In Alliance, dry high-plains wind is the main influence on air quality, and this is generally very clean air, aside from wind-driven dust. Most days bring generally favorable conditions here, with occasional exceptions tied to shifting weather patterns. Longer-term residents of Alliance tend to plan outdoor activity around these predictable shifts.

When is air pollution at its worst in Alliance?
Alliance experiences a distinct seasonal swing in air quality — the calmest air usually arrives in winter, between planting and harvest dust events, whereas the combination of windy spring dust and hot, still summer days makes for the toughest stretch of the year. Wide-open terrain generally helps disperse pollution quickly once the wind picks up.
Are air quality levels in Alliance 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.
