本数据集为2021-2022年韭园沟流域雨量站降水观测数据。韭园沟流域位于陕西省榆林市绥德县，属于无定河一级支流。雨量站在观测全年降水的基础上，重点观测汛期（6-9月）降水情况。韭园沟流域布设沟口、马连沟、赵家坬、吴家畔、魏家焉、黑家坬、王家坬、王茂庄和蔡家沟9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。韭园沟流域雨量站基本情况等详见《韭园沟流域2021-2022年情况说明》。

Jiuyuangou watershed is located in Suide County, Yulin City, Shaanxi Province, and belongs to the first class tributary of Wuding River. On the basis of observing the annual precipitation, the rainfall station mainly observes the precipitation in the flood season (June September). Jiuyuangou drainage basin is provided with 9 rainfall stations, including Goukou, Maliangou, Zhaojiawa, Wujiapan, Weijiayan, Heijiawa, Wangjiawa, Wangmaozhuang and Caijiagou. DSJ2 siphon self recording rain gauge and SM1 ordinary rain gauge with a diameter of 20cm are used for parallel observation, and ordinary rain gauge is used to replace the self recording rain gauge in case of failure. The data includes the layout map of the basin station network, daily precipitation table, precipitation extract table, and maximum precipitation table in each period. See the Description of Jiuyuangou Watershed from 2021 to 2022 for the basic information of the rainfall stations in Jiuyuangou Watershed

When the intermittent time of precipitation is more than 15 min, it is observed as two precipitation before and after the interval. When the intermittent time is less than 15 min, it is regarded as a precipitation observation record. If a precipitation crosses 8:00 and 20:00, it should be measured at 8:00 and 20:00. Dsj2 adopts 24 segment system for flood season observation. In case of failure of self recording rain gauge, the observation data of ordinary rain gauge are supplemented. </p>\n
