Wind direction @ 750cm - 10min average (°)

Wind direction measured on two proximal climate stations at 750 cm above ground as a 10min average (°). The double masted climate station is located north of the station at 44 m a.s.l.. The timeseries starts in 1995. Quality control is performed on both datasets from the double mast system. The combined time series is calculated as the interior bisector of the two measured wind directions. When only one station produces valid data these wind direction records are copied directly to the final time series. Wind directions are set to missing, when the corresponding wind speed is missing or below 0.05 m/s. Please read the metadata file provided with the data for comments related to the data in this timeseries.

本数据集为两台邻近气象站在距地面750厘米高度处采集的风向数据，采样为10分钟平均值，单位为角度（°）。双桅杆气象站位于海拔44米的气象站点北侧。该时间序列起始于1995年。已针对双桅杆系统的两套数据集开展质量控制工作。组合时间序列通过计算两台站点实测风向的内角平分线得到。若仅单台站点产出有效数据，则直接将该风向记录复制至最终时间序列中。当对应风速缺失或低于0.05 m/s时，风向数据将被标记为缺失值。请查阅数据附带的元数据文件，以获取本时间序列相关的数据说明与备注信息。
