Model for the Assessment of Greenhouse Gas Induced Climate Change/Scenario Generator

Description:

MAGICC consists of a suite of coupled gas-cycle, climate and ice-melt models integrated into a single software package. The software allows the user to determine changes in greenhouse-gas concentrations, global-mean surface air temperature, and sea level resulting from anthropogenic emissions of greenhouse gases and aerosols.

SCENGEN constructs a range of geographically explicit climate change projections for the globe using the results from MAGICC together with AOGCM climate change information from the Coupled Model Intercomparison Project (CMIP3) archive. Projections of absolute (rather than relative) future climate conditions for any future date covered by the input emissions data can be obtained also. To produce these projections, SCENGEN adds the climate change information to observed baseline climate data (1980-99 means). These results are given as array files on a standard 2.5x2.5 degree latitude/longitude grid and displayed as maps.
