...

These Terms of Use are complemented by the complete technical description of the DSS JupyterHub Service and the ECMWF Data Protection and Privacy Statement, unless otherwise expressly stipulated herein.

Subject of the Terms of Use

Jupyter

...

The use of JupyterHub in DSS as described in these Terms of Use is hereinafter referred to as ‘DSS JupyterHub Service’ or ‘Service’.

Registration

DSS JupyterHub Service is available to all DSS users registered with the respective data store, serviced by DSS. No additional registration is needed.

Access

DSS JupyterHub Service is available from the ECMWF JupyterHub launcher page, linked from the respective data store web site. Access requires ECMWF log-in credentials, including a two-factor authentication.

...

DSS JupyterHub Service may be unavailable from time to time for scheduled maintenance or due to unforeseen circumstances. Furthermore, during busy periods DSS users may have to wait for resources to become available before a session is allocated.

Description of the Service

For the complete technical description of the DSS JupyterHub Service please refer to the JupyterHub for ECMWF's Data Store Service Services (DSS) description page. For avoidance of doubt the complete technical description of the DSS JupyterHub Service forms an integral part of these Terms of Use. While the following elements are specifically noted herein, all aspects detailed in the complete technical description of the DSS JupyterHub Service are applicable and enforceable as part of the DSS JupyterHub Service.

Available Environments

DSS users are able to spawn JupyterLab sessions, by means of the DSS JupyterHub Service, with one of the environments summarised in the environments available to DSS users section in the complete technical description of the DSS JupyterHub Service.

To ensure fair usage of DSS JupyterHub Service and/or the respective data store, ECMWF reserves the right to prioritise smaller (and shorter) JupyterLab sessions before others.

Pre-installed Software

The pre-installed Python environments provided are created using conda-forge

...

DSS users can install additional packages from the conda-forge channel (`conda install PACKAGE-NAME`), or from PyPi (`pip install PACKAGE-NAME`). These packages will be installed in the DSS user’s Private Storage and will be available next time the DSS user creates a JupyterLab session. For such packages and other software, additionally installed by the DSS user Articles 5.3-5.5 below shall apply.

User Storage

DSS JupyterHub Service is provided with two forms of storage: Private and Scratch, as described below. 

Private Storage

Each DSS user has Private Storage allocation, which is accessible only to the given DSS user. For the size of this private storage alllocation, please refer to the technical description of the DSS JupyterHub Service.

...

DSS JupyterHub Service provides a git plugin between the DSS user’s Private Storage and git repositories, which the DSS user may use to back up any files stored in their Private Storage.  For avoidance of doubt, back up of any data on either storage forms is not provided as part of the DSS JupyterHub Service.

Scratch Storage

Each DSS user will have a temporary Scratch Storage with a maximum quota per each DSS user on a temporary scratch disk. For the size of the the maximum quota, please refer to the technical description of the DSS JupyterHub Service. If the individual quota is exceeded, automated scripts will delete the oldest files (in terms of file modification time) until the quota is no longer exceeded.

...

The purpose of the Scratch Storage is to store files for a current JupyterLab session or several JupyterLab sessions and such files shall not be considered permanently stored. The Scratch Storage is mounted on a shared disk 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.

Shared Resources

There is a shared resources directory available for the DSS JupyterHub Service. This shared resources directory is ‘read only’ and contains resources provided by Copernicus Climate Change (C3S) and Copernicus Atmospheric Monitoring (CAMS) services and ECMWF, including but not limited, the notebooks found in the C3S training material.

External Network Access

For security reasons, secure shell (SSH) protocol connections are disabled with respect to the DSS JupyterHub Service.

DSS users can use the hypertext transfer protocol secure (HTTPS) address to access repositories outside DSS and/or the DSS JupyterHub Service, given they are not forbidden by the ECMWF firewall.

Technical and Security Requirements

DSS users are responsible for all activities that occur under their account and shall ensure that their content or service will not violate any applicable law. The DSS users are responsible for properly using the DSS JupyterHub Service to secure and protect their accounts in a manner that provides appropriate security and protection from unauthorised access, including but not limited to maintaining the confidentiality of and protecting their access credentials (e.g. private keys or passwords).

...

If a DSS user becomes aware that their account is compromised or becomes aware of any non-permitted activity or any other security breach, they shall immediately change their password and contact ECMWF via support portal.

Purpose of use and Acceptable Use

DSS users are responsible for ensuring that the use of the DSS JupyterHub Service, as well as any data, content and information stored on DSS infrastructure is aligned with the purposes, objectives and activities of ECMWF and the Copernicus services (C3S, CAMS and CEMS) and is in compliance with the applicable laws.

...

Further to any other available remedies to ECMWF as per these Terms of Use or the applicable laws, serious violations may be reported to law enforcement authorities and/or could result in criminal and/or civil liability.
