NC's ozone season occurs in the peak of NC's growing season. This region possesses a large number of trees and agricultural fields/crops. The fluxes of heat and moisture are affected by the spatial variations of surface vegetation and therefore also influence the local concentration of ozone. In order to complete a detailed analysis of the surface effects on ozone, one must first have a detailed representation of the surface. During this research it has been seen that several lakes/ponds, roads, and elevations have not been truly depicted in the most current available data. This study will include a detailed surface analysis and a detailed analysis of the surface fluxes in order to better characterize ozone episodes in Greensboro, NC.
North Carolina has thirteen international or major regional airports. It also has the largest state maintained highway network in the United States. The city is at the nexus of several major freeways. With such a profound transportation network the amount of emissions can reach exorbitant rates over certain times of the day. These emissions have a considerable effect on the development of ozone. The WRF-Chem model will be used to investigate the chemistry of ozone production and depletion. This study will attempt to quantify the pattern of emission of ozone precursors using available traffic data and examine its relationship with ozone episodes.
The overall goal of this research is to better the understanding of atmospheric composition, structure, function, and variability in order to improve on the development of more robust modeling. The models used in this research, WRF, WRF-Chem and NOAA's PBL algorithm, will be tested on their reliability and accuracy by comparing their results with available observational data. This will aid in establishing the framework and strategies required to meet society's evolving needs. The scope of this research is to examine what factors, human or otherwise, influence atmospheric processes and constituents, particularly ozone.
