[ncl-talk] read netcdf file

[Cathy Smith]

Hi

As the file was obtained from NOAA/PSD, I should say that ncdump works 
fine on the file (and on netCDF4 files in general). Perhaps the version 
of ncdump which Soma is not current  (e.g. has HDF5 support). Also, I 
can't tell from this thread, but possibly Soma did not download the file 
completley or it was corrupted during transfer (which would give that 
error). I believe ncl_filedump would also fail then (but perhaps not; 
maybe it can deal with incomplete netCDF files).
