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

_
The model output prepared for IPCC Fourth Assessment climate of the Pre-industrial
control experiment (picntrl).
_
These datasets are available in netCDF and GRIB format.
_
Spinup: Same as 20C3M (realisation 1). GHGs fixed at 1860 values (CO2 = 286.20 ppm, CH4 = 805.60 ppb,
N2O = 76.69 ppb, equi. CFC11 = 12.48 ppb), sulfate aerosol emissions fixed at 1860 values ,
solar constant of 1365 W/m^2.
_
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
