These data are available for users wanting to generate custom Level-2 products using the Collection 2 surface reflectance and surface temperature algorithms. It is not necessary for users to download the atmospheric auxiliary data for use with Collection 2 Level-2 products. 

The USGS creates Network Common Data Form Version 4 (NetCDF4) files that contain the subset of GEOS-5 FP-IT datasets used in ST processing. Each 3-hour global file contains "H" height, "QV" specific humidity, and "T" air temperature values on a grid of 576 longitude, 361 latitude, and 42 pressure levels, for a single 3-hour period. The axis values are recorded in the "lat", "lon", "lev", and "time" datasets, respectively. The new files are in the same format as the original FP-IT files.

Refer to GEOS Systems and GEOS Weather Analysis and Prediction for information about the GEOS-5 FP-IT project. The content and format are described in the File Specification document. (October 2015).
