Experiment Series g040

Active Models: sea-ice & ocean
Data Set Models: atmosphere & land

When run: June 1999

Models used:

  • atm: a "data set" model using daily average data from a CCM3 + LSM spinup run
  • lnd: a "data set" model using monthly average data from a CCM3 + LSM spinup run
  • ice: the NCAR CSM Sea Ice Model (CSIM), CSIM3.beta01
  • ocn: the NCAR CSM Ocean Model (NCOM), NCOM1.5 + mods
  • cpl: the NCAR CSM Flux Coupler, cpl4.0.3 - branch: newice1.1

    Synopsis:
    This case was a standard ocn+ice spinup run, testing new ocn & ice features. This case provides ocn & ice IC's for case b040.xx, a configuration in which all components are active models. The ocn and ice were run at the "NCOM 2x2'" resolution (nominal 2 degree), while the atm and lnd models were run at T42. The data file atmosphere model provided the coupler with daily average fields from a CCM3 + LSM spinup run. New in the ocn model is a new bottom boundary layer (BBL) and the "x2'" resolution (compared to the "x2" resolution it has higher resolution near the equator) New in the ice model is a viscous/plastic ice dynamics and an ocn/ice stress calculation internal to the ice model.

    Computer Resources:
    This run was done on a 128 processor SGI Origin 2000 ("ute" at NCAR), using 64 of the processors.
