Caveats The WHISPER sounders operate on a duty cycle, so the electron density is sampled on neither a continuous nor a constant basis. This duty cycle covers situations from continuous active modes with one sounding occurring typically every 1-3 seconds, to natural mode operation only when no sounding is performed, and hence no density is provided for long periods. When many density values are available during a PPDB/SPDB interval, the averaged value is provided. When no value is available during such a time interval, the fill value (no data) is given. For example, in the typical WEC normal mode, a double sounding occurs over 3 s every 52 s. Thus, for PPDB, a density value, averaged over 2 spectra, is available followed by 6 fill values. For the SPDB, 2 averaged values are available 52 s apart. They are averaged for the SPDB slot. spase://CNES/Person/CDPP-Archive/Pierrette.Decreau PrincipalInvestigator spase://CNES/Person/CDPP-Archive/Patrick.Canu CoInvestigator spase://CNES/Repository/CDPP-Archive/REGARDS-CDPP Online REGARDS https://regards.cnes.fr/user/cdpp/modules/1777?sp=DatasetName;q=DatasetName:CLU_SP_CL_WHI Access via CNES Data Archive for CDPP CDF Calibrated spase://CNES/Instrument/CDPP-Archive/Cluster-1/WHISPER spase://CNES/Instrument/CDPP-Archive/Cluster-2/WHISPER spase://CNES/Instrument/CDPP-Archive/Cluster-3/WHISPER spase://CNES/Instrument/CDPP-Archive/Cluster-4/WHISPER ElectricField Waves.Passive Waves.Active 2001-01-09T00:00:00Z 2012-12-31T00:00:00Z Earth.Magnetosheath Earth.Magnetosphere Earth.Magnetosphere.Magnetotail Earth.Magnetosphere.Main Earth.Magnetosphere.Polar Earth.Magnetosphere.RadiationBelt Earth.NearSurface.AuroralRegion Earth.NearSurface.Ionosphere Earth.NearSurface.Plasmasphere Earth.NearSurface.PolarCap Heliosphere.NearEarth Electron Number Density Cluster Summary Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electron number density derived from plasma frequency recognition at spin time resolution cm^-3 1e6>m^-3 Electron Scalar NumberDensity Cluster WHISPER Summary Param Electron Number Density Quality Resonance Identification Flag Cluster Summary Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electron number density quality of the resonance recognition flag at spin time resolution Other Cluster WHISPER Summary Param Electric Field spectral density (4–80 kHz) Cluster Summary Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electric field spectral density in the 4-80 kHz frequency range at spin time resolution V^2 m^-2 Hz^-1 Scalar Electric 4000 80000 Hz Cluster WHISPER Summary Param status Cluster Summary Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation status at spin time resolution Other
