AIRS Monthly Gridded Retrieval Product

AIRX3STM data sample

---

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° grid cells, from -180.0° to +180.0° longitude and from -90.0° to +90.0° 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.
