Modèle semi-analytique pour l'altimétrie SAR/Doppler sur océan [PDF]

, 2013
National audienceLe concept de radar altimétrique SAR/Doppler est apparu au milieu des années 90. Cette technologie permet de réduire le bruit de mesure (par augmentation du nombre d’observations) et d’augmenter la résolution le long de la trace (along ...

Assessment of Lead Discrimination from CryoSat-2

, 2012
Sea ice is strongly affecting the global climate, and the sea ice extent has been monitored by satellites since 1979. To estimate the Arctic sea ice volume, ice thickness must be determined. The measurements of sea ice thickness are however more difficult to achieve, and encounter limitations due to spatial and temporal variability. The measurements of

CryoSat-2 Sea-Ice Freeboard and Thickness

, 2013
The understanding and predictability of the observed decline of Arctic sea ice depends on the knowledge of its mass balance in a warming environment. While sea ice extent is monitored by passive microwave sensors for decades, only recently its volume is measured by basin-scale sea ice thickness observations of satellite altimetry missions.

Analysis of the Influence of Different Reference Models on Recovering Gravity Anomalies from Satellite Altimetry

Remote Sensing
A satellite altimetry mission can measure high-precision sea surface height (SSH) to recover a marine gravity field. The reference gravity field model plays an important role in this recovery.

A Pan-Arctic Airborne Sea Ice Observation System [PDF]

, 2016
We present an Arctic sea-ice observation system that focuses on unique direct observations of sea ice plus snow thickness. A network of research institutions, the Alfred Wegener Institute, York University and the Norwegian Polar Institute, maintain an ...

Two Decades of Arctic Sea-Ice Thickness from Satellite Altimeters: Retrieval Approaches and Record of Changes (2003–2023)

Remote Sensing
There now exists two decades of basin-wide coverage of Arctic sea ice from three dedicated polar-orbiting altimetry missions (ICESat, CryoSat-2, and ICESat-2) launched by NASA and ESA.
