This study cross-validates the radar reflectivity Z, rainfall drop size distribution parameter (median volume diameter, Do ) and rate R estimated from Tropical Rainfall Measuring Mission (TRMM) satellite Precipitation Radar (PR), a combined PR TRMM Microwave Imager (TMI) algorithm (COM) C-band dual-polarised ground-radar (GR) for overpasses during passage of tropical cyclone (TC) non-TC events over Darwin, Australia. Two overpass TC Carlos eleven are used in this GR is taken as reference. It shown that correspondence dependent on precipitation type whereby with more (less) stratiform usually have positive (negative) bias whereas generally but small (large). The COM estimates similar to it has smaller most greater events. suggests combining TMI adjusts towards "correct" direction if Moreover, association between two events, which highly nature, observed (there no significant difference) differs largely majority convective
