Effects of Interferometric Radar Altimeter Errors on Marine Gravity Field Inversion [PDF]
Sensors, 2020 The traditional altimetry satellite, which is based on pulse-limited radar altimeter, only measures ocean surface heights along tracks; hence, leads to poorer accuracy in the east component of the vertical deflections compared to the north component ...

Combining surface drifters and high resolution global simulations enables the mapping of internal tide surface energy [PDF]
Scientific ReportsBy dissipating energy and generating mixing, internal tides (ITs) are important for the climatological evolution of the ocean. Our understanding of this class of ocean variability is however hindered by the rarity of observations capable of capturing ITs
