# netcdfWriter Configuration

The netcdfWriterConfig gives the opportunity to set some features explicit only for netcdf-files, i.e. file-format (netcdf3/4) or compression.

It is also possible to add an ncml Configuration to the output to change the internal structure just before writing.

It is also possible ot change units including all value in the netcdfWriterDoc. Changing the units in the ncmlConfiguration would change the attribute value only, but not the data.

The CDM resembles a netcdf datastructure. In general, there is no need to use a configuration for this writer, but it might be useful in the following cases:

- Output-files are to big, and a change of datatype i.e. from float to short is desired
- Different attribute are required for special usages, but the input-configuration of the reader shouldn't been changed.
- Different variable or dimension names are required for special usages.
