TODAY'S AIR QUALITY

What is the air quality right now?

​There are a couple ways to easily find out:  ​

We really like Fire.AirNow.Gov - this USFS-EPA site shows fires, smoke, and PM2.5 (fine particulate matter; the main pollutant of concern) from both permanent and temporary monitoring locations around the U.S.  You can set the site for your location and be sure to toggle on the smoke plumes. Click on the map, below.

Looking for a Smoke FORECAST? We like this new app which uses data from NOAA to forecast ahead 24 hours. (Sorry - it's only available for iPhones right now.) Search Air Quality Index in the Apple  store.

What is AQI?

The gauge above shows the current air quality index for Missoula MT within the hour. The Air Quality Index highlights different categories of air quality ranging from good to hazardous. The higher the AQI, the unhealthier the air quality is and the more it can affect your health. Different color categories correspond to a different range of air quality with green being the best and maroon representing hazardous air quality.

no monitor?

If don't live close to air quality monitors, these visibility guidelines may help you gauge local smoke levels. Click HERE to see what the different categories mean and how they affect us.

Visibility Guidelines

Cannot see 5 miles? Unhealthy Air
Cannot see 2 miles? Very Unhealthy Air
Cannot see 1 mile? Hazardous Air

How to estimate air quality based on visibility:
  • Use pre-determined landmarks that were established on a clear day for distances.
  • Face away from the sun.
  • Determine the limit of your visible range by looking for targets at known distances (miles).
