Maximum strength of the atmospheric electric field

Physical Review D, 2021
Particle detectors of the European Space Environment Viewing and Analysis Network (SEVAN) network located on mountain peaks in Aragats (Armenia), Lomnicky Stit (Slovakia), and Musala (Bulgaria) are well suited for the detection of thunderstorm ground enhancements (TGEs).

The Measure of Atmospheric Electric Field

2011
We have developed a prototype of a sensor able to detect and measure electric fields in the atmosphere. The atmosphere is a gaseous envelope gravitationally bound to the Planet. Different atmospheres have very different properties. For instance, the atmosphere of Venus is very thick and cloudy, and is responsible for producing the very high surface ...

An atmospheric electric field meter

Instruments and Experimental Techniques, 2017
The Ryabina atmospheric electric-field meter is described. Results of its comparative tests are presented, which demonstrate that it is superior to its foreign analog, that is, the EFM550 electric-field meter (from Vaisala, Finland), in a number of parameters. The dynamic range of the meter is ±30 000 V/m, the discreteness of measurable values is 1 V/m,

Negative Electric Fields in the Atmosphere

Nature, 1949
ON a number of occasions during the past two years, we have observed a negative electric field (or potential gradient) in the atmosphere close to the earth's surface, when there has been very low stratus cloud (or ‘high-hanging fog'). The importance of this result is that it must involve a process of separation of charge occurring in the cloud and ...

Microsensor for Atmospheric Electric Fields

2020
<p><span>Many phenomena of atmospheric electricity are still not well understood, as most of the processes involved can only be observed in real nature. For this purpose, reliable and stable measurements of the electric field strength are mandatory.

Electric fields in the solar atmosphere

Solar Physics, 1977
The gross-structure of the force-free currents in the solar atmosphere and their possible dynamics have been discussed as caused by quasi short-circuited electric fields, generated by the motion of the solar magnetic features.

Atmospheric response to electric field pulse

Advances in Space Research, 2002
Abstract The complete plasmochemical model was developed for the study of electric field perturbations impact on aeronomy of middle atmosphere and lower ionosphere. The model includes the following set of processes: dissociation, dissociative recombination and dissociative ionization, ionization, excitation, electron attachement and detachement ...

Electric Fields in the Middle Atmosphere

Physica Scripta, 1987
Middle atmospheric electrodynamics is characterized by discussing the present understanding of the background electrical conductivity and the sources for electric fields and currents within the medium. Results of recent research that contradicts the historical view of the region are presented. Of principal interest to the present direction of the field

Electric fields in the solar atmosphere: A review

Solar Physics, 1991
A review is presented of remote sensing techniques which measure the electric field component transverse to the line of sight and achieve a sensitivity range of 5-10 V/cm. Three models are shown to predict quasistatic, macroscopic values of E(parallel), the electric field component parallel to the magnetic vector, beyond the sensitivity range ...

Formation of a local atmospheric electric field

Geomagnetism and Aeronomy, 2011
We have estimated the variations in the atmospheric electrostatic field (AEF, EZ(0)) strength in the surface layer caused by variations in conductivity due to radon influences, cosmic ray intensity, changes in the balance of light and heavy ions during sunset and sunrise, and under the effect of the ionospheric electric current potential on the AEF ...
