Air temperature, 200cm @ 30min sample (°C)

Air temperature measured on two proximal climate stations at 200 cm above ground as a 30min sample (°C). The double masted climate station is located north of the station at 44 m a.s.l.. The timeseries starts in 2009. Quality control is performed on both datasets from the double mast system. The combined time series is calculated as an average of the 2 sensors, or if data is missing from 1 sensor the other used in conjunction with a regression. Please read the metadata file provided with the data for comments related to the data in this timeseries.本数据集为两个邻近气象站离地200厘米高度处测得的气温数据，采样间隔为30分钟，单位为摄氏度（°C）。该双桅杆气象站位于另一气象站北侧，海拔44米。该时间序列起始于2009年。双桅杆系统的两套原始数据集均已完成质量控制。组合后的时间序列通过计算两个传感器的观测均值得到；若其中一个传感器数据缺失，则采用另一传感器的数据结合回归分析进行补全。请参阅随数据集附带的元数据文件（metadata file），获取该时间序列数据的相关注释说明。
