Pamplona's air quality reflects its position in the enclosed Pamplona basin surrounded by the pre-Pyrenean sierras and the Navarra foothills, with vehicle traffic on the A-15 and the surrounding industrial and food processing corridor contributing local sources. The Tramontane wind from the north provides powerful periodic ventilation, while winter temperature inversions in the basin and the Arga river valley can concentrate vehicle and heating emissions, creating the seasonal air quality variation typical of enclosed Iberian plateau basins.

When is air pollution at its worst in Pamplona?
How does air quality change throughout the year in Pamplona? January is frequently the most difficult month, with cold stagnant air allowing wood-smoke and exhaust to build up instead of clearing. Conditions generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. Frequent Atlantic weather systems mean pollution rarely has the chance to accumulate for long stretches in this area.
Are air quality levels in Pamplona 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.
