Title: Io's Atmosphere: Density above Volcanoes

Abstract: We are requesting TEXES time to execute two different types of observations in order to determine the nature of Io's atmospheric support and the relative importance of volcanic support on the overall atmospheric density. We will observe the SO2 absorption spectrum at 8.6 Ám to obtain information on the latitudinal distribution of the atmospheric density directly above volcanoes on the anti-Jupiter hemisphere. We will also observe Io's atmosphere as it enters Jupiter eclipse at 18.9 Ám. This will investigate if the atmosphere is concentrated over the volcanoes on the Jupiter-facing hemisphere or if the atmosphere is predominately sublimation driven. This will be the first time the bulk atmosphere will be sampled in eclipse.
