Warmer months bring noticeably better airflow through this part of eastern Switzerland, with only the occasional summer ozone spike breaking an otherwise clean pattern.
Are air quality levels in Frauenfeld based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
