Metadata for 'IPCC DDC AR4 GFDL-CM2.0 20C3M run2'

Name
IPCC DDC AR4 GFDL-CM2.0 20C3M run2
Acronym
GFDL_CM2.0_20C3M_2
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 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
GFDL experiment name = CM2Q-d2_1861-2000-AllForc_h2. PCMDI experiment name = 20C3M (run2). Initial conditions for this experiment were taken from 1 January of year 101 of the 1860 control model experiment named CM2Q_Control-1860_d2. Several forcing agents varied during the 140 year duration of the CM2Q-d2_1861-2000-AllForc_h2 experiment in a manner based upon observations and reconstructions for the late 19th and 20th centuries. The time varying forcing agents were atmospheric CO2, CH4, N2O, halons, tropospheric and stratospheric O3, anthropogenic tropospheric sulfates, black and organic carbon, volcanic aerosols, solar irradiance, and the distribution of land cover types. The direct effect of tropospheric aerosols is calculated by the model, but not the indirect effects.
For this experiment there are 3 ensemble runs available.
