[NARCCAP-discuss] NARCCAP netcdf file viewer?

[Seth McGinnis]

Hi Perdinan,

No, but a very similar fix will solve the problem:

ncatted -a false_easting,polar_stereographic,o,d,4700000 filename.nc
ncatted -a false_northing,polar_stereographic,o,d,8400000 filename.nc

BTW, this is one of many small metadata cleanups we have on our to-do list.  It
doesn't take that long to do each one, but if we change a file on ESG, it
requires a significant amount of work to get it republished.  So we've been
working on the collection of fixes in such a way that we can do one big update
all at once when they're all done.  Apologies to all for the resulting
inconvenience...

Cheers,

--Seth
