The Fire and Smoke Map also shows smoke plumes, fire locations and special smoke statements. That’s possible because of the steps EPA and USFS take to correct sensor data, apply quality assurance measures, and apply the NowCast algorithm to show the data in the context of the AQI. AirNow’s Fire and Smoke Map allows you to compare current air quality from low-cost sensors, the regulatory grade monitors that report to AirNow, and temporary monitors that USFS, states, tribes and local agencies deploy on fires – and to see all of that information in one place. You can use them all – but it’s important to understand what different sites show. Which site should I use during a fire – the AirNow Fire and Smoke Map, my state’s air quality site, or a private air sensor site? See the end of this document for instructions. If you have this experience, let us know. If the dial for your area doesn’t match what you are experiencing during a fire, it may be because no fine particle monitor is assigned to your reporting area instead, your reporting area may be tied to a monitor for ozone or coarse particle pollution. When there are multiple monitors in a reporting area, the monitor reporting the highest amount of pollution is used to generate the dial shortly after the top of the hour. Reporting area boundaries are determined by the state, local and tribal air agencies that provide data to AirNow. That information is tied to a geographic “reporting area” and the particle pollution or ozone monitor(s) it contains.
#PURPLE AIR MAP CODE#
AirNow generates a local dial based on the zip code or city name you enter when you first visit the page. The air quality data used to generate the dial readings comes exclusively from high-quality, regulatory grade monitors. At this time, sensor data are used only in the Fire and Smoke Map pilot project and are not used elsewhere on AirNow, including for reporting the overall AQI for the day. The “dial” is the at-a-glance feature on the AirNow home page and AirNow app that shows you your current NowCast AQI, the primary pollutant (that’s the pollutant with the highest AQI out of all the monitors in the area as of the last hour update), and your air quality forecast for the day. In addition, a lack of information about the maintenance, or operation of these sensors, adds additional uncertainty to the data they produce. Because anyone can purchase and operate a low-cost sensor, EPA has little information about the location-related information that can influence their readings, such as how close sensors are to any sources of pollution. Air sensors are lower in cost, more portable, and generally easier to operate than the regulatory monitors widely used in the United States.
#PURPLE AIR MAP SOFTWARE#
This term often describes an integrated set of hardware and software that uses one or more “sensing elements” (also sometimes called sensors) to detect or measure concentrations of an air pollutant. These stations, considered the gold standard for measuring pollution in the outdoor air, are located according to EPA guidelines, remain in one place for many years, are maintained and operated by trained experts, and follow EPA quality assurance protocols.Īir sensors, also known as low-cost sensors, are a class of non-regulatory technology for measuring air pollution. What is the difference between a monitor and a sensor?ĮPA uses the term “air quality monitor” for regulatory air monitoring stations. And if you want to look at a map, check out the AirNow interactive map on the website by clicking on the map section just below the dial, clicking the “Monitors Near Me” link below the city name to the right of the dial, or by selecting it from “Maps & Data” at the top of the page.

When there is no wildfire in your area, using the “ dial ” on the main page at or the AirNow app also are good ways to get your current air quality information and forecasts. Forest Service, along with information on large fire incidents, satellite-detected fires, smoke plumes and special smoke statements. In addition to sensor data, the map features fine particle pollution (also known as fine particulate matter, or PM 2.5) data from the regulatory grade air pollution monitors that report to AirNow and from temporary monitors deployed by the U.S.

The goal of the pilot, launched in August 2020, is to provide additional information on air quality during wildfires, especially in areas where AirNow monitors or Forest Service temporary monitors may not exist. Environmental Protection Agency (EPA) and the U.S. That’s because we’ve been able to add data from low-cost air sensors to the map as part of a pilot project between the U.S. During a wildfire, we recommend using the AirNow Fire and Smoke Map.
