    • Phoenix-as-a-Testbed for Air Quality Sensors (P-TAQS) Dataset used in exploring the Seasonal Effects in the Application of the MOMA Remote Calibration Tool to Outdoor PM2.5 Air Sensors

    Metadata Updated: April 17, 2025

    Maricopa County partnered with EPA Office of Research and Development to evaluate the utility of sensors to capture wood burning episodes. For this study, PM2.5 sensors were collocated at three air quality monitoring stations within this targeted geographic area. Namely, Durango Complex, West Phoenix, and South Phoenix (designated as DC, WP and SP) for a period of 2 years to better understand sensor performance, comparability with regulatory grade monitors, and to explore drift and changes in performance over time. Approximately 6 months later, phase II began a year+ field study using sensors in a distributed network with FRM/FEM monitors to measure PM2.5 to characterize the impact of local air pollution sources—targeting the wintertime heating season in which wood combustion is the principal air pollutant source of interest; other sensors to be deployed during Phase II include black carbon sensors.

    The Zenodo link provides raw PM2.5 data collected as part of the P-TAQS study from these PurpleAir sensors and reference instruments deployed at fixed sites at 1-minute time resolution ordered by site and date/time.

    This ScienceHub entry contains the processed data files used to create the Figures in the manuscript titled "Seasonal Effects in the Application of the MOMA Remote Calibration Tool to Outdoor PM2.5 Air Sensors"
