In Pedralbes, road traffic and construction dust drive most of the variation in air quality. Air quality is generally worse near the port and main traffic corridors. Shipping traffic through the port is a significant and distinctive local source.

When is air pollution at its worst in Pedralbes?
What time of year has the cleanest air in Pedralbes? The winter months typically bring the weakest air quality of the year, as calm anticyclonic conditions trap vehicle and heating pollution near the surface. The transition into spring usually brings cleaner air, as more frequent rain and wind reduce the buildup of local pollution. Summer heat and intense sunlight drive photochemical ozone production, which can push afternoon air quality readings higher despite reduced winter-style pollution sources. Early autumn can still bring warm, stagnant spells before the season's returning rain and wind begin clearing the air. This Mediterranean location benefits from regular sea breezes, though summer's higher traffic volumes and occasional Saharan dust events can offset that.
Are air quality levels in Pedralbes 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.
