CAM6 Prescribed SST AMIP Ensemble

The CVCWG has created a 10-member Tropical AMIP ensemble with prescribed SST and sea-ice forcing using CAM6 within the CESM2.1.1 tag. Details on this ensemble and instructions for how to access the data can be found below.

We kindly ask that you acknowledge the CVCWG when presenting results based on the CAM6 Prescribed SST AMIP Ensemble in either oral and written form.

Project Details

  • Simulation Names:
    • f.e21.FHIST.f09_f09.historical.ersstv5.toga.ensXX, XX = 01-10
  • Model Version: CESM2.1.1   Codebase | Documentation
  • Resolution: 0.9x1.25 (CESM nominal 1o grid)
  • Years: 1880-2014
  • Ensemble Size: 10 members
  • Time Frequencies Saved: Monthly, Daily
  • Machine: NCAR:Cheyenne
  • Compsets: FHIST
  • Additional Notes: SST's from 28S:28N are set to time-varying SST's from ERSSTv5. A transition/linear interpolation zone exists from 28:35 degree latitudes. From 35 degrees polewards full-period climatological SSTs (ERSSTv5)/sea-ice (HadISST1) are set. All simulations are initialized from the 11th CESM2 historical member on January 1st, 1880, with each ensemble member receiving a small change in the initial air temperature via namelist setting PERTLIM. All CMIP6 time-varying external, natural and anthropogenic forcings were specified in this ensemble.

Data Acquisition

The CESM2 IPCC/AMIP Tropical AMIP 10-member ensemble is available from NCAR/CISL's campaign store or on the NCAR machine casper at /glade/campaign/cesm/development/cvwg/CESM2.1_TOGA_ERSSTv5. If you do not have access to the CISL campaign store or NCAR's casper machine you can contact the CVCWG liaisons for assistance.
