The spatial error structure of surface precipitation derived from the latest version 7 Tropical Rainfall Measuring Mission (TRMM) Multi satellite Precipitation Analysis (TMPA) algorithms are systematically studied by comparing with the daily China precipitation analysis product (CPAP) from September 2008 to August 2012. The TMPA products include the real time product 3B42RT, the research product 3B42 (3B42V7). In terms of four year mean daily precipitation the 3B42V7 products are highly correlated with CPAP with correlation coefficient (CC) being about 0.94, relative bias (RB) about -0.11% and the root mean square error (RMSE) about 0.53 mm·d-1. The 3B42RT product has lower CC about 0.75 and higher relative bias (RB) about 39.30% and RMSE about 1.25 mm·d-1. The 3B42RT product overestimated the rainfall in the west of China with RB about 116.60 % for the whole year (104.52%、 105.73%、117.64% and 326.60% respectively for spring, summer, autumn and winter). The relative error of 3B42V7 product is only 0.82 % (2.25%, 1.24%, -5.27%, -24.64% for spring, summer, autumn and winter, respectively).
