Hi David,
A few ideas:
Can you try to take a slice of your dataset at just the surface level to see if it displays? That could help isolate if it has something to do with the vertical axis. I notice that some of your variables are only defined at 1 level.
Also, could it be a problem that your undef value is different than the missing value and fill value attributes?
