Model Intercomparison Projects (MIPs)

MIPs Overview

Model Intercomparison Projects (MIPs) address specific science questions across the climate and earth science communities. CMIP first endorsed MIPs during its sixth phase to build on the DECK and CMIP historical simulations and to fill the scientific gaps of the previous CMIP phases. The DECK and CMIP historical simulations, together with the use of CMIP data standards, will be the entry cards for models participating in CMIP. Participation in MIPs by individual modelling groups is at their own discretion and depends on their scientific interests and priorities. 

Registered MIPs

You can view all the currently registered MIPs below. Click on the MIP to read more information. To view the MIPs in a new window, or to view in full screen, follow this link.

There is no deadline for registration but early engagement will ensure your MIP information is available and you will be kept informed of the latest MIP-relevant developments in planning this phase of CMIP.

MIP registration information can be found at the bottom of this page under ‘Information for MIP conveners’.

Information for MIP conveners

CMIP is evolving, as is the way we are keeping track of activities across the community. In order to reduce duplication of effort across MIPs and modelling centres and to foster collaboration, the CMIP Panel have launched a MIP registration form, and new MIP best practice guidance.

MIP Best Practice Guidance

CMIP’s long experience in coordinating model intercomparisons has helped identify a set of practices that allow broad participation and efficient use of resources. These are summarised in the MIP Best Practice Guidance document, which can be found here.

The document includes guidance on MIP development, design, and documentation.  There is also helpful information given for MIPs who wish to take advantage of the data standards and infrastructure that support CMIP.

MIP Registration

We encourage all ongoing and new MIPs (CMIP6-endorsed MIPs and others) to register. This will act as a source of information for CMIP governance to consider when discussing the future CMIP design, as well as information for the climate science community on the activities going on globally. Please note the CMIP Panel will not be endorsing MIPs going forwards. Instead, they encourage MIPs to read and follow the Best Practice Guidance wherever possible.

In the registration form below, we ask that you provide information on your MIP, including an abstract and its current stage of development, and at least one lead scientific and technical contact. We hope to make MIP contact details available on the website to ease collaboration, but please note that you can opt out of this information being publicly available.

There is no deadline for registration but early engagement will ensure your MIP information is available and you will be kept informed of the latest MIP-relevant developments in planning this phase of CMIP.
