TL;DR: In this article, the effect of barrier height on air pollution in neutral, stable, and unstable conditions is investigated. And the authors illustrate an application of these models by estimating the effect that barrier height has on concentrations during neutral and stable conditions.

TL;DR: In this article, the authors analyzed three data sets to examine methods to estimate the height of the stable boundary layer (SBL) in the complex setting of an urban area, focusing on a data set from a field study that they conducted in Riverside, California, in 2011 in which surface micrometeorological variables were measured using a sonic anemometer.

TL;DR: In this article, semi-empirical dispersion models based on data from controlled wind tunnel and tracer experiments can describe data collected downwind of a sound barrier next to a real-world urban highway.

TL;DR: In this article, the authors used a model that assumes that vertical turbulent transport of emissions dominates the governing processes and showed that magnification of concentrations relative to those in the absence of buildings is most sensitive to the aspect ratio of the street.

TL;DR: A Lagrangian model is formulated to supplement comprehensive Eulerian grid models such as CMAQ, to estimate concentrations of NO"x, NO"2, and O"3 averaged over a spatial scale of the order of a kilometer over a domain extending over hundreds of kilometers.
