Hi Steve, I discussed the issue you are seeing with another developer, and our feeling is that we need a sample file to disect to figure out the right way to handle the rotated lat/lon grid. Can you either send us a sample file (if not too large) or upload it to our Dropbox (http://motherlode.ucar.edu/repository/entry/show/RAMADDA/Unidata/Community/TDS+Dropbox?entryid=1be58742-41bc-451b-8e03-9b6c033a52ad)? Note that you will not see your file listed after it is uploaded, but you should see a confirmation of success.
