What affects air quality in Las Vegas
Clark County explains that the Las Vegas Valley's shape and wind patterns place elevated concentrations of different pollutants in different areas, so monitoring sites measure different pollutants according to their valley location.
This is valley-scale siting context, not a current concentration, a forecast or a claim that the whole valley has uniform conditions.
Local monitoring and context
Clark County's Division of Air Quality describes a monitoring network with subnetworks for PM10, PM2.5, carbon monoxide, ozone and nitrogen dioxide in the Las Vegas Valley.
Pollutant coverage varies by station; the network does not supply this page's current data and no attainment status is asserted.
City air quality FAQ
How should I read the AQI for Las Vegas?
US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.
Is the air quality good for going outside?
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
Should I ventilate right now?
The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.
Why can air quality change during the day?
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.

Current data
This page uses US AQI.
Current and hourly air-quality values are CAMS-based model estimates, not measurements from a local monitoring station. They may not reflect street-level conditions.

The Where is the Air Monitored section links valley shape and winds to differing pollutant distributions. What Pollutants are Monitored identifies the PM10, PM2.5, CO, ozone and NO2 subnetworks.
Applicability: Official local or regional background only; not current conditions, citywide uniformity, regulatory attainment or this site's current-data provenance.
