Fig. 17From: Exploring effects in tippers at island geomagnetic observatories due to realistic depth- and time-varying oceanic electrical conductivityDifference between “December” and “June” \(T_{zx}\) at island observatories, shown as filled circles. “Experimental” and “modeled” differences are colored by light and dark red, respectively. The size of circles below the plots indicates four ranges of differencesBack to article page
