Abstract
We offer a model which explains the observations of sodium D-line emission from lo. Our model involves: (1) chargedparticle sputtering of sodium from Io's surface, (2) ejection of sodium into a cloud surrounding lo and (3) resonant scattering of incident sunlight. Observational consequences and tests of the proposed model are also discussed. Subject headings: atmospheres, planetary - Jupiter - line formation - satellites
