Instructions for Access to the CMIP5 Questionnaire

We have restricted access to the CMIP5 questionnaire. The Test and Example centres are freely accessible but only those users who have an OpenID issued by an ESG Federation OpenID provider can request access to individual modelling centre pages. The registration and authorisation procedure is listed below:

  1. Get an OpenID If you do not have an ESG Federation OpenID you can obtain one by registering with the BADC.
    To do this visit and follow the "Register as a new user" button.
  1. Request access to a modelling centre Email cmip5qhelp at to request access to a modelling centre. Please state your name, OpenID URL, and the modelling centre you want to access. We will then confirm your request with the contact at your modelling centre.
  1. cmip5q mailing list Please join the  cmip5q mailing list. The cmip5q mailing list will be used to send messages from the cmip5q team to our users. You can also use the mailing list to share day to day questionnaire queries at cmip5q at Alternatively you can raise queries directly with the support team at cmip5qhelp at

If you wish to change to a new OpenID, for example if you've had an OpenID with the BADC but now you wish to use an OpenID from your home ESG site, you will need to re-apply for access with the new OpenID URL (step 2).

Test and Example Centres

We have created a Test centre so that you can play about with the questionnaire before entering information for real in your own modelling centre. The Test centre will be cleared when we make updates to the questionnaire. The Example centre will contain an example of elements of the questionnaire (kindly provided by the UK Met Office). It's always easier to do something when you've seen how someone else did it but... do not edit the example centre!
