CESM Models: CSM Ocean Model Release 1.4.0
This is an archival page for informational and historical purposes only.
The NCOM model has not been in use at NCAR for almost a decade. Therefore, it is not available. For our current ocean model, please click here.
The NCAR CSM Ocean Model (NCOM) is a collaborative project among all of the members of the CGD's Oceanography Section. Our goal is to develop and maintain a suite of state of the art ocean component models both for coupled climate system integrations and as testbeds for scientific processes studies in uncoupled mode.
Ocean modellers who acquire the NCOM 1.4 source code from this site should register as an NCOM user. Updates to the NCOM will be announced to registered users and will appear on this web page from time to time in the future. If you are an active NCOM user, please check this site periodically for the most recent updates to the NCOM and its data files. [Register as an NCOM User]

Description: A collection of figures from the two degree resolution NCAR CSM Ocean Model, before and after full coupling within the overall Climate System Model. [gallery]
The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.
CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR).
