Simulation of pre-industrial climate using COSMOS-1.2.0
(ECHAM-5.4.01+, echam5/jsbach cosmos-dev Revision 2200 +,
MPIOM-1.3.1 incl. HAMOCC, PRISM-2.5, 09-Apr-2009)
The coupled model was restarted in year 800 after a more than 4000-year spinup phase and was run for 2000 years using the following fixed forcings. Atmospheric CH4 (=650ppb) and N2O (=270ppb) concentrations for year 800 were derived from ice core measurements at Law Dome, Antarctica (MacFarling Meure, C., D. Etheridge, C. Trudinger, P. Steele, R. Langenfelds, T. van Ommen, A. Smith, and J. Elkins (2006), Law Dome CO2, CH4 and N2O ice core records extended to 2000 years BP, Geophys. Res. Lett., 33, L14810, doi:10.1029/2006GL026152).
CFC concentrations were set to zero while pre-industrial climatological values were used for O3 and sulfate. The model was run under perpetual orbital conditions of year 800 (identical to mil0001).
CO2 is interactively transported in the atmosphere and the ocean. The atmospheric concentration was initially set to 278ppm, again derived from the Law Dome ice core for year 800, at the beginning of the spinup run but, at the end of the spinup, had reached a value of about 281ppm which was used at the start of slo0072 (identical to mil0001).
The ocean state at the start of the coupled spinup run was taken from separate, standalone MPI-OM and HAMOCC spinup experiments using Levitus and OMIP forcings (identical to mil0001).
As the boundary conditions are not time dependent, the time access is arbitrary.
The simulation was run on a linux cluster (tornado).
Atmospheric data is stored every 6 hours.
