Left: Sentinel-1A acquisition segment in Wave Mode over the Pacific Ocean. The 42 Wave Mode imagettes are indicated as dots and the background colour stands for significant wave height as predicted by Wave Watch 3 (WW3) model run at Ifremer.
Right: ‘Quicklook’ corresponding to one Sentinel-1A imagette. The modulation of the sea surface roughness is caused by swell propagating across the Pacific Ocean. Although Sentinel-1A commissioning is not finished yet, the first data acquired over oceans are already full of promises for ocean wind, wave and current measurements.
