Abstract:
The atmospheric electric field Ez is the most urgent problem of study of the physics of the atmosphere and the
processes occurring in it. The conducted studies show the relationship of the electric field with atmospheric
processes. Monitoring its changes is necessary to solve practical problems. This article presents brief
characteristics of the installation of the EFM-100 electrostatic fluxmeter of the scientific cosmophysical
experimental complex at the L.N. Gumilyov Eurasian National University (ENU) and its experimental data
obtained in 2020. The article presents the results of observation of atmospheric-electrical characteristics near
the Earth's surface and monitoring of the electric field of the atmosphere of the city of Nur-Sultan, in
particular, estimates of the variation of the electric field of the surface layer of the atmosphere during sunrise
and sunset based on data obtained by the EFM-100 fluxmeter. The comparison of meteorological data with
the data of the electric field strength of the atmosphere is given. The analysis of the days and months in
September and October 2020, when the conditions of “good weather” were manifested, was carried out. The
series of electric field data obtained at other measuring stations show the characteristic periodicity of the
electric field behavior. It is established that the value of the atmospheric electric field increases during sunrise
with the manifestation of the solar terminator effect. It is interesting to study the relationship between the
magnitude of the electric field of the atmosphere and the intensity of the cosmic ray flux, especially in the
case of Forbush effects. The data of the ENU ground-based experimental complex allows us to conduct
research on the study of atmospheric physics, including atomic electricity, as well as their interaction with
cosmic rays and meto-conditions.
