Summary

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

The Visible/Infrared Scanner (VIRS) Radiance Gridded Orbital data are a special product derived from the TRMM standard product, VIRS Radiance (1B-01), and mapped to a 0.25 degree x 0.25 degree latitude/longitude grid. The spatial coverage is defined by a 720 km swath bounded by the latitudes 38 degree N and 38 degree S for a single satellite orbit. The parameters included in this data set are the scene radiance data for the five VIRS channels.

Quality For the Level 1B VIRS 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, as well as a data quality flag for each channel, indicating the percentage of pixels along each scan with values within a pre-defined range.
