Context
Among the different services WEkEO offers for all users, the JupyterHub is a development multi-users platform designed to create, run and share Python codes and scripts for data analysis, in virtual Jupyter environments.
Multiple tutorial notebooks are available in the public folder of the JupyterHub, accessible to all WEkEO users, for free. The only requirement is a WEkEO account.
💡 WEkEO Pro Tip: you will find all the available WEkEO notebooks in our Jupyter Catalogue!
⚠️ Your data located on the WEkEO JupyterHub will be removed if you stay inactive during 5 months. You simply need to login and do some work to reset the counter. After 2 months of inactivity, you will receive an email informing you that your data will be archived for 3 months. You need to contact us during this period for the recovery of the backup.

🔍 To learn more, we invite you to check the following article:
Conda environments
As you can see in previous section Computing resources, various conda environments are made available for all users on the WEkEO JupyterHub.
Your Jupyter instance is initialized with default conda environments, that are reset after each session restart, so all other locations unlisted below are not persisted.
🔎 However, you can create custom environment that will be preserved:
💡WEkEO Pro Tip: all the most used Python packages are already installed in the wekeolab environment, including the hda package!
Filesystems
On the WEkEO JupyterHub, several filesystems are mounted in different locations:
Public folder
Accessibility: public
Location:
/home/jovyan/publicDescription: a read-only filesystem that contains code examples, where you can find notebooks demonstrating how to download data from WEkEO or corresponding to the training sessions on Atmosphere, Climate, Land and Marine applications
⚠️ To be able to modify and save a notebook from the public folder, first you need to copy/paste it into your working directory:
Manually: right click on the notebook, click on Copy, go to your own working directory and right click>Paste
Command Line Interface: run this command in a terminal:
cp public/wekeo4oceans/learn-olci/1_OLCI_introductory/1_1b_OLCI_data_access_HDA.ipynb <OUTPUT_DIR>
where
<OUTPUT_DIR>is the target directory.
Old files folder
Accessibility: private
Location:
/home/jovyan/old_filesDescription: a read-only filesystem that contains the files you may had before the migration on June 14th, 2022
Personal filesystem
Accessibility: private
Location:
/home/jovyanDescription: a filesystem that contains your persistent folders and files.
💡 WEkEO Pro Tip: you can your own folder by right-clicking on the empty space in the file explorer, then New Folder:
