![]() I use PurpleAir data often and it’s useful, as an indicator of worsening or lessening PM2.5 levels, but it cannot be confused with standard reference methods and 24-hr average AQI health messages. Note, there has been a lot of conversation around PurpleAir using “US EPA AQI” when it’s not 24-hr average data from standard reference methods. Can PurpleAir data be used to provide near real-time air quality index (AQI) comparable to the regulatory network especially during smoke impacts What. Useful to community scientists or air quality professionals alike, PurpleAir sensors are easy to install, requiring only a power outlet and WiFi. It is 4-6 characters long and is used in making API calls to download data. Real time measurement of air quality on a public map. The sensor index is an identifying number unique to each sensor. That way you are presenting actual data and not an application of the AQI for purposes it was not intended for. This article will explain how to find a device’s sensor index. Only the first few miles (in purple) were ever constructed - the green line reflects. The PurpleAir Map is a real-time, free air quality map that you can use to view the air quality of specific areas worldwide. Lastly, read and summarize this document on interpretation and communication of low-cost sensors for measurements ( ) and explore the EPA’s Sensor Toolbox ( ).įor future articles, use the drop down on the PurpleAir map (where it says US EPA AQI) and change it to PM2.5 ug/m3. Connects: Valdez to Fairbanks, AK Route: Alaska 4 Length: 366 miles Road. Pollen and Air Quality forecast for Fairbanks, AK with air quality index, pollutants, pollen count and pollution map from Weather Underground. Third, remove the “Very Unhealthy” wording, as at the time of this screen shot the actual EPA AQI was NOT Very Unhealthy. This data is incomparable to standard PM2.5 reference methods which are subject to strict protocols to insure quality data. Second, note this is instantaneous data from low-cost sensors which are not calibrated, quality controlled, do not have standardized citing criteria, and have a lifetime of only 1-3 yrs. Our wireless coverage map is available online. Because at PurpleAir, we believe in making air quality knowledge accessible to everyone. First, remove the AQI legend (as the health messages are only intended for 24-hr average data from reference methods). View the UScellular cell phone coverage map to see the strength of signal where you use your phone the most.
