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

The primary objective of the 2A21 is to compute the path integrated

Quality A Table structure (called Scan Status) is included in the HDF file,
containing entries on a scan-by-scan basis. These entries include a
geolocation flag and a data quality flag, indicating the percentage of
pixels along each scan with values within a pre-defined range. There are
also various reliability flags and factor.
