  A new empirical, analytical model of cold plasma (< 10 keV) in the Jovian
inner magnetosphere is constructed. Plasmas in this energy range impact surface
charging. A new feature of this model is predicting each plasma parameter for a
specified probability (percentile). The new model was produced as follows. We
start from a reference model for each plasma parameter, which was scaled to fit
the data of Galileo plasma spectrometer. The scaled model was then represented
as a function of radial distance, magnetic local time, and magnetic latitude,
presumably describing the mean states. Then, the deviation of the observed
values from the model were attribute to the variability in the environment,
which was accounted for by the percentile at a given location.The input
parameters for this model are the spacecraft position and the percentile. The
model is inteded to be used for the JUICE mission analysis.
