What WLS Institute for Snow and Avalanche Research does
SLF is a Swiss federal research institute, part of WSL within the ETH Domain, that conducts research and provides public services focused on snow, avalanches, permafrost, alpine natural hazards, and mountain ecosystems. Its flagship public safety product is the daily avalanche bulletin for the Swiss Alps, delivered through the whiterisk.ch platform and the White Risk mobile app, with e-learning and tour planning functionality now in its 20th year. Beyond the bulletin, SLF operates the proprietary SNOWPACK snow cover model for avalanche warning and snow hydrology, the RAMMS simulation software for avalanches, debris flows, and rockfalls, and the EnviDat open environmental data portal.
The institute has developed a suite of proprietary scientific instruments (SnowMicroPen, SnowImager, InfraSnow, SLF Snow Sensor) and operates unique large-scale field infrastructure including the Weissfluhjoch test site with 80+ years of continuous measurements, the Vallée de la Sionne avalanche dynamics facility, and the Illgraben debris flow observatory. Headquartered in Davos Dorf with additional sites in Birmensdorf, Sion, Lausanne (EPFL), and Cadenazzo, SLF employs approximately 180 researchers and technical staff from multiple nations and collaborates with ETH Zurich, MeteoSchweiz, the World Meteorological Organization, the Alfred-Wegener Institute, and other international research partners. The CERC research centre, co-funded with the Canton of Grisons, extends the mandate into climate change, extreme events, and natural hazards in alpine regions.
SLF's business model is government-funded research rather than commercial revenue generation. Operations are financed through Swiss federal appropriations channeled via WSL and the ETH Domain, with supplementary co-funding from cantons (e.g., Grisons for CERC) and from international research collaboration. Direct commercial revenue is limited: public avalanche and weather data are provided free of charge, while small fee-based services (CHF 6 per person for guided tours, instrument sales) are operationally minor. Pricing for tours follows unit-based pricing (CHF 6 per person / minimum CHF 80 per group / CHF 70 school group / CHF 200 evening group). Customer segments are dominated by Swiss federal and cantonal authorities for hazard management, with mountain recreationists and the international research community as secondary user groups.
