Analysis of potential avalanches detected by Sentinel-1 SAR over Norway

The European satellites Sentinel-1 A and B have been in operation since 2014 and 2016, respectively. The radar onboard them allows the detection of avalanche debris.

A consortium around the Norwegian Avalanche Warning Service operates a continuous monitor of avalanche activity over large parts of Norway using this technology (satskred.nve.no).

The study will analyze automatic avalanche detection from the last three to four winter seasons. The study should describe variations in the amount, timing, and positioning of avalanches. Variations in avalanche activity could be caused by varying snow conditions, constraints in detectability, or other circumstances.

The goal of this study is to explain potential variations in avalanche activity, identify sources of false alarms and suggest concepts to prevent false alarms.
