A. Case Description.

/OLSON/ccm3/sld012d is a 15-year T42 seasonal simulation, using analyzed monthly averaged SSTs with Beta-CCM3 (built with the mv1 library). The SST data set is the Standard AMIP T42 climatological SST values from Dec 78 to Dec 88 and COADS data for Jan 89 to Sep 93.

/OLSON/ccm3/sld012d covers the period from 16 December of year 78 to 1 September of year 93. Atmosphere and LSM (Land Surface Model) Initial Conditions datasets were created from 16 Dec of year 10 of /OLSON/ccm3/sld012b, a 10-year CCM3 simulation using climatological monthly averaged SSTs.

B. Initial and Boundary Datasets.

The initial and boundary datasets used in Case /OLSON/ccm3/sld012d are: 

      NCDATA = '/OLSON/datasets/T42/CCM3DEC16',
      BNDTI  = '/ccm2/T42/tibds',
      BNDTVS = '/JET/amip/datasets/Dec78-Sep93.global.sst',
      BNDTVO = '/ccm2/T42/ozn',
      fsurdat = '/crestone/u1/bonan/lsm/datasets/som/surfdat'
      finidat = '/crestone/u0/olson/lsm/datasets/t42/initdat_CCM3.dec16'
and resolution parameters: 
      HRES  T42              PCNST   1 
      PLEV   18              PTRM   42 
      PLON  128              PTRN   42 
      PLAT   64              PTRK   42

C. Output History Datasets.

/OLSON/ccm3/sld012d covers the period from 16 December of year 78 to 1 September of year 93. Two different output datasets were written, a Primary history tape and and Auxiliary history tape.

The Primary history tapes contain the standard set of CCM3 history fields, output as monthly averages 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 .../01-79 contains model data averaged over the month of January 79. The averaging period extends from the first timestep of the first day of January of year 79 through the first timestep of the first day of February of year 79. The date in the history tape header will be 00Z 1 February 79).

The Auxiliary history tapes contain a number of history fields output as 24-hour averages for each day of the run. Each daily average is valid for the previous 24 hours (i.e. the daily-average written at 00Z Jan 15 is the average for all timesteps during the time period of the 1st time-step after 00Z Jan 14 through 00Z Jan 15).

Both the Primary and Auxiliary data are packed 4-to-1. All output data from this run was written in CCM2 history tape format.

The MSS pathnames for the Primary (monthly-averaged) output data from this case are: 
     /OLSON/ccm3/sld012d/hist/mm-yy
where mm is a two digit month (mm = 01, 02, ..., 12) and yy is a two digit year (yy = 79, 80, ..., 93).

The MSS pathnames for the Auxiliary (daily-averaged) output data from this case are: 
     /OLSON/ccm3/sld012d/hist/hannnn
where nnnn = 0001, 0002, ..., 0179

D. Description of post-processed datasets

Monthy Average and Standard Deviation datasets

Ensemble averages of the Primay (monthly-averaged) output history tapes from Case /OLSON/ccm3/sld012d are available for January and July

The MSS pathnames for the post-processed data from this case are: 
  /OLSON/ccm3/sld012d/hist/01-8088   ( average for all Januarys
                                       from year 80 to year 88) 
  /OLSON/ccm3/sld012d/hist/07-8088   ( average for all Julys
                                       from year 80 to year 88)
