Abstract
The work studies the influence of tree height on aerodynamics and passive gaseous pollutant transport in a three-dimensional street canyon. The calculations were performed using the Large Eddy Simulation (LES) model of turbulent flow with explicit parameterization of vegetation. The integral characteristics of the pollutant concentration in a street canyon in total and in a breathing zone (up to 2 m from the bottom of a canyon) were calculated and analyzed. The results show that the use of long hedges of varying heights in an urban environment can lead to deterioration of air circulation in the street canyons. These results will help to more accurately solve problems in the case of denser development and greening of urban spaces.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
