Our new aqueous SOA parameterization published in Atmos. Chem. Phys.

We are proud to announce the acceptance and publication of the final version of our latest manuscript in the open access journal Atmospheric Chemistry and Physics. In this paper we present a new parameterization of the reactive uptake of glyoxal and methylglyoxal by atmospheric aerosols and cloud droplets. Our calculations take into account newly available information regarding the gas-particle partitioning of these species and their chemical processing in the aerosol phase. The particle and droplet types considered were based on definitions in GEOS-Chem v11, but the approach is general. We expect application of these parameterizations will result in improved representation of aqueous secondary organic aerosol formation in atmospheric chemistry models.
