Hi Simon. In order, to better diagnose this problem, would it be possible to upload the ccam33S147E08km.nc here: http://motherlode.ucar.edu/repository/alias/idvupload Let us know when it is uploaded. Also, tell us a bit more about what you are trying to do with these data so that we can give you a better answer.
