Hi!  I was testing out the latest TDS snapshot.  I've run across some
problems that I'd like to report.

   - Server: [image: THREDDS Data Server] THREDDS Data Server
   - Webapp Name: THREDDS Data Server
   - Webapp Version: 4.3.14-SNAPSHOT
   - Webapp Version Build Date: 20121020.1514
   - Abstract: Scientific Data

Dataset: grab one of WRF (wrfout) from here:

http://weather.arsc.edu/Operational/HRRR-AK/Products/wrfout/2012110512/wrfout_d01_2012-11-05_12:00:00

Summary: Godiva2 shows the fields just fine, but clicking on "test image"
or "Open in Google Earth" produces a cropped image.  Adjusting the  long
variable I can obtain the full field.  "Fit layer to window" does not
center over the dataset.  Moving the view does show the entire layer
properly.

It looks like the server is open to the Internet so the links should work.
 I will attach some snapshots just in case.

Clicking on test image gives:

If I adjust the BBOX to say -190.0, I can get the full field.

I believe this seems like a computational error for datasets that drape
over 180 degree line.  The image for google earth is also cropped
(attached).

Is there metadata info we can add to the NetCDF file to the catalog make it
better behaved?

Thanks!
Rob
