Technical Guidelines, Fact Sheets and other Supporting Material

Several documents providing technical guidelines(1), fact sheets(2) or other summarising information held on the DDC are downloadable from this site. The process for developing technical guidelines is described here and fact sheets here. They constitute IPCC "Supporting Material"(3) and have been prepared at the request of the Task Group on Data and Scenario Support for Impacts and Climate Analysis (TGICA). Note that the documents listed here have not been subject to the formal intergovernmental IPCC review process.

TGICA has developed a general guideline on the use of scenario data, which has three main objectives:

  1. To introduce and describe the information and analytical tools being provided by the Data Distribution Centre;
  2. To offer guidance on how to interpret the baseline and scenario data held by the DDC and elsewhere, in order to facilitate the informed selection and use of data in climate change vulnerability, impact and adaptation assessments;
  3. To highlight and illustrate the key steps and procedures that are commonly required in applying baseline and scenario data in vulnerability, impact and adaptation assessments.

More detailed technical guidelines relate to issues such as the development and application of data and scenarios held on the DDC and elsewhere for use in vulnerability, impacts and adaptation assessments (see schematic diagram).

It is strongly recommended that you familiarise yourself with the appropriate guidelines before downloading data from the DDC.
