FW: [Wrf-users] WRFSI bug: shifted landuse... Is this relevant to us?

[Rob Cermak]

I can reproduce the results as well.  Even before you run the model,
the NCL scripts that generate graphics from the localize_domain step
will show a shift.  This is a 4km grid (polar).

All parameters from the GEOG directory (soil, etc) is shifted.

If there are patches floating around, I'd be happy to test them.
