Environmental impact markers

One of Unical's activities consists in constructing environmental impact markers, starting from a preliminary analysis of data and integrating these with information from different sources.

The activity was therefore focused on the study and application of spatial interpolation methods, with the aim of obtaining estimates of pollutants at unattended points from point measurements of pollutant concentrations available at monitored sites. In particular, the use of methods based on so-called kriging was considered. In parallel, the study of models known as LUR (Land Use Regression models) was carried out. 

This approach combines information from air pollution measurements at a limited number of locations and data from geographical information systems (GIS) through the construction of regression-type statistical models.
