EPA’s Village Green Sensor-Based Air Monitoring Stations: Long-term Performance of PM2.5 Sensors
Conner, T., Sue Kimbrough, R. Williams, B. Johns, J. White, AND G. Hagler. EPA’s Village Green Sensor-Based Air Monitoring Stations: Long-term Performance of PM2.5 Sensors. 2018 International Aerosol Conference, St Louis, MO, September 02 - 07, 2018.
Poster presented at the 10th International Aerosol Conference, Working Group: Low-Cost and Portable Sensors
The Village Green Project was established to demonstrate the capabilities of new real-time monitoring technology and to help communities learn about local air quality by locating EPA-developed sensor based air monitoring stations in publicly accessible locations. A pilot station in Durham, North Carolina demonstrated the system’s ability to monitor several common air pollutants in real-time and make the data available online. The Village Green Project has since expanded to seven additional locations across the U.S. to evaluate the station’s operation under different weather conditions and to increase awareness of this new community-based air quality monitoring system. The solar and wind powered station is a park bench structure with instruments that provide minute-to-minute air measurements for ozone, particle pollution and weather conditions. Though the overall goal of the project is to provide the public and communities with information previously not available about their local air quality and engage communities in air pollution awareness, the data acquired at these stations provide EPA researchers with the opportunity to evaluate long-term performance of sensor devices. Some stations have been reporting PM2.5 data approaching 2 years. In this presentation, we report on the long-term performance of the Village Green station PM2.5 sensors (MIE pDR-1500, Thermo Scientific) deployed in a variety of locations and conditions.
