大气电场仪是测量大气电场的重要设备,其测量结果受多种因素影响.通过一系列对比试验表明:电场仪采用探头正置或倒置结构时的观测结果基本一致,倒置结构有利于避免雨水带来的影响.不同的安装环境对测量结果的影响很大,为了消除这种影响,提出了对观测数据进行地面修订的方法,得到不同天气条件下的修订系数.所得结果对于实现多站电场仪联网观测的数据一致性有重要实际意义.
Atmospheric electric field instrument is an important equipment to measure atmospheric electric field and its measurement results are affected by many factors.A series of comparative experiments show that the observation results of the electric field instrument when the probe is in the upright or inverted structure are basically the same and the inverted structure is helpful to avoid the rainwater zone In order to eliminate this kind of influence, a method to modify the observational data on the ground is proposed, and the revised coefficients under different weather conditions are obtained.The results obtained are very helpful to realize the multi-station electric field instrument Data consistency of networked observations has important practical significance.
