Output the variable about surface forcing of BC in snow in CLM5

[zhangmeixin]

I want to output the variable about surface forcing of BC in snow in CLM5, but I dont find it in 1.2.5. CTSM History Fields — ctsm release-clm5.0 documentation
But the variable "SNOBCFRCL" exsited in https://www2.cesm.ucar.edu/models/c.../doc/UsersGuide/history_fields_table_40.xhtml, when I add SNOBCFRCL to user_nl_clm (already set the -snicar_frc on in CLM_CONFIG_OPTS), the error occurred as

so how to output the radiative forcing of BC in snow in CLM5?

I found that in SurfaceRadiationMod.F90：if use_snicar_frc=true, the the variable will be add to the master field. I already set "CLM_CONFIG_OPTS" value="-phys clm5_0 -snicar_frc on">But I don't konw why no output of SNOBCFRCL....

In the case that you are running, you can look in the lnd_in file: is use_snicar_frc = .true. or .false.?

If .false., then you should set it to .true. in the case's user_nl_clm.

Thanks for your reply！ I check the lnd_in file and found there are no settings for “use_snicar_frc” in lnd_in file.
I will set use_snicar_frc = .true. in user_nl_clm and then try to run again.

After set “use_snicar_frc” =true, the variable ouput.
Thank you very much!!
