Hi Marta,

I'm not sure what you mean by a "simple binary file".  Do you want an
unformatted Fortran binary file?  In that case, the simplest thing to
do would be to write a small Fortran program that opens the netCDF
file, (using the nf90_open function for example), reads a variable a
slice at a time (using the nf90_get_var function, for example) and
writes the data to another file using a Fortran unformatted write
statement.  These functions are documented in the NetCDF Fortran 90
Interface Guide, available online from

  http://www.unidata.ucar.edu/software/netcdf/docs/

If you want to write a binary file that you will access from C, C++,
Java, or some other scripting language, you may have to write a small
program in that language that uses the appropriate netCDF language
interface to read the data and write it out in the way you desire.

If you just want to see data values for some variable in text form,
you can use the ncdump utility that is part of the netCDF software.
For example, to see just the variables "T" and "P" in the file
wrfout.nc, you could run the program

  ncdump -v T,P wrfout.nc
