The Juno spacecraft arrived at Jupiter July 4, 2016 and is now in a 53.5-day polar orbit. Synchrotron radiation generated by ultra-relativistic electrons trapped in Jupiter's magnetosphere is detected and measured by the MWR Radiometer over a range of wavelengths from 2 cm to 50 cm. An extension of the Levin et al. (2001)multi-zonal, multi-parameter model to simulate synchrotron emission using assumed electron distributions and Jovian magnetic field models (VIP4 and the latest incarnation, JRM09)generates the four Stokes parameters of the synchrotron emission. The model depends on magnetic-field-derived quantities such as L-shell and B critical, the minimum magnetic field amplitude for a given L-shell at which electrons that mirror at or below the upper boundary of the atmosphere are lost. This study describes the modeling issues associated with aforementioned derived parameters and results for VIP4 and JRM09 models.
