Air pollution is known to be a major threat to human and ecosystem health. A proper understanding of the factors generating pollution and of the behavior of air pollution in time is crucial to support the development of effective policies aiming at the reduction of pollutant concentration. This paper considers the hourly time series of three pollutants, namely NO, O and PM2.5, collected on sixteen measurement stations in Switzerland. The air pollution patterns due to the location of measurement stations and their relationship with anthropogenic activities, and specifically land use, are studied using two approaches: Fisher–Shannon information plane and complexity-invariant distance between time series. Clustering analysis is used to recognize within the measurements of same pollutant groups of stations behaving in a similar way. The results clearly demonstrate the relationship between air pollution probability densities and land use activities.

Abstract
Air pollution is known to be a major threat to human and ecosystem health. A proper understanding of the factors generating pollution and of the behavior of air pollution in time is crucial to support the development of effective policies aiming at the reduction of pollutant concentration. This paper considers the hourly time series of three pollutants, namely NO, O and PM2.5, collected on sixteen measurement stations in Switzerland. The air pollution patterns due to the location of measurement stations and their relationship with anthropogenic activities, and specifically land use, are studied using two approaches: Fisher–Shannon information plane and complexity-invariant distance between time series. Clustering analysis is used to recognize within the measurements of same pollutant groups of stations behaving in a similar way. The results clearly demonstrate the relationship between air pollution probability densities and land use activities.File | Dimensione | Formato | |
