Data format for the flow renderer

Hello,
I am trying to convert a trajectory output data into the netcdf form for VAPOR.
I am confused about what format I should convert it into. The flow renderer asks for X, Y, Z variables, which makes sense. But the trajectory data (XYZ variables) has coordinate variables such as parcel IDs and time. This does not seem to be compliant with the CF conventions.
Is there any sample netcdf data for the flow renderer?

Thank you!

Hello Xunwang,

I’m not sure what you want to achieve. Here are a few things to notice, and maybe you could elaborate what you’re trying to do.

  1. VAPOR does not support trajectories in CF conventions.
  2. Flow renderer accepts imported data the same as all other renderers.
  3. Flow renderer uses seed positions and a velocity field to calculate and render flow lines.
  4. There is currently no machenism for the flow renderer to read in trajectories output by others and simply render it.

Best,
Sam
