What is the yearly air quality pattern like in Jerez de la Frontera? 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 is typically when conditions begin improving, as increasing wind speeds help disperse traffic emissions before they can accumulate. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. Southern Spain's intense summer heat and periodic Saharan dust intrusions add extra pressure on top of the usual seasonal pattern.

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.
