The UAS pollution pilot started in June 2021 and asks respondents to continuously wear an Atmotube air quality monitor when they go out, although they may remove it at home. The Bluetooth-enabled device communicates with a smartphone app and collects pollution data (PM1.0, PM2.5, PM10.0, and VOC) as well as weather data (temperature, pressure, and humidity) at 1-minute intervals, with the app uploading the data directly to a server. The battery lasts at least a week, making continuous monitoring feasible. The main contribution of the study is measuring air quality exposure at the individual level and providing a fine-grained, high-temporal-resolution picture of personal pollution sources throughout the day, including exposure at home, at work, during commuting or travel, and in other environments. The long-term goal is to better understand how air quality affects health, cognition, and wellbeing across different populations and living environments nationwide.
