Title
Recent Advances Of The Trmm Pr Beam-Mismatch Correction After The Orbit Boost
Abstract
The Tropical Rainfall Measuring Mission (TRMM) satellite was boosted from 350 km to 402.5 km to conserve its fuel keeping the altitude. As a result, the quality of the Precipitation Radar (PR) data slightly changed and, a mismatch of PR's beam between the transmission and reception antennas happened. Although latest version (V7) of PR's level-l algorithm is corrected by a method, some systematic error of the beam-mismatch correction is found as the left-right asymmetric bias for PR's rain estimates sorted by its scan angle. The current study is conducted to advance the accuracy of the beam-mismatch correction and evaluate its improvement. The current method of the beam-mismatch correction works over the oceans and land, and its improvement is evaluated as about 96 (73) % mitigating the asymmetric bias for PR's rain estimates over the oceans (land) comparing to the V7 product.
