Optimization of an Algorithm for the Estimation of Rainfall from the Special Sensor Microwave Imager Data

[摘要] The optimization of an algorithm is presented, for the estimation of rainfall over the oceans. The empirical algorithm previously developed was based on a thorough statistical analysis of SMMR and SSM/I data, as well as on radar data obtained during the GATE experiment. Since some results seemed overestimated, we performed a critical revision of the derivation of the algorithm, and calculated new coefficients. This modified algorithm gave satisfactory results in the comparison between the SSM/I derived rainfall and the corresponding values obtained by radar's in the framework of the GPCP program.
