About the IPCC Data Distribution Centre

Creation of the IPCC Data Distribution Centre

The DDC has been established to facilitate the timely distribution of a consistent set of up-to-date scenarios of changes in climate and related environmental and socio-economic factors for use in climate impacts assessments. The intention is that these new assessments can feed into the review process of the IPCC.

The initiative to establish a DDC grew out of a recommendation by the IPCC Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA). This Task Group was itself formed following a recommendation made at the IPCC Workshop on Regional Climate Change Projections for Impact Assessment (London, 24-26 September 1996).

The establishment of the DDC was approved by the IPCC Bureau at its Thirteenth session (9-11 July 1997) and it was subsequently determined at the XIIIth IPCC Plenary (Maldives, 22-28 September 1997) that the DDC would be a shared operation between the Climatic Research Unit (CRU) in the United Kingdom and the Deutsches Klimarechenzentrum (DKRZ) in Germany. In 2003 a third centre, the Center for International Earth Science Information Network (CIESIN) in the USA, joined the DDC collaboration. From February 1st, 2007 British Atmospheric Data Centre (BADC) has replaced CRU as the United Kingdom partner.

TGICA Mandate and DDC Governance

The conduct of TGICA is governed by its mandate, which can be downloaded here as an Adbobe pdf document. The TGICA has established a set of procedures for managing content on the DDC as described in the DDC Governance document, which can be downloaded here as an Adbobe pdf document.
