Abstract: A sensor has been developed by the Snow Avalanche Section of the British Columbia Ministry of Transportation & Highways to accurately record temperature profiles through the snowpack at remote weather stations. The basic design is a four metre long fibreglass/epoxy tube with thermistors spaced every twenty centimeters. The thermistors are epoxied into a modified steel grease fitting and threaded into the tube. The fibreglass/epoxy tube has low thermal conductivity which will help prevent heat transfer between thermistors. In addition, the tube is filled with styrofoam beads to help prevent any heat transfer by creating a dead air space inside the tube. By observing the temperature profile it is also possible to observe the air temperature and a close approximation of the depth of snow on the ground.
