Manresa's air quality reflects the Cardoner-Llobregat river valley in the Barcelona metropolitan area's inland industrial corridor, with vehicle traffic on the C-55 and surrounding salt mining, manufacturing, and logistics operations contributing local sources. The surrounding Montserrat massif and the Bages highland ridgelines create topographic enclosure, while the valley floor concentrates emissions under calm winter conditions and Barcelona's metropolitan sea breeze provides afternoon ventilation.

When is air pollution at its worst in Manresa?
What time of year has the cleanest air in Manresa? Air quality often reaches its yearly low in the depths of winter, when still, cold air holds local emissions from traffic and heating close to ground level. By spring, air quality usually starts trending upward as the calm winter inversions give way to more unsettled, breezier weather. During summer, strong sunlight and high temperatures accelerate ozone formation, occasionally offsetting the drop in traffic and heating-related emissions. The transition into autumn generally brings cleaner conditions, as more frequent rainfall and lower temperatures curb ozone formation. Being on the Mediterranean coast helps with dispersal most of the year, though summer tourism and North African dust episodes remain a factor.
Are air quality levels in Manresa 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.
