History fields for CLM 5 and possible non-defined EMG field?

I have been trying to run CLM and get the ground emissivity as one of the history fields. While the history fields table for CLM 5 seems to be missing here (https://escomp.github.io/ctsm-docs/doc/build/html/users_guide/setting-up-and-running-a-case/customizing-the-clm-namelist.html?highlight=history%20field), the table for a previous (http://www.cesm.ucar.edu/models/cesm1.2/clm/models/lnd/clm/doc/UsersGuide/history_fields_table_40.xhtml) says that it should be EMG. When I run the model with that history field added, I get this error:

htapes_fieldlist ERROR: EMG in fincl(           9 ) for history tape            1  not found ENDRUN: ERROR: ERROR in histFileMod.F90 at line 690


I am assuming this means that a field of that name is not defined in the master file? Is the history field name for ground emissivity different for CLM5 or do I have to activate it somehow?

Thanks!

The subroutine call to output EMG is within a "use_cn" if statement.  So maybe you are running in SP (satellite phenology) mode, not BGC mode?

I am. Is there no way to get emissivity in SP mode? I don't need to separate ground and vegetation emissivities. Is there any way to get the average emissivity of the grid directly? If there isn't, I guess I could derive it from the ground temperature and upwelling longwave radiation.
