Fig. 1From: Data agreement analysis and correction of comparative geomagnetic vector observationsInfluence characteristics of the attitude angle and scale factor in the morphology of comparative geomagnetic observations. The figure shows the daily geomagnetic variation and vector difference on June 17, 2020, at the Yunlong (YUL) observatory. Because of the heading angle deviation, the difference, dH, has a similar morphological change to the D component. Because of the scale factor, the dD and dZ differences are similar to the morphological variations of the D and Z components, respectivelyBack to article page
