General Information

Name
IPCC DDC AR4 CGCM3.1-T47_(med-res) COMMIT run2
Acronym
CGCM3.1_T47_COMMIT_2
Project
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 committed climate change experiment (COMMIT).

These datasets are available in netCDF and GRIB format.
The dataset names are composed of
- centre/model acronym (e.g. MPEH5: Max-Planck-Institute/Echam5)
- scenario acronym (e.g. COMMIT: COMMIT)
- run number (e.g. 1: run 1)
- format identifier (e.g. N: netCDF, G: GRIB)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: MPEH5_COMMIT_1_G_hur850

This model runs continues from the end of the 20th century simulation with aerosol loadings held constant at their year 2000 values, and GHG concentrations fixed at: CO2=367ppm, CH4=1760ppb, N2O=316ppb, CFC11=267pptr, CFC12=535pptr

For this experiment there are 5 ensemble runs available.
