             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.",
