Ok. We will fix the time dimension. We do have working netCDF that include a
non-spatio-temporal dimension (layer) but it is ordered after the spatial
dimensions and time is in the right format. This is a stochastic model and
realn is just the realization. It is surprizing to me if CF world doesn’t
handle it.

Hi Phil,
The WMS part of THREDDS expects all the dimensions of a variable to be spatial
or temporal. Your datasets have a "realisation" dimension, which is not
recognised and therefore unfortunately the WMS can't handle the variable.
Also, your first dataset has a time dimension that is not described in a
CF-compliant way (the units should be something like "days since X"), so that
dimension would probably not be recognised as a valid temporal axis.
Hope this helps,
Jon

Whoops, the second netcdf file isnt working either.

We have a 5D netCDF which works fine in Panoply, but when we try to use it
in thredds, we don?t get a list of variable. Digging deeper, I see that call to
/thredds/wms/gwAll/hpm_outputs.nc?item=menu&menu=&request=GetMetadata returns:
{"label":"GNS Thredds","children":[{"label":"hpm model
outputs","children":[]}]} I don?t see any errors reports in the
threddsServlet.log.
A very similar file in the same datascan but with one less dimension is
working ok.
