In order to save developpment and file preparation time, it has
been decided that the output format of the MOTIF
project will follow the output format required for IPCC as closely as
It is expected that the same requirements will be imposed for other projects in the climate models community, and the efforts required to prepare the data for MOTIF will likely have long term payoffs as similar model output is prepared for these other projects.
The following sections give more details about what is required exactly (and why!), how the MOTIF requirements differ from IPCC, and how the use of the CMOR (Climate Model Output Rewriter) library can help you meet the requirements.
