The climate models comparison projects have to deal with a growing
number of files that have to be checked, stored... and
The only way to get any of this done in a reasonable amount of time and make sure the data can actually be used during the course of the project (and hopefully later), is to use standards both for the data files and the metadata associated with the files (and usually included in the files).
The MOTIF project requires therefore that the participants prepare their data files so that they meet the following constraints (regardless of the way their models produce and store their results).
More precise details about the variables and their associated
metadata can be found in the IPCC
requirements and the MOTIF adaptation pages.
Although it is entirely possible to create output data file that meet ALL the mentioned constraints from scratch, we strongly suggest that you create the files you will submit to the database with the CMOR library. This library has been specically developped to help you meet the requirements of the xMIP Model Intercomparison Projects.
