When is air pollution at its worst in El Sardinero?
What time of year has the cleanest air in El Sardinero? Winter high-pressure systems tend to produce the year's worst episodes, as still air traps traffic fumes and heating smoke at ground level. March through May tends to see steady improvement, with more unsettled weather patterns helping disperse traffic and heating pollution. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. This region's wetter, windier Atlantic climate generally keeps annual air quality more consistent than in Spain's drier interior and south.
Are air quality levels in El Sardinero 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.
