improved forecasts from meteorological prediction models, and represents an important component of satellite-based measurements designed to detect and quantify global climate change.

Level 3 products are coming soon:

In order to satisfy the needs of those interested in atmospheric dynamics, climate variability and change, and the hydrological cycle, the AIRS Science Team will soon release gridded AIRS level 3 products. The plan is to have three types of level 3 products, daily, 8-day and monthly, and search for the best possible level 3 products through a process of interaction with the research community.

New SAMPLE AIRS LEVEL 3 PRODUCTS AVAILABLE

News...
July 31, 2004:  Reprocessing of AIRS/AMSU/HSB Level 1B and Level 2 products is totally completed at the GDAAC (until the next reprocessing campaign).

Mar 10, 2004: V3.0.10.0 release documentation is available.

Feb 10, 2004: In response to unusually intense solar activity during late October and early November 2003, the AMSU-A and AIRS instruments on Aqua were powered off as a safety measure on October 29, 2003 at 02:00 UT. Data collection for AMSU-A was resumed on November 4, 2003 at 5:59 UT. Data collection for AIRS was resumed on November 19, 2003 at 06:18 UT. Slight changes in channel responses for the AIRS instrument necessitated release of V3.0.10.0, a newer version of AIRS/AMSU-A Science Processing Software. No other changes were included in this release.

A detailed description of the impact of the solar event on the AIRS suite of instruments, the AIRS Project Team response to that event, and assessment of V3.0.10.0 will be released within the next few weeks.

Sep 24,2003: GES DISC DAAC is reprocessing the AIRS data for September 1, 2002 to present. Reprocessing will be performed by the order of the following data date: 12/2002, 02/2003, 08/31/2002 - 11/2002, 01/2003, 03/2003 and forward. The reprocessed data will be available to the public as soon as it is produced.
