Selected wet snow avalanche activity data Davos, Switzerland (2011-2014)

Polygons of wet snow avalanches in the Davos area, as documented by the Swiss avalanche warning service. The georeferenced outlines of the avalanches contain both the release as well as the deposit area, but without separating between both. The dataset is a subset of the total record of 1615 avalanches classified as wet snow avalanches from October 2011 - September 2014, containing those 255 avalanches exceeding 0.0125 km^2. Every polygon comes with meta data, including the date of occurrence. This dataset is the underlying dataset to: Wever, N., Vera Valero, C. and Techel, F. (2018) _Coupled snow cover and avalanche dynamics simulations to evaluate wet snow avalanche activity_. Submitted to J. Geophys. Res., in review.瑞士雪崩预警服务机构记录的达沃斯地区湿雪崩多边形数据集。该数据集的地理配准（georeferenced）轮廓同时涵盖雪崩起始区（release area）与堆积区（deposit area），但未对二者进行区分。 本数据集为2011年10月至2014年9月间共计1615条经分类的湿雪崩记录的子集，筛选条件为雪崩面积超过0.0125平方千米，共包含255条雪崩记录。每个多边形均附带元数据（meta data），其中包含雪崩发生日期。 本数据集是以下研究的基础数据集：Wever, N.、Vera Valero, C.与Techel, F.（2018）的论文《耦合积雪与雪崩动力学模拟以评估湿雪崩活动》，该论文已投稿至《Journal of Geophysical Research（J. Geophys. Res.）》，目前处于审稿阶段。
