Validation of TRMM radar rainfall data over major climatic regions in Africa

From: Journal of Applied Meteorology | Date: February 1, 2003| Author: | Copyright information

ABSTRACT

The Global Precipitation Climatology Center global-precipitation-analyses rain gauge data have been used to validate the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) data over the major climatic regions in Africa. The threshold-matched precipitation index and the TRMM-and-other-sources "best-estimate" data (3B43) have also been compared with rain gauge data and with the TRMM PR rainfall product. In the 36month climatological assessment of the satellite products at a grid spacing of 1.0 deg, continental Africa has been categorized into five distinct climatic ...
