The relationship between various atmospheric parameters and air pollutants is essential for schools that value outdoor activities to understand fully. This research used GLOBE protocols to measure weather parameters such as air temperature, humidity, pressure, and dew point. Researchers compared their GLOBE data with ground-level ozone, particulate matter (PM2.5), and Volatile Organic Compounds (VOCs) measured using consumer-grade instruments known as PurpleAir, PocketLab Air, and ATMO Tube. Data collected from each device was compared with data reported by local professional-grade devices when available. This data allowed researchers to assess the accuracy of each device. This research aimed to analyze some of the atmospheric factors contributing to high PM2.5 levels. All measurements were taken at or near solar noon to maintain reporting consistency. The data collected and analyzed in this research showed that high PM2.5 levels do appear to correlate with high ozone levels and high air temperatures. Researchers found that the PocketLab Air and ATMO Tube had measurements typically below locally reported data, but they constantly varied with professional devices. Reducing the intense, long-term effects of ground-level ozone, particulate matter (PM2.5), and Volatile Organic Compounds (VOCs) is crucial for student health and safety during recess and when practicing and performing athletic outdoor-based sporting activities. This longitudinal research extended a project conducted previously to include data taken during two different seasons and years. Air quality data collected at schools is vital as atmospheric conditions can vary considerably on a microscale level.
