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.

本数据集记录了两台邻近气象站在地面以上750厘米处采集的10分钟平均风向（单位：°）。双桅杆气象站坐落于另一台气象站北侧，海拔44米。该时间序列始于1995年，双桅杆系统的两组数据集均已完成质量控制。最终合并的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，则直接将该站点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风速低于0.05 m/s时，对应的风向数据将被标记为缺失值。有关本时间序列数据的详细说明，请查阅随数据集附带的元数据文件。
