In this study, the biases and uncertainty of TRMM 3B42 estimates are investigated over the Huai-River Basin during the summer season in 2010. TRMM products of 3B42RT, 3B42V6 and 3B42V7 are cross-compared to Chinese Precipitation Analyses Products (CPAP) as the reference. It is found that the distribution of bias is closely depend on the terrain with the dry bias locates at hills/mountains and wet bias lies on the plains area. It is concluded that the bias may be caused by the defect of TRMM algorithm which cannot discern different types of precipitation. 3B42V7 product shows the best improvement in reducing both wet and dry bias; it also appears small uncertainty on summer season precipitation estimate.
