We show images of propagation spectrograms based on spacecraft observations of electromagnetic radiation of lightning strokes. We use multicomponent data of the DEMETER spacecraft, and we match observations of fractional-hop whistler signals with the source lightning strokes in the Mediterranean region. We perform multidimensional analysis of the spacecraft data, and we obtain detailed information on wave polarization characteristics and propagation directions.
