- -h
-
Prints a help text.
- -v
-
Show more information.
- -o
-
Overwrite destination file.
- --complevel=(0-9)

Sets the compression library to be used during the copy. lib can be set to "zlib", "lzo" or "ucl". Defaults to "zlib".
- --shuffle=(0|1)
-
Activate or not the shuffling filter (default is active if complevel>0).
- --fletcher32=(0|1)
-
Whether activate or not the fletcher32 filter (not active by default).
- --unpackshort=(0|1)
-
Unpack short integer variables to float variables using scale_factor and add_offset netCDF variable attributes (not active by default).
- --quantize=(0|1)
-
Quantize data to improve compression using least_significant_digit netCDF variable attribute (not active by default). See
