TODAY'S AIR
Today's Air is a Montana specific site that provides information on hourly levels of fine particulate matter (also known as PM2.5, the main pollutant of concern in wildfire smoke) across the state. This is your best site for finding accurate updates on PM2.5 and smoke exposure for Montana communities.

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).

If don't live close to air quality monitors (see the Today's Air map), these visibility guidelines may help you gauge local smoke levels. Click here to see what the different categories (unhealthy, very unhealthy, hazardous, etc.) mean and how they affect us.

This map shows fire locations and smoke plumes across the US. Zoom in or out and you can easily turn on our off  layers (like the green dots!) 
AIRPACT MAP
This map shows fine particulate matter patterns through western Montana and provides a great visual forecast of where the smoke is headed (up to 48 hours). Thanks Washington State University!
AIR NOW - Air Quality and Forecasts
Air now provides current and forecasted air quality information for Montana and other states across the U.S. Data is collected by the U.S Environmental Protection Agency. Hourly data on this site is not as accurate as the Today's Air site because of data averaging.

Smoke Sense App
Download the free Smoke Sense App for Android and iPhones

You can use the smoke sense app to learn about wildland fires and smoke health risks in their area, as well as report health symptoms and earn weekly badges.

​This app uses the same system as Air Now (it calculates AQI, not particulates specifically, and is based on 24 hour averages).
Visit the EPA's Smoke Ready Toolbox site for additional resources.
