Markus Rex is a German atmospheric physicist and polar researcher noted for leading large-scale Arctic field campaigns and for contributions to observational meteorology and climate science. He served as a principal investigator and expedition leader for multinational programs, coordinating research across institutions, vessels, and aircraft. His work integrates observational platforms, numerical modeling centers, and international research organizations to study Arctic processes and global climate linkages.
Rex studied physics and meteorology at the Technical University of Munich and completed advanced studies at the University of Cologne, where he trained in atmospheric physics, boundary layer processes, and observational techniques. During his doctoral and postgraduate training he collaborated with groups from the Max Planck Society and research centers such as the German Aerospace Center. His formative education included field courses and campaigns linked to polar stations like Ny-Ålesund and institutions including the Norwegian Polar Institute.
Rex's professional career has been anchored at the Alfred Wegener Institute (AWI), where he progressed from project scientist to senior leadership roles within polar and climate programs. At AWI he coordinated logistics and science planning with partner organizations including the European Space Agency, World Meteorological Organization, and national polar institutes from United States, Canada, Russia, Norway, and Japan. His career includes collaboration with university groups at the University of Bremen, the University of Hamburg, and international modeling centers such as the European Centre for Medium-Range Weather Forecasts and the National Center for Atmospheric Research.
Rex has directed airborne campaigns using platforms operated by agencies like Deutsches Zentrum für Luft- und Raumfahrt and international research vessels registered to institutions including the University of Tromsø and the Alfred Wegener Institute’s polar fleet. He has been involved in coordinating data streams with observational networks such as GCOS and satellite missions from NASA and ESA.
As leader of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, Rex coordinated an international consortium of research institutions, funding agencies, and operational partners. MOSAiC brought together icebreaking vessels, research stations, and aircraft from countries including Germany, United States, Norway, Russia, China, and Japan to conduct yearlong observations across the Arctic. Under his leadership the expedition implemented an integrated measurement strategy linking surface flux towers, autonomous instruments, cloud radars, and oceanographic moorings to modeling teams at centers such as ECMWF, NOAA, and DWD.
Rex managed complex logistics involving icebreaker coordination with vessels like Polarstern and support from national polar programs, arranging international science schedules, permitting, and data sharing agreements among organizations such as the International Arctic Science Committee and the Intergovernmental Oceanographic Commission. The MOSAiC mission generated dense datasets used by climate researchers at institutions including Scripps Institution of Oceanography, Woods Hole Oceanographic Institution, and the University of Alaska Fairbanks.
Rex’s research focuses on Arctic boundary layer meteorology, cloud microphysics, and atmosphere–ice–ocean interactions. He has advanced observational strategies combining in situ sensors, remote sensing from instruments like cloud radars and lidars, and synergies with satellite missions from NOAA, ESA, and JAXA. His publications address polar amplification, sea ice thermodynamics, and aerosol–cloud interactions, informing modeling efforts at NCAR, ECMWF, and national climate services such as Met Office and DWD.
He has contributed to the development of instrument suites and deployment protocols used on floes, icebreakers, and aircraft, linking measurements to process studies employed by modeling groups at the Max Planck Institute for Meteorology and university research groups at ETH Zurich and MIT. His data stewardship practices emphasize FAIR principles and collaboration with data repositories operated by organizations including PANGAEA and the World Data Center system.
Rex has received recognition from polar research communities and scientific societies for leadership in Arctic science. His role in coordinating multinational science campaigns has been noted by organizations such as the International Arctic Science Committee and national funding bodies including the German Research Foundation. He has been invited to present findings at major conferences like the American Geophysical Union Fall Meeting and the European Geosciences Union General Assembly, and has been cited in assessments produced by the Intergovernmental Panel on Climate Change.
Rex is affiliated with research and professional organizations including the Alfred Wegener Institute, the Max Planck Society, and university departments such as the University of Bremen. He collaborates with international consortia comprising institutes like AWI, NOAA, NASA, and the Norwegian Polar Institute. Outside professional duties he has engaged in outreach activities with public institutions and educational partners such as museums and science centers in Germany and partner countries.
