Sentinel-1, WW3 and Buoy Spectral Comparisons in the Southern Ocean

Space-borne Synthetic Aperture Radar has the ability to estimate directional ocean swell spectra globally and help answer scientific questions in the understanding of swell systems, cross seas as well as improve sea-state forecasts. However, it is still an open question how well such observations represent the actual spectra. We aim to address this question in the Southern Ocean by comparing these satellite measurements with reference data: wave model spectra and in-situ buoy observations, where available.
