Hi @mvieno, @mifads
As far as I understand OM25_P
is not a "real variable", but the sum of all OM
particulate contributions from the SOA species.
@mifads am I correct? Should OM25_P
contribute to PM10 dry/wet depositions?
OM25_p is not a 'real' species, but rather a very handy sum of all inert and condensed OM species. This is used as for example a compound like ASOC_ug1 has both gas and particle phase contributions. We don't want the gas-phase part counted as PM2.5 or PM10.
When calculating e.g. dry deposition, the code does not use OM25_p, but operates on each of the 'real' species separately. It calculates how much of e.g. ASOC_ug1 is gas and deposits that as gas, and the rest as particle.
Hi, thanks. That's clear now.
I am still not clear in which specie, let say, the dry dep for the particulate part of ASOC_ug1, is then accounted for in the DDEP_PM10_GROUP. As both PM10_GROUP and DDEP_PM10_GROUP do include the same variables but OM25_p.

@mifads ?
@mifads can you answer this question?
Looks like a bug for PM outputs, but probably a small one. We do account for dry dep of organics, though it is complicated by the gas-particle partitioning. As we never output deposition of PM ourselves I have never come across this. Can be added to the (long) post-summer to-do list.
@mifads
was this addressed on the code we're about to release?
Cheers, Á.
Looks like the bug is still there. In short, the model does deposit e.g. ASOC_ug1 with both its gas and particle phases, but these are not included in those output DDEP and WDEP PM groups. Hopefully we can fix it next time around!
Hi, in CM_ChemGroup PM10 group is defined as follow:
whereas in the DDEP_PM10_GROUP and WDEP_PM10_GROUP the ON25_P is missing? probably this is wanted.
thanks Massimo
