The contribution of transport and chemical processes on coastal ozone and emission control strategies to reduce ozone.

ABSTRACT: The interaction between transport and chemistry is pivotal for local ozone (O₃) concentration, especially for a coastal region where the upstream sources might change diurnally. In the current emission control policy, most pollutants, such as particulate matter, SO₂, NOx, and CO, decrease while the annual O₃ trend might increase due to the complex feedbacks of precursors. In this study, we investigate the influence of transport upon the wintertime O₃ diurnal trend over ZuoYing Kaohsiung, an urban coastal site in southern Taiwan, by constructing a two-dimensional numerical model coupling both physical mechanisms and core chemical processes and provide a feasible emission control strategy. The transport process (i.e., import vs. export) for the day
