Air Quality Index

Air quality measurements presented on this page are part of a research project managed by the Desert Research Institute and the Nevada Division of Environmental Protection. The project aims to expand wildfire smoke monitoring and messaging into rural Nevada.
The sensors used for measuring air quality are still in the testing phase and their accuracy has not been fully verified. As such, the Air Quality Index reported here may not be reflective of actual conditions, or it may differ from what other sensors report.

For more information about air quality, please refer to AirNow at or AirNow reports air quality using the official U.S. Air Quality Index (AQI), a color-coded index designed to communicate whether air quality is healthy or unhealthy.

Similarly, the hourly measurements collected and displayed here are not intended to be directly compared to the National Ambient Air Quality Standards, and no conclusions on the attainment status of the covered areas should be inferred. For more information on Air Quality Standards and attainment, please visit

Daily AQI Color Levels of Concern Values of Index Description of Air Quality
Green Good 0 to 50 Air quality is satisfactory, and air pollution poses little or no risk.
Yellow Moderate 51 to 100 Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Orange Unhealthy for Sensitive Groups 101 to 150 Members of sensitive groups may experience health effects. The general public is less likely to be affected.
Red Unhealthy 151 to 200 Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.
Purple Very Unhealthy 201 to 300 Health alert: The risk of health effects is increased for everyone.
Maroon Hazardous 301 and higher Health warning of emergency conditions: everyone is more likely to be affected.
