The key parameter spectrograms are calibrated plots from the LFR, MFR, and HFR. Each presents a full day in time and a frequency range from 2 Hz to 16 MHz. The data set is described in CATALOG/KEYDS.CAT.
Each link in the following list presents a thumbnail index with a maximum 100-day interval based on the first digit of the three-digit day of year.
The low rate spectrograms are calibrated plots from the LFR, MFR, and HFR. Each presents a full day in time and a frequency range from 2 Hz to 16 MHz. The data set is described in CATALOG/LRFULLDS.CAT.
Each link in the following list presents a thumbnail index with a maximum 100-day interval based on the first digit of the three-digit day of year.
The wideband spectrograms are a set of calibrated plots of the Fourier transformed waveform captured in either of two frequency ranges: 10kHz or 75kHz. Each presents up to an hour in time. The data set is described in CATALOG/WBFULLDS.CAT.
Each link below presents a list of individual days in a maximum 100-day interval which link to thumbnail indexes of hourly spectrograms.
The waveform spectrograms are a set of calibrated plots of the Fourier transformed waveform captured in either of two frequency ranges: 25Hz or 2.5kHz. Each presents up to a day in time. The data set is described in CATALOG/WFFULLDS.CAT.
Each link in the following list presents a thumbnail index with a maximum 100-day interval based on the first digit of the three-digit day of year.
