Numerical simulation on the choice of space and time windows for altimeter/buoy comparison of significant wave height

摘要

Without full consideration of the potential consequences, a variety of space and time windows have been used in previous studies for compiling collocated satellite/in situ datasets of significant wave height (SWH). In this study, numerical simulations are carried out to examine the impacts of instrument noises, geophysical variabilities and the number of data pairs on the determination of an optimal size of space and time windows for the calibration/validation of altimeter-derived SWH against in situ measurements. As a result, a number of space/time windows are recommended for future altimeter/buoy SWH comparisons.
