In the microwave regime, the relatively low and stable emissivity of the sea surface serves as an excellent background over which brightly emitting hydrometeors can be distinguished. Space/time oceanic rainfall has been estimated from microwave radiometry using a simple radiative transfer model of an atmospheric rain column, a rain rate distribution to account for sampling deficiencies, and an empirical correction of the nonuniformly filled field of view of the microwave sensor. The microwave emission-based brightness temperature histogram (METH) technique has been applied to the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSM/I) to produce over 25 years of monthly oceanic rainfall. The METH technique is described and the retrieved parameters are assessed. The inter-satellite calibration of microwave and DMSP SSM/I sensors provided a climate-scale oceanic rainfall time series capable of examining climate trends and variabilities.
