When is air pollution at its worst in Arnedo?
What time of year has the cleanest air in Arnedo? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. Spring often marks a turning point, with increasing storminess and rainfall helping to clear accumulated exhaust and smoke from the air. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. The transition into autumn generally brings cleaner conditions, as more frequent rainfall and lower temperatures curb ozone formation. 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 Arnedo 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.
