The NCAR CCSM sea ice column model is derived from the three-dimensional, global model under development for CCSM version 2. The column version contains all of the physics from the global model with the exception of ice dynamics and transport. Highlights of the model physics include a five-category thickness distribution driven by prescribed lead opening and ridging rates, heat conduction through multiple vertical layers with an explicit brine-pocket paramerization to resolve internal melting, and radiative transfer in the ice interior resolved into two spectral bands.
The column model based on the CCSM sea ice model version 4.2.2 as of June 3, 2001, may be downloaded as a gzipped tarfile: 3jun.tar.gz. The file contains source code, forcing data, and scripts to compile the model. A sample directory of output from the standard run is included.
The data sets used to force and initialize the model are described here notes_forcing_data.
Several README files are included describing how to compile and run the model. The file README_column contains my log of details that are specific to the column version. Dated entries are added sequentially, so the most recent notes appear are at the end. A log of the changes made in various distributions for the global model can be found in the file ChangeLog which is maintained by Julie Schramm.
