In Crown Point, occasional vehicle traffic and open farmland nearby mean particulate matter here comes more from dust and seasonal field work than congestion. Green space nearby, at about 300-400 meters, offers a partial natural check on particulate buildup. Actual air quality on a given day still depends heavily on local wind and weather conditions.

When is air pollution at its worst in Crown Point?
Winter is usually when particulate matter climbs highest locally, when home heating emissions build up under temperature inversions common on calm winter days. Once summer sets in, ground-level ozone becomes the bigger local concern, with summer's heat and sunlight together producing some of the year's highest local ozone levels. The transitional months of spring and fall typically see the year's lowest particulate and ozone levels.
Are air quality levels in Crown Point 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
