Calculation of PMF_OC in ELMO

[cgnolte]

Description There is a bug in the calculation of the ELMO variable PMF_OC (organic carbon in the Aitken and accumulation modes) causing non-carbon organic mass to be included.

Solution Modify lines 2590-2599 of ELMO_PROC.F as follows:

     CASE ( ID_PMF_OC )
        ! Sum up primary organic aerosol species normalized to
        ! just carbon mass
        VAL = 0.0
        DO IOA = 1,N_OA_NotTracers
           IF ( OASPC( IOA )%OMtoOC .GT. 0.0 ) THEN
              VAL = VAL + SUM( AEROSPC_CONC( MAP_OAtoAERO(IOA),: ),
 &                        MASK = AEROMODE(:)%FINE_MASK ) 
 &                      / OASPC( IOA )%OMtoOC
           END IF
        END DO
        OUTVAL = VAL
