本数据集为1980-1990年王茂沟流域雨量站降水观测数据，王茂沟流域位于陕西省榆林市绥德县，属于韭园沟（无定河一级支流）的一级支流。王茂沟流域共部署王茂庄站一个雨量站。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）。王茂沟流域雨量站基本情况等详见《王茂沟流域1980-1990年情况说明》。

When the intermittent time of precipitation is more than 15 minutes, it is observed as two precipitation before and after the interval, and when the intermittent time is less than 15 minutes, it is recorded as one precipitation observation. If a precipitation crosses 8 hours and 20 hours, it should be measured at 8 hours and 20 hours. Dsj2 type adopts 24 section system for flood season observation.
