MODIFICATION OF PLANETARY
ATMOSPHERES BY MATERIAL
FROM THE RINGS

ABSTRACT
The atmospheres and ionospheres of ringed planets can be, and perhaps are, modified by the
injection of gaseous neutral and ionized species, and dust of ring origin. Although no
direct evidence for such interaction exists, many of the unresolved characteristics of
planetary ccn,position, thermal structure and ionosphere would be understood if the rings
supplied certain materials to their parent planets.
INTRODUCTION
The definition of `rings' in this paper has been stretched somewhat to include the
`toroidal gas/plasma ring' in the orbit of Ia around Jupiter. Otherwise, the extensive
ring system of Saturn, diffuse ring of Jupiter, and the recently discovered rings of
Uranus are the focus of bulk of the discussion. Neptune too may possess rings, and their
influence is considered as part of a general theme on the tropospheric/stratospheric
