Bo Galle

Professor Emeritus Bo Galle, from the Department of Space, Earth and Environment at Chalmers University of Technology, has made significant contributions to atmospheric studies and volcanic gas monitoring over a career spanning more than 35 years. Specializing in optical remote sensing methods, Galle's work in the past decade has focused on studying gas emissions from volcanoes, leading to the development of an innovative early warning system for volcanic eruptions using differential optical absorption spectroscopy (DOAS). As coordinator of EU projects DORSIVA and NOVAC, he spearheaded the installation of measurement technology on numerous volcanoes globally, with his system now deployed at over 200 stations across 60 volcanoes in 22 countries. Galle's groundbreaking work, which earned him the Chalmers impact award, has not only advanced volcanology but also contributed to saving lives through early detection of volcanic activity. His expertise continues to shape the field through his teaching contributions to courses on Earth sensing and environmental science at Chalmers, cementing his legacy as a pioneer in volcanic gas monitoring and environmental research.
