本数据集为2021-2022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。王茂沟流域共布设了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。王茂沟流域雨量站基本情况等详见《王茂沟流域2021-2022年情况说明》。

When the self recording rain gauge fails, it is replaced by an ordinary rain gauge. The data includes the layout map of the watershed station network, daily precipitation table, precipitation extraction table, and maximum precipitation table for each time period.
