How do the seasons affect air quality in Teatro Romano de Mérida? December through February is often the toughest stretch, driven by temperature inversions that keep exhaust and heating smoke from dispersing on still days. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer brings its own challenge in the form of ground-level ozone, which forms readily under strong sunshine and high temperatures, particularly during heatwaves. Early autumn can still bring warm, stagnant spells before the season's returning rain and wind begin clearing the air. The interior's dry continental climate means winter inversions and summer heat both tend to hit harder than along the coast.

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.
