Incorporated models or components:


Spatial dimensions 2D
Spatial extent Global
Model domain Marine, Cryosphere
One-line model description Los Alamos sea ice model
Extended model description CICE is a computationally efficient model for simulating the growth, melting, and movement of polar sea ice. Designed as one component of coupled atmosphere-ocean-land-ice global climate models, today’s CICE model is the outcome of more than two decades of community collaboration in building a sea ice model suitable for multiple uses including process studies, operational forecasting, and climate simulation.
