CSM Experiment Series g005

Active: sea-ice & ocean
Dummy: atmosphere & land

Models used:

  • the dummy atmosphere+land using CCM history data
  • the NCAR global ocean
  • the NCAR sea-ice model.

    This case used a dummy atmosphere model (based on CCM output data) to spinup the active ice and active ocean models. This spinup provided ice and ocean initial conditions for the b001.nn series, which is the control experiment presented in the May 1996 CSM workshop.

    Some results:

  • From the ice model

    Noteworthy:
  • IC's are 1 Jan 220 from g005.13
  • atm feeds drv monthly avg data fields, w/ albedo feedback
  • ocn in accel mode w/ dt=4.8-48hr T & S, .8hr (u,v)
  • essentially a continuation of g005.13 except a coding error wrt fresh water flux into ocean was corrected

    Noteworthy:
  • IC's are 0100-Jan-01 from g005.11
  • essentially a continuation of g005.11 except...
  • ...initial ice & ocn source code differs from g005.11
  • ...drv does E+P=0 balance over non-land-locked ocn domain only
  • all source codes have been modified during this run (bug fixes and other tweaks)
  • year 220: ocn accel is turned off
  • year 220: atm data is switched to daily avg fields
  • year 230: provides ocn & ice IC's for case b001.01
  • presented at the 1st CSM Workshop in May 1996
    as part of the g005.11 + g005.13 + b001 series
