What is the air quality today?
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 and the main pollutant of concern in wildfire smoke) from both permanent monitoring and temporary monitoring locations around the U.S. You can easily turn on (or off layers) and set it for your location. Click on the upper map, right. Today's Air is the Montana site that provides information on hourly levels of PM2.5 across the state. From the MT Dept. of Environmental Quality, this site is also helpful for understanding smoke exposure for Montana communities. Click on the lower map, right. |

![]() 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 and is based on 24 hour averages). |
