Copernicus Marine Service Toolbox (CLI & Python)

IMPORTANT: This is a pre-release that can be used for testing purposes. The behavior and some features might change in a near futur.

Features

The Copernicus Marine toolbox offers capabilities through both Command Line Interface (CLI) and Python API:

• Metadata Information: List and retrieve metadata information on all products, datasets, variables.
• Subset Datasets: Subset datasets to extract only the parts of interest, in preferred format, such as Analysis-Ready Cloud-Optimized (ARCO) Zarr or NetCDF file format.
• Advanced Filters: Apply simple or advanced filters to get multiple files, in original formats like NetCDF/GeoTIFF, via direct Marine Data Store connections.
• No Quotas: Enjoy no quotas, neither on volume size nor bandwidth.

Documentation

The full documentation of the toolbox is available here: Copernicusmarine Documentation. Please refer to it for the more exhaustive and up to date documentation.

You might also find more comprehensive details on how to use the copernicusmarine Toolbox, please refer to our Help Center. It ensures a smooth migration for existing users of legacy services such as MOTU, OPeNDAP or FTP.

Python package (API)

The copernicusmarine exposes a Python interface to allow you to call commands as functions.

Version management

We are using semantic versioning X.Y.Z → MAJOR.MINOR.PATCH → for example 1.0.2. We follow the SEMVER principles:

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes
• MINOR version when you add functionality in a backward compatible manner
• PATCH version when you make backward compatible bug fixes

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
