Abstract:
This document provides basic information on 3B42, TRMM and Other Satellites Precipitation Product.The TRMM Multi-Satellite Precipitation Analysis (TMPA; computed at fine intervals as 3B-42) intercalibrates (to 2B31) and combines 2A-12, SSMI, AMSR and AMSU precipitation estimates (referred to as HQ). IR estimates from geostationary IR observations are made by calibrating the IR brightness temperatures to the HQ estimates. The 3B-42 estimates consist of the HQ where available and IR otherwise, all scaled to match the monthly satellite/rain gauge analyses in 3B-43.The output is precipitation (units: mm/hr) for 0.25x0.25 degree grid boxes on the latitude band 50 ° N-S every 3 hours. For more details of the algorithm, go to http://trmm.gsfc.nasa.gov/3b42.html The daily accumulated (beginning at 00Z and ending at 21Z; unit: mm) rainfall product is derived from this 3-hourly product. The data are stored in flat binary. The file size is about 2.25 MB (uncompressed).

Attribute_Accuracy:
Attribute_Accuracy_Report:
Random error estimates are provided for each 0.25 x 0.25 degree box. The quality of the 3B42 product is highly sensitive to the quality of the input data: TMI (product 2A12), and TRMM Combined Instrument (TCI) (product 3B31), SSMI, AMSR, AMSU precipitation estimates and IR estimates. If the quality of the input data is less than anticipated, then the quality of 3B42 will also be less.
