Palmer Air Quality Monitoring Data - PM2.5

The interactive charts below show historical data from this monitor. The Alaska Air Monitoring Plan contains more information about this monitor.

 

Note: The vertical axis of these charts extend from -5 µg/m3 to 50 µg/m3. Negative PM2.5 concentrations are included based on EPA reporting guidelines and are within the noise levels of the instrument when the ambient PM2.5 concentration is near zero.


The following graphs show the 24-hour averaged PM2.5 concentrations measured at the Palmer Air Quality Monitor from 2015 through 2000.
