Book Description
According to the provisions of the surface atmospheric electricity theory, the space charge of the surface air layer owes its origin to ionization by exhaling soil radon. According to field observations, a model representation of relations between hydrogen, methane, radon, and surface atmospheric electricity elements is composed. Bubbles of two volatile gases carry soil radon from a depth of 4-6 m to the near-surface atmosphere. As a consequence, light ions produced by ionization determine polar conductivity of the surface air; light ion aggregation with neutral condensation nuclei produces heavy ions primarily responsible for the atmospheric electric field. This means that the surface atmospheric electricity is determined by local geology and geodynamics.According to the field observations, the radon content in the surface soil layers is at least two orders of magnitude higher than the concentration of ionizer exhalation. A change in the soil radon content of a single percent will lead to a twofold change in the exhalation concentration, i.e., to a twofold change in the polar conductivities and the atmospheric electric field. This means that the surface atmospheric electricity elements will be extremely sensitive to variations in the subvertical carrier gas (hydrogen and methane) flow density.The results of multiple field observations prove the correctness of the above assumptions. The increased soil-atmosphere air exchange above fault zones, the basement top settling area, and the zones of natural or human-made soil loosening leads to an abrupt decrease in the atmospheric electric field and an increase in the polar air conductivity. An increase in the sub-vertical flow density of hydrogen above the ore body cap or methane in the oil field plume inevitably leads to low values of the atmospheric electric field within the deposit boundaries. The effect can be increased by the presence of natural or human-made seismic excitation in geological environments.The industrial level withdrawal of artesian waters is accompanied by a multiple increase in the atmospheric electric field above the area of hydrogeological processes; methane injection into the underground gas storage, industrial disposal of industrial wastewater leads to the opposite effect, i.e., a decrease of the atmospheric electric field. Taking into account the model constructed, complex measurements of surface atmospheric electricity elements--hydrogen and radon--allow for an indirect expression estimate of the soil methane content above the level of (10-6 - 10-5) vol.% and monitoring of the landslide stressed state.

Book Description
Electromagnetic Waves, Volume 14: VLF Radio Engineering provides a detailed coverage of the fields involved in very low frequency (VLF) radio engineering. This book serves as a guide for applying the information in the solution of practical problems. Comprised of seven chapters, this volume starts with an overview of the communications aspect following the flow of information carrying energy from the transmitting to receiving locations. This text then presents the complete systems that consider the interrelationship of the various factors. Other chapters explain the basic concept of a VLF antenna, which is a vertical electric monopole over a perfectly conducting flat plane. This book discusses as well the radio wave propagation at VLF, which has been studied theoretically and experimentally for many years. The final chapter deals with the primary components of a complete VLF radio system. This book is a valuable resource for radio engineers, scientists, and researchers.

Book Description
Atmospheric Electricity, Second Edition provides a comprehensive discussion of the various aspects and areas of concern in atmospheric electricity. The book limits its concerns to the essential and unique topics that are relevant to the general problems in atmospheric electricity. The text first presents historical survey atmospheric electricity, and then proceeds to covering the general principles involved in atmospheric electricity. The subsequent chapters cover the much more specific and technical concepts, such as the separation of charge; the lightning discharge; the transfer of charge; the vertical potential gradient; and ions and nuclei. The title will be of great use to students, researchers, and practitioners of disciplines related to meteorology.

Book Description
The major emphasis of this book is on physical mechanisms and sources of the ULF/ELF natural electromagnetic fields noises. In the course of this text, some of these mechanisms of magnetospheric origin will be treated in detail and others in a more sketchy fashion, while the global electromagnetic resonances excited by lightning activity and other sources are the priority. The interested reader is referred to the books cited in the text for details about the ULF/ELF fields of magnetospheric origin. Much emphasis is put on studies of electromagnetic phenomena caused by rock deformation/fracture including the ULF/ELF effects possibly associated with tectonic activity, earthquakes and other natural disasters. One of the challenges of this research is to fully understand electromagnetic effects and physical processes in the rocks deep in the Earth’s crust.
