Air quality and haze in Beijing's urban environment
Lead Research Organisation:
University of Edinburgh
Department Name: Sch of Geosciences
Abstract
High levels of particulate matter associated with urban and industrial emission sources lead to the formation of pollutant haze in many urban areas, notably Beijing. Dense haze reduces surface heating and photolysis rates, affecting boundary layer structure and surface air quality. The aim of this project is to use the ADMS-Urban model to explore how air quality in Beijing's urban environment is impacted by haze, including haze-urban heat island interactions.

| Description | I have set-up and developed a street-scale urban air quality model for Beijing. This has included acquiring and processing the necessary input meteorological data, calculating pollutant species background concentrations from measurements and creating an explicit source road emissions network. Developing the road traffic emissions inventory required apportioning 3km gridded emissions onto a spatial road map (OpenStreetMap). Future applications of ADMS-Urban for Beijing would significantly benefit from: (a) The prior development of a comprehensive bottom-up road emissions inventory based on real-world vehicle activity data (traffic volume, fleet, restrictions etc.) and emission factors (b) Use of the ADMS-Urban Regional Model Link, with the coupled regional-scale chemistry transport model providing a more representative spatially varying background concentration field (c) A detailed buildings geometry dataset: information on building heights/widths and street canyon widths would enable the use of the Urban Canopy Module (or if more detailed information is gathered, the Advanced Street Canyon Module) perturbing the vertical wind speed/direction and turbulence profiles to create a spatially inhomogeneous flow field. |
