Manual and automatic detection of dry snow avalanches in Sentinel-1 SAR images

In recent years, the use of satellite-borne synthetic aperture radar for snow avalanche detection has increased. The ability of SAR to continuously monitor large regions has led to operational use of Sentinel-1 borne avalanche detection, or rapid mapping of extreme events [1]–[3]. It is thus critical to quantify the performance and accuracy of avalanche detection in SAR images. Thus far, validatio...
