Okay, thanks for the info Daniele,
I do have the content as a list of hourly pngs, perhaps I can
geo-reference them then add them as an ImageMosaic.

Hi Matt,
I have checked the second NetCDF file you provided.
Although this one will be properly opened by the UCAR lib (note: this
is the low-level one), GeoServer and GeoTools won't be available to
open that (these high level libs can only deal with CF datasets), due
to the lack of proper dimensions and properly specified Coordinates.
See these sections of the convention for further details:
http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#grid-mappings-and-projections
http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#appendix-grid-mappings
As well as the main GeoServer NetCDF documentation pages.
http://docs.geoserver.org/latest/en/user/extensions/netcdf/netcdf.html#notes-on-supported-netcdfs
http://docs.geoserver.org/latest/en/user/extensions/netcdf/netcdf.html#supporting-custom-netcdf-coordinate-reference-systems
Hope this helps.
Cheers,
Daniele

Hello Daniele,
Thanks for the reply, not an expert on this but I will answer to
the best of my abilities.
The netCDF files are an output of a fire smoke dispersion model
called bluesky <http://www.airfire.org/bluesky/> in which are
initialized by .ARL files from National Weather Service containing
met info of our domain.
The .ARL file's coordinate system is Polar stereographic
projection which seems to be related to the M3IO convention. As
well, the M3IO api
<https://www.unidata.ucar.edu/software/thredds/v4.3/netcdf-java/v4.2/javadoc/ucar/nc2/dataset/conv/M3IOConvention.html>mentions
this convention is a standard for air quality models (EPA),
perhaps this is related to the dispersion model I am using.
As well, in a vain attempt to make the netCDF convention fit into
COARDS, the .nc file named 'dispersion2' has it's dimension names
editted. Dispersion_original.nc
<https://www.dropbox.com/sh/m5gebm21z73ng1y/AADky3C3q2mga0WqsyJ57Pbka?dl=0>
is the untainted output file from the bluesky framework.

Matt

And here is where it throws a NPE exception since the expected
