Solar Cosmic Rays in the Geosphere
As well-known, during solar flares in terrestrial environments the very complex events and processes occur. They are due to the entire spectrum of solar ionizing radiation, including ultra-violet emission, X-rays and fast particle fluxes. In particular, there are some observational evidence of radio burst generation at ionospheric levels in the ultra-short wave range, at the frequency of 550 ± 40 MHz (e.g., Musatenko, 1980). Mechanism(s) of radio emission of near-Earth space at the frequencies much more high in comparison with the characteristic frequencies of ionospheric plasma are not yet well developed. Meanwhile, one of the contributors of this effect seems to be fast electrons from solar flares.
