(2011, 2013)。由于仪器故障，大孔径闪烁仪数据缺失的日期为：2019.04.14-2019.04.25；2019.11.02-2019.11.12。\n关于发布数据的几点说明：（1）下游LAS数据以BLS900为主，其次为BLS450，最后为RR-RSS460，最终缺失时刻以-6999标记。（2）数据表头：Date/Time ：日期/时间（格式：yyyy/m/d h:mm），Cn2 ：空气折射指数结构参数（单位：m-2/3），H：感热通量（单位：W/m2）。数据时间的含义，如0:30代表0:00-0:30的平均；数据以*.xlsx格式存储。\n黑河流域地表过程综合观测网或站点信息请参考Liu et al.
