In Las Vegas, dry northeastern New Mexico high-desert air is the main influence on air quality, and air quality is generally very good outside of windy dust events. None of these influences are extreme on their own, but together they shape the local pattern in Las Vegas. Wind direction on any given day can shift things noticeably from the seasonal norm.

When is air pollution at its worst in Las Vegas, New Mexico?
Air quality in Las Vegas shifts across the year: winter is generally the cleanest season, with cooler temperatures and less dust in the air, but spring winds can kick up sudden dust storms that spike particulate levels sharply for a day or two. Sudden haboob-style dust storms can appear with little warning during the spring wind season.
Are air quality levels in Las Vegas, New Mexico 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.
