Abstract
• Retracking of altimeter waveforms yields fluctuations in wave height and sea level, correlated at the scale of the effective footprint • A good approximation for the effective footprint diameter is the square root of the product of wave height and satellite altitude • An estimation of phenomenal wave heights precise to better than 2% requires filtering over wave groups, typically over a distance of 20 to 50 km19 Apr 2024Submitted to ESS Open Archive 19 Apr 2024Published in ESS Open Archive
