             abstract = "The Jovian Decametric (DAM) radio emissions are anisotropically 
                         beamed emissions generated via cyclotron maser instability at 
                         Jupiters auroral regions. It is long known that the observation of 
                         these emission is affected by the variation of the observers 
                         latitude (or declination - DE) in the Jovian System III, but the 
                         declination effect is still not well understood. In this work, we 
                         analyze Jovian DAM emission detected by the Nan{\c{c}}ay 
                         Decameter Array from 1990 to 2020 and suggest a selection of the 
                         emission by intensity and maximum frequency thresholds to remove 
                         the superimposed effects of the variation of observer-Jupiter 
                         distance and of Jupiters elongation angle. Then, we study the pure 
                         effect of DE on the selected emissions duration, maximum 
                         frequency, average longitude (CML) and average Io phase. The same 
                         analysis is applied on simulations of Jovian emission by the 
                         Exoplanetary and Planetary Radio Emissions Simulator (ExPRES). 
                         ExPRES seems to predict the emission and their variation with DE 
                         consistently with what is observed in the NDA data, and might be 
                         an additional tool to confirm the theory on the emissions origin 
                         and to improve our understanding of the DE effect on the emission 
                         observation.",
