Cold subarctic air is what shapes air quality most in Nome, and clean arctic air with excellent visibility most of the year. That mix of factors is fairly representative of towns in this part of the country. None of this replaces checking the current forecast before heading outdoors in Nome.

When is air pollution at its worst in Nome?
Nome's air quality follows a clear seasonal pattern — the short window of late spring typically offers the year's cleanest air, whereas long stretches of summer wildfire smoke can dominate the interior for weeks at a time. Coastal communities generally see milder swings than the more extreme interior valleys.
Are air quality levels in Nome 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.
