Wait for CCSM2.0.1 before running production runs!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• Datasets referenced in CCSM2.0 datm.setup.csh and dlnd.setup.csh are outdated and should not be used in production runs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.

Running the “C” runRunning 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!
