Biography:
He was born on January 15, 1928 in the Leninsky village (according to other sources, the village of Lenino village) of the Moscow region of the Russian SSR.
During 1935-1941 he studied at the Moscow school, during 1941-1943 he tried to evacuate in the Kazakh Samaarkand city, in 1945 he graduated from the school in Moscow City.
During 1945-1950 he was a student of the Physics Department of M. V. Lomonosov Moscow State University.
During 1950-1957 he worked at the Crimean Astrophysical Observatory: laboratory assistant, graduate student, scientific secretary, junior researcher (according to some sources, he worked in Simeiz city since 1952).
During 1957-1985 he worked at the Institute of Applied Geophysics of the USSR Academy of Sciences, first as a junior researcher, later head of the laboratory, head of the IZMIRAN department in 1985-2016, deputy director, then chief researcher.
In 1954 he defended his dissertation for the degree of Candidate of Physical and Mathematical Sciences.
In 1958 he received the title of senior non-scientific associate.
In 1966 he became a doctor of physical and mathematical sciences.
He was a member of the Bureau of Radio Wave Propagation, was chairman of the Soviet National Committee for the Study of Global Ionospheric-Thermospheric Relations, and was a member of the International Astronomical Union, the International Association for Geomagnetism and Aeronomy, and the Eurasian Astronomical Society.
He received the title of "Honored Scientist of the RSFSR".
He is a laureate of the USSR State Prize.
Later, the professor became an employee of the M. V. Pushkov Institute of Earth Magnetism, Ionosphere and Radio Wave Propagation of the Russian Academy of Sciences.
He died on January 19, 2016 in Moscow City.
World-class specialist in the study of the Sun and solar-terrestrial physics. He developed a new direction of research in the field of solar-terrestrial physics, studying the short-wave radiation of the Sun, the dependence of its spectrum and intensity on the phase of the solar cycle. He conducted a series of works on the theory of ionosphere formation based on the consideration of elementary processes and modeling of the conditions of ionization of the Earth's upper atmosphere by ionizing radiation of the Sun. Attaching great importance to experimental data, he organized a team of employees of the Institute of Applied Geophysics to create domestic equipment and conduct direct measurements of the short-wave ultraviolet region of the solar spectrum on rockets and satellites. A series of instruments has been created, measurements have been made on meteorological rockets and artificial satellites of the Earth, and this work is continuing. He participated in many expeditions on missile launches and led a scientific project of the Soviet-American experiment - the JASPIC project during 1978-1979 on the intercalibration of missile measurements on the research ship "Professor Vizi" in the Atlantic Ocean. He was one of the organizers of the ionospheric service, which later became the heliogeophysical service of the Institute of Applied Geophysics. He created a scientific school to study and model variations of the ionosphere not only of the Earth. He was awarded the title of Laureate of the USSR State Prize for his work on the study of the ionosphere of the planets Mars and Venus. Since the 80's, together with his students and colleagues, he studied the impact of solar and geomagnetic activity on the ionosphere and other geophysical processes, atmospheric dynamics, processes in the biosphere. A series of works on the study and analysis of solar and ionospheric quasi-biennial variations has been performed.
In particular, the heliolongitious effect of variations was revealed, the spatial connections of the solar magnetic field and heliomagnetic activity were determined. The manifestation of quasi-two-year variations of the total flux of solar radiation in variations of stratospheric wind and speed of Earth's rotation is shown. A group of co-authors developed a new approach to building a model of the Earth's upper atmosphere using satellite local data on the atmosphere, analyzed the impact of solar activity on long-term variations in the density of the Earth's upper atmosphere. A series of joint studies with colleagues on solar activity, including nonlinear sources of acceleration and deceleration of solar activity, as well as studies of the dynamics of global manifestations of the solar cycle and the model of solar magnetic field generation.
The research results have been published in 6 monographs and more than 370 scientific articles. He founded a scientific school for the study of solar-terrestrial physics. He prepared 19 candidates of science, six of his students became doctors of physical and mathematical sciences.
