Monitoring of air pollutants using a stratospheric balloon

Air pollution is an increasingly debated and relevant topic; recent natural disasters define the need to study and intervene for environmental protection. To date, atmospheric studies are mainly satellite-based and static at ground level. O-Zone Team was set up based on this state of the art to encourage technological development regarding dynamic sampling analysis. This paper introduces the O-Zone experiment and describes the system employed in pollutants detection; details are provided on sensors metrology and samples analysis.
