Résumé

Public perception and concern have raised the interest for operational air quality systems at urban scales with enough resolution to provide an accurate assessment of human exposure to air pollution. In this sense, the recent developments in concentration micro sensors make them an attractive alternative to expand urban air monitoring networks thanks to their low cost and easy set-up. Their integration to atmospheric dispersion models can be achieved by using various types of assimilation techniques. In response to this, the FAIRCITY project aims to develop both aspects: the performance of a high-resolution dispersion model and the use of the observations from a micro sensors network, to produce a “real time” air quality platform. We present the outcome of the experience developed in the city of Paris focused on the deployment of a high-resolution air quality system along with a mobile sensor network. The product included a 3m resolution air quality index map produced by the PMSS model and the visualization of observations from 20 mobile multipollutant micro sensors in “near real-time”. Furthermore, current developments in the understanding of micro sensors’ representativeness and assimilation techniques are also presented. © 2019 Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes, HARMO.
