Presentation on theme: "ELECTROMAGNETIC EARTH ENVIRONMENT"— Presentation transcript:
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.Hanna RothkaehlSpace Research CenterPolish Academy of Sciences, PolandCOSTMP Warszawa

Even so, it is extremely important!
