Air pollution is becoming an important environmental issue and attracting increasing public attention, especially in urban environments where it is affected by a large variety of factors (like road type, urban architecture, land use and variety of emission sources) and changes very dynamically, both with time and space. In order to better understand the complexity of urban air pollution, hyperlocal air pollution monitoring is necessary, but the existing regulatory monitoring networks are typically sparse due to the high costs to cover a full city area at the necessary level of detail (spatial granularity). In this paper, we use the city of Antwerp in Belgium as a pilot to analyze the temporal and spatial distribution of four atmospheric pollutants (NO2, PM1, PM2.5 and PM10 ) at street level by using mobile air pollution monitoring. In particular, we explore how the atmospheric pollutant concentration is affected by different context factors (e.g., road type, land use, source proximity). Our results demonstrate that these factors have an impact on the concentration distribution of the considered pollutants. For example, higher atmospheric NO 2 concentrations are observed on primary roads, compared to secondary roads, and some source locations such as traffic lights have shown to be hot spots of atmospheric NO 2 accumulation. These findings can be useful in order to formulate future local air quality measures and further improve current air quality models based on the observed impact of the considered context factors.
