Abstract Millimeter-wave observations of SO 2 have allowed the first groundbased direct detection of Io's neutral atmosphere. From observations of two SO 2 rotational lines, at 221.965 and 143.057 GHz, tentative detection of a third SO 2 line, at 346.652 GHz, and upper limits on two other lines, basic properties of Io's atmosphere are inferred. The SO 2 atmosphere appears to have global temporal stability and can be represented by a collisionally thick 10 11 −10 12 cm −3 atmosphere ( p = 3−40… CONTINUE READING
