D. GIS data conflation program that achieves 97% automatic match rate routinely
Additive models depicting the effects of traffic, distance to nearest source, wind speed, temperature, and RH were created for each of the pollutants studied to assess the impacts of both the BQE and the WB simultaneously. Although wind direction would have a clear effect on concentrations in principle, our sampling occurred almost exclusively in low wind-speed conditions with variable wind directions, which can potentially lead to a spreading of the aerosol plume in multiple directions, including upwind ( Hanna et al. 2003 ). We therefore constructed our primary models without a wind-direction term but considered the implications of this omission in our sensitivity analyses.
