Worst air pollution Lock Haven, today and tomorrow

On 9 August 2026, overall air quality in Lock Haven is fair. O3 is the main pollutant at 35.1/100. Pollution peaks around 11:00 PM (NO2: 40.1/100).

On 10 August 2026, air quality conditions in Lock Haven will be similar to today, with O3 forecast at fair at 32.4/100. Pollution peaks around 1:00 AM (NO2: 50.8/100).

Air quality across Lock Haven rises and falls with the seasons — a mild stretch in early spring often brings some of the year's better air, before summer ozone builds, whereas summer heat waves bring the highest ozone risk, compounded by pollution drifting in from the wider region. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.

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.

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.
