Peristeri's air quality reflects its position in the densely urbanised western Athens metropolitan area, with the Attiki Odos ring road and the A1 national road generating concentrated vehicle emissions alongside the dense residential and commercial character of one of Greece's most populated municipalities. The Attica basin's enclosed position between Hymettus, Pendeli, and Parnes concentrates all emissions under the persistent Athenian temperature inversions, and Peristeri's urban density keeps readings consistently among the higher values in the broader Athens metropolitan area.

When is air pollution at its worst in Peristéri?
The most noticeable dips in Peristéri's air quality come when pine and cypress pollen peaks, or because of the Attiki Odos ring road and the A1 national road; the remainder of the year typically brings clearer, more consistent conditions.
Are air quality levels in Peristéri 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.
