Local Environmental Conditions
With buildings covering much of the area around the center of Gadsden, traffic and other urban emissions are the biggest local influence on air quality. In cold weather, wood burning and other home heating become a noticeable source of fine particles. Pockets of trees and green space help filter a small share of the particles from traffic.
From May to September, strong sunshine and temperatures around 27°C drive ozone formation, with levels peaking in the afternoon. Fine particle levels climb in January, as home heating and traffic combine with cold, still air averaging 5°C. Spring dust storms from the Asian deserts can affect the area mainly from March to May.

When is air pollution at its worst in Gadsden?
From May to September, strong sunshine and temperatures around 27°C drive ozone formation, with levels peaking in the afternoon. Fine particle levels climb in January, as home heating and traffic combine with cold, still air averaging 5°C. Spring dust storms from the Asian deserts can affect the area mainly from March to May.
Are air quality levels in Gadsden 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. |
