The CSM Sea Ice Model (CSIM)
Introduction
The sea ice component of CSM, referred to as the CSM Sea Ice Model or
CSIM, includes active thermodynamic and dynamic processes. It
is driven by the heat, momentum, and freshwater fluxes provided at the
upper and lower ice boundaries by the atmospheric and oceanic model
components, respectively. CSIM, in turn, provides the appropriate
boundary fluxes required by the atmosphere and ocean in the presence
of ice. The
CSM Flux Coupler
facilitates and manages the
exchange of fluxes between CSM component models and exercises the
required care to assure conservation of heat, momentum, and freshwater
within the model climate system.

Publicly Released Versions
- Version 0.91 (June 1996)
This is the first release of the CSIM code and is essentially
the same as that used for the fully coupled experiment presented
at the May 1996 CSM Workshop. This code was also used
for a 300 year fully coupled run and a companion run with increasing CO2
during the fall and winter of 1996/1997. These simulations were
presented at the June 1997 CSM Workshop (also see the 16 May 97
issue of Science).

User's Guide to the NCAR CSM Sea Ice Model, Version 0.91
- Source Code (download)
This is a gzipped tar file called ice_0.91.tar.gz. When unzip'ed and
untar'ed, you will have a CSIM source code directory called CSIM_0.91.
This initial release is intended for use on NCAR Cray machines only.
Be sure the read the README and README.CSM files
included with the CSIM source code.
- Version 2.2.6 (July 1998)
This version of the code is essentially the same as Version 0.91.
The most notable additions to this code are the inclusion of
lower resolution grid domains (the x3 and x3p), and the ability
to use sea ice concentration climatology datasets to integrate
the system in climatology mode. Other improvements include
enhanced diagnostics and portability.
