What version of IDL do you have?

From Lajos's reply it would appear you have a netCDF4 file - which uses
HDF5 to handle the hard stuff that classic netCDF couldn't.

Newer versions of IDL "understand" netCDF4. So, if you have an old(er)
version of IDL, that may be your problem. (If, indeed, it isn't what
Lajos indicated - you are trying to read a regular HDF5 file)

I use the IDL netCDF browser to read netCDF3-and-4 datafiles with no
problems.

cheers,
