We have studied the maps of radio active mineral distribution in Earth, Moon and Mars obtained from in situ and remote sensing observations. The distribution of U and Th in these rocky planets show some interesting features in association with internal heat distribution and volcanism. The results of our studies will be helpful for mining , space exploration and understanding the...
The Earth Planetary (or Bond) albedo is one of the crucial indicators of the Earth system energy budget. State-of-the-art approach to estimate the Earth Bond albedo is by processing satellite measurements of the Earth outgoing short-wave radiation. An exceptionally large albedo values (up to $0.35$ daily maximum) in December 2020 were obtained using the data by Earth Polychromatic Imaging...
Atmospheric aerosols significantly affect human health and climate change. These particles have a strong impact on the energy balance in the Earth`s atmosphere. At the same time, intense aerosol contamination causes different diseases and decreases life quality. Therefore, many countries and cities already have systems and networks for monitoring air quality. The quantitative characteristics...
The theme of the research project: "Antarctic tropopause over the station Marambio in the conditions of the ozone hole during 2004-2019". The object of study is the polar tropopause of the Southern Hemisphere. The subject of the study is the change in the height of thermal and ozone tropopauses in the ozone hole. The aim of this work is to improve the understanding of the distributions and...
Comprehensive low-frequency multispacecraft wave study of flapping current sheet oscillations in the Earth's magnetotail with different morphologies of oscillation behavior was carried out. Measurements from the Magnetospheric Multiscale (MMS) mission during 2020/08/26 were analyzed. Comparison of the results calculated by methods of phase difference, wave surveyor and Multipoint Signal...
The problem with penetration of the ULF electric field, exited by the current source in the atmosphere, into the upper ionosphere is investigated both within the dynamic and the quasi-electrostatic approach. It had been shown that (1) both approaches yield practically similar results for the penetration of the electric field in the case of closed geomagnetic field lines; (2) in the case of...
