The TEMPO sensor, launched by NASA, monitors air pollution across North America in real-time. Positioned in a geostationary orbit, it captures high-resolution data on pollutants like nitrogen dioxide and ozone hourly, enabling neighborhood-level insights. This data will support public health research, pollution monitoring, and policy formation, marking a significant advance in earth science. TEMPO is part of NASA’s Earth Venture initiative, designed for accessible and affordable environmental monitoring.
