The evaluation statistics for monthly precipitation are presented in Table 2.TRMM and CHIRPS estimates had high correlation coefficients with gauge observation of0.862 and 0.820,respectively.The BIAS and ME of TRMM and CHIRPS estimates were all relatively low,and the MAE were both close to 60 mm.These results indicated that TRMM and CHIRPS estimates coincided well with in-situ observation in the study area.The ME results indicated that the average underestimation for TRMM estimates was about–2.4 mm/mon,while CHIRPS estimates underestimated by about–11.3 mm/mon,showing the underestimation for TRMM estimates was smaller than that of CHIRPS estimates.On the whole,TRMM estimates had higher r and lower BIAS,ME,and MAE,illustrating that TRMM estimates could better represent precipitation distribution than CHIRPS estimates.
