Concerning System Earth During Geomagnetic Polarity Transitions: Atmospheric Ionisation effects
Abstract
Precipitating solar energetic particles ionize the atmosphere. We present a numerical model to determine ionisation rates for protons, electrons and heavier particles in individual solar energetic particle events and on longer time scales. Changes in ionisation rates with varying geomagnetic field and varying levels of solar activity (solar cycle, Gleiss berg cycle, longer time scales) are discussed. From this analysis, conditions for efficient ionisation of the atmosphere will be derived.
