黑河生态水文遥感试验:水文气象观测网数据集(阿柔超级站涡动相关仪-2017)
英文标题:HiWATER:Dataset of Hydrometeorological observation network (eddy covariance system of A’rou Superstation, 2017)
  1. 摘要

    该数据集包含了2017年1月1日至2017年12月31日的黑河水文气象观测网上游阿柔超级站的涡动相关仪观测数据。站点位于青海省祁连县阿柔乡草达坂村,下垫面是亚高山山地草甸。观测点的经纬度是100.4643E, 38.0473N,海拔3033m。涡动相关仪的架高3.5m,采样频率是10Hz,超声朝向是正北向,超声风速温度仪(CSAT3)与CO2/H2O分析仪(Li7500A)之间的距离是15cm。

    涡动相关仪的原始观测数据为10Hz,发布的数据是采用Eddypro软件处理的30分钟数据,其处理的主要步骤包括:野点值剔除,延迟时间校正,坐标旋转(二次坐标旋转),频率响应修正,超声虚温修正和密度(WPL)修正等。同时对各通量值进行质量评价,主要是大气平稳性(Δst)和湍流相似性特征(ITC)的检验。对Eddypro软件输出的30min通量值也进行了筛选:(1)剔除仪器出错时的数据;(2)剔除降水前后1h的数据;(3)剔除10Hz原始数据中每30min内缺失率大于10%的数据;(4)剔除夜间弱湍流的观测数据(u*小于0.1m/s)。观测数据的平均周期为30分钟,一天48个数据,缺失数据标记为-6999。因仪器漂移等原因引起的可疑数据用红色字体标识,其中4月13日-4月14日涡动系统Li7500A标定数据缺失;当存储卡存储数据出现问题导致10Hz数据缺失时(2.17-2.23,3.3-4.12),数据由采集器输出的30min通量数据替代。

    发布的观测数据包括:日期/时间Date/Time,风向Wdir(°),水平风速Wnd(m/s),侧向风速标准差Std_Uy(m/s),超声虚温Tv(℃),水汽密度H2O(g/m3),二氧化碳浓度CO2(mg/m3),摩擦速度Ustar(m/s),奥布霍夫长度L(m),感热通量Hs(W/m2),潜热通量LE(W/m2),二氧化碳通量Fc(mg/(m2s)),感热通量的质量标识QA_Hs,潜热通量的质量标识QA_LE,二氧化碳通量的质量标识QA_Fc。感热、潜热、二氧化碳通量的质量标识分为三级(质量标识0:(Δst <30, ITC<30); 1: (Δst <100, ITC<100); 其余为2)。数据时间的含义,如0:30代表0:00-0:30的平均;数据以*.xls格式存储。
