Supporting atmosphere data (Aqua AIRS, monthly, 1 degree)

AIRS/Aqua L3 Monthly Support Product (AIRS-only) 1 degree x 1 degree V006 (AIRS3SPM) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. Monthly, gridded supporting atmospheric readings derived from the AIRS sounder — similar to its main products but including fields that aren't fully validated or are intermediate values.

How it's made. Produced from the AIRS infrared instrument on NASA's Aqua satellite, averaged into monthly maps at 1-degree resolution.

How & where you'd use it. A specialist product for researchers who need the extra or intermediate fields; it should be used with caution since some values come from retrievals that may have failed quality checks.

Official description

The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. The L3 support products are similar to the L3 standard products but contain fields which are not fully validated, or are inputs or intermediary values. Because no quality control information is available for some of these fields, values from failed retrievals may be included.
