Sine M. Hvidegaard

Sine M. Hvidegaard serves as Senior Advisor at DTU Space, Technical University of Denmark, specializing in geodesy and Earth observation for cryosphere research. Her work focuses on satellite and airborne monitoring of ice sheets and sea ice in Greenland and the Arctic, contributing to UN Sustainable Development Goals for climate action and life on land.

Her research spans ice sheet dynamics, satellite altimetry validation (CryoSat), and AI-driven sea ice charting. She develops multi-frequency radar systems for snow/ice thickness measurements and leverages citizen science for data validation, with expertise in Greenland ice loss, Arctic sea ice concentration, and polar climate feedback mechanisms.

Publications since 2020 reveal a strategic shift toward integrating machine learning with remote sensing data, enhancing sea ice mapping accuracy while expanding sensor capabilities for auroral and atmospheric studies through novel instrumentation like dynamic vision sensors.

Hvidegaard actively mentors doctoral researchers in critical environmental projects:

• CH₄ emissions monitoring (2025-2028): Supervising L. A. Klotz's PhD on reconciling top-down/bottom-up methane estimates for waste sectors
• Satellite greenhouse gas tracking (2024-2027): Guiding P. Fabregat Carrascal's GasSat research
• AI for Arctic sea ice charting (2021-2024): Main supervision of A. R. Stokholm's PhD

She leads DTU Space's Cryosphere group, collaborating with ESA on CryoVEx campaigns and managing field operations in Greenland/Svalbard using airborne laser-radar systems and Arctic Trucks citizen science initiatives.
