[netCDF #ERY-773358]: (regular real*4 or real*8) binary file to netCDF

Hi Arlindo,

No, primarily for these reasons:

  - There is no standard for the format of a "(normal) binary file".
    Binary files written from different languages and different 
    operating systems can be wildly different.
  - Binary files typically have no metadata describing the data they
    contain, and netCDF files require such metadata to make the file
    "self describing".  For example, a netCDF file must contain names
    for all variables, as well as specifications of their types and
    shapes (e.g. the "dimensions" used to specify common grids).

There are software packages that convert data from one binary
format to another, for example from GRIB to netCDF or HDF-EOS to
netCDF.  However, usually something is lost in such a conversion,
because different formats are based on different conceptual models 
of the data.

By Googling "converting to netcdf" and similar phrases, you can find
some examples of such software packages.  You can even find software
by searching for "converting binary files to netcdf", but you'll see
that the matches are not very useful, because "binary file" is too
vague ...
