Summary
Abstract: The Atmospheric Infrared Sounder (AIRS) is a facility instrument 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. AIRS data will be generated
continuously. Global coverage will be obtained twice daily (day and night) on a
1:30pm sun synchronous orbit from a 705-km altitude.

The AIRS Visible/Near Infrared (VIS/NIR) Level 1B QA Subset contains Quality
Assurance (QA) parameters that a may use of filter AIRS VIS/NIR Level 1B
radiance data to create a subset of analysis. It includes "state" that user
should check before using any VIS/NIR Level 1B data radiance and "glintlat",
"glintlon", and "sun_glint_distant" that users can use to check for possibility
of solar glint contamination.

AIRS VIS/NIR Level 1B radiance data can be found in AIRVBRAD.

(The Shortname for this product is AIRVBQAP)
