description: This collection offers Sentinel-1 Level-2 Ocean (OCN) products captured in Wave Mode (WV). Level-2 OCN products are specifically processed radar data. These products consist of geo-located geophysical parameters derived from Sentinel-1 Level-1 SAR data and are composed of three components: an Ocean Swell Spectra (OSW) component, an Ocean Wind Field (OWI) component, and a Radial Velocity (RVL) component. The OWI component is a ground-range gridded estimate of the surface wind speed and direction at 10 m above the surface. The OSW component is a two-dimensional ocean surface swell spectrum and includes an estimate of wind speed and direction for each swell spectrum. The OSW component provides continuous measurements of SAR swell spectra at C-band. The RVL surface radial velocity component is a ground-range gridded difference between the measured Level-2 Doppler grid and the geometrical Doppler calculated from Level-1 data. The RVL component provides continuity with the ASAR Doppler grid. OCN products are generated from all four Sentinel-1 imaging modes. In SM mode, the OCN product contains all three components. In IW and EW modes, the OCN product contains only OWI and RVL. In WV mode, the OCN product contains only OSW and RVL.
