The WEkEO DIAS provides not only a single place to download and visualize Copernicus data, it also proposes a full gallery of Jupyter notebooks located in its cloud-based infrastructure. Every user can access to the catalogue, you only need to create an account for free.

You can run the notebooks in your own WEkEO JupyterHub workspace (accessible from your Dashboard > JupyterHub). To find a specific notebook, you can look into the public repertory and the folders inside, or you can search directly in the Jupyter Catalogue using the filters as we will show in this article.

Without any further ado, let's dive into the Jupyter Catalogue! 😃

When we arrive on the page, we see all the notebooks of the catalogue.

In order to search for a specific notebook, we can use some filters in the sidebar:

You can also click on one item of the header, for example ATMOSPHERE, and it will show the sidebar with your item already selected.

Let's say for the purpose of this article that we are interested in an introductory notebook about how to access OLCI instrument data.

We can select the OLCI parameter in the Sensor section:

As you will see, when you select a parameter in a section, some of them disappear and others remain. It is due to the fact that behind the scene, there is an AND operator

displaying the only parameters left when applying an intersection with the selected ones. The result of the next operation is visible in parenthesis.

In other words, in our example, there would be only one notebook left if we click on MSI, but now there are 13 notebooks listed on the right.

We will take for our example the notebook OLCI data access via the WEkEO HDA adaptor. Click on the notebook to open it in a new page.

On this page there are:

Click on Open in Jupyter to open the notebook in your WEkEO JupyterHub environment (you only need an account). If you're not logged in yet, sign in to your WEkEO account in the new opened window.

Choose one of the proposed server (see differences between both) and press Start:

You should arrive on your JupyterHub environment with the notebook opened in a new tab:

You can now run the cells but not modify directly this notebook because it is located in the public directory.

You have also the possibility to open the notebook in the WEkEO GitHub.

Simply click on Open in GitHub to reach the corresponding page of the notebook.

It will show the notebook as an overview. From this page, you can use the GitHub functionalities such as clone etc.

Once in GitHub, you can always browse through the different folders of the wekeo repository. For example, you will find more information about the OLCI notebooks in the wekeo/learn-olci path:
