What time of year has the cleanest air in Barañáin? Cold, windless spells in December and January are usually when conditions dip most, as heating emissions and traffic fumes accumulate under a stable atmosphere. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer heat and intense sunlight drive photochemical ozone production, which can push afternoon air quality readings higher despite reduced winter-style pollution sources. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. The Atlantic north's frequent rain and strong onshore winds generally keep year-round levels lower than in the drier interior and south.

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.
