Air Quality Data
The District operates four air monitoring stations within its tri-county jurisdiction of Humboldt, Del Norte and Trinity counties:
Del Norte County:
  • Crescent City Station
Humboldt County:
  • Jacobs Station
  • Humboldt Hill Station
Trinity County:
  • Weaverville Station
The District regularly provides a status and overview of current air monitoring activities to its Governing Board in the most recent Ambient Air Quality Monitoring Status Report.

Data collected at these stations is reported to the EPA for determining compliance with the Federal Ambient Air Quality Standards. The District's historical air monitoring data is most easily accessed through the California Air Resources Board (CARB) databases: iADAM or AQMIS.
EPA Radiation Monitoring
Data from a local radiation monitor owned by EPA but maintained by the District can be found via the EPA Radnet website.
