TRMM 3B42: 3-Hourly Precipitation Estimates
The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA) designed to monitor and study tropical rainfall. The 34B2 product contains a gridded, TRMM-adjusted, merged infrared precipitation (mm/hr) and RMS precipitation-error estimate, with a 3-hour temporal resolution and a 0.25 degree spatial resolution. See the [algorithm description](https://trmm.gsfc.nasa.gov/3b42.html) and the [file specification](https://storm.pps.eosdi
