    Wireless Sensor Networks To measure real-time data (ex: snowpack) over a large area, we need many sensors planted in representative locations and seamlessly sending back field measurements. A Wireless Sensor Network (WSN) makes the best solution. 10 WSNs are currently installed north of the Sierra-Nevada mountain chain. A 2D map of the sites can be found here. A 3D map is also available.
