The NCAR CSM Ocean Model (NCOM) is a collaborative project among all of the members of the NCAR Oceanography
Section . Their 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.  NCOM can be run as ocean-only, or in coupled mode with any combination of three other model components of NCAR's Climate System Model:

• NCAR Community Climate Model (CCM)
• NCAR CSM Sea Ice Model (CSIM)
• NCAR Land Surface Model (LSM)

1.  Ocean Only:  uncoupled equilibrium runs
2.  Ocean-Ice:
3.  Ocean-Atmosphere coupled:  Atmospherically-driven runs which incorporate interannual variability
4.  Fully Coupled:

• 300-yr CSM control run
• Recent runs to 2080
• 20th Century run
• 21st Century run

Output from NCOM runs is huge!  Size depends on how many and how often variables are output.  For example, data which were output monthly for the x2' NCOM run, over 80 years, resulted in 80 yr x 12 files/yr x 40Mb/file = 39 Gb of data!
