When is air pollution at its worst in El Fontán?
How does air quality change throughout the year in El Fontán? Winter tends to bring the year's weakest readings, as stagnant, cold air lets heating smoke and vehicle emissions build up rather than clear away. Spring usually brings an improvement as more frequent rain and stronger winds help clear the air and wash out pollutants that built up over winter. High summer temperatures and strong sun exposure drive ozone levels up, occasionally combined with smoke from nearby wildfires during dry spells. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. Being close to the Atlantic, this area benefits from regular rainfall and wind that help keep pollution from building up for long.
Are air quality levels in El Fontán 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.
