[FEATURE REQUEST] add MO2 + NO3 reaction #1235

Closed kelvinhb closed 1 year ago

kelvinhb commented 2 years ago

Request a new GEOS-Chem feature:

Hi team! Daniel and I think we should add a new reaction to KPP:

MO2 + NO3 = NO2 + CH2O + HO2 : 1.20d-12;

It's well-documented by IUPAC (https://iupac-aeris.ipsl.fr/htdocs/datasheets/pdf/ROO_19_CH3O2_NO3.pdf) and even though it probably won't make much difference in most of the atmosphere, it could play a role in the methyl peroxy budget under some circumstances (like remote areas where the peroxy radical lifetime is long but where long-range NOx transport can still provide an NO3 source). Let me know if there are any questions on this!

Hi @kelvinhb, thanks for the heads-up! This could be added to 14.0.0, which is the next version that we'll run benchmarks for.

kelvinhb commented 2 years ago

Sounds great!

yantosca commented 1 year ago

@kelvinhb, we are working on bringing this into 14.1.0.

This update has now been merged into the dev/14.1.0 branch.
