Case Studies: Modeling the Atmospheric Benefits of Urban Greening

Urban green infrastructure (UGI ) holds the potential to mitigate increasing temperatures as a result of climate change, and vegetation can contribute to urban air quality through air pollution mitigation (Nowak et al. 2006). Along with these environmental benefits, however, the presence of vegetation can have unwanted and unexpected effects on local air quality, for example through the emission of biogenic volatile organic compounds (BVOCs ) that can act as precursors of secondary air pollutants (Nowak et al. 2000).
These processes are all influenced by the nature of air circulation within the urban area, and it has been shown in field campaigns (Kikuchi et al. 2007), wind-tunnel experiments (Gromke and Ruck 2009) and numerical modelling (Mochida et al. 2008; Buccolieri et al. 2009), that the complexity of wind flow in a given urban space is significantly increased in the presence of urban vegetation.
The interactions of UGI with its environment are a consequence of...
