Downscaling is a tool to link different geographical scales,
IMAGE socio-economic modelling is done on the scale of 26 world regions. However, some applications and users of IMAGE output need more detailed information. For this purpose, tools have been developed to downscale information on population, income, energy use and emissions to a 0.5 x 0.5 grid level (Van Vuuren et al., 2007b) and to 5 x 5 minute grid for population and income. Information from the Earth system is available at 0.5 degree or 5 minute resolution.
