Spatio-temporal analysis of the accuracy of Tropical Multisatellite Precipitation Analysis 3B42 precipitation data in mid-high latitudes of China

The main objective of our study is to assess the accuracy of TMPA 3B42 V7 (hereinafter referred to as TMPA V7) data over the mid-high latitude region of China. This region is situated beyond the nominal coverage (38 NS) of the TRMM Microwave Imager (TMI) and Precipitation Radar (PR). Obviously, large bias and error would exist over this region. We provide a systematic evaluation of TMPA V7 in terms of precipitation amounts and occurrency of precipitation events.
