Residual Study: Testing Jupiter Atmosphere Models Against Juno MWR Observations [PDF]

open access: goldEarth and Space Science, 2020
The Juno spacecraft provides unique close‐up views of Jupiter underneath the synchrotron radiation belts while circling Jupiter in its 53‐day orbits. The microwave radiometer (MWR) onboard measures Jupiter thermal radiation at wavelengths between 1.37 ...

Periodic modulation of gas giant magnetospheres by the neutral upper atmosphere [PDF]

open access: yesAnnales Geophysicae, 2006
Periodic signatures present in the magnetospheres of both Jupiter and Saturn have yet to be fully explained. At Jupiter the unexplained signatures are related to emissions from the Io torus ("System IV"); at Saturn they are observed in emissions of ...
