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 SRES A1B experiment.
These datasets are available in netCDF and GRIB format.
Experiment was initiated from model year 235 (nominal year 2000)of the climate of the 20th Century experiment (with bcm_experiment_name: PT3). 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.

Project
IPCC Data Distribution Centre : Assessment Report Four data sets (IPCC-DDC_AR4)
The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and
UNEP to assess scientific, technical and socio-economic information, relevant
for the understanding of climate change, its potential impacts and option for adaption
and migration. Projection of future trends for a number of key variables are provided
through this section of the DDC (
http://cera-www.dkrz.de/IPCC_DDC/index.html ).
The SRES scenarios have been constructed to explore future developments in the global
enviromental with special reference to the production of greenhouse gases and aerosol
precursor emission.
A set of four scenario families (A1, A2, B1, B2) have been developed that each of this
storylines describes one possible demographic, polito-economic, societal and
technological future. Model experiments, also using different forcing scenarios,
were calculated at other modeling centres.
The data represent a subset of data sets from the IPCC Model Output Archive at
PCMDI (
http://www-pcmdi.llnl.gov/ipcc/about_ipcc.php).
_
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. SRB1: SRES B1)
- 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_SRB1_1_G_hur850
