255 polygons of wet snow avalanches exceeding 0.0125 km^2 in the Davos area, documented by the Swiss avalanche warning service from October 2011 to September 2014. The dataset contains georeferenced outlines of both release and deposit areas, with metadata including the date of occurrence. This dataset was provided by ENVIDAT and is the underlying data for a submitted journal article.
Use Cases
- Modeling avalanche hazard risk based on georeferenced avalanche outlines.
- Analyzing seasonal patterns of wet snow avalanche activity based on date metadata.
- Studying the spatial distribution of large avalanches based on the 0.0125 km^2 size threshold.
- Evaluating coupled snow cover and avalanche dynamics simulations as referenced in the description.
Strengths
- 255 documented avalanche events exceeding a specific size threshold of 0.0125 km^2.
- Georeferenced outlines contain both release and deposit areas.
- Includes date metadata for temporal analysis over a defined period from 2011 to 2014.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2018-01-01 00:00:00; freshness should be verified.
- Data may reflect geographic bias inherent to the specific Davos area.
