When is air pollution at its worst in Mett?

Calm winter conditions are when Mett's air quality suffers most, with vehicle traffic and administrative and commuter activity settling into the valley instead of clearing with the wind as usual. Warmer months bring noticeably better airflow through the valley, with only the occasional summer ozone spike breaking an otherwise clean pattern through spring and autumn.

Are air quality levels in Mett 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.
