Long wave incoming radiation @ 200 cm - 5min average (W/m2)

Long wave incoming radiation (wavelengths of 5 to 50 µm) measured on two proximal climate stations at 200 cm above ground as a 5min average (W/m2). The double masted climate station is located between Badesø and Langsø at 40 m a.s.l.. The timeseries starts in 2008. 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.5至50微米波长的下行长波辐射（Long wave incoming radiation），于距地面200厘米高度的两台近地气候站开展观测，以5分钟平均值作为统计指标，单位为瓦每平方米（W/m²）。双桅杆气象站位于巴德瑟（Badesø）与朗瑟（Langsø）之间，海拔40米。该时间序列起始于2008年。已对双桅杆系统的两套数据集完成质量控制。合并后的时间序列通过两台传感器的观测值平均计算得到；若其中一台传感器数据缺失，则采用另一台传感器数据结合回归分析进行补全计算。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的详细注释信息。
