Abstract: The Community Sea Ice Model (CSIM) is a dynamic-thermodynamic model that includes a subgrid-scale ice thickness distribution. It uses the energy conserving thermodynamics of Bitz and Lipscomb (1999), with four ice layers and one snow layer in each thickness category. The ice dynamics utilizes the elastic-viscous-plastic rheology of Hunke and Dukowicz (1997). Subgrid-scale ridging and rafting is ... parameterized according to Rothrock (1975) and Thorndike et al. (1975). Horizontal advection is calculated via the new incremental remapping scheme of Lipscomb and Hunke (2004). A more complete model description can be found in the documentation.
The CCSM Climatological Data Ice Model, version 6.0 (dice6), was released in June 2004, as part of the CCSM3.0 release.
CCSM coupled model is based on a framework which divides the complete climate system into component models connected by a coupler. This design requires four component models -- atmosphere, sea-ice, land, and ocean -- each connected to the Coupler, and each exchanging data with the Coupler only.
The Community Sea Ice Model (CSIM) is the sea ice component of CCSM that will run uncoupled from the other CCSM components. The physics in the uncoupled ice model are identical to those in the ice model used in the fully coupled system. This release includes the CSIM source code, documentation, input and forcing data.
The CCSM3.0 coupled model, released in June, 2004, provides the community with a coupled model framework for carrying out climate simulations. Upgrades from CCSM2.0.1 release can be found in the Introduction section of the Users Guide CCSM coupled model is based on a framework which divides the complete climate system into component models connected by a coupler. This design requires four
component models -- atmosphere, land, ocean, and sea-ice -- each connected to the coupler, and each exchanging data with the coupler only. From a software engineering point of view, the CCSM is not a particular climate model, but a framework for building and testing various climate models for various applications. In this sense, more than any particular component model, the coupler defines the high-level design of CCSM software.
CICE is a numerical model of sea ice. It is designed to be a component of global climate models, although it can also be used in standalone mode for sea ice simulations. CICE has been developed to be compatible with the Parallel Ocean Program (POP) and the Community Climate System Model.
