Read about EPA’s research to improve the accuracy of sensors. EPA and USFS may update the sensor map layer several times during the pilot project, as we respond to feedback and work to improve the map. The circles represent the permanent, stationary long-term monitoring stations that are used to report outdoor air quality to the public on AirNow.gov. If an icon is gray, that indicates that data is not available (this could occur for several reasons). PM2.5 specifically refers to fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Users can use both websites to learn more about air quality in their area. At the time of the release of the Pilot, only one state has chosen to remove their PurpleAir data from the program. Data from all of these sources is shown in the color-coded Air Quality Index (AQI). Sensor Data Pilot: EPA and USFS are conducting a pilot project to add data from low-cost sensors to the Fire and Smoke map. When you visit the Fire and Smoke Map on AirNow.gov, you will be able to select “low-cost sensors” from the map layers to see particle pollution (PM2.5) information from sensors, along with information from AirNow monitors and temporary monitors deployed during fires. Additionally it will not represent smaller smoke plumes or smoke plumes otherwise not detected by the satellite images (e.g. Data for temporary monitors is obtained through the AirSis and the Western Regional Climate Center (WRCC) data feeds. There is a “learn more” link on each of these for access to more information. For most low-cost air sensors, little is known about the locations, including how close sensors are to any sources of pollution. While these sensors don’t meet the rigorous standards required for regulatory monitors, they can help you get a picture of air quality nearest you especially when wildfire smoke is in your area. This pilot project provides the opportunity to see the performance of the correction in various situations and geographic locations, EPA may revise the corrections and/or apply additional quality control criteria as more information becomes available during the pilot project. PurpleAir data is collected every 2 min, but only displayed after aggregating to a calendar hour (e.g. This means that the sensor data can use the AQI color scale when it appears alongside the monitoring data that is already on the AirNow Fire and Smoke map. Sensor failure is often indicated by the sensor not reporting, or a large disagreement between the two channels on the PurpleAir devices. Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. EPA and USFS are working to make changes that will update the map more frequently as the pilot project progresses. Special Smoke Statements: Smoke Outlooks issued by the Interagency Wildland Fire Air Quality Response Program’s Air Resource Advisors that apply to the location of interest will appear here. Click on the AQI and concentration tabs to see a time series of AQI values (NowCast) or PM2.5 hourly concentrations for that monitor. Data for permanent monitors is obtained through the EPA AirNow system which aggregates data feeds from a large number of agencies and organizations on an hourly basis. Central Point is on a level 2 alert. To refresh the data with the latest information press the button in the lower left corner or click on the prompt. This will reduce the potential impact of missing RH data to a maximum of 4 μg/m3. Not signed up? The map will undergo several phases of improvements over time, with the goal of having an upgraded version available in time for the 2021 fire season. That’s possible because of the steps EPA and USFS take to mitigate bias in sensor data, apply quality assurance measures and apply the NowCast algorithm to show the data in the context of the Air Quality Index. Portland Fire Incidents: Last 12 Hours This map contains the most recent, closed, non-confidential, 911 calls for service received by Portland Oregon’s 911 system. Daily Situation Report - Daily statistics of fire activity reported by agency and local dispatch offices in the region. To effectively utilize the mass amounts of sensor data, EPA developed an equation to correct the sensor data to bring it more in line with data from official monitoring stations. due to cloud cover, or because they have occurred after the satellite image was taken). The AQI shown on the Fire and Smoke Map is specifically focused on fine particulate matter, also known as PM2.5. Most sensors report out every few minutes. Project Lead: Sim Larkin, USFS Sensor data is not used on other maps on the AirNow website and is not used to generate the current air quality or forecast AQI shown on the “dial” on the AirNow home page or AirNow app. Fire and smoke plume detections are from the NOAA’s Hazard Mapping System Fire and Smoke Products.
