AbstractTotal snow depth is determined by measuring the time of flight of an ultrasonic wave packet emitted from a sonic transmitter above the snow surface and reflected from the snow surface back to the receiver/transmitter system. The light-weight system is battery powered (operating time without battery change at least 8 months) and can be fixed to any post above the snow surface. The absolute precision is better than ±0.03 m. Data and commands are transmitted by a single two-wire system up to several kilometres.
