Reference evapotranspiration estimation using reanalysis and WaPOR products in dryland Croplands.

ABSTRACT: Accurate estimation of the reference evapotranspiration (ET_o) is crucial for determining crop water requirements. However, the lack of appropriate weather stations representing croplands, particularly in drylands, may adversely influence the accuracy of ET_o estimates. To overcome this issue, a promising approach is to use meteorological stations in cropland areas to collect weather data that are representative of actual conditions. However, the number of agrometeorological stations in these areas is limited. Therefore, this study aims to assess the effectiveness of three datasets, including ERA5 and ERA5-Land, and WaPOR (Water Productivity Open-access portal), for estimating ET_o in cropland areas on a basin scale. The land use/land cover (LULC) of the Europ
