When is air pollution at its worst in Riazor?
Does air quality in Riazor vary by season? The year's lowest air quality readings tend to cluster in winter, when high-pressure systems suppress the mixing that would otherwise clear away exhaust and smoke. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer's intense heat and sunshine create ideal conditions for ozone formation, sometimes overshadowing the lower traffic volumes typical of the season. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. 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 Riazor 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.
