The SREC Dataset was published by the IPCC in 2000 and classified into four different scenario families (A1,A2,B1,B2). The B2 storyline describes a world in which the emphasis is on local solutions to economic, social, and environmental sustainability. It is a world with continuously increasing global population, at a rate lower than in A2, intermediate levels of economic development, and less rapid and more diverse technological change than in the B1 and A1 storylines. While the scenario is also oriented towards environmental protection and social equity, it focuses on local and regional levels [www.ipcc.ch]. The concentrations of GHG and sulphur emission are prescribed according to the IPCC pecial Report on Emissions Scenarios (SRES). The model was forced with SST and sea ice coverage taken from the coupled ECHAM4/OPYC3 GSDIO run (from 1990 till 2100). The radiative forcing includes the greenhouse gas forcing, the direct radiative effect and the first indirect effect (cloud albedo effect) of sulphate aerosol concentrations. The troposheric ozone distribution is allowed to change as a result of prescribed anthropogenic emissions of precursor gases. Model year 12 corresponds to real time year 2070 (first 11 years were spinup).
