When is air pollution at its worst in Cape May?

Cape May follows a fairly predictable seasonal air quality pattern — the calmest air of the year usually arrives well after the summer ozone season fades, whereas extended summer heat waves, often worsened by regional haze, bring the toughest air quality stretch. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.

Are air quality levels in Cape May 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.
