As climate change accelerates across cold regions – particularly the Arctic and Pan-Arctic – scientists from China and Finland are strengthening a long-term research partnership. The collaboration combines China's advanced remote-sensing technology with Finland's world-leading expertise in snow and ice science. Launched in 2018, the joint research program has already produced key breakthroughs in snow physics and microwave remote sensing. CGTN's Liu Jiaxin speaks with a Chinese scientist involved in this cross-border scientific effort.
