| Abstract: | In order to investigate quantitatively the accuracy of geomagnetic daily variation recorded by FGE magnetometer, we analyze the stability and precision of some groups baseline values continuously recorded one day at seven observatories in 2009. The results show that the standard deviation and variable amplitude of the baseline values are small in D, H and Z components. Then we select the baseline values continuously recorded one day at CDP and KSH observ- atories in 2009 and 2010, and analyze the influence of absolute measurement intervals on the stability of the baselines. |
