Direct verification was carried out using FLUXNET and other ground observation data. The estimated results were in good agreement with the ground measured data. The daily evapotranspiration verification RMSE was 0.93 mm/d, the error was 0.08 mm/d, and the correlation coefficient was 0.75. This dataset applies cumulative sum to the daily evapotranspiration values estimated by ETMonitor to obtain monthly evapotranspiration, which is converted into latitude and longitude projections for public release.
