The Earth Observation Laboratory is involved in a wide range of projects covering the entire spectrum from basic to applied research. Here is a selection of some of the larger projects, both current and past.


Arctic Summer Sea Ice in 3D (SI/3D)

SI/3D will close the gap in summer sea ice thickness observations from radar altimetry, harnessing deep machine learning, modelling of the radar altimeter response, and dedicated field campaigns, to overcome the processing barriers. With this unique dataset, we will: (1) close the Arctic sea ice volume budget, pinpointing the mechanisms driving seasonal decay and breakup of the ice pack and the feedbacks of sea ice loss on Arctic temperatures, and (2) upgrade seasonal sea ice forecasts from state-of-the-art modelling systems by assimilating summer ice thickness observations.

air-snow-ice-ocean INTERactions transforming Atlantic Arctic Climate (INTERAAC)

The INTERAAC project assembles a complimentary team of experts from China and Norway to generate a reconciled multi-mission Climate Data Record (CDR) of sea ice properties in the Atlantic Arctic. By integrating SAR, altimetry, and field observations, we will target the inter-mission biases currently preventing detection of climate-relevant trends. Our new data will enable the investigation of coupled air-snow-ice-ocean processes driving sea ice retreat along the Atlantic Polar Front. Funds: NFR-POLARPROG

CryoSat Thematic Products (CryoTEMPO) Summer Sea Ice


The Cryo-TEMPO study aims to deliver a new paradigm of simplified, harmonized, and agile CryoSat-2 products, that are easily accessible to new communities of non-altimeter experts and end-users. The project will generate six new thematic along-track products, covering Winter Sea Ice, Summer Sea Ice, Land Ice, Polar Ocean, Coastal Ocean and Inland Water, using rapidly evolving, state-of-the-art processing dedicated to each thematic area.

Arven etter Nansen (The Nansen Legacy)

The Nansen Legacy is a joint plan to follow Nansen's example in exploring the Arctic and establish a holistic understanding of a changing Arctic Ocean and ecosystem. The project will provide the scientific knowledge base needed for future sustainable resource management in the transitional Barents Sea and the adjacent Arctic Basin. Funds: NFR & partners
Host: UiT The Arctic University of Norway

Sea Ice Retrievals and data Assimilation in NOrway (SIRANO)

The SIRANO project, a collaboration between MET and UiT, focuses on enhancing sea-ice predictions in the Arctic regions. It emphasizes integrating detailed images from diverse satellites, like Synthetic Aperture Radars and Microwave Radiometers, with advanced computer models. The project's success will benefit maritime navigation, search and rescue operations, and weather forecasting in Norway. Funds: NFR-ROMFORSK
Host: Met Norway
PI: Thomas Lavergne


Center for integrated remote sensing and forecasting for Arctic operations (CIRFA)

A centre for research based innovation (SFI), hosted at UiT The Arctic University of Norway, focusing on detecting, characterizing, mapping, and forecasting of Arctic sea ice, icebergs, ocean surface currents, wind, polar-lows and marine pollution. Funds: NFR & partners
Host: UiT The Arctic University of Norway
PI: Torbjørn Eltoft

Sea Ice Deformation and Snow for an Arctic in Transition (SIDRiFT)

SIDRiFT focuses on understanding Arctic sea ice deformation and its impact on climate and navigation. Utilizing satellite data, field observations, and numerical models, the project studies ice floe dynamics, cracks, snow distribution, and their effects on ice growth and melting. Collaborating with the MOSAiC expedition, SIDRiFT aims to enhance Arctic weather models and develop new satellite sensors for ice observation, key for future climate strategy and navigation.
