I am working with the SWY and SDR models and had problems acquiring evapotranspiration (ET0) data. The data suggested by the Invest User Guide (WorldClim) does not address the time scale in which I am working (from 2002 to 2022).
I initially tried MODIS data for evapotranspiration in this period. However, I don’t know if this data can be used, as the ET0 calculation equations are different from the ‘modified Hargreaves’ equation suggested in the user guide.
I would like to know if there is any other source of data with a time scale from the year 2000 onwards that can be used as input data for the models.
Thank you, best regards
