Abstract:
Accurately assessing the temporal and spatial accuracy characteristics of existing multi-source satellite-based precipitation products can lay a solid meteorological data foundation for the efficient development and utilization of water resources in the Yangtze River basin (YRB). The daily precipitation data of 191 meteorological gauges in YRB from 1999 to 2019 and four types of satellite-based products of TRMM(Tropical Rainfall Measuring Mission),CMORPH(CPC MORPHing technique),CHIRPS(Climate Hazards Group Infrared Precipitation with Station data) and PERSIANN_CDR(Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks Climate Data Record)were used.The indicators (e.g.R,ERMS and ENS)were used to evaluate the detection accuracy of four satellite-based precipitation products related to gauge based precipitation at temporal and spatial scales.POD,RFA and TS classification evaluation indicators are used to measure the ability of four satellite-based precipitation products of different magnitudes.
