When is air pollution at its worst in Casco Vello?
How does air quality change throughout the year in Casco Vello? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. March through May tends to see steady improvement, with more unsettled weather patterns helping disperse traffic and heating pollution. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. The Atlantic north's frequent rain and strong onshore winds generally keep year-round levels lower than in the drier interior and south.
Are air quality levels in Casco Vello 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.
