Query related to the organic carbon variables while using RADM2-MADE/SORGAM as a chemistry option

[Ankan]

Dear all,
I am running WRF-Chem version 3.9.1 using RADM2-MADE/SORGAM as a chemistry option (chem_opt=2). After getting the successful run, I found the following variables related to organic carbon in the model output:

So, If I want to compute the organic carbon mass concentration, do I have to take the sum of all these variables?
Can anyone please guide me on this? That will be very helpful for me. Thank you for your time and consideration.
