Aridity index (P/Pet) derived from IDRISI file with continuous data, reclassified into 5 classes (+ water bodies). The IDRISI file was received by IIASA on February 2003.

This raster dataset provides a representation of the change in Annual Evapotranspiration in the Middle East and North Africa Region. Bias-corrected Regional Climate Models (RCM) results serve as inputs for the generation of the Regional Hydrological Model (RHM) ensemble using open-source hydrological model HYPE (Hydrological Predictions for the Environment). The RHM is applied to assess hydrological change using future climate projections and can accommodate large datasets spanning timescales exceeding 100 years. The RHM ensemble adopts the time periods used by the Intergovernmental Panel for Climate Change (IPCC) and other regional climate modelling experiments. It runs climate simulations based on three future time periods that are compared with a historical reference period. Available at 0,19 degree (approx. 21km) pixel resolution, for future time periods; Near, Mid and End-century, the raster grids are generated for moderate and high representative concentration pathways (RCPs), climate change scenarios developed by the IPCC for informing global and regional climate modelling work (RCP4.5 and RCP8.5). The adopted time periods are: Near-Century (2016-2035); Mid-Century (2046-2065); End-Century (2081-2100).
