When is air pollution at its worst in Antiguo?
When is air quality typically worst in Antiguo? The year's lowest air quality readings tend to cluster in winter, when high-pressure systems suppress the mixing that would otherwise clear away exhaust and smoke. Conditions generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. Being close to the Atlantic, this area benefits from regular rainfall and wind that help keep pollution from building up for long.
Are air quality levels in Antiguo 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.
