CICE Consortium

A Sea Ice Modeling Consortium for the Community

CICE’s community of stakeholders and primary developers has formed a new sea ice modeling Consortium as a vehicle for collaboration and sharing, to maintain the current CICE model for existing and new users, to incorporate and maintain new research and development, and to accelerate scientific sea ice model development and its transfer into operational use.

Development and maintenance of the Los Alamos sea ice model, CICE, has been led and coordinated by the Department of Energy since the early 1990s. Over the past two decades, a broad community of climate and weather forecasting groups has adopted the code. As the Department of Energy continues to develop a next generation of climate models for energy, continued support of CICE is needed while the community continues to improve and use the model.

Although the initial focus of the Consortium is on the CICE sea ice model, there is a desire to continue our collaborations in the longer term, beyond the life of CICE. Therefore the Consortium will be set up as a framework able to evolve with general sea ice model contributions in the future.

The Consortium’s initial workshop was held October 26-27, 2016, in Santa Fe, New Mexico. Participants included representatives from the U.S. Department of Energy, the U.S Department of Defense (Naval Research Laboratory Stennis Space Center and the Naval Postgraduate School), the National Oceanic and Atmospheric Administration (numerous groups including the National Weather Service, Earth System Research Laboratory and the Geophysical Fluid Dynamics Laboratory), the National Science Foundation (National Center for Atmospheric Research), Environment and Climate Change Canada, and the UK Met Office.

General goals for the workshop encompassed elucidation, discussion, and clarification of participants’ expectations for the Consortium, their requirements for both the Consortium and the code itself, a governance structure for the Consortium including decision-making and code management processes, the responsibilities of Consortium Members, model users and code contributors, and an initial implementation plan.

Who can be a CICE Consortium Member?

Initially, Consortium Members are the entities (agencies or institutions) that are contributing in-kind FTE funding to support the CICE model as part of the Consortium. Each entity is responsible for maintaining part of the code and assisting others to incorporate new code developments. CICE developers who are not Consortium Members will be able to access the code and contribute their developments for use by the community, via the Consortium's procedures and with help from Consortium Members. The role of the Consortium is not to develop the model, but to aid the community in its development of the code. (Consortium Members may also develop the code under non-Consortium funding streams.)

For more information

The existing ciceusers mailing list will be used to communicate with the larger CICE community, while other communication channels are put in place. To subscribe, send an e-mail to ​listmanager@… (listmanager at with the message "subscribe cice-users". We will need to confirm your request before you are officially added.
