Solar System Low Frequency Radio Spectra

Monday 13 February 2023, by Baptiste Cecconi

This dataset contains the natural solar system low frequency radio emission spectra for the Sun, the Earth, Jupiter, Saturn, Uranus and Neptune. This dataset has been used to produce the figures of Zarka et al. PSS (2012).

Link to data


The dataset contains the spectral flux density distribution of low frequency planetary radio emission components;

  • the Jovian magnetospheric radio emissions (with average and peak levels):
    • Quasi Periodic Bursts (QP),
    • Narrow-band Kilometric (nKOM),
    • Broad-band Kilometric (bKOM),
    • Hectometric (HOM),
    • Decametric (DAM),
    • Io-controlled Decametric (Io-DAM);
  • the Jovian radiation belt spectrum (DIM - decimetric).
  • the terrestrial Auroral Kilometric Radiation (AKR) from dayside and nightside;
  • the Saturn Kilometric Radiation (SKR) and Saturn Electrostatic Discharges (SED);
  • the Uranus Kilometric Radiation (UKR) and Uranus Electrostatic Discharges (UED);
  • the smooth Neptune Kilometric Radiation (NKR) and Neptune kilometric burst emission (NepB);
  • the Solar average and peak emission spectrum (Solar type III bursts);
  • the quiet and disturbed Sun spectra.
