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. Please read the metadata file provided with the data for comments related to the data in this timeseries.本数据集包含两处邻近气象站的雪深观测数据，以每3小时一次的3分钟时段平均值形式记录，单位为米（m）。双桅杆气象站坐落于另一处站点北侧，海拔44米（a.s.l.，即海平面以上高度）。该时间序列数据集始于1997年，已针对双桅杆系统的两组观测数据集完成质量控制流程。合并后的时间序列按如下规则生成：当两台传感器数据均完整时，取二者平均值；若其中一台传感器数据缺失，则结合回归分析方法使用另一台传感器的数据。请查阅随数据集附带的元数据文件，以获取本时间序列数据的相关注释说明。
