Global evapotranspiration products from GLEAM (Global Land Evapotranspiration Amsterdam Model) and MOD16 (MODIS Global Evapotranspiration Project) have been widely validated and applied. However, due to insufficient observational data, there is still a lack of products validation in plateau areas. This study took Lake Ranwu, Yamzho YumCo, Nam Co, Siling Co and Taro Co basins as study area, and applied basin water balance, correlation coefficient, relative error, root mean square error and Kling-Gupta coefficient to verify and evaluate the accuracy of GLEAM and MOD16 products in the Qinghai-Tibet Plateau. The results demonstrated that GLEAM products were underestimated in Lake Ranwu, Siling Co and Taro Co basins, slightly overestimated in Yamzho YumCo and Nam Co basins, while MOD16 products were slightly underestimated in Siling Co basin and overestimated in other lake basins. GLEAM and MOD16 products were overestimated in dry year, and underestimated in wet year in the five lake basins. GLEAM products showed high accuracy in Lake Ranwu, Yamzho YumCo and Siling Co basins, while MOD16 products had high accuracy in Nam Co and Taro Co basins. In general, the accuracy of GLEAM products was significantly better than that of MOD16 products in the central and southeastern lake basins of the Qinghai-Tibet Plateau on the annual scale and the multi-year average scale. This results provided an important reference for the selection of evapotranspiration products suitable for the Qinghai-Tibet Plateau.
