General Information

Name
IPCC DDC AR4 BCCR-BCM2.0 20C3M run1
Acronym
BCCR_BCM2.0_20C3M_1
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 climate of the 20th Century experiment (20C3M).

These datasets are available in netCDF and GRIB format.

Experiment was initiated from model year 85 (nominal year 1850) of the control simulation. The time varying forcing agents were varied based upon observations and reconstructions for the late 19th and 20th centuries.
Varying forcing agents: CO2,CH4,N2O,CFC11(including other CFCs and HFCs),CFC12 and sulfate aerosols (Boucher data, only direct effect).

Non-varying forcing agents: Background aerosols: black carbon,sea salt,desert dust, stratospheric and tropospheric ozone, solar irradiance (1368 W/m2) and the distribution of land cover types.
No volcanic aerosols. No heat or fresh water adjustments.

For this experiment there is only one run available.
