- --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
