SWOT Observations Over Sea Ice: A First Look

Geophysical Research Letters
We present a first examination of observations from the surface water and ocean topography (SWOT) mission over the polar oceans. In SWOT, bright, quasi‐specular leads are associated with lower heights relative to the surrounding ice cover.

Reconstruction of Wide Swath Significant Wave Height From Quasi‐Synchronous Observations of Multisource Satellite Sensors

Earth and Space Science
Global sea wave monitoring is of utmost importance for tasks such as analysis of ocean climate change, offshore fisheries, and early warning of marine disasters. Significant wave height (SWH) is one of the most vital and widely used metrics for measuring

Altimeter Calibrations in the Preliminary Four Years’ Operation of Wanshan Calibration Site

Remote Sensing
In order to accomplish the calibration and validation (Cal/Val) of altimeters, the Wanshan calibration site (WSCS) has been used as a calibration site for satellite altimeters since its completion in August 2019. In this paper, we introduced the WSCS and
