Wind direction at max wind speed @ 750cm - 10min (°)

Wind direction at maximum wind speed measured on two proximal climate stations at 750 cm above ground as a 10min sample (°). 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. Air temperature measured on two proximal climate stations at 750 cm above ground as a 60min sample (%). The double masted climate station is located north of the station at 44 m a.s.l..

本数据集包含两类观测数据：其一为以10分钟为采样周期，在地面以上750厘米高度处测得的两处邻近气象站的最大风速对应风向数据，单位为角度（°）。双桅杆气象站位于该站点以北，海拔44米（above sea level，a.s.l.）。该时间序列起始于1995年，已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处实测风向的内角平分线得到；若仅一处气象站产出有效数据，则直接将该站点的风向记录复制至最终时间序列中。当对应风速缺失或低于0.05 m/s时，风向数据将被标记为缺失值。其二为以60分钟为采样周期，在地面以上750厘米高度处测得的两处邻近气象站的空气温度数据，单位为百分比（%）。双桅杆气象站位于该站点以北，海拔44米（above sea level，a.s.l.）。请查阅随数据集附带的元数据文件，以获取该时间序列相关数据的注释说明。
