Clouds and aerosols impact on climate, both independently and through their interaction with one another. Thus, in climate models, it is important to make cloud schemes and in-cloud chemistry as realistic as possible. To this end, the UQAM sub-grid scale cloud scheme was added to LCM11, a one-dimensional version of the Northern Aerosol Regional Climate Model (NARCM). The goal of this project is to assess whether it is necessary to complete parameterization of sub-grid scale processes in LCM11 by implementing sub-grid scale parcel chemistry. / Parallel runs of LCM 11 with and without parcel chemistry were performed under various chemical scenarios. The production of sulphate, the main anthropogenic constituent of tropospheric aerosols, was compared within parallel runs. Sulphate production was not significantly changed by the implementation of parcel chemistry. Thus, for the scenarios assayed in this project, the addition of sub-grid scale parcel chemistry to LCM11 is deemed unnecessary.
