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. Global coverage will be obtained twice daily (day and night) on a 1:30pm sun synchronous orbit from a 705-km altitude. For processing convenience, the data is divided into 6-minute files for Level 1 and 2 data.
Version 5 Level 1B Calibrated infrared and Vis/Near IR radiance data set, microwave brightness temperature data set and associated quality assurance subsets.
Version 5 Level 3 daily, 8-day and monthly standard retrieval data set and 5-day and monthly distributional summaries of Level 2 standard data set derived from AIRS and AMSU. Statistical Mean, Std Dev and Input Counts for Surface and Atmospheric Quantities in a 1x1 Lat/Lon Grid Box.
Version 5 Level 3 daily, 8-day and monthly standard retrieval data set and 5-day and monthly distributional summaries of Level 2 standard data set derived from AIRS, AMSU and HSB. Statistical Mean, Std Dev and Input Counts for Surface and Atmospheric Quantities in a 1x1 Lat/Lon Grid Box.
