When is air pollution at its worst in Alcázar de San Juan?
What is the yearly air quality pattern like in Alcázar de San Juan? January is frequently the most difficult month, with cold stagnant air allowing wood-smoke and exhaust to build up instead of clearing. Spring is typically a transitional season, as milder, windier weather starts clearing out the pollutants that accumulate during winter's calm spells. High summer temperatures and strong sun exposure drive ozone levels up, occasionally combined with smoke from nearby wildfires during dry spells. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. The continental interior's hot, dry summers and cold, still winters make it prone to sharper seasonal swings than coastal Spain.
Are air quality levels in Alcázar de San Juan 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.
