Local air quality in Extramurs depends heavily on local traffic squeezed into narrow streets and seasonal heating smoke in winter. Air quality is generally moderate, dictated mostly by how much traffic reaches the old core. Pedestrianised zones in many old centres have measurably reduced local traffic pollution.

When is air pollution at its worst in Extramurs?

How does air quality change throughout the year in Extramurs? 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. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. The mild, breezy Mediterranean climate generally supports good dispersal, though summer crowds and Saharan dust intrusions can occasionally push levels higher.

Are air quality levels in Extramurs 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.
