The Scratch Storage is mounted on a scratch disk, which is a shared resource and is cleaned regularly to ensure that the disk does not exceed capacity. Therefore, the lifetime of the storage of files in the Scratch Storage depends on the overall usage of the DSS JupyterHub Service by all DSS users. The cleanup of files is based on the least recently modified files. This means that files stored here should not be considered permanently stored, they should exist for your current session and may or may not be there when you return. 

Shared resources (notebooks-library)

There is a shared resources directory available from the home in the folder titled notebooks-library/ . This ‘read only’ directory contains resources provided by Copernicus Climate Change (C3S) and Copernicus Atmospheric Monitoring (CAMS) and ECMWF, including but not limited, the notebooks found in the C3S training material. When using these notebooks, you can save them to your home directory and edit them as you wish. The notebooks library is managed as a git repository which is cloned each time a session is spawned, for reference the repository is here: https://githubnotebooks produced by ECMWF for working with the data available via the Data Stores Service and other ECWMF data portals, for a summary description of the resources available please expand the text below. If you wish to save any changes to these notebooks, you will need to make a copy of the notebook in your home directory, this can be done via the "save as..." option in the "file" menu in the top left of the JupyterLab interface.
