Renée Mie Fredensborg Hansen

Renée Mie Fredensborg Hansen is a Postdoctoral Research Fellow at the Department of Space Research and Technology, Technical University of Denmark (DTU), specializing in satellite altimetry applications for cryospheric research. Her work focuses on polar ice monitoring using advanced remote sensing techniques from missions like CryoSat-2 and ICESat-2.

She earned her PhD from DTU in 2024 with a dissertation on multi-frequency remote sensing of sea ice and snow features. Her educational background includes extensive fieldwork and data analysis training in polar environments.

Hansen's research centers on Satellite Altimetry and Cryosphere Science, with expertise in snow depth estimation over sea ice, Antarctic and Arctic ice dynamics, and multi-sensor data fusion. She actively contributes to understanding climate change impacts through precise measurements of ice sheet elevation and sea ice freeboard.

Her recent publications (2024-2025) reveal a concentrated research trajectory analyzing heterogeneous snow-covered sea ice using CRYO2ICE mission data. Key trends include methodological advancements in multi-frequency altimetry (C/S-, Ku-, and Ka-band), validation of satellite-derived snow depth products against airborne observations, and seasonal comparisons of Arctic winter sea ice properties.

She has received notable recognition including:

• Academicus Arcticus (1st prize, October 2021)

Hansen's research is supported by DTU Space and collaborative projects like her completed PhD work 'Mapping extreme sea ice features from a combination of remote sensing and in situ' (2021-2025). She has conducted field research at the University Centre in Svalbard (2022, 2023) and contributes to open science through published datasets on snow depth and sea ice elevation. While currently focused on independent research, she collaborates extensively with international polar science teams.

Her work operates within DTU's polar research ecosystem, leveraging partnerships with ESA and NASA missions while contributing to UN Sustainable Development Goals related to climate action through cryospheric monitoring.
