Convert TRMM product 3B42RT to ASCII Grid ESRI
The “GH2MF2 – Association for a Participated Global Hydrological Monitoring and Flood Forecasting System” has done a free software to convert the binary files (version V7 ) of the TRMM product 3B42RT (3B42RT.2017010100.7.bin.gz) into ASCII Grid format of ESRI. The original data can be downloaded via FTP at the following NASA link:

The Tropical Rainfall Measuring Mission (TRMM) is a joint space mission between NASA and Japan’s National Space Development Agency designed to monitor and study tropical and subtropical precipitation and the associated release of energy. The mission uses 5 instruments: Precipitation Radar (PR), TRMM Microwave Imager (TMI), Visible Infrared Scanner (VIRS), Clouds & Earths Radiant Energy System (CERES) and Lightning Imaging Sensor (LSI). The TMI and PR are the main instruments used for precipitation. These instruments are used in an algorithm that forms the TRMM Combined Instrument (TCI) calibration data set (TRMM 2B31) for the TRMM Multi-satellite Precipitation Analysis (TMPA), whose TMPA 3B43 monthly precipitation averages and TMPA 3B42 daily and sub-daily (3hr) averages are probably the most relevant TRMM-related products for climate research. 3B42 and 3B43 are available in 0.25° spatial resolution, covering 50°N to 50°S for 1998-present (Near Real Time).
