This dataset contains the Sentinel-1 SAR IW Remote Sensing Integrated Sea State Parameter product, which forms part of the ESA Sea State CCI version 4.0 release. Sentinel-1 Extra Wide Swath Mode (EW) is similar to the IW mode, but the EW mode acquires data over a wider area than for IW mode using five sub-swaths. The EW mode acquires data over 400 km swath width with a coarser pixel spacing of 40 m (GRDM products) and 25 m (GRDH). This product provides along-track primary significant wave height measurements and secondary sea state parameters, calibrated with CMEMS model data and reference in situ measurements at 17.5 km resolution over each image, processed with the SAR-SeaStaR (SAR Sea State Retrieval) algorithm used developed at the DLR, separated per satellite and image, including all measurements with flags and uncertainty estimates. These are expert products with rich content and no data loss. The SAR EW data used in the Sea State CCI SAR EW onboard Sentinel-1 Level 2P (L2P) ISSP v4 dataset come from the Sentinel-1 satellite missions spanning from 2014 to 2024 (Sentinel-1 A, Sentinel-1 B).
