文摘
- •
Model of electron energy distribution function and its spatial structure in Callisto’s ionosphere.
- •
Model simultaneously explains electron column density measurements by the Galileo spacecraft and observations of UV emission by the Hubble Space Telescope.
- •
Model implies average atmospheric O2 column density of 2.1 × 1019 m−2 with a day night asymmetry.
