Datasets description

This data set is the precipitation observation data of wangmaogou watershed from 1964 to 1979. Wangmaogou watershed, located in Suide County, Yulin City, Shaanxi Province, is a tributary of Jiuyuangou (the first tributary of Wuding River). A rainfall station of wangmaozhuang station is set up in wangmaogou watershed. SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon 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 of rainfall station, precipitation extract data and maximum precipitation table of each period (extracted by minutes). The situation of rainfall stations is shown in the basic information table of Jiuyuangou basin. Due to historical reasons, the survey was stopped in 1970-1973.

Data source description

Instrument continuous observation, artificial timing observation.

Data processing method

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 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.

Data quality description

In the observation process, when the abnormal value of the self recording rain gauge occurs, the ordinary rain gauge observation value is used for interpolation and verification; during the data entry process, four levels of manual verification are carried out, including tabulation, primary calibration, re calibration and audit, so as to ensure the data quality.
