ocean tracer count problem

Hi everyone,I have a (probably very easy-to-fix) issue with the passive tracers. I am new to pop model and i wanted to turn on abio_dic_dic14_on to .true. in the namelist to see the d14c variables.I thought the model script would automatically increment the number of tracers (NT) accordingly but it doesnt happen in my case and i have runtime errors stating the mismatch between expected NT and cumulative NT. I guess i am missing some other flags or code modifications to properly include the abio_dic_dic14 variables in my run. Can anyone point me to the right direction please? Thanks a lot,Altug

Hi Altug, Rather than setting abio_dic_dic14_on in the namelist, you need to change OCN_TRACER_MODULES in env_run. Try running $ ./xmlchange -a OCN_TRACER_MODULES=abio_dic_dic14 From your case directory (this will add "abio_dic_dic14" to the list of tracer modules in env_build.xml). You will need to rebuild your case: $ ./case_build --clean-all; ./case_build Also, you don't need to manually set abio_dic_dic14_on -- it will be set to true automatically based on this XML variable.
 
Thanks a lot Michael! It worked now.Additionally, how can i see C isotope outputs from my run? I'm interested in the C13, C14 fields, do i need to modify tavg namelists? Best,Altug
