Compression

If the package enstools-compression is installed, the I/O enstools-io functions provided by enstools can use lossless and lossy compression.

Check more details about the package in:

• GitHub repository

• Documentation

For lossless compression it relies on BLOSC and for lossy compression it relies on ZFP and SZ.

Some examples .. code:

with read("input.nc") as dataset:
    ...
    # Lossless compression with the default parameters
    write(dataset, "output.nc", compression="lossless")
    ...
    # Lossy compression using SZ with the absolute threshold of 0.001
    write(dataset, "output.nc", compression="lossy,sz,abs,0.001")

    # Lossy compression using ZFP with the absolute threshold of 0.001
    write(dataset, "output.nc", compression="lossy,zfp,accuracy,0.001")
