Who runs the DDC?

The DDC is a shared operation of the British Atmospheric Data Centre (BADC) in the United Kingdom; the World Data Center Climate at the Max-Planck-Institute for Meteorology (WDCC / MPI-M) in Hamburg, Germany; and the Socioeconomic Data and Applications Center (SEDAC) operated by the Center for International Earth Science Information Network (CIESIN) at Columbia University, New York, USA. Each of these institutions has voluntarily taken on responsibility for managing access to a subset of the data and information provided by the DDC.

The funding for the DDC has been provided by the German Government through the Federal Ministry of Education and Research (BMBF); by the UK Government through the Department of Energy and Climate Change (DECC); and by the US Government through National Aeronautics and Space Administration (NASA).

The DDC is advised and guided by the Task Group on Data Support for Climate Change Assessments (TG-DATA) (formely the Task Group on Data and Scenario Support for Impact and Climate Analysis - TGICA). Both the DDC and the TG-DATA are supported by the IPCC Technical Support Units of Working Group I, Working Group II, and Working group III, through whom they are accountable to the IPCC. The contact details of the relevant personnel are as follows:

Guidance Material

The preparation of the guidance material and documentation for the scenarios will be coordinated by Dr.Timothy Carter of the Finnish Environment Institute, Helsinki, in close co-operation with the DDC. It will include descriptions of the GCM experiments, discussion of the uncertainties of climate scenarios, guidance on their application in impacts studies, and suggestions on the reporting of research results. The procedures for producing full length guidance documents and brief factsheets are given here: guidelines publication procedure and factsheet publication procedure.
