Strange longitudes from this grib file

[GoogleCodeExporter]

loc2='dods://geoport.whoi.edu/thredds/dodsC/usgs/data2/sdalyander/nam_wind/nam_a
gg7.ncml'
ncNAM=ncgeodataset(loc2);
ncgrid=ncNAM{'u_wind'}(:).grid;
latNAM=ncgrid.lat;
lonNAM=ncgrid.lon;
pcolorjw(lonNAM,latNAM,double(lonNAM));colorbar

Produces a very strange map, because the longitude, instead of spanning the 
continental US ([-150 -50]), ranges from -520.66 to 330.7866.

I tried accessing this dataset in the toolsUI in NetCDF4.0, 4.1 and 4.2 and 
none of them work, so this seems to be a NetCDF-Java problem.  I will take this 
up with John Caron. 

Soupy Dalyander (sdalyander@usgs.gov) says this used to work with a previous 
version of Matlab and njTBX, which is strange, because I don't see how this 
could be if netcdf-java isn't doing it correctly.  Unless Sachin Bhate (the 
njTBX developer) introduced extra code as a workaround.

Mystery solved -- sort of.

I turns out that toolsUI-4.0.49.jar produces the *correct results*
while later toolsUI versions do not work.

I tried swapping out the latest toolsUI-4.2 for toolsUI-4.0.49.jar in
NCTOOLBOX, and NCTOOLBOX then works fine for this case.

I'll pursue this with John Carone.

Seems to work fine in my reference installation of nctoolbox. (Using separate 
jars including netcdf version 4.2) Appears to only affect previous versions of 
netcdf-java.

Current versions of nctoolbox should not have this problem.

Interesting.  I confirm this finding.  But the jars in the nctoolbox/java 
directory are apparently *not* the latest jar files from Unidata.  So while the 
latest NCTOOLBOX using the supplied jars works, the latest jars from Unidata do 
*not* work.  So I will still persue this with John Caron.
