cesm1.1: CRITICAL PROBLEM with the following (primarily transient CO2) component sets

The -co2_type flag in the CLM namelist is not set correctly and will result in an invalid value of co2_ppmv being received by CLM.

  • All B_RCP* component sets
  • All B_1850-2000* component sets
  • All F_AMIP* component sets
  • All B_*BPRP* and B_*BDRD* component sets
  • All B_1850_*WACCM* component sets

BUG FIX for CESM1.1:

In your $CASEROOT/Buildconf/clm.buildnml.csh (and only there) modify the following line

  • new:
    -glc_nec $GLC_NEC -co2_ppmv $CCSM_CO2_PPMV -co2_type $CLM_CO2_TYPE
  • old:
    -glc_nec $GLC_NEC -co2_ppmv $CCSM_CO2_PPMV
This problem occurs in the cesm1.1 release code.
