红山台磁通门磁力仪观测数据对比分析

CONTRASTIVE ANALYSIS OF FLUXGATE MAGNETOMETER OBSERVATION AT HONGSHAN SEISMIS STATION

  • 摘要: 对2010-2012年红山地磁台2套相同厂家和型号的磁通门磁力仪GM4-1和GM4-2产出的数据进行背景噪声、基线值、预处理分数据和日均值几个方面的对比分析。结果显示:(1)两套仪器各分量日均值变化曲线形态一致性较好;(2)GM4-2各分量的噪声值和月剩余标准差值均大于等于GM4-1各分量的噪声值。(3)GM4-2仪器相对于GM4-1仪器灵敏度较低。分析的结果能较好地反映出2套仪器观测数据的内在质量,也能客观地反映出红山台各套仪器的工作状态及绝对观测对相对记录的控制水平。

     

    Abstract: Based on 2010-2012 observation at Hongshan seismic station,this paper compared background noise,baseline value,pre-processing sub-data and daily mean of the fluxgate magnetometer GM4-1 and GM4-2 which are the same manufacturer and model.The results show that: (1)the daily average change curves of each compound of the two sets of instruments are well consistent with each other; (2)the noise value and residual standard deviation values of each component of GM4-2 are greater than or equal to that of GM4-1; (3)The instrument sensitivity of the GM4-2 is lower than that of the GM4-1.
