Instrumentation for Snow, Weather and Avalanche Observations

There have been an increasing number of requests in recent years for information on instrument specifications for snow and avalanche observations in new ski areas. The recent adoption by the Forest Service of uniform standards and requirements for snow, avalanche, and weather records in Class A winter sports areas on National Forest land has accelerated the demand for this information. This manual has been prepared specifically to answer the questions of what kind of instruments have been found satisfactory, how much they cost, where they can be ordered, and how they should be installed. 81 p.
