Short summary

The study provides high-resolution global grids of revised annual coefficients for the Priestley–Taylor and Hargreaves–Samani evapotranspiration methods after calibration based on the ASCE-standardized Penman–Monteith method. Additional analysis was also performed in order to develop respective coefficients for the solar radiation formula of Hargreaves–Samani. The results of the study can be used to improve evapotranspiration assessment for regions with limited climatic data.
