Fig. 1.From: Solar cycle dependence of quiet-time magnetospheric currents and a model of their near-Earth magnetic fieldsLong-term variation of magnetospheric field component in GSM coordinates. Annual means of the −ZGSM component as derived from CHAMP data (crosses); model prediction of the −ZGSM component (full line). Error bars reflect the RMS difference between CHAMP and Ørsted annual means.Back to article page
