When is air pollution at its worst in Casco Viejo (Pamplona)?
Does air quality in Casco Viejo (Pamplona) vary by season? Air quality often reaches its yearly low in the depths of winter, when still, cold air holds local emissions from traffic and heating close to ground level. Air quality usually improves through spring, helped by more frequent frontal systems that bring rain and stronger winds to disperse local emissions. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. Conditions tend to stabilise in autumn, as cooling weather and increasing rain reduce the ozone spikes typical of summer. 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 Casco Viejo (Pamplona) 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.
