本数据集为2011-2020年辛店沟流域雨量站降水观测数据。辛店沟流域位于陕西省榆林市绥德县，属于无定河一级支流。此流域布设试验场一个雨量站，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）。辛店沟流域雨量站基本情况等详见《辛店沟流域2011-2020年情况说明》。

SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge are used for parallel observation. When the self recording rain gauge fails, ordinary rain gauge is used instead. The data include daily precipitation data, precipitation extract data, and the maximum precipitation table of each period (extracted by minutes). For the basic information of wangmaogou watershed and rainfall stations, please refer to the situation description of wangmaogou watershed from 2011 to 2020. </p>\n <p>There are SM1 rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge. SM1 adopts 8:00 and 20:00 two-stage system for annual observation, mainly observing the beginning and ending time of precipitation, and counting the precipitation. 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 is used for flood season observation. In case of failure of self recording rain gauge, the observation data of ordinary rain gauge are supplemented. </p>\n
