Paper Abstract

This paper introduces the present status of TRMM PR vesrion6 standard algorithms and proposes the possible improvements of them in version 7. The present PR standard algorithm system is composed of 1B21, 1C21, 2A21, 2A23, 2A25, 3A25 and 3A26 algorithms. These algorithms are used to analyze more than ten-year TRMM PR data. The algorithm 1B21 calculates PR received power, and 1C21 calculates Z value without rain attenuation correction. The algorithm 2A21 calculates surface reference sigma-zero values and estimates the path-integrated attenuation(PIA) by rain. The algorithm 2A23 detects bright band and classifies the rain type into the stratiform type, convective type and others. The algorithm 2A25 estimates rain rate profiles and Z profiles with rain attenuation correction for each radar beam. The algorithm 3A25 gives monthly statistical values of level 2 products. The algorithm 3A26 calculates monthly averaged rain rates of 5 degree by 5 degree boxes by applying the multiple threshold statistical method.
