”How do laser technologies improve avalanche forecasting and avalanche detection
Dipl. Ing. Dr. Alexander Prokop, Univ. Doz.Universität Wien, Universität Graz, Snow Scan GmbH
Question of the day: How close are we to automatically measure snow pack properties spatially (in 4 dimensions)?
In the last 2 decades laser technologies improved the possibilities to measure snow pack properties in 4 dimensions significantly. Laser scanning provides snow depth measurements spatially in high resolution and high accuracy. Low cost automotive lasers increase applications for avalanche forecasting as avalanche release areas can be surveyed in high frequency. Moreover snow reflectance measured by the intensity of the back-scattered laser signal provides information of crystal size, form and wetness of the snow surface. Buried weak layers can be identified automatically, as snow surface properties can be measured right before snowfall. When a laser beam is send continuously trough a fiber optic cable seismic and acoustic signals can be measured every meter along the cable. This allows detecting avalanches in high spatial accuracy under all weather conditions. All those investigation techniques are currently deployed at the Lech Bergbahnen AG in the framework of the RSnowAut research project and are described and analyzed in this talk in detail.
