Then a water deficit dataset was produced by subtracting these two datasets. Later, using R programming languages SPEI package, created by Santiago Beguería and Sergio M. Vicente-Serrano, the SPEI values were estimated for forty-eight different timescales. Finally, the dataset was validated using Climate Research Unit’s dataset, soil moisture dataset and Normalized Difference Vegetation Index dataset.","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}
