Solar Radio Emission on Centimeter Waves and Ionization of the E Layer of the Ionosphere
Abstract
It is shown that solar radio emission on any wavelength shorter than 30 cm is good as a solar index for ionospheric studies. The coefficient of correlation between E-layer ionization index and solar radiation decreases to a low value for wavelengths greater than about 30 cm, indicating that a major part of solar X radiation responsible for E-layer ionization originates in the solar atmosphere below the height of origin of 30-cm solar radio emission.
