[Paraview] netcdf-4

[David E DeMarle]

In a fresh build of paraview master on a mac, I can read this file without
a problem. When I go to open the file I'm given a choice of "CAM NetCDF
(Unstructured)" or "NetCDF files generic and CF conventions". Choose netcdf
cf and, accept defaults and hit apply and I see the data, curvilinear with
72/91 cells and points and two cell aligned float arrays, pressure and
temperature.

It is possible to turn OFF support for netcdf4 if VTK_USE_SYSTEM_HDF5 on
and HDF5_HL is off that will happen. I am guessing that is what is going on
here in ubuntu's ParaView package.

You can:
 try a nightly build from the kitware download site
 ask the ubuntu packager to turn it on in the future
 build paraview yourself from source
