7 years ago It accepts mpas files with model_name or Conventions set to mpas. It now also accepts data files with the mesh_spec attribute set. Please let me know if there are any valid MPAS files that aren't recognized or if you see any false positives.

It also has a bogus hard-coded list of vertical dimensions. In particular, it does NOT support normal chemical-emissions files.
For an example of how it SHOULD have been done, see:

VERDI does NOT even recognize variable "zgrid" from a normal MPAS-met "history" file. That failure to recognize it is COMPLETELY BOGUS.

7 years ago zgrid is used to retrieve the elevation that's displayed in the bottom corner when you move the mouse over the map. Would it be helpful to plot it directly in the map? That shouldn't be too hard to add.
And yes, we know about the lack of chemical emissions support. That's one of the enhancements we'd like to add.

Yes -- I've been dealing with a problem of "what layer is that airplane flying in", and trying to get that info by looking at values "by hand" in a debugger is quite tedious.
And it's easy to imagine formulas that involve "zgrid" -- lapse-rates for example.
Generally. VERDI should plot any variable with subscripting of the forms A[nCells] B[Time][nCells] C[nCells][something] D[Time][nCells][something]
where if the "something" is unrecognized, it should still be treated as a layer-dimension, using uniform layers for vertical cross sections if necessary. Arguably (for those doing advection research), you should be able to replace the "nCells" dimension by "nEdges" or "nVertices" and plot edge-based or vertex-based variables.

The file-spec for MPAS can be found at: https://mpas-dev.github.io/files/documents/MPAS-MeshSpec.pdf "model_name" is NOT one of the listed required attributes, but MPASConvention.java seems to require it. As the sole requirement!
