Summary

Abstract: The AIRS Level 3 Monthly Gridded Retrieval Product contains standard retrieval means, standard deviations and input counts. Each file covers a calendar month. The mean values are simply the arithmetic means of the daily products, weighted by the number of input counts for each day in that grid box.

The geophysical parameters have been averaged and binned into 1 x1 deg grid cells, from -180.0 to +180.0 deg longitude and from -90.0 to +90.0 deg latitude. For each grid map of 4-byte floating-point mean values there is a corresponding 4-byte floating-point map of standard deviation and a 2-byte integer grid map of counts. The counts map provides the user with the number of points per bin that were included in the mean and can be used to generate custom multi-day maps from the daily gridded products.

The geophysical parameters are: Skin Temperature, Surface Air Temperature, Air Temperature, Tropopause, Precipitable Water, Water Vapor, Cloud Amount/Frequency, Cloud Height, Cloud Top Pressure, Cloud Top Temperature, Reflectance, Emissivity, Sea Surface Temperature, Ozone, Surface Pressure, Cloud Vertical Distribution.

(The Shortname for this product is AIRX3STM).

Quality

The V5 Level 3 gridded products are derived from the Level 2 standard swath products. The Level 2 quality indicators determine which of the Level 2 Standard Product data are combined to create the Level 3 Product. It is important that the user of Level 3 Products become familiar with these quality indicators, and we urge the user to read the documentation describing the AIRS Level 2 Standard Products and the AIRS Level 2 Quality Control and Error Estimation for a description of the quality indicators, how they are set and how to use them.

V5_L2_Quality_Control_and_Error_Estimation.pdf
(http://disc.sci.gsfc.nasa.gov/AIRS/documentation/v5_docs/AIRS_V5_Re...
As a general rule, Level 2 retrieved quantities whose quality indicators are “best” (=0) or “good” (=1) are included in the sums that generate the Level 3 product.
