Abstract :
Electromagnetic emissions observed in the nearest Earth environment are a superposition of natural emissions and various types of man-made noises. Also, as a consequence of catastrophic events on the Earth surface such as: thunderstorm activity, earthquakes, volcanic eruptions, electromagnetic signals are registered on board low orbiting satellites. Therefore, a more accurate physical description of such a complex and dynamic system calls for a long term multi-point and multi-scales coordinated monitoring of space environment. The magnetised solar-terrestrial space plasma is a highly non-linear medium, which exhibits many different types of turbulence and instabilities. A study of mass, energy, and momentum transport in the solar terrestrial plasma is directly related to the study of space plasma turbulence. The wide range wave in situ diagnostics and new generation multi-point and multi-type sensor diagnostics, as the LOFAR-LOIS system can be a good tool for monitoring such complex system. Ground-based multi-frequency and multi-polarisation netted radio and radar facilities and observation clusters in space will be helpful to find solutions to problems in space physics and to detect long-term environmental changes. The presentation will give the overview of physical problems relates to diagnostics the plasma turbulence in near Earth environment and will present the new observation techniques devoted to the space plasma diagnostics; as in situ wave measurements combined with ground based LOIS netted radar registration.
