Abstract
Population exposure to atmospheric pollution is commonly assessed through models. This study aims to compare estimates based on a high-resolution model and actual measurements. The considered modelling system, ATMO-Street, consists of a three-layer outdoor model operating at an hourly rate with a spatial resolution of approximately 10 m. The considered measurements were made by 38 candidate citizens carrying, for 1 week, portable devices, including an AE51 aethalometer and an Antilope low-cost sensor system developed at the Scientific Institute of Public Service (ISSeP). Their data were aggregated to match the model time and space resolutions. The zone of interest is the city of Liège in Belgium during parts of the year 2019. This research sheds light on the effectiveness of the atmospheric pollution model and personal exposure assessment methods. The findings contribute to a somewhat more comprehensive understanding of our exposure to air pollution, including indoors, with potential implications for public health and environmental policy.
