摘要

•Error estimation and data fusion of gridded precipitation by TC and MTC were studied.•MTC produces more consistent error estimation results with gauge data than TC.•TC-based methods are effective in data fusion and is comparable with BMA and RF-MEP.•Zero rainfall replacement has an effect on error estimation but not on data fusion.
