Summary
Abstract: The primary objective of algorithm 3A25 is to compute various rainfall statistics over a month from the level 2 PR products. The statistics are derived at two spatial resolutions: (1) a standard space scale of 5 degrees by 5 degrees (latitude x longitude) cells and (2) a high resolution subset of 0.5 degree x 0.5 degree cells.

The output variables include rainfall rate (mm/hour) profile at 2, 4, ... View entire text

Quality Missing data scans are checked by monitoring the Scan Status contained in the TRMM 1C-21 product. Scan Status is a Table structure 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. If Scan Status indicates a missing scan, then no processing is done for that scan for the 3A25 product. However, checks for individual missing variables are not done explicitly.
