The SRES data sets were published by the IPCC in 2000 and classified into four different scenario families (A1, A2, B1, B2). SRES-A2 storyline describes a very heterogeneous world with the underlying theme
The control integration, in which the atmospheric forcing is kept constant, simulates a period over 300 years in length. Control experiment (CTL): In CTL, greenhouse gases and aerosols are prescribed
Greenhouse gas experiment (GHG) In GHG, the concentrations of the following greenhouse gases are prescribed as a function of time: CO2, CH4, N2O and several industrial gases, i.e., chlorofluorocarbons
Control experiment (CTL) In CTL, greenhouse gases and aerosols are prescribed exactly as in the uncoupled ECHAM-4 model. The concentrations of carbon dioxide, methane and nitrous oxide are fixed at the
The control integration, in which the atmospheric forcing is kept constant, simulates a period over 240 years (1860-2099) in length. Control experiment (CTL): In CTL, greenhouse gases and aerosols are
Here the greenhouse gas forcing is increased gradually to represent the observed changes in forcing due to all the greenhouse gases from 1860 to 1990. From 1990 to 2100 it uses an increase in concentrations
The sulphate aerosol (direct effect) and greenhouse gas experiment (GSD): The forcing includes not only the greenhouse gas forcing described with the "greenhouse run" but also the direct radiative effect
The sulphate aerosol (direct effect), greenhouse gas and ocone experiment (GSDIO): The forcing includes not only the greenhouse gas forcing described with the "greenhouse run" but also the direct radiative
