abstract = "The plasma-satellite electrodynamic interactions that occur inside
the Jovian magnetosphere with the Galilean satellites produce
field-aligned electric currents that are carried by Alfv{\'e}n
waves towards Jupiters ionosphere, accelerating electrons and
causing auroral emissions at UV, IR and radio wavelengths. The
Jovian Decametric (DAM) radio emissions are produced by
electron-wave resonance through the Cyclotron Maser Instability
(CMI) at the local electron cyclotron frequency. These emissions
have frequencies from a few MHz to \∼40 MHz, and,
therefore, are partially observed from the Earth >10 MHz. The
long-term monitoring of Jupiter by the Nan{\c{c}}ay Decametric
Array has enabled to collect more than 40 years of daily
observations of Jupiter between 10 and 40 MHz. The last 30 years
of observations (since 1990) compose the NDAs extensive digital
catalog, which based the in depth study of the various Jovian DAM
components, and provided evidences of emissions driven by Io,
Europa and Ganymede. However, radio observations from ground-based
instruments such as the NDA are limited by the terrestrial
ionospheres cutoff frequency, of \∼10 MHz, and by Radio
Frequency Interference (RFI) up to \∼20 MHz. In this
context, the complementary use of observations from
spacecraft-based radio instruments emerges as an interesting
possibility to improve the analysis of planetary radio emissions
by overcoming the frequency limitation of terrestrial
observations. Wind is a spacecraft that has been on space, at the
vicinity of the Earth, since the end of 1994, collecting radio DAM
emissions with frequencies up to 14 MHz through the onboard WAVES
experiment, whose frequency range coverage comprises part of the
Jovian DAM emission that is not detectable by the NDA. Jupiter is
observed by Wind in some parts of the spacecrafts orbit, making it
possible for WAVES receivers to occasionally detect Jovian DAM
emissions at low frequencies. Therefore, this work aims at
producing a catalog of Jovian DAM emissions observed by both the
NDA and Wind to improve the analysis of the emissions controlled
by the Galilean satellites that have been observed on the NDAs
catalog, by extending these emissions to their lower frequencies
observed by Wind. This extension enables the visualization of the
entire frequency range of the emissions and a more complete
analysis of their arc shapes formed in the dynamic spectra.",
