Local Air Quality

This dataset contains air quality data collected using a PurpleAir Dual Laser Air Quality Sensor located at the Chapel Hill Public Library. The sensor measures fine airborne particulate matter with a diameter of 2.5 microns (PM 2.5) or less. PLEASE NOTE: We are currently experiencing technical issues with our air quality monitoring sensor. Repair efforts are under way, but reported values may not be accurate until full function is restored.

In addition to PM 2.5 measurements, this dataset includes readings for pressure, temperature and humidity. Because the PurpleAir sensor is designed primarily for measuring airborne particulate matter and not for ideal temperature sensing, temperature values are provided as is and are just for interest.
