I am looking at organic carbon after run COMBINE and I have few questions:
PM25_OC = AOCI * PM25AT + AOCJ * PM25AC
AOCI = APOCI + ASOCI
AOCJ = APOCJ + ASOCJ
ASOCIJ = ASOCI + ASOCJ
AOCIJ = APOCIJ + ASOCIJ
When I plot the diurnal cycle (average of the hours of a month simulation) of PM25_OC and ASOCIJ, sometimes the ASOCIJ is higher than PM25_OC.
So I am a little confused with these results since PM25_OC is the sum of primary and secondary organic carbon in I and J mode, it should have higher mass than ASOCIJ.
What am I missing?
Should I use PM25_OC as Organic carbon, or should I use the sum of AOCI + AOCJ (AOCIJ)?
Another question is about the values that aerosol species are being divided by, for example:
APOCI ,ugC m-3 ,ALVPO1I/1.39 + ASVPO1I/1.32 + ASVPO2I/1.26 +APOCI
What are these values 1.39, 1.32, 1.26?
Can the community help me understand it?
Thank you so much for your attention
