本数据集为1986-1990年桥沟流域雨量站降水观测数据。桥沟流域位于陕西省榆林市绥德县，属于裴家峁沟（无定河一级支流）的一级支流。桥沟流域共布设了桥沟1号、桥沟2号、桥沟3号、桥沟4号、桥沟5号和桥沟6号六个雨量站，使用DSJ2型虹吸式自记雨量计和口径为20cm的SM1型普通雨量计进行平行观测，自记雨量计故障时用普通雨量计代替。数据包括流域站网布设图、逐日降水量表、降水量摘录表、各时段最大降水量表（1）。桥沟流域雨量站基本情况等详见《桥沟流域1986-1990年情况说明》。

When the intermittent time of precipitation is more than 15min, it is observed as two precipitation before and after the interval. When the intermittent time is less than 15min, it is recorded as a precipitation observation. If a precipitation crosses 8:00 and 20:00, it should be measured at 8:00 and 20:00.
