All DSS JupyterLab sessions running on this service are time limited. When the time is up, the instance will be killed terminated automatically along with any active processing that may be taking place. You can only have one session running. If you left one running, DSS JupyterHub will connect you straight back into it. If the Service is busy and there are no resources available, you will be informed as such and will need to try again later. To ensure fair usage of DSS JupyterHub Service and/or the respective data store, ECMWF reserves the right to prioritise smaller (and shorter) sessions before others. |

This is the general ECMWF JupyterHub launcher, therefore it is possible that you have access to more than the Data Store Service option described here. |

As specified in Article 5.5 of the Terms of Use for ECMWF's Data Store Service Services JupyterHub, it is the DSS user's responsibility to ensure they have all the necessary rights to use any of services, applications (including software), data and products used on DSS via the DSS JupyterHub Service. The software and configuration provided in the initial environment uses open-source channels only (i.e. conda-forge) and we encourage DSS users to use, and contribute to, open source software distributions. |

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.

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://github.com/ecmwf-projects/dss-jupyterhub-notebooks/
