摘要: Abstract This study evaluates space-based rain estimates from the Tropical Rainfall Measuring Mission (TRMM) satellite using ground-based measurements radar (GR) and tipping-bucket gauges (TG) over TRMM Ground Validation (GV) site at Melbourne, Florida. The products are derived Microwave Imager (TMI), precipitation (PR), combined (COM) algorithms observations both instruments. GV spatiotemporally matched intercompared multiple time scales 12-yr period 1998 to 2009. On monthly yearly scales, TG agree excellently with GR because rates generated data as a constraint on basis. However, large disagreements exist between shorter of their significantly different spatial temporal sampling modes. biases relative for PR TMI generally negative, few e...
