Dear VAPOR staff,
I have been trying to create a .vdf with "-gridtype layered" from my ARPS NetCDF data (uniform grid in X and Y, but stretched in the vertical; flat surface) using either:
ncdfvdfcreate -timedims Time -vars3d QC -dim 842x562x82 arps.net018000 -gridtype layered test.vdf
or
vdfcreate -timedims Time -vars3d QC -dim 842x562x82 arps.net018000 -gridtype layered test.vdf
In the former case, I get the error: "Invalid variable "NONE" " and in the latter no vdf files are created (no error message, but the -help options are displayed).
Using the 2nd command removing the option "-gridtype layered" creates a .vdf file, but the cloud does not look reasonable (e.g., the cloud base appears erroneously too high) so that I believe I'm misusing the commands. I have tried other options (e.g., "stretched") Could you help solve this issue?
Below is part of the output of 'ncdump -c' command:

Thank you very much in advance!
