Description:
Ambient air quality has traditionally been monitored using a network of fixed point sampling sites that are strategically placed to represent regional (e.g., county or town) rather than local (e.g., neighborhood) air quality trends. This type of monitoring data has been used to make linkages between air quality and health endpoints, understand atmospheric processes, and validate regional air quality modeling. However, recent studies focusing on near-road air quality have shown that ambient air concentrations and linked health outcomes can fluctuate at neighborhood-sized spatial scales in the proximity of a major roadway. These findings point to the need to quantify local scale ambient air quality concentrations and spatial variability.
