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.

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. |
