In Moundsville, humid Ohio River Valley air is the main influence on air quality, and river-valley humidity can hold summer haze close to the ground. These factors combine to give Moundsville a fairly typical seasonal air quality pattern for this part of the country. None of this replaces checking the current forecast before heading outdoors in Moundsville.

When is air pollution at its worst in Moundsville?
Seasonal changes shape air quality across Moundsville. In short, mild winter weather usually brings the year's cleanest air, whereas an extended run of hot, humid afternoons in summer is when ozone most often climbs into unhealthy territory. Prescribed burns are more common in the cooler months and can add brief smoke episodes.
Are air quality levels in Moundsville 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.
