This project, based in one of the world's only stratified atmospheric boundary layer simulating wind-tunnels, will study the complex relationships between temperature, turbulence and transport within the built environment using some of the world's most sophisticated instrumentation. To date, there has been very little work done to comprehensively include the effects of temperature in the study of turbulence and air quality within the urban canopy layer.In particular, this project is aimed at improving dispersion and air quality models, in order to better understand the mechanisms by which contaminants (like vehicle exhaust) distributes along street canyons when driven by both the incident wind and the effects of thermal buoyancy.

该项目以世界上唯一的模拟风洞的分层大气边界层之一为基础，将使用一些世界上最先进的仪器来研究建筑环境中温度、湍流和运输之间的复杂关系。迄今为止，在城市冠层内的湍流和空气质量研究中综合考虑温度影响的工作还很少。特别是，该项目旨在改进扩散和空气质量模型，以便更好地研究城市冠层内的湍流和空气质量。了解污染物（如汽车尾气）在迎风和热浮力影响下沿着街道峡谷分布的机制。
