华北平原冬小麦-夏玉米轮作农田通量观测数据集-清华大学位山（高营）站（2005-2006）

该数据集包含了2005年5月17日至2006年9月26日的清华大学位山（高营）站涡度相关系统通量及气象观测数据。站点（116.0542°E，36.6487°N，海拔30m）建于2005年3月18日，地处山东省聊城市茌平区肖庄镇境内，属于位山引黄灌区。气候为暖温带半湿润大陆性季风气候，多年平均气温13.8℃，多年平均降水量为553mm，大部分降水发生在6月至10月之间，多年平均潜在蒸发量为1950mm。站点土壤类型为粉砂壤土，表层5cm土壤饱和含水量为0.43 m3m-3，田间持水量为0.33 m3m-3，凋萎点为0.10 m3m-3。通量塔高10m，下垫面为冬小麦-夏玉米轮种制农田。冬小麦一般在10月中旬播种，次年6月初收割；收完小麦后立即播种玉米，玉米通常在9月底或10月初收割。具体的播种、收割及灌溉日期见数据集中名为Supplementary data_WeishanGaoying20052006.xlsx的文件。

This dataset contains eddy covariance flux and meteorological observation data collected at the Weishan (Gaoying) Station of Tsinghua University from May 17, 2005 to September 26, 2006. The station, located at (116.0542°E, 36.6487°N, 30 m a.s.l.), was established on March 18, 2005, and is situated in Xiaozhuang Town, Chiping District, Liaocheng City, Shandong Province, belonging to the Weishan Yellow River Diversion Irrigation Area. It features a warm temperate semi-humid continental monsoon climate, with a long-term average air temperature of 13.8°C, long-term average annual precipitation of 553 mm (most rainfall occurs between June and October), and long-term average potential evapotranspiration of 1950 mm. The soil type at the station is silty loam; the saturated water content of the 5 cm topsoil is 0.43 m³·m⁻³, field capacity is 0.33 m³·m⁻³, and wilting point is 0.10 m³·m⁻³. The flux tower stands at a height of 10 m, and the underlying surface is a farmland under the winter wheat-summer maize rotation cropping system. Winter wheat is generally sown in mid-October and harvested in early June of the following year; maize is sown immediately after wheat harvest and usually harvested by the end of September or early October. Specific sowing, harvesting and irrigation dates are provided in the file named Supplementary data_WeishanGaoying20052006.xlsx included in this dataset.
