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厘米处测得的10分钟平均风向（单位：°）。双桅杆气象站位于该站点北侧，海拔44米。该时间序列始于1995年，已针对双桅杆系统的两组数据集完成质量控制。组合时间序列通过计算两个实测风向的内角平分线得到；当仅有一个站点产出有效数据时，该站点的风向记录将直接复制至最终时间序列中。若对应风速缺失或低于0.05 m/s，则将对应风向设为缺失值。请阅读数据集附带的元数据文件，以获取该时间序列数据的相关注释说明。
