Abstract：This paper analyses the observation data of AG2.0 ultrasonic evaporation sensor of Maerkang national benchmark climate station in recent 3 years.The results show that the automatic observation data of evaporation sensor during freezing time are larger.The observational data are analyzed on the freezing and melting of evaporated water during part of the day and the very short freezing period throughout winter.The analysis shows that the bulk of the data is mainly caused due to the physical properties of the material in the evaporating barrel and the measuring barrel as well as the difference in the area of the measured water body.Finally,suggestions on data record processing are put forward.
