IPCC DDC AR4 CGCM3.1-T47_(med-res) 20C3M run3

Flato, Gregory M.

Experiment
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 20th Century experiment (20C3M).

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. 20C3M: 20C3M)
- 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_20C3M_1_G_hur850

This integration started at the same point as the preindustrial control run, and spans the period 1850 to 2000. GHG concentrations are prescribed following observations and match the IPCC SRES concentrations at year 1990. The direct aerosol forcing is incorporated via a change in surface albedo which is proportional to the prescribed, time-evolving column burden of sulphate aerosols obtained from O. Boucher, Laboratoire d\'Optique Atmospherique, France.

For this experiment there are 5 ensemble runs available.

Model output data for CMIP3 in higher temporal resolutions and further variables are available in ESGF at https://esgf-node.llnl.gov/search/cmip3/.
