23Schumann resonances — The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, excited by lightning discharges in the …
24Distributed temperature sensing — systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high… …
