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.本数据集收录两台邻近气象站在离地750厘米高度处采集的10分钟平均风向数据（单位：°）。双桅杆气象站位于另一台气象站北侧，海拔高度为44米。该时间序列的起始年份为1995年。已对双桅杆系统采集的两台气象站的原始数据集开展质量控制工作。合并后的时间序列通过计算两台测站实测风向的内角平分线得到。若仅单台气象站产出有效数据，则直接将该站的风向记录复制至最终时间序列中。当对应风速数据缺失或低于0.05 m/s时，对应的风向数据将被标记为缺失值。请查阅随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。
