In Pontarlier, light industry and river-valley traffic is the primary local source affecting air quality, near the Doubs, though the Saone and Doubs valleys channel airflow, which usually keeps pollution from accumulating for long. The coldest winter days bring the worst conditions, with heating and traffic emissions trapped in the valleys, whereas summer generally offers cleaner air aside from the odd ozone spike during heatwaves.

Is air quality bad in Pontarlier right now?
On 25 August 2026, overall air quality in Pontarlier is moderate. AQI is the main air quality indicator at 52.0/100. Pollution peaks around 11:00 PM (NO2: 52.0/100).
Will air quality be worse tomorrow in Pontarlier?
On 26 August 2026, air quality conditions in Pontarlier will be similar to today, with AQI forecast at moderate at 59.2/100. Pollution peaks around 1:00 AM (NO2: 59.2/100).
When is air pollution at its worst in Pontarlier?
In Pontarlier, allergy sufferers and those sensitive to pollution both notice more symptoms when light industry and river-valley traffic coincides with heavy oak and hornbeam pollen; the Saone and Doubs valleys channel airflow, keeping bad spells relatively short.
Are air quality levels in Pontarlier 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.
