Calculation of conductivities and currents in the ionosphere

V. W. J. H. Kirchhoff, Lynn A. Carpenter

Abstract

Formulas and procedures to calculate ionospheric conductivities are summarized. Ionospheric currents are calculated using a semidiurnal E-region neutral wind model and electric fields from measurements at Millstone Hill. The results agree well with ground based magnetogram records for magnetic quiet days.
