The Precipitation Radar(PR) onboard TRMM is the first spaceborne rain in the world, and was developed by NASDA in cooperation with Communications Research Laboratory(CRL).
Major objectives of PR are (1) to provide 3-dimensional rainfall structure, (2)to achieve quantitative rainfall measurement over land as well as over ocean, and (3) to improve the accuracy of TRMM Microwave Imager (TMI) measurement by providing the rain structure information.
