Aqua/AIRS L2 Standard Physical Retrieval (AIRS+AMSU) V7.0 at GES DISC
The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. The AIRS combination with the Advanced Microwave Sounding Unit (AMSU) constitutes an innovative atmospheric sounding group of infrared and microwave sensors. The AIRS Standard Retrieval Product consists of retrieved estimates of cloud and surface properties, plus profiles of retrieved temperature, water vapor, ozone, carbon monoxide and methane. Estimates of the errors associated with these quantities are also be part of the Standard Product. The temperature profile vertical resolution is 28 levels total between 1100 mb and 0.1 mb, while moisture profile is reported at 14 atmospheric layers between 1100 mb and 50 mb. The horizontal resolution is 50 km. An AIRS granule has been set as 6 minutes of data, 30 footprints cross track by 45 lines along track. There are 240 granules per day, with an orbit repeat cycle of approximately 16 day.

- Quality The quality of data products, described in the associated references, provide information about numerous validation studies conducted and papers written documenting the excellence of the products using radiosondes, ground truth, other satellites, and model analysis products. Each variable contains a flag indicating the quality of the value. The three options for this quality flag are: 0 for best quality, 1 for good quality, 2 for do not use. This product stopped after September 24, 2016 as the power to the AMSU-A2 instrument on Aqua was lost. For data after this time use AIRS2RET.7.0 (AIRS-only) .
