This dataset provides high-resolution, 10-minute particulate matter (PM1, PM2.5, and PM10) measurements collected to identify and analyze traffic-induced air pollution. The data were acquired using two enviDUST air quality monitoring sensors mounted on a mobile measurement vehicle located near an intersection. To effectively capture the spatial variance and directional effects of pollutant dispersion, the devices were installed in distinct orientations, as detailed in the attached image. The measurement campaign ran continuously over the summer months of July and August 2025. The final dataset consists of two separate data files, corresponding to the respective enviDUST devices.
