Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry

Earth and Space Science
Differences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

Bayesian Estimation of Smooth Altimetric Parameters: Application to Conventional and Delay/Doppler Altimetry [PDF]

International audienceThis paper proposes a new Bayesian strategy for the smooth estimation of altimetric parameters. The altimetric signal is assumed to be corrupted by a thermal and speckle noise distributed according to an independent and non ...

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.

Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends [PDF]

Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties.

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.
