When is air pollution at its worst in George Rogers Clark National Historical Park?
George Rogers Clark National Historical Park follows Vincennes's typical seasonal air quality pattern, as between summer ozone and occasional winter inversions, spring and fall are the year's cleanest stretch; by contrast, the peak of summer, when heat and humidity linger for days, is when air quality most often suffers. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.
Are air quality levels in George Rogers Clark National Historical Park 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.
