How do the seasons affect air quality in Guadalajara? 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 generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. Being inland, this area sees more extreme summer heat and winter cold, which sharpens the seasonal contrast in air quality.

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.
