Special Air Monitoring Projects

Learn about special purpose air quality monitoring projects in the Bay Area and monitoring at refineries.

Local Air Monitoring Projects

On occasion, the Air District installs and operates temporary air quality monitoring stations and/or equipment in the Bay Area as resources allow. These monitoring stations are usually placed to:

  • Determine downwind effects from one or more pollution sources.
  • Find out whether air quality measurements at the closest permanent monitoring station are accurately representing pollutant levels in an area of interest.
  • Collect more information about specific pollutants.

View information about recent monitoring projects below.

  • Cupertino Monitoring Project (Sept. 1, 2010 – Dec. 31, 2013)
  • Forest Knolls Monitoring Project (Jan. 2013 – present)

Monitoring at Refineries

Monitoring Expert Panel

In order to implement monitoring at Bay Area refineries the Air District assembled an Air Quality Monitoring Expert Panel to recommend technologies, methods, and tools to improve monitoring capabilities near these facilities.

Community Air Monitoring Near Refineries

The Air District is implementing a program to enhance long-term air monitoring in the community near each refinery which will provide additional information about the cumulative levels of pollution experienced by people in these areas. 

In the first of this series, the Air District and the City of Benicia have identified candidate locations in Benicia for a new air monitoring station. At a virtual workshop on June 30, community members and stakeholders will discuss and review the site selection process and provide feedback on a community air monitoring station within the Benicia community.

PM2.5 Design Values With and Without Wildfire Smoke Episodes

This preliminary analysis provides a rough evaluation of how air quality trends would be different without the impact of a few of the largest most recent wildfires, by removing days in 2017 and 2018 impacted by wildfire smoke from the calculation of PM2.5 design values.

As shown in this document, when days impacted by wildfire are excluded, the 2017-2019 PM2.5 design values are below the applicable state and federal standards.
