Submit Smell Reports
Install the app onto your mobile devices. At the first launch, the app will take you to the "Settings" tab. You can choose to enter personal information, which will go to the Allegheny County Health Department (ACHD) with every smell report you submit, so that they can follow up with you if needed. The "Settings" tab also lets you choose the type(s) of app notifications.
When you experience a pollution odor outdoors, launch the app and pick a rating for the smell. Adding a description of the smell (e.g. industrial) is highly encouraged, since this can help the county isolate the source. You also have the option to (but are not required to) list symptoms attributable to the experience and send a personal note/question to ACHD. Please only enter information that you are comfortable with sharing anonymously on the public Smell PGH map.
Visualize Smell Reports
At the same time your smell report is added to the public Smell PGH interactive map visualization. A triangle icon shows the color of your smell rating that represents your report. Your location is obscured on the map by slightly shifting the coordinates to protect your privacy. Tapping a smell report icon on the map will show the details of the report, including the: date, time, rating, description (if provided), and symptoms (if provided). No personally identifiable information is shown on the map.
In addition, circles on the map indicate federal air quality monitoring stations, where the color denotes the level of fine particulates. Blue arrows that appear near each circle denote the wind direction as reported from that monitoring station. You can explore this map further by panning and zooming. You can also tap on the playback button to animate the smell reports, sensor readings of fine particulates, and wind information over time.
