Project: IPCC Data Distribution Centre : Third Assessment Report data sets
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.

Summary: The SRES data sets were published by the IPCC in 2000 and classified
into four different scenario families (A1, A2, B1, B2).
SRES_B2 storyline describes a world in which the emphasis is on
local solutions to economic, social and enviromental sustainability.
The global population is increasing at a lower rate than A2. It has
an intermediate level of economic development and a less rapid and
more diverse technological change than in A1 and B1.
The Hadley Centre Circulation Model is a 3-dim AOGCM described
by (Gordon et al.,2000 and Pope et al.,2000).
The atmospheric component has a 19 levels horizontal resolution,
comparable with spectral resolution of T42, while the ocean
component has a 20 levels resolution.

The changes of anthropogenic emissions of CO2, CH4, N2O and sulphur
dioxide are prescribed according to the above mentioned scenario.
