4.1. About Development

The CICE model consists of four different parts, the CICE dynamics and supporting infrastructure, the CICE driver code, the Icepack column physics code, and the scripts. Development of each of these pieces is described separately.

Guiding principles for the creation of CICE include the following:

• CICE can be run in stand-alone or coupled modes. A top layer driver, coupling layer, or model cap can be used to drive the CICE model.
• The Icepack column physics modules are independent, consist of methods that operate on individual gridcells, and contain so underlying infrastructure. CICE must call into the Icepack using interfaces and approaches specified by Icepack.
