Flux-Density Maps of Jupiter's Decametric Radio Sources

Nine years of observations of Jupiter's decametric radio emissions are summarized in maps showing average peak flux density as a function of central meridian longitude and the orbital position of lo. It is shown that a simple scale conversion allows the maps to be interpreted as maps of long-term mean flux density. The empirical probability and flux maps are compared with the predictions of recent theoretical models proposed by McCullocb and by Sc batten and Ness.
