Jim, Good timing. As of IDV 5u1 which will be release this week, the IDV can now handle multiple trajectories in one CF-compliant file. When wanting to view these data, select a Data Source Type of "Trajectory Sounding Files". You will have to build the trajectory file in a CF compliant manner as described here: http://www.unidata.ucar.edu/blogs/developer/en/entry/ipynb_cookbooks_to_create_cf. This new IDV functionality should still be considered beta quality and there could very well still be problems. Please keep us up-to-date on your progress.
