Abstract:
Using 25 inbound passes through the Jovian system, we combine measurements from the fields and particles instruments on the Juno spacecraft to survey the properties of Jupiter’s plasma disk. Juno’s orbit is particularly useful for exploring the variation in plasma conditions with latitude as well as radial distance (from ~10 to ~50 RJ). We present basic plasma properties (composition, density, temperature, velocity, magnetic field strength) as well as derived quantities (pressure, plasma beta, gyroradius, Alfvén speed) and incorporate the JRM09+CAN field model into maps of the plasma environment.
