My comments were based on a quick look at the OPeNDAP text data response for 
each dataset ("*.asc?temp[9][0][55:1:154][180]").

Your probably already looking at this but ...

My guess would be that the netCDF-Java library, which is used by the TDS to 
read the netCDF files, is not reading the netCDF-4 file properly. Another guess 
is that the main culprit may be that the TDS (and thus netCDF-Java library) on 
the server is almost two years old (TDS version 4.2.2). Our current stable 
release is 4.2.10.

Looking at the data in ToolsUI should be a quick test. If the latest 4.2 
ToolsUI doesn't read the data correctly, our 4.3 beta release might do better.
