Hi,

There are two utility programs that come with netCDF, ncdump and ncgen, that 
can be used to convert between ASCII and netCDF.  The ASCII form of the data is 
called "CDL", and it represents the structure and metadata as well as the data. 
 For a description and examples, see:

 http://www.unidata.ucar.edu/software/netcdf/docs/netcdf.html#NetCDF-Utilities

You use ncgen to convert from the CDL form to netCDF and ncdump to convert 
netCDF to CDL.  To get from the ASCII form you have to the CDL ASCII form, you 
may have to use some editing or text-processing tools.

You can also use "ncgen -f" to generate the Fortran code needed to create a 
netCDF file from CDL.  This is often the easiest way to get started creating a 
Fortran program for netCDF data.

To see more example CDL files as well as example programs that create netCDF 
files, you can also look at this examples page:
