Summary: 

Downscaling of climate change models is the procedure of using large-scale climate models to make climate predictions at finer temporal and spatial scales to fit the purpose of local level analysis and planning. This typically involves use of Global Climate Models (GCMs) representing physical processes in the atmosphere, ocean, cryosphere and land surface, simulating the response of the global climate system to increasing greenhouse gas concentrations, using different emissions scenarios. Downscaling tools such as high resolution regional climate models (RCMs) can then be used to simulate the scenarios on a finer spatial scale, using finer level local conditions.
