Objective:
1) Develop mechanistic/kinetic data needed to simulate in-cloud formation of secondary organic aerosol (SOA) in the presence of HNO3, 2) identify conditions for which predicted in-cloud SOA formed from isoprene decreases with reductions in interstitial concentrations of ·OH and HNO3 (atmospheric oxidants with anthropogenic precursors), and 3) incorporate an in-cloud SOA formation pathway into the Community Multiscale Air Quality (CMAQ) model and explore the magnitude of in-cloud SOA formation through a limited set of model simulations.
