Data Distribution Centre (DDC)
The Data Distribution Centre (DDC) provides climate, socio-economic and environmental data, both from the past and also in scenarios projected into the future.
Technical guidelines on the selection and use of different types of data and scenarios in research and assessment are also provided.
The DDC is designed primarily for climate change researchers, but materials contained on the site may also be of interest to educators, governmental and non-governmental organisations, and the general public.
The DDC provides five main types of data and guidance:
- Climate estimates from observations
- Global climate model data, available as at a range of frequencies or as climatologies
- Socio-economic data and scenarios; the DDC provides access to baseline and scenario data related to population, economic development, technology and natural resources for use in climate impact assessments.
- Data and scenarios for other environmental changes; these include data on global mean CO2 concentration, global and regional sea-level rise, regional ground-level ozone concentration, sulphate aerosol concentration and sulphur deposition.
- Linked data resources
The DDC is overseen by the Intergovernmental Panel on Climate Change (IPCC) Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) and jointly managed by the British Atmospheric Data Centre (BADC) in the United Kingdom, the CSU World Data Center Climate (WDCC) in Germany, and the Center for International Earth Science Information Network (CIESIN) at Columbia University, New York, USA. The data are provided by co-operating modelling and analysis centers.
