Parameterization of pollutant plume dispersion in neutral stratification over hypothetical urban areas

Nowadays, people are more aware of the air quality than ever. Ground-level pollutants from human activities and vehicles are the primary pollutant sources, which adversely affect the health and living quality of urban inhabitants. Therefore, a simple and reliable air pollutant dispersion model is necessary to estimate concentration distribution and evaluate pollutant problems. The Gaussian model of plume dispersion, which is one of the earliest atmospheric dispersion models developed, is still commonly used to estimate the downwind pollutant concentration distribution. Dispersion coefficients (σz), or the standard deviation of vertical pollutant concentration distribution, is ...published_or_final_versio
