A new magnetic field model for Jupiter, based on Juno’s first nine orbits observations,JRM09, was recently proposed by Connerney et al. [Geophys. Res. Lett., 45, 2590-2596,2018]. We use this model to investigate the angular distribution of the Jovian decameterradiation occurrence probability, relatively to the local magnetic field B and its gradient ∇Bin the source region, and we compare the results to those obtained several years ago usingolder models (O6, VIP4, VIT4 and VIPAL). The JRM09 model confirms the former results:the radio emission is beamed in a hollow cone presenting a flattening in a specific direction.The same assumptions were made as in the previous studies: the Jovian decameter radiationis supposed to be produced by the cyclotron maser instability (CMI) in a plasma whereB and ∇B are not parallel. As a consequence, the emission cone does not haveany axial symmetry and then presents a flattening in a privileged direction. Thisflattening appears to be more important for the northern emission (34.8%) than forthe southern emission (12.5%) probably due to the fact that the angle between thedirections of B and ∇B is greater in the North (∼ 10∘) than in the South (∼ 4∘).
