Abstract：Using the water temperature observations sampled in minute rate at the Ning-Jin-Ji Well 22 station,data features,such as daily average,short time average,and their corresponding ranges and standard deviations are calculated,and the calculated features are analyzed.The results suggest that:(1)Performance of observation instruments can affect final measurements;(2)Performance in the real observation environment may differ from that in the laboratory,resulting in incompetence with the requirements of the real observation environment;(3)The different performances of each instrument can be obtained through the calculation and analysis of a large number of observations,therefore observations can be used to infer instrument performance differences.The data analysis cases shown in this paper provide a research idea that performance of the instrument can be analyzed by using a large amount of data.
