Description:

This project addresses the question of how boundary-layer processes influence ozone production, biogenic hydrocarbon oxidation rates, and the atmospheric distribution of biogenic hydrocarbons and their oxidation by-products. The processes to be investigated include cumulus venting of boundary-layer air, forest canopy venting, heterogeneous source distributions of biogenic hydrocarbons, and gas-phase and aqueous-phase chemistry. These processes will be studied with a boundary-layer large-eddy simulation (LES) model that incorporates a rigorous gas and aqueous-phase hydrocarbon chemical mechanism, and a boundary-layer LES that includes a nested forest-canopy LES. The project will attempt to distill the results of these microscale simulations into one-dimensional, convective-layer scaling formulations which could be expanded into parameterizations for larger-scale models.
