Investigation of The Atmosphere and Ionosphere by The Radiophysical Measuring Complex of The “Mikhnevo” Geophysical Observatory

A study of appearance and spatio-temporal dynamics of disturbances of the atmosphere, the upper and lower ionosphere, require of integrated investigations of interrelated processes at different altitudes and in different geophysical conditions. In the observatory of IDG RAS "Mikhnevo" created the unique radiophysical complex, allowing to carry out of coordinated measurements of variations of the geomagnetic field, propagation of SW, LW and VLF radio signals, variations of electric fields and atmospheric currents. Analysis of the data of measurements of the total electron content of the ionosphere with phase and amplitude of the signals of LF-VLF range on global and regional routes allows to obtain data on the features of the structure and dynamics of the ionospheric plasma in the mid-latitude zone of the European part of the Russian Federation. The coordinated analysis of GNSS and VLF signals makes it possible to study the mechanisms of the relationship between the perturbations of the upper and lower ionosphere and the dynamics of the ionosphere in the horizontal and vertical directions.
