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_PP_C3_WHI Access via CNES Data Archive for CDPP CDF Calibrated spase://CNES/Instrument/CDPP-Archive/Cluster-3/WHISPER ElectricField ThermalPlasma Waves.Passive 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 3 Prime 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 3 WHISPER Electron Number Density Quality Resonance Identification Flag Cluster 3 Prime 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 3 WHISPER Electric Field Spectral Density (4-10 kHz) Cluster 3 Prime Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electric field spectral density in the 4-10 kHz (f4) frequency range at spin time resolution V^2 m^-2 Hz^-1 Scalar Electric 4000 10000 Hz Cluster 3 WHISPER Electric Field Spectral Density (10-20 kHz) Cluster 3 Prime Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electric field spectral density in the 10-20 kHz (f5) frequency range at spin time resolution V^2 m^-2 Hz^-1 Scalar Electric 10000 20000 Hz Cluster 3 WHISPER Electric Field Spectral Density (20-80 kHz) Cluster 3 Prime Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation electric field spectral density in the 20-80 kHz (f6) frequency range at spin time resolution V^2 m^-2 Hz^-1 Scalar Electric 20000 80000 Hz Cluster 3 WHISPER Normalized Electric Field Variance Cluster 3 Prime Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation normalized electric field variance at spin time resolution Scalar Electric Cluster 3 WHISPER STAFF status Cluster 3 Prime Parameter Waves of HF and Sounder for Probing Electron Density by Relaxation status at spin time resolution Other
