本数据集为2025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。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2025年情况说明》。观测指标为降水量（mm）。

In case of failures with the automatic rainfall gauge, data from the ordinary rainfall gauge will be used as a supplement. The main task is to measure the start and end times of precipitation events, and to record the amount of precipitation. If there is a pause between precipitation events lasting more than 15 minutes, those pauses will be recorded as two separate precipitation events. If the pause is less than 15 minutes, it will be recorded as a single precipitation event.
