摘要

The results of recording the intensity of low-frequency electromagnetic emissions at altitudes of the outer ionosphere based on satellite data at various levels of solar activity have been investigated. The intensity of low-frequency emissions has been found to depend on the solar activity, i.e., the spatial noise characteristics vary. Mean values of the noise amplitude variations at various phases of the solar activity cycle are presented. The low-frequency emissions are shown to serve as a source of information about the processes in the surface plasma; in particular, the state of the radiation belts is judged from them. The noise carries information about the variations in the particle fluxes intruding into the Earth's plasmasphere under various solar activity conditions and about the magnetospheric plasma variations related to the growth of solar activity. In other words, the electromagnetic low-frequency noise can be a peculiar kind of indicator of the solar activity and the state of the magnetosphere. [PUBLICATION ABSTRACT]
