Timeliness of Correcting Baseline Error in Wide-Swath Altimeter Based on Reference Topography Data
Remote Sensing, 2023 The baseline error is a primary error source of the wide-swath altimeter, directly related to the cross-track distance, and can lead to serious height errors at the swath’s outer edge.

Inversion method of deflection of the vertical based on SWOT wide-swath altimeter data
Geodesy and GeodynamicsThe deflection of the vertical (DOV) is the key information in the study of ocean gravity field. However, in most areas, the precision of the prime component of DOV is significantly lower than that of the meridian component. To obtain higher accuracy and

Estimating Seafloor Topography of the South China Sea Using SWOT Wide-Swath Altimetry Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe surface water and ocean topography (SWOT) wide-swath altimetry satellite was launched in December 2022. The performance of novel wide-swath altimetry in seafloor topography modeling needs to be evaluated. This study utilized 15 cycles of SWOT Level-3 product to construct seafloor topography model of the South China Sea by linear regression analysis.
