Along-Track Resolution and Uncertainty of Altimeter-Derived Wave Height and Sea Level: Re-Defining the Significant Wave Height in Extreme Storms (JGR-Oceans 2024)

This paper shows that the altimeters measure waves over a footprint that has a doughnut shape and discusses what should be the proper definition for the significant wave height definitions altimetry
