User Support

The DDC has been established by the IPCC to provide a common and easily accessible set of information relating to climate change scenarios for impacts and adaptation assessments. As well as providing direct access to GCM data through the DDC GCM Data Archive, the DDC also provides users with access to a variety of other scenario information and descriptions of these various datasets and how they can be used in scenario construction and impacts assessment.

Users often have questions about what different scenario datasets represent and how they can be used in scenario construction and application. We have provided answers to a set of the most Frequently Asked Questions (FAQs). Although these answers cannot be exhaustive they provide some assistance to users who may be new to climate scenario issues. A more structured guide to the DDC scenarios is provided in the DDC Guidelines Section.

Finally, if you have any questions about the DDC, find errors on the site, or have general questions about climate scenarios that we can add to our FAQs, then please contact the helpdesk
