Worst air pollution El Sadar - Pamplona, today and tomorrow

On 9 August 2026, overall air quality in El Sadar is fair. AQI is the main air quality indicator at 33.2/100. Pollution peaks around 1:00 PM (O3: 33.2/100).

On 10 August 2026, air quality conditions in El Sadar will be similar to today, with AQI forecast at fair at 31.0/100. Pollution peaks around 7:00 PM (O3: 31.0/100).

What is the yearly air quality pattern like in El Sadar? Winter high-pressure systems tend to produce the year's worst episodes, as still air traps traffic fumes and heating smoke at ground level. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer heat and intense sunlight drive photochemical ozone production, which can push afternoon air quality readings higher despite reduced winter-style pollution sources. Autumn generally marks the shift back toward calmer, cleaner conditions as temperatures drop and rainfall becomes more regular. The Atlantic north's frequent rain and strong onshore winds generally keep year-round levels lower than in the drier interior and south.

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.
