This dataset contains precipitation observation data from the Wangmaogou watershed rainfall station in 2023. The Wangmaogou watershed is located in Suide County, Yulin City, Shaanxi Province, and is a first level tributary of Jiuyuangou (a first level tributary of Wuding River). A rainfall station named Wangmaozhuang has been set up in the Wangmaogou watershed, using DSJ2 siphon type self recording rain gauge and SM1 ordinary rain gauge with a diameter of 20cm for parallel observation. 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 period. The basic information of the rainfall station in Wangmaogou Basin can be found in the "Explanation of the Situation in Wangmaogou Basin in 2023"

Continuous observation by instrument and regular observation manually
Precipitation observation instruments include DSJ2 siphon self recording rain gauge and SM1 ordinary rain gauge with a diameter of 20cm. The DSJ2 self recording rain gauge adopts the 24 segment system for flood season observation, and the SM1 ordinary rain gauge adopts the 8:00 and 20:00 two segment system for annual observation. In case of failure of the self recording rain gauge, the observation data of the ordinary rain gauge shall be used for supplement. The starting and ending time of precipitation is mainly observed, and the precipitation is counted. When the interval time of precipitation is more than 15min, it is observed as two times of precipitation before and after the interval time. When the interval time is less than 15min, it is recorded as a precipitation observation. If a precipitation exceeds 8 and 20 hours, it should be added at 8 and 20 hours
The recording rain gauge shall be calibrated before the start of observation every year. In the process of data entry, there are four levels of manual verification: tabulation, initial verification, re verification, and audit to ensure data quality
