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.

III.G CCM3.6 T42 15-Year (1978-1993) Simulation: /CCSM/cam/u3527a


Table of Contents for this Case:



A. Case Description.

/CCSM/cam/u3527a is a 15-Year (1978-1993) seasonal simulation, using AMIP monthly averaged SSTs, with CCM3.5.27 (bit-for-bit with CCM3.6). The SST data set is the Standard CCM3 T42 AMIP monthly averaged SSTs values provided with CCM3.6.

/CCSM/cam/u3527a covers the period from September 1, year 1978 to October, year 1993. 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/u3527a are:

      NCDATA  = 'SEP1.T42.0198.nc',
      BNDTVS  = 'sst_jan1978-sep1993.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/u3527a covers the period from September 1, year 1978 to October, year 1993 The data are packed 1-to-1. Daily averages were also output to the ha series of auxiliary tapes. Daily maximums were also output to the hFALSE series of auxiliary tapes. Daily minimums were also output to the hFALSE series of auxiliary tapes. 6 hour instantaneous output files were output to the hFALSE series of auxiliary tapes. The output data from this run were written in CCM2 history tape format.

The MSS pathnames for the auxiliary daily-averaged output data from this case are:

     /CCSM/cam/u3527a/ccm3/hist/hannnn 

where nnnn = 0001, 0002, ..., 0183. The MSS pathnames for the auxiliary daily maximum output data from this case are:

     /CCSM/cam/u3527a/ccm3/hist/hFALSEnnnn 

where nnnn = 0001, 0002, ..., 0100. The MSS pathnames for the auxiliary daily minimum output data from this case are:

     /CCSM/cam/u3527a/ccm3/hist/hFALSEnnnn 

where nnnn = 0001, 0002, ..., 0100. The MSS pathnames for the auxiliary 6-hour instantaneous output data from this case are:

     /CCSM/cam/u3527a/ccm3/hist/hFALSEnnnn 

where nnnn = 0001, 0002, ..., 0100.

All of the output datasets are in IEEE history tape format. Annual averages for Case /CCSM/cam/u3527ac are available as series of MSS datasets.

  /CCSM/cam/u3527ac/ccm3/hist/yyyy-01_12     (annual average for each year)

Ensamble averages for Case /CCSM/cam/u3527ac are available as series of MSS datasets.

  /CCSM/cam/u3527ac/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/u3527ac are available as series of MSS datasets.

  /CCSM/cam/u3527ac/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 a different MSS directory as noted above. The post-processed datasets are all in COS-blocked Cray-format. In addition to the post-processed datasets there are COS-blocked Cray versions of the output files in this MSS directory as well.

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