Local Environmental Conditions
Around this location in New York, traffic is light and there are few concentrated sources of air pollution. Its position by the Long Island Sound brings breezes that often clear pollutants away. Trees nearby help filter some particles from the air, though in hot weather they also emit compounds that feed ozone formation. On some days, pollution drifting in from farther away outweighs local sources.
Cold spells from November to March, at around -1°C on average, are when smoke from wood burning and traffic lingers longest. By contrast, hot afternoons from June to August, averaging 25°C in the warmest month, are when ozone is most likely to build up. On the plus side, stronger winds around March, about 15 km/h on average, usually bring some of the cleanest air of the year.

By contrast, hot afternoons from June to August, averaging 25°C in the warmest month, are when ozone is most likely to build up. On the plus side, stronger winds around March, about 15 km/h on average, usually bring some of the cleanest air of the year.
Are air quality levels in Bronx & Pelham Bay Park 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. |
