Get to know our project by watching our webinar from December 2018! The overall goal of the project is to collect spatially dense, quality PM2.5 data (fine atmospheric particulate matter which can be a health hazard to some when levels are high) using low-cost sensors deployed by citizen scientists. By employing citizen scientists and low-cost sensors, our goals are to: • Test and demonstrate the feasibility of a sustainable cost-effective air quality sensor network that can be successfully deployed. • Motivate citizen scientists to continue these measurements, take ownership of the Air Quality (AQ) around them, increase public awareness and take personal measures to minimize pollution and lower harmful exposure. • Improve the value of satellite datasets from NASA missions through improved scientific understanding, and more importantly, generate widespread usage of NASA data and tools by motivated citizens, effectively creating a new generation of scientists.
