Name
IPCC DDC AR4 CGCM3.1-T47_(med-res) PICNTRL run1
Acronym
CGCM3.1_T47_PICNTRL_1
Project(s)
IPCC-DDC_AR4 (IPCC Data Distribution Centre : Assessment Report Four data sets)
Summary
These data represent monthly averaged values of selected variables for the Data
Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC).
(see also http://www.ipcc-data.org/)
The model output prepared for IPCC Fourth Assessment climate of the Pre-industrial
control experiment (picntrl).
These datasets are available in netCDF and GRIB format.
A 50-year integration was conducted using 1985 GHG concentrations and restoring to
climatological SST, SSS, and sea-ice extent in order to estimate annual mean heat and freshwater
flux adjustments. This was followed by a 200-year integration with preindustrial GHG concentrations
to allow the model to approximately equilibrate to a preindustrial climate. The end of this
integration served as the initial condition for the preindustrial control integration,
representing conditions at year 1850. The preindustrial GHG concentrations were taken
to be: CO2=288ppm; CH4=792ppb; N2O=275.5ppb; CFC11=CFC12=0.
For this experiment there is only one run available.
