This parameterization generally follows the Bertram and Thornton ACP (2009) functional form for SNA aerosol (excluding chloride enhancement) and treats aerosol organics as a resistive coating.

Parameters in the gamma expression are fitted to aircraft observations. N2O5 uptake on sulfate-nitrate-ammonium-organic aerosol is calculated with gamma for combined SNA+ORG aerosol in in which a SNA core is coated with an organic shell (McDuffie et al. The changes in the cloud and ice surface areas had significant impact on the cycling of HCl to ClOx species increasing them in the UT. Losses of NO3 and N2O5 in clouds are currently included and the method and code can also be applied to other species that react in clouds. This method accounts for cloud fraction and entrainment within the chemical loss rates. Entrainment-limited uptake in clouds, as defined by Holmes et al. The effective radius and surface area of ice cloud particles have been updated based on aircraft observations (Heymsfield et al., 2014). These changes are described by Holmes et al. This combines model updates described by Holmes et al. This update was included in GEOS-Chem 12.6.0, which was released on.
