When is air pollution at its worst in Simmering?
Winter is when Simmering sees its worst air quality, as vehicle traffic and residential heating across the city settle under a basin inversion on calm, cold mornings. Things pick up through spring, and summer's stronger winds keep the air generally clear despite occasional hot-weather ozone peaks. Autumn tends to be another comparatively steady stretch across the city.
Are air quality levels in Simmering 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.
