Delivering a virtual training course on the use of the Sentinels for various selected applications (agriculture, disasters, atmosphere…it can be adapted using the outputs of the WGCapD annual meeting / requests from UN), where a closed group of around 30 pre-selected attendees is given access for 4 weeks to the ESA EO Open Platform, which contains Jupyter Notebook. Theory sessions may complement this, if needed. Possibly we may capitalize on the efforts of past webinars developed by NASA ARSET, ESA and UNOOSA (for the theory) in 2021 and early 2022. Other WGCapD members are welcome to collaborate and bring their Notebooks.
