Hi Nick-
We currently support trajectories with a vertical dimension of
Altitude, but it looks like yours is pressure. Do you have
an Altitude variable in your file?
You also need to select the Data Source Type in the chooser
as a Track File instead of using the default (I'm Feeling Lucky).
For .nc files, the default tries to open it as a grid.

Hello. Can someone update me on the state of trajectory support in IDV?
I'm trying to load the following netcdf but complains it isn't
recognised as a grid (ok granted it has uppercase Latitude/Longitude,
and no :cdm_datatype as UODC suggests, but then neither does your sample
either at
