Brief communication: Ice sheet elevation measurements from the Sentinel-3A and Sentinel-3B tandem phase

Abstract

Abstract. Over the coming decade, the quartet of Copernicus Sentinel-3 satellite altimeters will provide a continuous record of ice sheet elevation change. Ensuring consistency of measurement between the four satellites requires rigorous in-flight inter-comparison. To facilitate this, Sentinel-3B was initially flown in a unique tandem formation with Sentinel-3A, enabling near-instantaneous, co-located measurements of surface elevation to be acquired. Here, we analyse tandem measurements of ice sheet elevation, to show that both instruments operate with statistically equivalent accuracy and precision, even over complex ice margin terrain. This analysis demonstrates that both satellites can be used interchangeably to study ice sheet evolution.

Satellite Altimetry: Achievements and Future Trends by a Scientometrics Analysis

“…Another prominent research key word is the terrestrial hydrology, focusing on the river, lake, and reservoir water levels and rating curves using CryoSat-2, ICESat-2, Sentinel-3A/B, and SWOT simulation data [120][121][122][123]. In addition, the Arctic and Tibetan plateaus are hot issues, which primarily involve the study of sea ice, snow, glaciers, and Tibetan lakes and adopt the data of CryoSat-2 and ICESat-2 [124][125][126][127][128]. Finally, we detected a surging of diverse deep learning topics covering nearly all possibilities of satellite altimetry, such as SWH prediction, SSH reconstruction, eddy detection, 3D ocean state estimation, eddy heat flux estimation, and surface current derivation [129][130][131][132][133][134][135][136][137].…”
