Perytons are terrestrial signals that exhibit dispersion measure (DM) similar to pulsars. In trying to identify terrestrial sources of such perytons, investigation into signals from airborne equipment (aircraft), RFI emissions from electronics and lightning phenomenon reveals that the possible sources of perytons could be lightning phenomenon. Narrow Bipolar Pulses (NBPs) and Terrestrial Gamma Flashes (TGFs) are good investigational candidates.
