JOSE: A New Jovian Specification Environment Model

This document presents a new Jovian Specification Environment model (JOSE), developed at ONERA based on Galileo data and validated with all relevant data measured by spacecraft having flown by or orbited Jupiter, in order to obtain an easy-to-use engineering model for Jupiter's environment. This model has been developed for protons and electrons from several tens of keV to several hundreds of MeV.
