This data set is the precipitation observation data of xindiangou Basin Rainfall Station from 1954 to 2010. The SM1 type ordinary rain gauge with a diameter of 20cm and dsj2 type siphon type self recording rain gauge are used for parallel observation. When the self recording rain gauge fails, the ordinary rain gauge is used instead. The data include the layout of observation station network in xindiangou basin and the distribution map of soil and water conservation measures, daily precipitation data, precipitation excerpt data, maximum precipitation table in each period (excerpt by minute). See the basic situation of rainfall stations in xindiangou basin for the situation of rainfall stations.

Instrument continuous observation Artificial timing observation
Precipitation observation instruments include SM1 ordinary rain gauge with a diameter of 20cm and dsj2 siphon type self recording rain gauge. The SM1 type adopts the 8-hour and 20-hour two-stage system for annual observation, mainly observing the starting and ending time of precipitation, and making statistics of precipitation. When the intermittent time of precipitation is more than 15 minutes, it is observed as two precipitation before and after the interval, and when the intermittent time is less than 15 minutes, it is recorded as one precipitation observation. If a precipitation crosses 8 hours and 20 hours, it should be measured at 8 hours and 20 hours. Dsj2 type adopts 24 section system for flood season observation. In case of failure of self recording rain gauge, the observation data of ordinary rain gauge is used for supplement.
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.
