The AQI for particle air pollution is a 24-hour index that’s tied to nationwide requirements for particle pollution and the scientific research behind them. To show the newest hour of air high quality as the AQI, AirNow uses a formula known as a “NowCast” to estimate the AQI for the current hour. Real-time air high quality monitoring knowledge is preliminary and will only be used for informational functions, not for regulatory or attainment decisions. Data for low value sensors is at present obtained via the PurpleAir community with probably different networks added sooner or later. Think you understand your neighborhood higher than Google’s algorithm? If you wish to work together with Maps while you’re driving, you don’t need to actually take your eyes off the highway.

PurpleAir information is collected each 2 min, however only displayed after aggregating to a calendar hour (e.g. 2-3pm) and processing through the correction factor and NowCast AQI algorithm.

To see other pollutants, go to the AirNow interactive map, which shows ozone, PM2.5, and PM10 knowledge that official outside air high quality air monitoring stations report again to AirNow. Low-Cost Sensors Low-Cost Sensors are transportable, generally simpler to operate than regulatory-grade screens, and out there on the industrial market. Most low-cost sensors do not have information quality that’s corresponding to the monitoring stations operated by air businesses. For the pilot, sensor data have been averaged to an hour, QA screened, corrected for bias, and NowCast.
