    Polar Cap Index Added: 16-02-2007 15:45:29
    Polar Cap Index : The PC index is an index to monitor the polar cap magnetic activity which is mainly caused by changes in the IMF southward component (BZ) and solar wind velocity. Numerous investigations have shwon that the IMF southward component drives ionospheric convection over the polar caps, which is sensed by ground magnetometers responding to the two-cell system of currents flowing in the ionosphere. As the Earth rotates under this two-cell current system, a near-pole station is always located under the sun-aligned part of the system (i.e. a transpolar current). This allows derivation of an index from data obtained at a single near-pole station simply calculating a magnetic horizontal component disturbance along the dawn-dusk meridian. Based on an availability of geomagnetic data from near-pole stations Thule (Greenland, 86.5° geomagnetic latitude) and Vostok (Antarctica, -83.4° ), the new magnetic activity index PC was introduced and studied by Troshichev and Andrezen [Planet. Space Sci., 33, 415, 1985], and Troshichev et al. [Planet. Space Sci., 36, 1095, 1988].

    AMIE derived Indices Added: 16-02-2007 15:44:38
    Assimilative Mapping of Ionospheric Electrodynamics (AMIE)
    The AMIE procedure is an optimally constrained, weighted least-squares fit of electric potential distribution to diverse types of atmospheric observations. This data set represents global geomagnetic indices derived from that model. The model in this case was run using all available magnetometers and a background driven by IMF but no other data even when available. See: A.J. Ridley and E.A. Kihn, Polar cap index comparisons with AMIE cross polar cap potential, electric field, and polar cap area, Geophys. Res. Lett., 31, doi:10.1029/2003GL019113, 2004 for more information.

    For more information on AMIE itself:
