Simulation of pre-industrial climate using COSMOS-1.0.0 (ECHAM-5.3.02p2, MPIOM-1.2.3p2, PRISM-2.5, 23-NOV-2006). Restartdata are taken from IPCC-Control experiment 12520_E20 (EH5-T63L31_OM-GR1.5L40_CTL), modelyear 2650 (atmosphere) or 673 (ocean). Internal date set to 07991231. Concentrations of well mixed greenhouse gases (CO2, CH4, N2O) are prescribed for the year 1860 (as in IPCC-experiment 12520_E20: co2vmr = 286.2E-06; ch4vmr = 805.6E-09; n2ovmr = 276.7E-09_dp). As the boundary conditions are not time dependent, the time access is arbitrary. The simulation was run on a NEC-SX6 (hurrikan). Atmospheric data is stored every 6 hours. The simulation was performed within the project RiftLink (www.riftlink.de).
