A review of downscaling methods for climate change impacts on water resources

Measuring the impact of climate change on water resources is commonly based on downscaled simulations from global climate models (GCMs). The downscaling of GCMs is used to improve representation of climate data over a regional part which can be produced either by using a regional climate model (RCM)...
