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..

本数据集包含两台邻近气象站（climate station）在距地面750厘米高度处采集的10分钟采样时长的最大风速对应风向数据（单位：°）。双桅杆气象站（double masted climate station）位于另一台气象站北侧，海拔44米。该时间序列（time series）起始于1995年，已针对双桅杆系统的两组数据集完成质量控制流程。组合时间序列通过计算两台气象站的实测风向的内角平分线得到；当仅有一台气象站产出有效数据时，该站的风向记录将直接复制至最终时间序列中。当对应风速缺失或低于0.05米/秒时，对应风向值将标记为缺失。本数据集同时包含两台邻近气象站在距地面750厘米高度处采集的60分钟采样时长的气温数据（单位标注为%）。双桅杆气象站位于另一台气象站北侧，海拔44米。请查阅随数据集附带的元数据文件（metadata file），以获取该时间序列相关的补充说明。
