[ Derived from parent entry - See data hierarchy tab ] Simulation of long-term anthropogenic climate change with the MPI/UW earth system model. The model was driven with emissions corresponding to the SRES A1B scenario with an exponential decay with a time-constant of 150 years after 2100. This simulation has been performed within the DEKLIM-CLIMCYC project. The MPI/UW earthsystem model is build up by the coupled atmosphere (ECHAM3.6, T21)- ocean (LSG2, 64x64) - vegetation (LPJ) - marine biogeochemistry (HAMOCC 3) and interactive ice sheet (SICOPOLIS) models. The latter two models encompass the complete carbon cycle permitting a predictive atmospheric pCO2 simulation. The simulation was run on a NEC-SX6 (hurrikan). A synchronous-asynchronous coupling scheme was applied. Thus, the atmospheric model component was integrated only during synchronous periods. During asynchronous periods fluxes for the other model components were taken from an archive successively build-up from previous synchronous periods.
