Evapotranspiration (ET) plays a critical role in linking the water and energy cycles but is
difficult to estimate at regional and basin scales. In this study, we present a worldwide
evaluation of nine ET products (three diagnostic products, three land surface model (LSM)
simulations and three reanalysis-based products) against reference ET (ET wb) calculated
using the water balance method corrected for the water storage change at an annual time
scale over the period 1983–2006 for 35 global river basins. The results indicated that there …
