Abstract Through the US EPA STAR Grant: “Engage, Educate and Empower California Communities on the Use and Applications of Low-cost Air Monitoring Sensors”, led by AQ-SPEC at the South Coast Air Quality Management District, approximately 400 low-cost sensor devices (for both PM and PM combined with O3 and NO2) have been deployed across 14 California communities. The current phase of the project has involved meeting with participants to discuss their experience installing and using the sensors as well as results from a preliminary analysis of the data, which was conducted by our team. Here we will share an overview of the network’s performance and reliability as a whole. In terms of individual sensor performance, the participation of 14 different communities offers the opportunity to examine performance with respect to reference instrumentation across different field sites, in different environments. We will also share several examples of the data analysis, which was conducted with the aim of providing insight into communities’ questions regarding sources of interest. This initial analysis has already led to valuable insights regarding the usefulness and limitations of data from low-cost particulate matter sensors, insights that we anticipate will be valuable to other individuals and communities interested in leveraging sensors to learn more about their local air quality.
