7. DATASET OVERVIEW

7.1 Abstract

The Precipitation Radar (PR) onboard TRMM is the first spaceborne rain radar in the world, and is developed by JAXA in cooperation with

NICT. Major objectives of PR are;(1) to provide 3 dimensional rainfall structure, (2) to achieve quantitative rainfall measurement over land as well as the oceans, and

(3) to improve the accuracy of TRMM Microwave Imager (TMI) measurement by providing the rain structure information.
