Process DescriptionCreated from the temperature grids <temp>, <tmax> and <tmin> using a two step procedure:- estimate PET from temperature according to the Hargreaves method;- estimate PET-Penman-Monteith from PET-Hargreaves through regression.Separate regression equations for the relationship between PET-Penman-Monteith and temperature have been established for the climatic zones according to the K?ppen climate classification.For more details is referred to the citation (De Pauw, 2008) for this dataset.
