%X Evaporation (ET) is an important component of the water cycle and serves as a link between the global water cycle, energy cycle, and carbon cycle. Therefore, precise quantification of evapotranspiration is crucial for understanding various Earth system processes and subsequent social applications. The existing evapotranspiration retrieval methods either have limited spatiotemporal coverage or are largely influenced by input data selection, simplified model physics, or a combination of both. Here, we have developed a water balance based evapotranspiration dataset (ET-WB) using an independent conservation of mass method for global land and selected 168 major watersheds. We utilized multi-source datasets from satellite products, in-situ measurements, reanalysis, and hydrological simulations (23 precipitation datasets, 29 runoff datasets, and 7 reserve change datasets) to generate 4669 probability based unique combinations of evapotranspiration datasets between May 2002 and December 2021.
