AG2.0型超声波蒸发传感器遇低温结冰时记录的处理

Records processing for AG2.0 ultrasonic evaporation sensor in case of freezing at low temperature

文章分析了3a马尔康国家基准气候站AG2.0型超声波蒸发传感器观测数据,结果表明:蒸发传感器遇低温结冰时段自动观测数据偏大。对1d中部分时间段内蒸发水结冰、融化以及冬季全天结冰期很短的观测数据进行了分析,分析认为数据偏大主要是因为蒸发桶和测量筒的材料物理性质以及测量的水体面积不同。最后提出了数据记录处理建议。

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.
