I don't think the issue is the format per se (HDF-4 vs NetCDF), but rather
that HDF-EOS uses a metadata convention that is not COARDS; if you ignore
the HDF-EOS junk (usually in the form of global attributes), it is a
bonafide HDF-4 file. With the right DDF you should be able to read this
Level 3 dataset (likely on 1x1 lat lon grid), no need to convert it to
netcdf.   If you have hdf-4 installed, send the result of "ncdump -c
filename" where "ncdump" here is the one that comes with HDF-4.
