Caudal (1986) presented an elegant Euler potential model of the jovian magnetodisc where the magnetospheric mechanical and magnetic stresses were balanced. The modelling methodology results in a magnetic structure that is in stress balance with the energetic particle and plasma properties in the magnetosphere. These plasma properties are introduced into the model via a set of boundary and input conditions. Recently, Achilleos et al. (submitted manuscript) have implemented this model for both Jupiter and Saturn and have used this model to investigate magnetospheric stress balance at Saturn using Cassini-era plasma data. In this paper, the Achilleos et al. implementation of Caudal's model is used to build a new model stress balanced model for the jovian magnetodisc using up-to-date plasma parameters from Voyager, Ulysses and Galileo. The calculated magnetic field profile and plasma sheet structure will be compared with observations and previous models. As part of ongoing work we will investigate and discuss local time effects, dayside magnetodisc disruption, and magnetodisc stress balance in the jovian magnetosphere.
