The NCAR Community Climate Model (CCM3)


The NCAR Community Climate Model (CCM3) is no longer supported, use the Community Atmosphere Model (CAM) for the latest model that includes limited support for use of the community.

II.D CCM3.6 T42 10-Year (05-15) Simulation: /CCSM/cam/ccm3527


Table of Contents for this Case:



A. Case Description.

/CCSM/cam/ccm3527 is a 10-Year (05-15) seasonal simulation, using climatological monthly averaged SSTs, with CCM3.5.27 (bit-for-bit with CCM3.6). The SST data set is the Standard CCM3 T42 climatological monthly averaged SSTs values provided with CCM3.6.

/CCSM/cam/ccm3527 covers the period from September 1, year 5 to October, year 15. The atmosphere and land Initial Conditions datasets were the standard CCM3.6 datasets.


B. Initial and Boundary Datasets.

The initial and boundary datasets used in Case /CCSM/cam/ccm3527 are:

      NCDATA  = 'SEP1.T42.0198.nc',
      BNDTVS  = 'T42M5079.nc',
      BNDTVO  = 'ozn.0596.r8.nc',
      finidat = 'CCM3.5LSMICSEP1.0198.nc'

and resolution parameters:

      HRES  T42              PCNST   1 
      PLEV   18              PTRM   42 
      PLON  128              PTRN   42 
      PLAT   64              PTRK   42

C. Output History Datasets.

/CCSM/cam/ccm3527 covers the period from September 1, year 5 to October, year 15 Monthly averages of model fields exist on history tapes for each month of the run. Each monthly average is valid for the current month and current year of the date encoded into the MSS filename. The date in the history tape header will be the first timestep of the first day of the next month (i.e. the monthy-average tape named .../0005-09 contains model data averaged over the month of September 1, year 5. The averaging period extends from the first timestep of the first day of September 1, year 5 through the first timestep of the first day of the next month. The date in the history tape header will be 00Z 1 October, year 0). The data are NOT packed. The output data were written to the primary history tape only; no auxiliary data were written. The output data from this run were written in CCM2 history tape format.

. The MSS pathnames for the monthly-averaged output data from this case are:

     /CCSM/cam/ccm3527/ccm3/hist/yyyy-mm

where yyyy = the year and
mm = the month

All of the output datasets are in IEEE history tape format.


D. Description of post-processed datasets

Monthy Average datasets

Monthly averages for Case /CCSM/cam/ccm3527c are available as series of MSS datasets.

The MSS pathnames for the post-processed data from this case are:

  /CCSM/cam/ccm3527c/ccm3/hist/yyyy-mm     (monthly average for each month)

where mm is a two digit month (mm = 01, 02, ..., 12) and yyyy is a four digit year (yyyy = 05 through 15). Annual averages for Case /CCSM/cam/ccm3527c are available as series of MSS datasets.

  /CCSM/cam/ccm3527c/ccm3/hist/yyyy-01_12     (annual average for each year)

Ensamble averages for Case /CCSM/cam/ccm3527c are available as series of MSS datasets.

  /CCSM/cam/ccm3527c/ccm3/hist/DJF-yyyy-yyyy     (ensamble average)

  where DJF-yyyy-yyyy refers to the average over December, January, Feburary for the winter of the given year

Ensamble averages for Case /CCSM/cam/ccm3527c are available as series of MSS datasets.

  /CCSM/cam/ccm3527c/ccm3/hist/JJA-yyyy-yyyy     (ensamble average)

  where JJA-yyyy-yyyy refers to the average over June, July, August for the summer of the given year

The post-processed datasets are in COS-blocked Cray-format and have the different case name as noted above.

Remember CCM3 is now unsupported, use CAM for the latest Atmospheric Model for use of climate science.
