HEMCO interface for CAM-chem missing surface emission history fields (SF*)

[jimmielin]

What happened?

Reported by Behrooz Roozitalab (ACOM)

When running CAM-chem/MUSICA with HEMCO enabled the surface emission history fields (starting with SF) are unavailable.

This is due to chemistry/mozart/chemistry.F90 initializing the diagnostics based on a has_emis array of logical flags in mo_srf_emissions:

       if ( n>0 ) then
          if (has_emis(m) .or. aero_has_emis(solsym(m)) .or. ocean_emis_species(solsym(m)) .or. srf_emis_diag(n)) then
             srf_emis_diag(n) = .true.

However, the HEMCO compatibility layer for surface emissions in hco_cc_emissions.F90 does not set this flag at the time of chem_init. This does not affect the actual simulation results but the diagnostics are unavailable. An alternative is to use the HCO_<species name> history output fields.

What are the steps to reproduce the bug?

use_hemco = .true. in a CAM-chem compset and check field list
