Abstract: At 24 times the physical size of Switzerland, British Columbia contains a wide variety of Avalanche prone terrain in a number of different and often unpredictable climatic zones. For about 20 years, avalanche forecasters have used automatic weather stations in BC for synoptic observations of the weather and snowpack, often from very far away. Successful use of the technology has led the way for expanding their use into the field of road temperature and condition forecasting. In light of these factors the current suite of supported sensors is reviewed including some specific details on sensor operations. Some factors in geographic station siting are mentioned with examples. Sensor and derived data output formats are disclosed with subjective notes on sensor reliability. Some techniques and principles fundamental to reliable operations in winter are presented.
