This dataset contains air quality measurements made available by Airparif from reference monitoring stations and fixed and mobile low-cost sensors in the Paris region. The data correspond to February 19, 2021, between 08:00 and 09:00, and include measurements of PM2.5 and PM10. The dataset contains spatial coordinates in Lambert-93, measurement time intervals and mass concentrations (µg/m³). Reference-station measurements additionally include an estimate of aleatoric measurement uncertainty. A detailed description of the files and variables is provided in the accompanying README.
