Fire emissions can be calculated online within CLM/CTSM.
Namelist specification
Emissions calculated in CLM are matched to chemical species in CAM-Chem with a namelist that can be included in user_nl_cam ...
Emission factors file
Emission factors are specified in a netcdf file.

Updates:
- /glade/work/emmons/fire_inputs/fire_emission_factors_78PFTs_c20220111.nc: added bc_a4 (=BC), pom_a4 (=1.4*OC), num_a4_bc, num_a4_pom, so4_a1 (=0.025*SO2), num_a1_so4
- /glade/work/emmons/fire_inputs/fire_emission_factors_78PFTs_c20251010_v0.nc: added SVOC (=0.6*1.4*OC); IVOC (20% of BIGALK, BIGENE, TOLUENE, CH3OH, scaled by MW)
- /glade/work/emmons/fire_inputs/fire_emission_factors_78PFTs_c20251010_v1.nc: added SOAE (=0.5954D0*ISOP + 2.5592D0*BENZENE + 8.5371D0*IVOC + 16.650D0*SVOC + 8.2367D0*TOLUENE + 6.5013D0*XYLENE + 5.1004D0*C10H16)
