When is air pollution at its worst in Breite?

Calm winter weather is when Breite's air quality suffers most, with vehicle traffic and cross-border industry settling over the plain instead of dispersing as they normally would. Warmer months bring noticeably better airflow across this flat terrain, with only the occasional summer ozone spike breaking an otherwise clean pattern through spring and autumn.

Are air quality levels in Breite 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.
