Since its early days, the Sentinel-1 (S1) Mission has been delivering sea state measurements to both operational and science users.S1 Level-2 Ocean (L2 OCN) operational products currently include Ocean Wind field (L2 OWI…
), Ocean Swell (L2 OSW) and Surface RadialVelocity (RVL). The latter remains not qualified due to limitations of the system and operational algorithms in production today. In the meantime, various ocean science studies have demonstrated that an improved RVL retrieval can be achieved, in particular i
f considering a SAR processing flow tailored to ocean products. Moreover, different studies have also pointed into directions to obtain valuable wave spectrum information from TOPS mode, which would improve the OSW coverage currently limite
