The cloud chemistry session will focus both on gas-aqueous chemistry without aerosols and on aqueous chemistry as it affects aerosols. This study will be performed in 3 parts, where the first two are box model simulations. Part 1. A box model simulation. This simulation has the purpose of assessing numerical approximation solver techniques of the gas-aqueous chemical system. We will also discuss the effect of the cloud chemistry on the gas-phase species. Part 2. A box model simulation. Simulations of aqueous-phase sulfur chemistry are used to examine the pH of the cloud drops and to contrast the results of models describing monodisperse aerosol particles and cloud drops with those describing polydisperse aerosol particles and cloud drops. Part 3. A cloud scale simulation. Simulations of stratocumulus observed in the Gulf of Maine during the NARE 1993 field campaign will be conducted. The model results will be compared with interstitial and cloud water chemical species observations.
