Palmer PM2.5 Data

Palmer Air Quality Monitoring Data - PM2.5

The interactive charts below show historical data from this monitor. The monitor operated between January 1, 2010 and July 24, 2019 and was shut down due to budget cuts.  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 2019 through 2000.
