Daily atmosphere support data, 1-degree grid (Aqua AIRS+AMSU)

AIRS/Aqua L3 Daily Support Product (AIRS+AMSU) 1 degree x 1 degree V006 (AIRX3SPD) at GES DISC
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. Daily, globally gridded atmospheric fields at 1-degree resolution, including supporting and intermediate values that aren't fully quality-controlled.

How it's made. Derived from the AIRS infrared sounder and AMSU on the Aqua satellite and gridded into daily 1-degree maps; this support version may include values from failed retrievals.

How & where you'd use it. A specialized companion to the main AIRS daily products, mainly used by researchers who need the extra input or intermediate fields, with caution about quality.

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.
