Local Environmental Conditions
Around the center of Santa Venetia, traffic is light and there are few concentrated sources of air pollution. Breezes off the nearby water usually help clear pollutants away. On some days, pollution drifting in from farther away outweighs local sources. Levels are generally highest right next to busy roads and drop off quickly with distance.
In the mildest months, December to February, calmer nights at around 10°C allow traffic pollution to build up near the ground. By contrast, with summer temperatures averaging only about 18°C, ozone rarely becomes a serious problem. Wildfire season runs roughly from June to September, when smoke from fires, near or far, can bring hazy days and very poor air quality.

When is air pollution at its worst in Santa Venetia?
In the mildest months, December to February, calmer nights at around 10°C allow traffic pollution to build up near the ground. By contrast, with summer temperatures averaging only about 18°C, ozone rarely becomes a serious problem. Wildfire season runs roughly from June to September, when smoke from fires, near or far, can bring hazy days and very poor air quality.
Are air quality levels in Santa Venetia 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. |
