In New Brighton State Beach Campground, with less congestion here, dust from surrounding fields and occasional burning plays a bigger role than traffic. This is partly offset by nearby tree cover, which filters out some particulate matter naturally. This general baseline tends to hold across nearby areas with similar traffic and land use.

When is air pollution at its worst in New Brighton State Beach Campground?
From December to February, average wind speeds run around 9 km/h with temperatures near 10°C, calm and cool enough to let particulate matter and smoke build up near the ground rather than disperse. From July to September, temperatures average around 18°C, warm enough for strong sun and heat to drive ground-level ozone formation.
Are air quality levels in New Brighton State Beach Campground 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.
