基于RBD式自动气象站大型蒸发传感器气泡排除法

Bubble elimination for the large-scale evaporation gauge of automatic weather station based on RBD

文章以AG2.0型超声波蒸发传感器为例,分析其在黄石国家基本气象站运行期间遇到的数据异常问题。从蒸发测量原理、蒸发传感器的构成等方面剖析问题形成的原因,并给出解决方案与思路。特别指出因气泡而引起的蒸发数据异常的现行处理方法的不足,同时给出了自创的、更高效的RBD式大型蒸发气泡排除方法。

Taking AG2.0 ultrasonic evaporation gauge as an example, this paper analyses the problem of abnormal data during the operation in Huangshi National Basic Weather Station. The causes of the problem are analyzed from the aspects of measurement principle and the constitution of the evaporation gauge. And its solving treatment and idea are given out. The deficiencies of the current processing methods for abnormal evaporation data caused by the bubble are specifically pointed out. Meanwhile, the bubble elimination for the large-scale evaporation gauge based on self-created and more efficient RBD method is also given out.
