I n the same way ocean buoys have revolutionized maritime weather forecasting, drone-based sensor networks are poised to do the same for the skies above us. Inspired by the work of Sofar Ocean, whose global Spotter buoy network delivers real-time insights into ocean conditions, a new vision is taking shape—this time, overhead. It's called DroneNet: a scalable, modular, and mobile network of airborne drones designed to sense, analyze, and report atmospheric data in real time.
