Brief summary

• Met.3D is able to visualize 3D trajectory data as "3D tubes" and "3D particles" coloured by pressure elevation or by any other auxiliary/traced variable.
  • See Trajectory actor
• Pre-computer trajectories can be loaded from NetCDF files.
• Met.3D can also compute trajectories and streamlines on-the-fly, using trajectory computation equivalent to that of the LAGRANTO model (cf. https://doi.org/10.5194/gmd-8-2569-2015).
• Trajectories can be filtered according to "ascent per time interval" to capture Warm Conveyor Belt features (see https://doi.org/10.5194/gmd-8-2355-2015).
• Please let us know if this functionality is useful for you and you would require further development.
