Correction to “Interplanetary magnetic field polarities derived from measurements of the northern and southern polar geomagnetic field”

Abstract

[1] In section 1 of the paper “Interplanetary magnetic field polarities derived from measurements of the northern and southern polar geomagnetic field” by R. Berti, M. Laurenza, G. Moreno, and M. Storini (Journal of Geophysical Research, 111, A06109, doi:10.1029/2005JA011325, 2006), the sentence “In fact, when the IMF is directed toward the Sun (i.e., its polarity is positive), the disturbance field is directed toward the Earth at both poles around the local noon; when the IMF is directed away from the Sun (i.e., its polarity is negative), it is directed away from the Earth at both poles [Svalgaard, 1968; Mansurov, 1969; Mansurov and Mansurova, 1970; Friis-Christensen et al., 1972; Wilcox, 1972].” should be corrected as follows: “In fact, when the IMF is directed toward the Sun (i.e., its polarity is negative), the disturbance field is directed toward the Earth at both poles around the local noon; when the IMF is directed away from the Sun (i.e., its polarity is positive), it is directed away from the Earth at both poles [Svalgaard, 1968; Mansurov, 1969; Mansurov and Mansurova, 1970; Friis-Christensen et al., 1972; Wilcox, 1972].” [2] Leif Svalgaard has kindly pointed out to us that the description of the method he used to infer the IMF polarity from the polar geomagnetic field is now available on the Web site http://www.leif.org/research.
