Dear CMIP5 Modelling Teams,

The questionnaire to collect metadata about your model setup for CMIP5 is ready for you to use at  http://q.cmip5.ceda.ac.uk/. The questionnaire will provide vital information to help users of the CMIP5 database understand why different models respond in unique ways to the various elements of the CMIP5 experiment protocol. Completion of the questionnaire is a necessary step towards the publication of your data. The questionnaire will ask you to describe core information about your models and it also gives you the freedom to share further model characteristics as you see fit. Once all the core information has been described you will be able to submit your questionnaire entries to CMIP5. Although the questionnaire requires core information, the value of your information will depend on you, since the quality (and extent beyond the core) is your responsibility.  Completing the CMIP5 questionnaire is a demanding task and support will be provided to you by the Metafor team who designed and developed the questionnaire under the guidance of the CMIP panel.

Instructions for accessing modelling centre pages of the questionnaire can be found at  http://metafortrac.badc.rl.ac.uk/trac/wiki/CMIP5/QuestionnaireAccess/
Further information about the questionnaire can be found in the open letter to our users  http://metaforclimate.eu/trac/wiki/CMIP5/QuestionnaireOpenLetter
