Dataset: Radio Frequency Characteristics of Volcanic Lightning

This data set contains broadband VHF waveforms of vent discharges and volcanic lightning flashes collected during an explosive eruption of Sakurajima volcano in Japan on November 8, 2019. Each file in the dataset is a 3 microsecond waveform. The amplitude values of the waveform are in arbitrary voltage units. The sampling rate is 180 MS/s. There are two tar archive files included in this data set: one for all of the vent discharge waveforms and one for all of the flash waveforms. The UTC time of the waveform, corresponding to the time of the peak of the waveform is included in each file name in the tar archives. The UTC time is given as seconds of the day on November 8, 2020.
