Studies of the dayside ionosphere and magnetosphere are performed on the
basis of the European Incoherent Scatter Radar (EISCAT) and Super Dual
Auroral Radar Network (SuperDARN) measurements combined with optical
observations of auroras, as well as with satellite observations in the
region of dayside auroral oval, where the solar wind / magnetosphere
interaction is manifested. Two main problems are investigated: (1) The
field-aligned currents, magnetospheric plasma domains and generation
mechanisms of dayside auroras; (2) Structure and dynamics of the dayside
magnetosphere and signatures of the magnetospheric domains in the radar
(EISCAT and SuperDARN) dat
