The IPCC Data Distribution Centre What data do the DDC have?

The DDC distributes a number of datasets that are commonly used in the construction and application of climate change scenarios for climate change impacts assessments. These datasets are available to registered users. The intention is to provide a common set of scenario data for use in climate impacts research that may get reported in the Third Assessment Report of the IPCC. These datasets are described in the following pages (see list left) and pointers to outside sites are made where more detailed, or complementary, data may be found. Explanations and illustrations of how these various datasets can be combined to construct a climate change scenario and how such scenarios can be applied in an impacts study are found on the DDC User Support pages. It is possible to view some of these datasets (e.g. observed climate and GCM scenarios) using the DDC Data Visualisation software. You can download many of these data from the DDC web site (DDC Data Download). If users wish to access the full GCM monthly datasets from which the scenarios described here are derived they are directed to the DDC GCM Archive at DKRZ, Hamburg.
