When is air pollution at its worst in Casco Antiguo (Salamanca)?
Does air quality in Casco Antiguo (Salamanca) vary by season? Winter high-pressure systems tend to produce the year's worst episodes, as still air traps traffic fumes and heating smoke at ground level. 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. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. The interior's dry continental climate means winter inversions and summer heat both tend to hit harder than along the coast.
Are air quality levels in Casco Antiguo (Salamanca) 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.
