Direct Statistical Validation

GPM flying over Earth with a data swath visualized.
Friday, February 11, 2011
A GPM Ground Validation prototype is currently underway to compare TRMM satellite data to similar measurements from the national network of operational weather radars. The goal of the Validation Network is to identify and resolve significant discrepancies between the US national network of ground radar observations and satellite observations. The validation network prototype matches-up TRMM Precipitation Radar (PR, see below image) and quality-controlled NEXRAD reflectivity data (right) for 21 ground radar sites in the Southeastern United States. Conceptually, the Validation Network also...

TRMM Instruments

Engineers at Goddard Space Flight Center constructing the TRMM satellite assembl
Monday, January 31, 2011
The Tropical Rainfall Measuring Mission is the first Earth Science mission dedicated to studying tropical and subtropical rainfall: precipitation that falls within 35 degrees north and 35 degrees south of the equator. Tropical rainfall comprises more than two-thirds of the world's total. The satellite uses several instruments to detect rainfall including radar, microwave imaging, and lightning sensors. Flying at a low orbital altitude of 240 miles (400 kilometers) TRMM's data collection of tropical precipitation helps improve our understanding about climate and weather. The Japanese space...
