Solution of lightning intensity distance distribution reconstruction problem by using the Schumann resonance signal

The inverse problem solution for revealing total worldwide lightning intensity and its distance distribution based on decomposition of average background Schumann resonance (SR) spectra is considered. The developed one-site technique can be applied without invoking any preliminary knowledge about spatial structure of the world thunderstorm activity. The technique allows a reduction of the influence of additive interference occurring in experimental measurements. Apart from average electric and magnetic field power spectra for the inverse problem solution it is suggested to use their linear combinations emphasizing the distance dependence and basic SR peaks. The influence of errors in source spectra and propagation parameters on recovered lightning intensity and its distance profile has been studied numerically.
