On September 24th, 2020, in collaboration with the colleagues of the University of Luxembourg Competence Centre, we conducted the 2nd edition of Copernicus MOOC Webinar for Module 2 Accessing Copernicus data and services, with more than 250 participants.

The objective of the second module of the Copernicus MOOC is, in essence, to understand the Copernicus low level ecosystem, focusing in the following learning objectives:
- Understand how to navigate in the Copernicus “labyrinth”;
- Identify the various data types provided by Copernicus and how to access them;
- Know and be able to compare the various services you may use to access and process Copernicus data.

In the ninety-minute webinar, we presented the basics of Synthetic Aperture Radar (SAR) and SAR Interferometry (InSAR), to better understand Sentinel-1 data. The presentation was followed by a one-hour Q&A session. As we saw in the first edition of the Copernicus MOOC in Spring 2020, we were impressed by the number and the quality of the questions raised by the different participants, indicating a clear interest in the use of Copernicus radar data.
