problem with XDF file in 1.9b4

List,
I recently upgraded to 1.9b4 because I was having problems opening xdf files
in 1.8sl11. Every time I opened an XDF file that pointed to a netcdf file -
I could display a variable only once, then it would core dump and die.
1.9b4 solved this problem, however a new problem exists. I am attempting to
plot wind speed/direction and wave heights over Lake Erie. I'm successful
in plotting wave height, however neither wind speed nor direction seem to
want to plot. The wind speed is simply the magnitude of the wind, the
direction is obviously the direction - it's not broken down into u or v
components - not a concern at this point. It seems as if GrADS is having a
hard time finding these variables in the netcdf file in the 1st place...this
is the error I get...
Couldn't find variable Wind_Mag_SFC (aliased to speed) in SDF file.
Data Request Error: Error for variable 'speed'
Error ocurred at column 1
DISPLAY error: Invalid expression
Expression = speed
I've included my xdf file and the headers of my netcdf file below...unless I
missed something - Wind_Mag_SFC is clearly defined in the netcdf file. I get
the same error for direction - that it's not able to find Wind_Dir_SFC.
The strange thing is that if I open this xdf file in 1.8sl11 - it works fine
- except for the nasty core dump problem. The file opens, I can plot
'speed' or 'direction' just fine. Is there something that needs to be added
to my xdf file now that I'm using 1.9b4?
Any help would be appreciated!
Thanks!
