Global TRMM Rainmap 2004

Visualizations by Lori Perkins Released on September 30, 2007
This is a three-hour global rainmap from January 1, 2005 through December 31, 2004, as compiled by the TRMM satellite's Multi-satellite Precipation Analysis. The TRMM Multi-satellite Precipitation Analysis produces three hourly rain rates at 0.250 latitude by 0.250 longitude grid covering 500S to 500N. The input data for this merged product include a merged intercalibrated microwave-only product (3B40RT) and an Infrared rain product that is calibrated using microwave rain rates (3B41RT). Currently, 3B40RT is generated using rain rate estimates from microwave measurements from the TRMM sensors and the Special Sensor Microwave Imagers on board the DMSP satellites using the Goddard Profiling Algorithm (GPROF). 3B41RT is based on infrared measurements from geostationary satellites that are calibrated using microwave rain estimates. The 3B42RT estimate consists of the merged microwave estimate within the 3 hourly 0.25 degree space/time grid when available, and the calibrated IR rain rates otherwise.

Typhoon Dianmu (Helen) intensified from a 70 kt/80 mph typhoon to a 155 kt/180 mph super typhoon on June 17, 2004. It is one of only nine typhoons since 1990 to reach that intensity.
