Abstract
THE wave-form of an atmospheric, resulting from a distant lightning flash to Earth, has variously been interpreted in terms of pulse reflexion between parallel or concentric conducting Earth and ionospheric layers1,2 or as pulse dispersion during propagation in the region between these same layers3. Recent papers4,5 have discussed the equivalence of these approaches. In each case the Earth–ionosphere separation and the storm distance are the principal determinants of the positions of the peaks of the trace. Within certain limits these propagation parameters may be estimated from the observed waveforms.
