Similar to the evaluation of the five daily reanalysis precipitation products，the evaluation is also executed at monthly scale.Four statistical indices:ME，BIAS，CC and R2 were selected to evaluate the accuracy of APHRODITE，NCEP-CFSR，CHIRPS，CMA and AgMERRA.All of the selected four evaluation indices are summarized in Table 4.Table 4 shows that although the CC and R2 improved a lot from daily scale to monthly scale，the increases of CC and R2 for NCEP-CFSR were much less than the other four precipitation products.Also NCEP-CFSR shows the lowest correlation coefficient in both sub-basins compared with the other four precipitation products，a contrast to the NCEP-CFSR daily-scale results.From the ME and BIAS values in Table 4，it can be seen that APHRODITE，CHIRPS and AgMERRA tend to overestimate precipitation while NCEP-CFSR and AgMERRA show the opposite results in subbasin11.However，in subbasin46the evaluation with ME and BIAS exhibits different results，with NCEP-CFSR and CHIRPS showing an overestimation trend while the other three products show opposite results.
