Correct. It can potentially work with it through the JNI.
Here is a package to make that easier:

Dear Maarten
What you write about pixeltime as an aux coord var (y,x) and your ncdump look
sensible to me. I think that's all fine.

John Caron asked for preferences for the default ellipsoid. I'm not an
expert, but I vote for WGS84 ellipsoid, because it is the modern,
recommended ellipsoid and seems to be the most widely used these days.

All, I meant to send the following to the list yesterday but I don't think it
came through... Hopefully this one makes it through.
New to the list, Rich Signell asked me if I'd respond to John's question below.
For what its worth:
I've done a fair amount of thinking and asked a lot of questions

I imagine the vast majority of netcdf datasets fall into this camp. I

Yes, I noticed that the GRIB keywords name and shortName had

Dear Jakob,
To try to answer your specific query first: the correct spelling of the
standard name is lwe_thickness_of_atmosphere_water_vapor_content. You are
correct that standard names should always use the American spelling. The units
associated with this standard name are m and the explanat
Hi,
For GRIB Edition 1, the meaning of parameter number 137 depends on
originating center (98 = ECMWF in this case) and version number of GRIB
table (indicated at octet 4 of Section 1). It's completely up to ECMWF to
define it, but my understanding is that tables coming with GRIB-API softwar
Hi Jonathan,
Thank you for your reply!
The standard_name time_offset (s) seems good to me. In the long name we
can add an explanation that this variable deals with the time offset for
each pixel.

Hi John, hi all,
I know that for Topex/Poseidon and Jason-1/2 satellite data a specific
reference ellipsoid is used. If ESRI pick a sample of Jason data, as far as I
remember this reference ellipsoid is declared in the netCDF files. They can
retrieve these data on this FTP directory:
