The Integrated Carbon Observation System, ICOS, provides standardised and open data on greenhouse gas concentrations in the atmosphere, carbon fluxes between the atmosphere, the land surface and the oceans, as well as elaborated data products based on the ICOS observations. To complement the data discovery functionalities of the ICOS Carbon Portal, ICOS is offering a set of Notebooks written in the Python language. The audiences for the Notebooks range from the interested general public, who want to explore ICOS data and learn about greenhouse gases and climate change, to advanced scientific users who use the Notebooks to develop new algorithms and collaboratively analyse data to solve current research questions. The public Exploredata JupyterHub is open to everyone, and to start using it all that is required is to request a password. It offers many introductory Notebooks to explore data, many of which do not assume any knowledge of Python or programming. The examples range from how to access data and create interactive plots, to a quiz about the carbon cycle, as well as materials used in educational settings. Our collaborative JupyterHub service for registered users offers more advanced options like sharing notebooks and data between users, uploading users’ own data for analysis together with ICOS data, and permanent storage of notebooks and data. This service is continuously expanded in close consultation with our end user communities to support their scientific analysis and interpretation of ICOS data and products.
