Southeast Alaska Air Quality Sensor Data

DEC is in the process of testing and deploying several AQMesh sensor pods to locations in Southeast Alaska to assess ambient concentrations of a variety of particulate and gaseous pollutants. The map will be updated as more units are deployed. Data from the pods are not available until approximately 15-20 minutes after the top of the hour. 

Current Data Maps (SO2, ppb)

The map displays the latest 1-hour average SO2 concentration recorded at each location.  Data for each hour are not available until 15-20 minutes past the top of the hour.  During this lag period, the map displays the data from the second most recent hour.  Click on any site to view a table containing 1-hour average concentrations of all parameters during the previous three hours.

Data from all reporting sensor units are shown as 15-minute average values for the preceding 24 hour period.  You can click buttons to view different parameters.


Study Information

DEC is using AQMesh sensor pods that monitor particulate matter (PM), CO, NO, NO2, SO2, wind speed and direction, temperature, relative humidity, and ambient pressure. The pods mount to a pole, can be powered using solar panels or AC power, and transmit data using a cellular modem.
