Scope:

In this symposium, SSRE (Center for Space Science and Radio Engineering) in UEC invites scientists to present all aspects of experimental and theoretical results in relation with measurement of natural and man-made electromagnetic signals. Scientific results to be useful to monitor and predict the Earth's environment as well as to mitigate different types of natural disasters are also welcome. This is a small but a unique and exciting workshop to exchange ideas and to stimulate new insights to understand the interdisciplinary topics by experts from different research fields.

Examples of scientific topics are:

-Space weather and solar terrestrial environment
-Atmospheric electricity (lightning physics and related electromagnetic phenomena)
-Climate change, hazardous weather and thunderstorm activity
-Lightning damage and protection
-Ionosphere
-Radio Astronomy
-Electromagnetic compatibility
-Space communications
-Radio Sensing technique
