The Io sulfur torus in 1981Io torus spectrometry obtained in the S II and S III forbidden lines during February-March 1981 indicate that these emissions are correlated in the warm torus, and possess similar scale heights along the magnetic field lines. The observed emission scale heights can be used to estimate the ion temperature parallel to the magnetic field, given the effective ion mass. Attention is also given to simultaneous measurements of the S II forbidden 6731 line profile obtained on one night with a Fabry-Perot scanning spectrophotometer.
