Air quality in Prescott is driven mostly by high desert dryness — generally excellent, aside from occasional wildfire smoke. These factors combine to give Prescott a fairly typical seasonal air quality pattern for this part of the country. Local topography and prevailing winds both play a role in how quickly conditions change.

When is air pollution at its worst in Prescott?
Prescott's air quality follows a clear seasonal pattern, as the cooler winter months typically bring the cleanest air of the year; by contrast, summer heat drives ozone formation, and blowing dust from spring winds can push particulate levels up abruptly. Monsoon storms in July and August can either clear the air with rain or stir up dust ahead of the storm front.
Are air quality levels in Prescott 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.
