[netcdf-java] Storm tracks as trajectories

I'm working on writing tropical storm track data in netCDF.
I think they should be written as CDM trajectories, but am unsure how to have ToolsUI recognize them as trajectories. I've attached below the CDL for a simple set of two storms. What do I need to change to have ToolsUI recognize them as trajectories??

Thanks in advance-
