Atmohub & Climatehub: Greece's Hubs for Climate and Air Quality

Atmohub and Climatehub serve as key information hubs for energy, climate change, and atmospheric composition in Greece. Atmohub, within the framework of the CAMS National Collaboration Programme (CAMS-NCP-Greece) of the Copernicus program, specializes in atmospheric composition, offering insights into air pollution and air quality. On the other hand, Climatehub, supported by the C3S Copernicus Climate Change Service National Collaboration Programme (C3S-NCP), focuses on providing valuable data and analyses related to energy and climate change. Both hubs contribute to enhancing the understanding of critical environmental issues and supporting informed decision-making at the national level.
