What is CHOPIN?  is a multi-part documentary about the the 2024-2025 CleanCloud CHOPIN (Cleancloud Helmos OrograPhic sIte experimeNt) campaign at Mt.Helmos, Greece: where mythology, aerosols, clouds and climate meet. This video is the fourth part, Act 4, focusing on the vision and efforts of Dr.Kostas Eleftheriadis and his team at NCSR Demokritos to establish the (HAC)2 station that enabled the study of aerosols, clouds and greenhouse gases for monitoring, science and policy. Together with the combined vision, enthusiasm, efforts and devotion of all campaign partners, CHOPIN and its unique dataset became a reality.
