Amara's dominant local factors are local traffic and damp-weather heating smoke in winter. Air quality is generally very good thanks to frequent rain and constant Atlantic wind. Frequent rain washes pollutants out of the air more often than in drier parts of Spain.

When is air pollution at its worst in Amara?

What time of year has the cleanest air in Amara? Air quality is typically at its weakest in December and January, when cold, calm high-pressure spells trap traffic exhaust and wood-smoke close to the ground instead of letting it disperse. Conditions tend to ease in spring, as more active weather systems bring the wind and rain needed to disperse ground-level pollution. Summer heat and intense sunlight drive photochemical ozone production, which can push afternoon air quality readings higher despite reduced winter-style pollution sources. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. Proximity to the Atlantic brings enough rain and wind through most of the year to limit how long pollution episodes last here.

Are air quality levels in Amara 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.
