Scientific relations
The lab of radio sounding of the ionosphere has scientific relations with the Institute of applied geophysics named after academician E. K. Fedorov (Moscow), and the Research Institute of radio physics (RIRP, Nizhni Novgorod) within the Federal principal program “Creation and development of the geophysical system for monitoring of geophysical conditions over the territory of RF for 2008-2015”.
The lab keeps up and expands scientific cooperation with RIRP (Nizhni Novgorod), Russian Institute for Powerful Radiobuilding (RIPR, St.-Petersburg), University of Tromso, (Norway), and international scientific organization EISCAT in the study of the effects of ionosphere modification by powerful HF radiation.
The lab closely cooperates with the chair of atmospheric physics of the physical department of the Moscow State University named after Lomonosov (Moscow) in conducting joint experiments, data exchange, data processing, and interpretation of the results.
Studies of the ionosphere modified by HF radiation have been performed together with scientific researchers from the Physical Institute named after P. N. Lebedev (RAS, FIAN, Moscow).
The lab keeps up scientific collaboration with the Murmansk State Technical University (MSTU, Murmansk) in the interpretation of the results and analysis of dynamics of ionospheric structures by comparison of tomographic reconstruction pictures of ionospheric electron density spatial distributions with the results of numerical simulations.
In the years 1997-2002, 2003-2006, 2007-2012 the lab was a partner of the Norwegian-Russian program of the study of the upper atmosphere within the agreement on scientific-technological cooperation in Arctic and exploration of the North between the Federal Agency on science and innovations of RF and Research Council of Norway. Within this program, the cooperation with the University of Tromso, Auroral observatory of Tromso, and University center on Svalbard (UNIS) has been keeping up.
The scientific researchers of the lab have common publications with the colleagues from the Institute of Space and Atmospheric Studies, University of Saskatchewan (Saskatchewan, Canada), and University of Leicester (Leicester, England).
Plans for the nearest future
