Request CMIP5 data sets

You must have an active project or an approved allocation request in order to ask for the addition of a CMIP5 data set to the CMIP Analysis Platform.

Before you submit a request, check here to see if the data set that you need is already available.

If the data set is not there and you meet the criteria described on the home page, use the form below to submit your request.

Fulfilling a small request takes about two weeks. Large requests–those that involve several models and/or high data frequency, for example–take longer.

NCAR staff: The CMIP Analysis Platform data sets are available for your analyses without any action on your part. If you would like to ask for a data set to be added to the repository, contact cislhelp@ucar.edu to request access to the platform before completing the request form.
