For the climate simulations, daily precipitation and temperatures (maximum and minimum temperatures) derived from the CMIP5 and CMIP6 archives (21 GCMs from CMIP5 and 21 GCMs from CMIP6) were selected (Table 1). The CMIP5 and CMIP6 outputs were downloaded from the Earth System Grid Federation. Even though they are not exactly from the same climate centers, most of them are from the same climate centers with advanced versions in CMIP6. These 42 GCMs provide the climate variables under the historical forcing for the reference period (1976–2005), RCP8.5 (CMIP5) and SSP5-85 (CMIP6) forcing for the 2071–2100 period. The use of a large number of GCM simulations is to adequately cover the inter-model variability.
