For the activities of the Environment & Climate Research Cluster, the ERATOSTHENES CoE exploits the state-of-the-art infrastructure of the Centre such as the proposed Ground-Based Remote Sensing Station (GBS), Copernicus data and core services, archived satellite images and data from various EO networks, among other equipment, to conduct cutting-edge applied research in this research cluster, which results in effective applications, services, education, and related start-ups. This can be combined with regional and global EO monitoring with ground-based networks, in addition to long-term observations, statistics, and trend analysis over the past decades, which is essential to understanding the processes that link the environment with climate problems. The Environment & Climate research cluster consists, as shown earlier, of the following sectors:
