Abstract

In this paper A portable detection system for Schumann resonances (SR) measurements is presented. SR are ELF natural electromagnetic eigenmodes in Earth-ionosphere cavity. These electromagnetic waves have been suggested to monitor climate, electrical activity in the atmosphere and other earth — atmosphere phenomena providing observations of great importance. In the present work, we studied the antenna structure and the electronic set-up to achieve high sensitivity and long term monitoring of SR magnetic field components. The corresponding calculated and measured results focus on the whole system performance enhancement. A series of measurements taken in a spot at the prefecture of Ioannina Greece, indicate that our measurement set-up can reliably measure up to 6 harmonics in SR spectrum, efficiently.
