本数据来自大野口流域关滩森林站超级样地，该超级样地乔木植被为青海云杉纯林，样地大小为100m×100m。观测详细内容如下：\n观测时间：2008-06-01至2008-12-31日每天下午18:00，如果当天有降雨的话，会在降雨结束后观测一次。 若Lysimeter下的集雨器内有透过雨量，则要测量该透过雨量。 \n观测地点：大野口关滩森林站森林水文试验样地。 \n观测内容：\n1）对照的大气降雨，有两个雨量筒同时观测， 布设在水文试验样地附近平缓的河滩上。 \n2）林内穿透降雨，在样地内共布设了20个雨量筒，布设的依据是雨量筒上方的冠层郁闭度。 \n3）每天18:00的Lysimeter重量。 \n4）Lysimeter下面集雨器的透过雨量。\n观测仪器：\n1）标准20cm直径雨量筒量雨器。\n2）自制Lysimeter（直径20cm；共4个；土壤植被各不相同）。\n3）电子天平（精度0.1g），用于观测自制Lysimeter的重量变化。
