Each plot spans one day. These data were obtained from the Ev long wire antenna in the spin plane and the Eu two-sphere antenna via the SFR receiver. The title above each spectrogram is "ISEE-1 PWI Sweep Frequency Receiver Ev and Eu Antennas" Each spectrogram is a plot of the power spectral density of received signal (color scale) as a function of operating frequency (in a logarithmic scale on the vertical axis) and time (horizontal axis). Beneath the time labels on the horizontal axis of the spectrograms are ephemeris data: position of the spacecraft in radial distance (Earth radii), geomagnetic latitude, magnetic local time, and McIlwain L-shell. Overlaid on each image are traces of the electron cyclotron frequencies. Located in the same directory are are the 12 hour ISEE-1 PWI Spectrum Analyzer (SA) spectrograms. spase://SMWG/Person/Donald.A.Gurnett PrincipalInvestigator spase://SMWG/Person/Jolene.S.Pickett MetadataContact spase://SMWG/Person/Larry.J.Granroth MetadataContact spase://SMWG/Person/Chris.W.Piker MetadataContact The University of Iowa ISEE-1 PWI Page http://www-pw.physics.uiowa.edu/isee/ en spase://NASA/NumericalData/ISEE1/PWE/SFR/PT32S DerivedFrom spase://VWO/DisplayData/ISEE1/PWE/SFR.P1D spase://VSPO/DisplayData/ISEE1/PWE/SFR/P1D spase://SMWG/Repository/NASA/GSFC/SPDF Online Open HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/pre_generated_plots/isee/isee1/ Access to a directory tree (ordered by year) of PNG format plots for ISEE-1 SFR (daily) and SA (12 hour) dynamic spectrograms. en PNG None spase://SMWG/Repository/UIowa/RadioPlasmaWaveGroup Online Open HTTPS from SPDF http://www-pw.physics.uiowa.edu/plasma-wave/isee/data/ISEE1/cdf/browse/ Access to a directory tree (ordered by the year/month/day) of PNG format plots for ISEE-1 SFR (daily) and SA (12 hour) dynamic spectrograms. en PNG None spase://SMWG/Instrument/ISEE1/PWE Waves.Passive 1977-10-26T00:00:00Z 1987-09-26T23:59:59Z P1D Earth.Magnetosphere Earth.NearSurface.Plasmasphere Earth.NearSurface.AuroralRegion Earth.NearSurface.PolarCap Heliosphere.Inner Dynamic Spectrogram Spectrogram AKR Auroral hiss Auroral Kilometric Radiation Banded emissions Broadband Electrostatic Noise (BEN) Chorus Continuum radiation Electron Acoustic Waves Electron Foreshock Waves Electromagnetic Ion Cyclotron waves EMIC Electron Cyclotron Harmonics Equatorial Noise Ion Acoustic Waves Ion Foreshock Waves Kilometric Continuum radiation Lion Roard Myriametric radiation Plasmaspheric Hiss Solar radio burst Terrestrial Kilometric Radiation TKR UHR Upper hybrid resonance Whistler mode Whistlers Electric Power Spectral Density V^2*m^-2*Hz^-1 PlasmaWaves Magnitude Pseudo ACElectricField RadioFrequency 104 400000 Hz
