Description
I note first that I am actually using the dev branch, but I think this is the same in Flexpart V10.x
Currently, the amounts of SO2 and CO in Flexpart do not decay via reaction with OH. This is because the variables POHCCONST and POHDCONST in the files SPECIES_xxx are set to a negative value. The user cannot turn on the reaction with OH just by removing the - signs because the absolute values are placeholders, used for all species where reaction with OH is not enabled. (If you cluelessly remove the - signs for SO2, it decays far too fast.)
I would be very grateful if someone could supply me with the correct values for POHCCONST, POHDCONST and POHNCONST for SO2 (and, less urgently, CO). The ideal thing would be for the correct values to go into the SPECIES_xxx files supplied with Flexpart. But I would be happy for now to get the values as a reply in this ticket --- I can easily put them into SPECIES_xxx myself. (This would also leave the values where a person searching the web could find them.)
If no-one knows the right values and I manage to dig suitable ones out of the literature I shall add them to this ticket.
Progress so far on the SO2+OH reaction:
