      <Description>This dataset contains the electric field power spectral density of natural waves observed by WHISPER.
Compared to the WHI_NATURAL and WHI_ACTIVE datasets, the particularity of this dataset is that bandwidth of the measurements is large, so as to optimise the time resolution.
The dataset includes data obtained both when the sounder is active and passive (natural waves).

The support data includes : 
    a flag to indicate sounder activity 
    the number of elementary spectra which have been summed. Individual spectral are acquired every 13.33 ms, and these spectra are averaged to improve the statistics.
    an indicator of how many, if any, of the individual spectra were saturated.</Description>
