Local Environmental Conditions
The center of Kallithéa is largely built up, so vehicle exhaust and urban activity dominate the local air pollution sources. Lying in a basin, the area is prone to temperature inversions that hold pollutants near the ground when winds drop. Sea breezes along the coast usually help ventilate the area. Port and shipping activity adds to local emissions. On some days, pollution drifting in from farther away outweighs local sources.
Even in the mild winter months, January to March, at around 10°C, calm nights let traffic pollution settle in the basin. Ozone is the main concern from May to September, when sunny days averaging 29°C turn traffic and other emissions into ozone by mid-afternoon. January is usually the windiest month, averaging about 20 km/h, which helps keep the air clean.

When is air pollution at its worst in Kallithéa?
Even in the mild winter months, January to March, at around 10°C, calm nights let traffic pollution settle in the basin. Ozone is the main concern from May to September, when sunny days averaging 29°C turn traffic and other emissions into ozone by mid-afternoon. January is usually the windiest month, averaging about 20 km/h, which helps keep the air clean.
Are air quality levels in Kallithéa 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
