AIRS/Aqua Level 3 8-day standard physical retrieval (AIRS+AMSU+HSB) V005 (AIRH3ST8) at GES DISCEntry ID: GES_DISC_AIRH3ST8_V005
Abstract: This product is similar to AIRX3ST8. However, it contains science retrievals that use the Humidity Sounder for Brazil (HSB). Because the HSB instrument lived only from September 2002 through January 2003 when it terminally failed, the data set covers these five months only.
The AIRS Level 3 8-Day Gridded Retrieval Product contains standard retrieval means, ... standard deviations and input counts. Each file covers an 8-day period, or one-half of the Aqua orbit repeat cycle. 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 x 1 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 thermodynamic parameters are: Skin Temperature (land and sea surface), Air Temperature at the surface, Profiles of Air Temperature and Water Vapor, Tropopause Characteristics, Column Precipitable Water, Cloud Amount/Frequency, Cloud Height, Cloud Top Pressure, Cloud Top Temperature, Reflectance, Emissivity, Surface Pressure, Cloud Vertical Distribution.
The trace gases parameters are: Total Amounts and Vertical Profiles of Carbon Monoxide, Methane, and Ozone.
The actual names of the variables in the data files should be inferred from the Processing File Description document.
(The Shortname for this product is AIRH3ST8).

ISO Topic Category
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.
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.
