Abstract

International audience The characterisation and the precise measurements of the atmospheric concentration of pollutants are essential to improve the understanding and the modelling of urban air pollution processes. The QualAir platform at the Université Pierre et Marie Curie (UPMC) is an experimental research platform dedicated to urban air quality and pollution studies. As one of the major instruments of this station, the ground-based Fourier transform spectrometer (QualAir FTS) is providing information on the air composition of a megacity like Paris. Operating in solar infrared absorption, it enables to monitor several important pollutants involved in tropospheric chemistry and atmospheric transport around the Ile de France region. Results on nitrous oxide (N2O), methane (CH4) and carbon monoxide (CO) will be presented in this paper as well as the comparison with satellite and in situ measurements showing the capabilities and strengths of this ground-based FTS and of some of the other instruments of the QualAir platform.
