How to use the new Fire and Smoke Map

The new Fire and Smoke Map on the Oregon Smoke Blog shows the latest information about smoke in the state, with some added features not available in previous versions.

The map still shows air quality ratings and the locations of fires burning around Oregon. Click on a colored shape to get more information about the air quality and related health recommendations for that location.

The new map also has nine layers with additional information that can be toggled on and off. To access the layers, press the layer icon in the upper right corner of the map. It looks like three squares stacked on each other:

Then click the check boxes on the left side of the layer box to toggle layers on or off.

Layer options include:

Air Quality Layers

The new map shows three types of air quality monitors and sensors:
  • Permanent Monitors are owned and maintained by governmental agencies at the local, state, tribal and federal level. Permanent monitors are turned on by default.
  • Temporary Monitors are owned and maintained by government agencies on a temporary basis, often deployed near large fires. Temporary monitors are turned on by default.
  • Low-Cost Sensors are owned and placed by individuals and organizations in the PurpleAir sensor network. These low-cost sensors may not be properly maintained or show accurate data and are for informational purposes only. They are not used for regulatory purposes because of variable data quality. Low-cost sensors are turned off by default but can easily be turned on.
Fire Information Layers
Smoke Plumes Layer
  • Smoke Plume Extent: Shows a gray overlay representing smoke plumes across the state and beyond. These plumes are based on an analysis of satellite data by the NOAA’s Hazard Mapping System.
Special Smoke Statements Layer
  • Boundaries: Shows a blue outline around areas that have Smoke Forecast Outlooks issued by the Interagency Wildland Fire Air Quality Response Program’s Air Resource Advisors.
Basemap Layer
  • Aerial: Shows a Google Earth style topographical map.
  • Terrain: Shows a Google Maps style geographical map.
The new Fire and Smoke Map was designed and is maintained by the U.S. Forest Service and Environmental Protection Agency.
