	ELSE IF ( Is_ComplexSOA ) THEN
	! dry SNA and OM mass, in unit of ug/m3
	State_Chm%AerMass%SNAOM(I,J,L) = ( State_Chm%AerMass%SO4_NH4_NIT(I,J,L) + State_Chm%AerMass%OCPO(I,J,L) + State_Chm%AerMass%OCPI(I,J,L) + State_Chm%AerMass%TSOA(I,J,L) + State_Chm%AerMass%ASOA(I,J,L) + State_Chm%AerMass%ISOAAQ(I,J,L) ) * 1.0e+9_fp
	! ratio between OM and SNA, unitless
	State_Chm%AerMass%R_OMSNA(I,J,L) = (State_Chm%AerMass%OCPO(I,J,L) + State_Chm%AerMass%OCPI(I,J,L) + State_Chm%AerMass%TSOA(I,J,L) + State_Chm%AerMass%ASOA(I,J,L) + State_Chm%AerMass%ISOAAQ(I,J,L) )/ State_Chm%AerMass%SO4_NH4_NIT(I,J,L)

Here the OM is essentially OCPISOA, which is already calculated above according to SOA schemes(simplesoa, complexsoa and complexsoa_svpoa). The current procedure misses handling complexsoa_svpoa where OCPI is replaced by OPOA.
