[netcdf-java] Problems reading data in polar stereographic projection

[Jon Blower]

Hi all,

I'm trying to use the Java NetCDF libraries (2.2.22) to read Arctic
ocean data over OPeNDAP.  The data are in polar stereographic
projection.  However, the following short program (which works fine
for many other datasets) returns zero Grids:

    NetcdfDataset nc = NetcdfDataset.openDataset(url, true, null);
    GridDataset gd =
(GridDataset)TypedDatasetFactory.open(DataType.GRID, nc, null, null);
    System.out.println(gd.getGrids().size()); // prints out "0"

The URL to the OPeNDAP site is
http://topaz.nersc.no/thredds/dodsC/topaz/mersea-ipv2/arctic/tmipv2a-class1-be.
 The results of performing an ncdump on this URL (using toolsUI) are
attached.  toolsUI also fails to recognize any Grids in this dataset.

Can anyone advise on what might be the problem here?  Is the metadata
of the dataset incorrectly specified?

Thanks in advance,
Jon
