EPA AIRNow

Updates to EPA’s AirNow App increase public access to information about air quality all year, including during wildfires. The app updates add two maps to give the public additional, actionable information about air pollution at their location: the popular Fire and Smoke Map, which provides information on fire locations, smoke plumes and air quality from monitors and low-cost sensors; and the AirNow Interactive Map, which shows ozone and particulate matter from air quality monitors across the country. The AirNow Interactive Map uses data from air monitors operated by experts to reflect particulate and ozone pollution in a given area. While particulate matter (also called “particle pollution”) is the key pollutant in smoke, ozone also can be elevated during wildfires. While the Fire and Smoke Map is the map to use during wildfire season, the Interactive Map shows ozone and particle pollution at any time of year.

Various bug fixes and improvements, including: - Better handling for stale data values - Removed the ability to add a duplicate place - Fixed an issue with multiple primary forecast values - Properly handles values beyond the AQI index now - Fixed some text boundary issues on the detail screens

Version 2.0 is an update to the AirNow look and feel. It includes: - A dial for indicating AQI - Multi-day forecast - The ability to track and save air quality for multiple cities
