Abstract :
The Bayesian Algorithm for Microwave Precipitation Retrieval (BAMPR) is a cloud resolving model (CRM)-based retrieval technique for estimating surface rainfall and precipitating cloud profiles by means of microwave radiometric measurements from space. In this paper is illustrated the version of BAMPR tailored for the multi-frequency microwave radiometer aboard of the Tropical Rainfall Measuring Mission (TRMM), called TRMM Microwave Imager (TMI). Since the inversion procedure is based on a cloud-radiation database (CRD) pre-generated by performing radiative transfer calculations on the CRM numerical outputs, the important aspect of CRD representativeness is described. Results of applying BAMPR to a selected event observed by TRMM are finally discussed.
