ERROR "in validate_variable_value " when running the $CASE.submit

[yuqiang_zhang@duke_edu]

Hi All, I was succefully ported the CESM 1.2.2 to our local machine with the compset "F_2000_MOZMAM_CN". However, when I tried to run the CESM with the $CASE.submit command, it gave me the following error messages: CESM BUILDNML SCRIPT STARTING  - To prestage restarts, untar a restart.tar file into /netscr/yuqiangz/CESMSCRATCHROOT/zyq_test_mpich2_netcdf4.2/run infile is /nas02/depts/ese/chaq/yuqiangz/CAM_v5.3/cesm1_2_2/zyq_test_mpich2_netcdf4.2/Buildconf/cplconf/cesm_namelistCAM build-namelist - ERROR: Invalid namelist variable in '-infile' /nas02/depts/ese/chaq/yuqiangz/CAM_v5.3/cesm1_2_2/zyq_test_mpich2_netcdf4.2/Buildconf/camconf/cesm_namelist. ERROR: in validate_variable_value (package Build::Namelist): Variable name cam_chempkg has values that does NOT match any of the valid values: 'waccm_mozart' 'waccm_ghg' 'trop_mozart' '                                         trop_ghg' 'trop_bam' 'trop_mam3' 'trop_mam7' '                                         super_fast_llnl' 'super_fast_llnl_mam3' 'none '.ERROR: cam.buildnml.csh failed ERROR from preview namelist - EXITING I checked that "cam_chempkg = 'trop_mozart__mam3'" in the file:/nas02/depts/ese/chaq/yuqiangz/CAM_v5.3/cesm1_2_2/zyq_test_mpich2_netcdf4.2/Buildconf/cplconf/cesm_namelist I don't understand why I have errors? Should this chemical mechanism be included in the checking step?

cesm1_2_2 (cam5_3) does not support the chem package trop_mozart_mam3.

Hi,I use "F_2000_MOZMAM_CN" compset, and I don't think I specify the chemical mechanism mannually. It was all done by the ./cesm_setup and $CASE.run script. So my quesiton is why this mechanism appears in my file? When I mannually changed the mechanism to "trop_mozart" in the file, and $CASE.build again, it gave me warming that "CAM Namelist ERROR: User may not specify the value of cam_physpkg.This variable is set by build-namelist based on informationfrom the configure cache file.ERROR: cam.buildnml.csh failedERROR: /nas02/depts/ese/chaq/yuqiangz/CAM_v5.3/cesm1_2_2/zyq_test_mpich2_netcdf4.2/preview_namelists failed: 25344"

The way the chemistry package is specified to cam is by using the -chem option to CAM's configure command.  So to use trop_mozart chemistry configure must get the argument "-chem trop_mozart" and the namelist variable cam_chempkg is set by build-namelist using information that it finds in the config_cache.xml file.  The user is not allowed to set cam_chempkg directly because the chemistry is a build time option, not a run time option.Someone else may be able to help with the compset problem.

Hi eaton,Thanks for your reply. I noticed the configure option when I compiled the CAM stand-alone model. However, I don't know where to add the " "-chem trop_mozart"  option when porting CESM into a local machines with the compnsets. Any suggestions?Regards,Yuqiang

I see now that my comment #2 is incorrect.  The trop_mozart_mam3 chemistry package is supported in the cesm1_2_2 release.  The error from build-namelist is due to namelist variable cam_chempkg being set by the user.  This variable should only appear in the file produced by the build-namelist command, i.e., atm_in.  If it appears anywhere else that instance should be removed.  Perhaps starting from scratch would help.
