Quick Summary

• Download CCSM2.0 source code, scripts, and input
  datasets
• Set up active ocean data atm,ice,lnd -- use
  the GUI!!!
• Edit the ocean-model namelist file pop_in
• Edit the ocn.setup.csh script
• Run one-month test run
• Wait for CCSM2.0.1 release before making
  production runs!

Download CCSM2.0 source code, scripts, and input
datasets

• On local system
• mkdir CCSM2.0
• Go to the CCSM2.0 website www.ccsm.ucar.edu/model
  s/ccsm2.0
• Find Model Source Code section
• Download ccsm2.0.tar.gz into CCSM2.0 directory
• Find Model Input Data section
• Download T42/gx1v3 input datasets tar file into
  CCSM2.0 directory
• On local system

Set up active ocean data atm,ice,lnd

• Set up a new directory with a collection of
  scripts to run the active ocean data
  atmosphere, ice, and land models through the
  coupler -- use the GUI!!!
• How do you use the GUI?

How do you use the GUI?

• cd CCSM2.0/ccsm2.0/scripts/gui_run
• issue the perl command ccsm_gui.pl
• the GUI will pop up
• select C run active ocean, coupler, and data
  atmosphere, ice, and land
• ocn.setup.csh
• cpl.setup.csh
• datm.setup.csh
• dice.setup.csh
• dlnd.setup.csh

Edit the ocean-model namelist file pop_in

• cd CCSM2.0/ccsm2.0/scripts/newtest.001
• mkdir src.ocn
• cd src.ocn
• cp CCSM2.0/ccsm2.0/models/ocn/pop/
• input_templates/gx1v3_pop_in .

Edit gx1v3_pop_in

• 1. forcing_shf_nml
• luse_cpl_ifrac .true.
• 2. ice_nml
• lactive_ice .false.
• 3. probably one new namelist parameter will be
  released with CCSM2.0.1 -- will be announced if
  needed

15
Edit the ocn.setup.csh script

• cd CCSM2.0/ccsm2.0/scripts/newtest.001
• edit ocn.setup.csh
• note line in ocn.setup.csh script
• set my_path SCRIPTS/src.ocn
• change
• sed -f EXEDIR/commands.sed SRCDIR/input_template
  s/OCN_GRID_pop_in
• to
• sed -f EXEDIR/commands.sed my_path/OCN_GRID_p

Wait for CCSM2.0.1 before running production runs!

• Datasets referenced in CCSM2.0 datm.setup.csh and
  dlnd.setup.csh are outdated and should not be
  used in production runs
• Datasets referenced in CCSM2.0.1 datm.setup.csh
  and dlnd.setup.csh will be obtained from
  active-atm, active-lnd branch run (an F run
  branched from the CCSM2.0 control run)
• Wait for CCSM2.0.1 release before running any
  production runs! Repeat preceding process with
  CCSM2.0.1 tar file.

18
Running the C run

• The GUI set up a one-month test run for you --
  now submit it to your target machine
• (llsubmit newtest.001.run on the IBM)
• Review the output from the .log. files from
  each component
• Review the output from the ocean log file -- all
  namelist values are echoed into the log file, so
  check to make certain that the changes you made
  to lactive_ice and luse_cpl_ifrac were actually
  used in your run
• Wait for the CCSM2.0.1 release before running the
  C run in production mode!
