===Downscaling===
The global mean temperature change from MAGICC, and maps of temperature and precipitation change are used in a pattern scaling, to derive spatially explicit temperature and precipitation changes at one-year time steps to be used in other IMAGE modules (on [[Carbon cycle and natural vegetation]], [[Crop and grass]], [[Water]], [[Nutrient balances]]).

Grid-specific temperature and precipitation changes at the end of the century (2071–2100 compared to 1961–1990) from AR4 [[AOGCM model]] results (Ref database) are linearly interpolated based on the MAGGICs global mean temperature change at a certain time step, and the global mean temperature change corresponding to this map.  For future calculations, the results of AR5 should be used to update the MAGICC parameterisation for all available AOGCMs, and to update the gridded patterns of climate change.
