CCSM Research Tools: The NCAR CSM Ocean Model

Introduction

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]
