Title: CICE, The Los Alamos Sea Ice Model

Abstract

The Los Alamos sea ice model (CICE) is the result of an effort to develop a computationally efficient sea ice component for a fully coupled atmosphere–land–ocean–ice global climate model. It was originally designed to be compatible with the Parallel Ocean Program (POP), an ocean circulation model developed at Los Alamos National Laboratory for use on massively parallel computers. CICE has several interacting components: a vertical thermodynamic model that computes local growth rates of snow and ice due to vertical conductive, radiative and turbulent fluxes, along with snowfall; an elastic-viscous-plastic model of ice dynamics, which predicts the velocity field of the ice pack based on a model of the material strength of the ice; an incremental remapping transport model that describes horizontal advection of the areal concentration, ice and snow volume and other state variables; and a ridging parameterization that transfers ice among thickness categories based on energetic balances and rates of strain. It also includes a biogeochemical model that describes evolution of the ice ecosystem. The CICE sea ice model is used for climate research as one component of complex global earth system models that include atmosphere, land, ocean and biogeochemistry components. It is also used for operational sea icemore » forecasting in the polar regions and in numerical weather prediction models.« less

Other Software Info:
The CICE model has been developed since 1994 and enhanced greatly through collaborations with members of the sea ice modeling community outside of LANL. This release moves the code into an open source repository for ongoing use and development via the CICE Consortium. Since the most recent CICE release in March 2015, some parts of the code were refactored to isolate vertical columns that can be computed without reference to neighboring grid cells or other code infrastructure.
