Manual measuring network
收藏资源简介：
The SLF avalanche warning service operates an extensive network of manual measuring sites. The sites are distributed throughout the Swiss Alps and predominantly situated in intermediate altitude zones, between 1000 and 2000 m. Some of the measurement series already span very long periods and are therefore highly valued; the data are also used for climatological and hydrological purposes. The measuring sites are in fixed locations, which are flat and wind-protected. The observers who perform the measurements are trained and paid by the SLF. Data is collected, as far as possible, from the beginning of November until the end of April and after that until half of the measuring site is snow-free. On some measuring sites event-based measurements are also collected during the summer months. If possible, measurements take place between 7 and 7.30 am local time. The following variables are measured at all measuring sites: - snow depth and 24-hour new snow at numerous sites this additional variable is measured: - water equivalent of 24-hour new snow (height of the water column in millimeters, if the new snow sample is melted, without changing the base area) When using the data, please consider and adhere to the associated [Terms of Use](https://www.slf.ch/en/services-and-products/slf-data-service/) To download live data use our [API](https://measurement-api.slf.ch).

SLF雪崩预警服务（SLF）运营着一套覆盖广泛的人工测量站点网络。这些站点分布于整个瑞士阿尔卑斯山区，且主要坐落于海拔1000至2000米的中海拔区域。部分测量序列的时长已相当悠久，因此具备极高的科研价值；该数据集同时可应用于气候学与水文学相关研究。 所有测量站点均为固定布设的平坦防风场地。负责开展测量的观测员均经过SLF培训并获取相应酬劳。数据采集工作原则上于每年11月初启动，至4月底结束，后续延续至半数站点积雪完全消融。部分站点在夏季月份也会开展事件驱动型测量工作。若条件允许，测量于当地每日7:00至7:30间开展。 所有站点均采集以下变量： - 积雪深度与24小时新降雪量 多数站点还会额外采集以下变量： - 24小时新降雪水当量（即新雪样本融化后形成的水柱高度，单位为毫米，测量过程中不改变基底面积） 使用本数据集前，请务必查阅并遵守相关[使用条款](https://www.slf.ch/en/services-and-products/slf-data-service/)。 如需下载实时数据，请使用我们的[API](https://measurement-api.slf.ch)。 如需下载7天前的历史数据，请使用我们的[文件下载服务](https://measurement-data.slf.ch).
