Summary
The SRES data sets were published by the IPCC in 2000 and classified
into four different scenario families (A1, A2, B1, B2).
SRES_A2 storyline describes a very heterogeneous world
with the underlying theme of self-reliance and preservation
of local identities. It results in this scenario a continous
increasing population together with a slower economic growth
and technological change.
The climate system model (CSM) is based on a framework that
divides the complete climate system into component models
connected by a coupler. Individual components are: ocean,
atmosphere, land and sea-ice.
NCAR-CSM (
http://www.ccsm.ucar.edu/models/ ).
The changes of anthropogenic emissions of CO2, CH4, N2O and
sulphur dioxide are prescribed according to the above
mentioned scenario.

IPCC Data Distribution Centre : Third Assessment Report data sets (IPCC-DDC_TAR)
The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO und 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://www.mad.zmaw.de/IPCC_DDC/html/ddc_gcmdata.html).
This information contained in either IS92 emission scenarios (IPCC 1992), the Special
Report on Emission Scenarios (IPCC 2000, SRES) or published model studies using data from
these scenarios.
Six alternative IPCC scenarios (IS92a to f) were published in the 1992 Supplementary Report
to the IPCC Assessment. These scenarios embodied a wide array of assumption affecting how
future greenhouse gas emissions might evolve in the absence of climate policies beyond
those already adoped.
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.
