Conditions of Data Access and Use

• These data are for use in research projects only. A 'research project' is any project carried out by an individual or organized by a university, a scientific institute, or similar organization (private or public) for non-commercial research purposes only. Results based on these data must be submitted for publication in the open literature without any delay linked to commercial objectives.

• In first making reference to the data obtained from the CMIP3 archive, please include the phrase "the World Climate Research Program's (WCRP's) Coupled Model Intercomparison Project phase 3 (CMIP3) multi-model dataset". Subsequent references within the same publication might refer to the data with terms such as "CMIP3 data", "the CMIP3 multi-model dataset", "the CMIP3 archive", or the "CMIP3 dataset".

• Whenever you publish research based on model output from the CMIP3 database, you should include the following acknowledgement:

  "We acknowledge the modeling groups for making their model output available for analysis, the Program for Climate Model Diagnosis and Intercomparison (PCMDI) for collecting and archiving this data, and the WCRP's Working Group on Coupled Modelling (WGCM) for organizing the model data analysis activity. The WCRP CMIP3 multi-model dataset is supported by the Office of Science, U.S. Department of Energy."

  [Note that the acronyms, WCRP and CMIP3, should have already appeared in the main text of your article, where they were presumably defined.]
