1 ELECTROMAGNETIC EARTH ENVIRONMENT
Electromagnetic emissions observed in the nearest Earth environment are a superposition of natural emissions and various types of man-made noise. Also, as a consequence of catastrophic events on the Earth's surface such as thunderstorm activity, earthquakes, and volcanic eruptions, electromagnetic signals are observed on board low orbiting satellites. Therefore, a more accurate physical description of such a complex and dynamic system calls for a coordinated long-term, multi-point and multi-scale monitoring of the space environment. The magnetised solar-terrestrial space plasma is a highly non-linear medium exhibiting 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. A wide range of in situ diagnostics and new generation multi-point and multi-type sensor diagnostics, such as the LOFAR and LOIS systems, can be excellent tools for monitoring this complex system. In the presentation, I will give an overview of physical problems related to the diagnostic of plasma turbulence in near Earth environment and will point out the scientific challenges of the described new advanced combined techniques for in situ and netted ground based diagnostics.

3 Wave in situ diagnostics
ULF and LF ion plasma diagnostics, E B field fluctuations. VLF low density plasma diagnostics HF electron plasma diagnostics, Solar radio burst. Wave in situ diagnostics Local plasma frequency =local electron density tens kHz up to few MHz Local gyro-frequency proportional to the intensity of magnetic field tens kHz up to MHz The ionosphere represents less than 0.1% of the total mass of the Earth's atmosphere. Even so, it is extremely important!
