Human-triggered avalanches

This CSV contains the density of human-triggered avalanches relative to the total potential release area for each day and region with the same forecast sub-level. The following variables are contained: - *date* - date - *dangerLevel* - the danger level forecast valid on the day of interest - *levelBullSub* - the sub-level forecast valid on the day of interest - *rhoSz2* - density of avalanche larger or equal than size 2 per *pra* - *rhoSz3* - density of avalanche larger or equal than size 3 per *pra* - *pra* - total surface area in km^2, which is considered as a potential release area within the warning regions forecast with the same sub-level on the day of interest - *nRegions* - number of warning regions with the same sub-level

Observed danger signs

This CSV contains observational data on danger signs. The following variables are contained: - *date* - date of the observation - *sectorId* - this is the sector id as used in the Swiss avalanche forecast - *whumpfCracksFrequency* - observations with three classes NONE, RARELY, OFTEN - *dangerLevel* - danger level as forecast in the avalanche forecast the evening before - *levelBullSub* - sub level as forecast in the avalanche forecast the evening before

Rutschblock test results

This CSV contains the Rutschblock results used in the study. The following variables are provided: - *date* - the date the Rutschblock was observed - *sectorId* - the warning region identifier - *rbStab* - the stability class, as described in Figure 3 - *dangerLevel* - the danger level as forecast for the respective warning region on the day of the observation - *levelBullSub* - the danger level as forecast for the respective warning region on the day of the observation
