<p>This data set is the precipitation observation data of Qiaogou watershed in the first sub region of Loess Hilly and gully region from 2011 to 2020. 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 of rainfall station, precipitation extract data and maximum precipitation table of each period (extracted by minutes). For the basic information of Qiaogou basin and rainfall station, please refer to the situation description of Qiaogou basin from 2011 to 2020. </p>

<p>Instrument continuous observation manual timing observation</p>
<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>
<p>In the process of observation, when there is an abnormal value in the self recording rain gauge, the observation value of the ordinary rain gauge is used for interpolation and verification; in the process of data entry, there are four levels of manual verification, which are tabulation, primary calibration, recalibration and audit, to ensure the data quality. </p>
