If the power of the disturbing wave is very large, ‘self-demodulation’ is accompanied by ‘self-distortion’ effects because of the large change in collision frequency distorting the original wave form of the

The Photochemistry of the Mesospherey processes that takes place in the lower thermosphere since some species, which are produced in the lower thermosphere, are brought into the mesosphere by eddy diffusion. It is therefore convenient to include heights up to 110–100 km when photochemical processes in the mesosphere are considered. In

Ionizing Radiation Affecting the Lower Ionosphered magnetospheric sources. Variations in the energy input to the earth’s atmosphere from these sources have been observed for nearly a half-century by means of a variety of ground based measurements including VLF (3–30 kHz) radio transmissions (e.g. Espenshied 1926; Lauter 1950, 1961; Bracewell et al

However, according to Crain and Booker (1964) and Thomas (1969) the effects of ions on VLF and ELF wave propagation may be significant during disturbed conditions such as a PCA or auroral absorption event. Cole and Pierce (1965) found that the dominant influenc

This plasma component of the air is essential for the conversion of kinetic energy of the gas into electromagnetic energy. Electromagnetic energy can be transported within the various height regions and ultimately will be dissipated through Ohm losses. Thus, the
