The effective estimation of the missing values of time series data at the scale of point process could improve its data quality. The meteorological and hydrological data sets (daily maximum air temperature, daily minimum air temperature, daily solar radiation, daily rainfall and daily stream flow) were collected through the long-term field experiments in a typically small subtropical watershed in subtropical zone. The performance differences within five interpolation methods of linear interpolation method(LIM), K-Nearest neighbor interpolation ...
