Datasets description

  This global terrestrial evapotranspiration is derived from the complementary relationship model, with three different approaches to determining the PT-alpha. The forcing includes air temperature and wind speed from ERA5, Relative humidity from 20CR, Rn from multi-source data. It is at 0.5° and has a monthly temporal resolution. The temporal coverage is 1901-2014.
