Evaluating the impact of evolving green and grey urban infrastructure on local particulate pollution around city square parks.

ABSTRACT: The relationship between green and grey urban infrastructure, local meteorological conditions, and traffic-related air pollution is complex and dynamic. This case study examined the effect of evolving morphologies around a city square park in Dublin and explores the twin impacts of local urban development (grey) and maturing parks (green) on particulate matter (PM) pollution. A fixed air quality monitoring campaign and computational fluid dynamic modelling (ENVI-met) were used to assess current (baseline) and future scenarios. The baseline results presented the distribution of PM in the study area, with bimodal (PM_2.5) and unimodal (PM₁₀) diurnal profiles. The optimal vegetation height for air quality within the park also differed by wind direction with 21 m vegetatio
