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 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 IR Level 1B QA Subset contains Quality Assurance (QA)
parameters that a user of may use to filter AIRS IR Level 1B radiance
data to create a subset of analysis. QA parameters indicate quality of
granule-per-channel, scan-per-channel, field of view, and channel and
should be accessed before any data of analysis. It also contains
"glintlat", "glintlon", and "sun_glint_distant" that users can use to
check for possibility of solar glint contamination.
AIRS IR Level 1B radiance data can be found in AIRIBRAD.
(The Shortname for this product is AIRIBQAP_NRT).
