  • RICCAR, MENA Region - R20 - Seasonal Count of 20 mm precipitation days (GCM, 1951 to 2100) This raster dataset provides a representation of the heavy precipitation index Seasonal R20 - seasonal count of 20mm precipitation days - number of days when daily precipitation ≥ 20mm - for the Middle East and North Africa Region, 1951-2100 period. The climate change projections use global climate models/global circulation models (GCMs). These are numerical models that combine physical processes on the land surface and in the ocean, atmosphere and cryosphere to simulate the response of the global climate system to increasing greenhouse-gas concentrations. The grids are provided at 50km pixel resolution, for three of the four representative concentration pathways (RCPs) developed by IPCC for informing global and regional climate modelling work namely, low, moderate and high scenarios (RCP2.6 /4.5 /8.5) and generated using GCMs: - CNRM-CM5 System Model; - EC-EARTH System Model; - NOAA-GFDL-GFDL-ESM2M System Model. The seasons are defined as: 1. December-January-February 2. March-April-May 3. June-July-August 4. September-October-November
