Modeling results of volcanic plumes on Jupiter's moon lo are presented. Two types of low density axisymmetric SO2 plume flows are modeled using the direct simulation Monte Carlo method. Thermal radiation from all three vibrational bands and overall rotational bands of SO2 molecules are included in the simulations. The radiation features were examined both by calculating infrared emission spectra along several lines-of-sight through the plume and the DSMC modeled emission images of the whole flow field. A high resolution plume core flow was obtained by multi-domain sequential calculation to better study the radiation signature. The simulation results are compared to the existing observation data. Future comparisons with the Galileo or other astronomical observations are expected to validate and improve our model.
