[IDV #GAI-830760]: Is there a 'turnkey' application that displays trajectory plots?


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:

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.
