Air quality in Los Alamos is driven mostly by high mountain air — generally excellent, though nearby wildfires can bring smoke. Overall, Los Alamos sees air quality that tracks fairly closely with typical conditions for its wider region. Visitors and residents alike tend to notice the clearest air outside the warmest summer weeks.

When is air pollution at its worst in Los Alamos?
Los Alamos's air quality follows a clear seasonal pattern: winter is generally the cleanest season, with cooler temperatures and less dust in the air, but intense summer heat combines with occasional dust events to create the year's worst episodes. Sudden haboob-style dust storms can appear with little warning during the spring wind season.
Are air quality levels in Los Alamos 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.
