AIRX2RET data sample product
The AIRS Standard Retrieval Product consists of retrieved estimates of cloud and surface
properties, plus profiles of retrieved temperature, water vapor, and ozone, and a flag indicating
the presence of cloud ice or water. Estimates of the errors associated with these quantities
will also be part of the Standard Product. The profile vertical resolution is 28 points
total between 1000 mb and .02 mb. The Standard Product contains quality assessment flags
in addition to retrieved quantities. The Standard Product will be generated at all
locations where atmospheric soundings are taken.
An AIRS granule has been set as 6 minutes of data. This will normally correspond to
approximately 1/15 of an orbit but exactly 45 scanlines of AMSU-A data or 135 scanlines
of AIRS and HSB data.
The Standard Product has Surface skin temperature (K), Surface air temperature (K),
Air temperature (K), Water vapor mass mixing ratio (gm/kg dry air),
Water vapor saturation mass mixing ratio (gm/kg dry air), Total water (kg/ m**2),
Ozone volume mixing ratio (micromoles/mole), Total ozone (Dobson units),
IR surface emissivities, IR surface reflectivities,
Microwave surface brightness temperature, Microwave emissivity at 50.3 GHz,
Total cloud water (kg/m**2), Cloud top temperature (K),
Cloud top pressure (mb), Cloud fraction (0.0 - 1.0),
Geopotential heights (m above mean sea level),
and Geopotential height of surface (m above mean sea level).
