Summary
Abstract: The Tropical Rainfall Measuring Mission (TRMM) http://disc.gsfc.nasa.gov/precipitation/trmm_instr.shtml is a joint U.S.-Japan satellite mission to monitor tropical and subtropical precipitation and to estimate its associated latent heating.

The Level 1B product file (1B11) contains calibrated brightness temperatures and auxiliary geolocation information for each pixel in the scan. The structure ... View entire text

Project
Quality For the Level 1B TMI product, a Table structure (called Scan Status) has been included in the HDF file, containing entries on a scan-by-scan basis. These entries include a geolocation quality flag and a data quality flag for each channel, indicating the percentage of pixels along each scan with values within a pre-defined range.
