Snow depth - 180min sample (m)

Snow depth measured on two proximal climate stations as a 3min average every 3 hours (m). The double masted climate station is located north of the station at 44 m a.s.l.. The timeseries starts in 1997. Quality control is performed on both datasets from the double mast system. The combined time series is calculated as an average of the 2 sensors, or if data is missing from 1 sensor the other used in conjunction with a regression.

本数据集为两座邻近气象站的积雪深度观测数据，以每3小时一次的3分钟平均值形式记录，单位为米（m）。双桅杆气象站位于该观测站以北，海拔44米（a.s.l.）。本时间序列的观测起始时间为1997年。双桅杆系统的两套观测数据均已完成质量控制。合并后的时间序列采用两个传感器的观测值均值计算；若其中一枚传感器数据缺失，则使用另一枚传感器数据结合回归分析进行补全。请查阅数据集附带的元数据文件，以获取本时间序列相关的详细注释。
