Talk:Installing CCSM4

If I wish to set up my own CCSM repository for different compsets, what are the required edits to Macros.tcs, etc.?

The compsets are specified when you are setting up a specific simulation, and are hard coded into the source. If by this you mean that you would like to create your own specific compsets other than those provided by NCAR. Then either: 1) you would create your own CCSM code repository and then edit the file (in: $CCSM_SRC_DIR/scripts/ccsm_utils/Case.template In this file you would add a compset e.g:

 <compset NAME="B_2000_CO2_400ppmv" SHORTNAME="B_CO2400"
        DESC="All active components, present day"
        COMP_ATM="cam" COMP_LND="clm" COMP_ICE="cice" COMP_OCN="pop2" COMP_GLC="sglc"
        CCSM_CCOST="0"
        CCSM_CO2_PPMV="400.0"
        CCSM_BGC="CO2A"
        CAM_CONFIG_OPTS="-phys cam4"
        CLM_NML_USE_CASE="2000_control" 
        CLM_CO2_TYPE="diagnostic"
        BUDGETS="TRUE" /> 

or 2)

Create a file b_2000_co2_400.xml with the following contents above:

 <compset NAME="B_2000_CO2_400ppmv" SHORTNAME="B_CO2400"
        DESC="All active components, present day"
        COMP_ATM="cam" COMP_LND="clm" COMP_ICE="cice" COMP_OCN="pop2" COMP_GLC="sglc"
        CCSM_CCOST="0"
        CCSM_CO2_PPMV="400.0"
        CCSM_BGC="CO2A"
        CAM_CONFIG_OPTS="-phys cam4"
        CLM_NML_USE_CASE="2000_control" 
        CLM_CO2_TYPE="diagnostic"
        BUDGETS="TRUE" /> 

]]

and then when you create_newcase, you invoke the following additional argument

  create_newcase -compset_file <path>/b_2000_co2_400.xml 

where <path> is the pathname where the xml file resides.
