PC Index

Oleg Troshichev and Alexander Janzhura

SPACE WEATHER MONITORING BY GROUND-BASED MEANS: PC IndexSpace Weather Monitoring by Ground-based Means demonstrates that, when estimated properly, the magnetic activity in the polar cap is an adequate indicator of the solar wind energy that enters into the magnetosphere. As a result, the polar cap magnetic activity index PC starts to grow prior to the onset of the magnetospheric substorms and magnetic storms, and intensity of the magnetospheric disturbances is successfully estimated by the PC growth rate.

The book discusses the fact that the polar cap magnetic activity is very sensitive to geoeffective changes of the solar wind parameters and, as a result, can be used to monitor solar wind variations and their effect on the magnetosphere, i.e. solar weather. It describes new and reliable methods of space weather monitoring and shows how the unified procedure provides consistent data from northern and southern polar regions irrespective of the UT time, season, and solar cycle.
