Reference PM2.5 and wind data for Oshawa and Allen Road

This dataset includes reference data used in the creation of the article titled “Localized Variabilities in Traffic-related Air Pollutant Concentrations Revealed Using Compact Sensor Networks”. This dataset accompanies the original dataset named “TRAP and traffic data for Oshawa and Allen Road” (doi: 10.17632/y9yypy582j.1). The objectives of the study, its observational data, findings, and implications are discussed in that dataset’s description. Included in this reference dataset is hourly averaged reference PM2.5 data from the Oshawa ambient air quality monitoring station operated by the Ontario Ministry of Environment, Conservation, and Parks (MECP) and located at (43.9522, -78.9125). This data was used as a comparison to validate AirSENCE PM2.5 data and help explain the observed trends. Also contained in this dataset is 10-minute averaged windspeed and wind direction data obtained from Downsview ambient air monitoring station, also operated by MECP, located at (43.7805, -79.4674). This data was used to categorize the TRAP data measured by AirSENCE at Allen Road in Toronto with regards to wind conditions and ascertain its impacts on TRAP dispersion. The main article provides details on how the wind data was processed and utilized.
