CESM Models

CCSM3.0 Control Run Model Output

 

To document and validate CCSM3.0, various multi-century control runs were carried out. All output data from these control runs is available to the public. The Earth System Grid (ESG) is the primary method for distributing this output data (more information below). Also available on this web page is a sampling of diagnostic plots from these control runs.

Another series of CCSM3 experiments is underway which will provide data for an upcoming IPCC Assessment Report. Data from these experiments will be made available after CCSM3 results are submitted to the IPCC.

Model Output Data

CCSM3.0 output data files can be downloaded from the CCSM Dataset Catalog on the ESG (registration required). This is post-processed data that includes, for each case:

For all control runs, monthly average data were saved and many post-processed time-series were created. All output data from these runs is available to the public. A large (2TB) subset of this data is available via the ESG, which is the primary method for distributing CCSM3 output data. The full set of original output data is archived on NCAR's Mass Storage System (NCAR account/login required). A sub-set (1TB) of post-processed output data is also available "inside the firewall" at NCAR on the nfs-mounted data partition /ccsm/data (NCAR account/login required).

Diagnostic Plots

While far from complete, these diagnostic plots offer significant insight into the control run results. If you'd like to see more plots available here, contact the corresponding working group liaison to make your request.
