Selection of climate model simulations for the DECCMA project

This report describes the selection of climate model simulations for use in the DEltas, Vulnerability, and Climate Change: Migration as an Adaptation (DECCMA) project. Data from the selected simulations are being used as input for modelling activities assessing the impact of climate change on the Ganges-Brahmaputra-Meghna (GBM), Mahanadi, and Volta deltas. The DECCMA project has chosen to downscale the Coupled Model Intercomparison Project phase 5 -Global Climate Model (CMIP5 GCM) output dynamically, using Regional Climate Model (RCM) simulations. Early in the DECCMA project it was decided to focus only on climate model simulations of the Representative Concentration Pathways RCP8.5 scenario.UK Department for International Development (DFID
