Abstract:

The old problem of electromagnetic transients from exoatmospheric photon bursts has been restudied, by considering the photons to be generated from a spectrally finite source and not a monoenergetic source, as is usually done. Variables in the electromagnetic field equations are obtained by spectral averaging. Stratification of target molecules in the atmosphere leads to stratification of radiation sources. A conducting layer in the lowest strata develops due to high-energy electrons, leading to a reduction in field intensities near the ground.
