| Zusammenfassung |
| The contribution of magnetospheric current
systems to geomagnetic daily variations is analyzed by means of a spherical
harmonic analysis (SHA) using elementary models as well as the Tsyganenko model
of the magnetosphere. It is discovered that the magnetospheric contribution to
some SHA coefficients is much higher than the known average value of about 20%,
especially when considering non-local time terms and solstitial conditions. |
