Hello，guys！
I am using the pop2 in the cesm1.2 version. I would like to ask how to close the GM90 parameterization scheme？
What I did was add the following setting in the user_nl_pop file: hmix_tracer_choice = 'del2'
But always get an error:
Requested KAPPA_ISOP
-------------------------------------------------- --------------------
POP aborting...
FATAL ERROR: requested field unknown
Then I try to turn off kappa_isop_choice = 'bfre' setting, for example: add the output_fields = 'default -KAPPA_ISOP' statement at the end of the user_nl_pop file, but it has never been successful. I want to ask how to solve it, thank you！
