Importance of Data: An End User's Perspective; What End Users Want

Part 1 of this two-part presentation provides information on why our monitoring data is so important and how it is used. Objectives for air monitoring data and examples of how the data is used by various end users will be covered.

With the recent increase in extended wildfire smoke events, it is more important than ever that our data gets out to the public. In Part 2 of this presentation, Tehama County APCD covers the topic of “what users want”. Tools used to determine the types of data users are looking for, different methods of delivering data to the public, and the development of outreach materials are reviewed. Tehama County APCD also covers examples of what they have done based on their experience with wildfires that have burned throughout the region.

Network Design; A Transition from Filter-based FRM to Continuous FEM

Part 1 of this two-part presentation provides an overview of federal regulatory requirements and considerations for designing an ambient air quality monitoring network. Topics include annual network plans, system modifications, and emerging challenges and innovations. 

In Part 2 of this presentation, the primary operator for the Redding monitoring site of the Shasta County AQMD describes the process of transitioning from a filter-based FRM (a R&P Partisol 2000) to a continuous FEM (a BAM 1022) as the primary PM2.5 monitor for regulatory purposes. The presentation includes reasons for the change, installation and collocation, maintenance and data validation, how it helped with COVID-19 impacts, and lessons that may help other districts looking to make the same change.

The Role of Meteorology in Regulatory Air Quality Modeling

This presentation gives an overview of the role meteorology plays in CARB's regulatory air quality modeling efforts. These efforts are carried out to keep California's air clean by keeping the concentration of air pollutants at or below the National Ambient Air Quality Standards (NAAQS) as part of the Clean Air Act (CAA).
