This is done by focusing on the optimization of the spatial resolution to improve the accuracy and reliability of the measures of ocean surface wind measures. This improvement can be of great help as offshore wind farms are deployed further out to the sea, so the best resolution is crucial to planning the next placements. SARs imaging high-resolution, can offer a great solution for remote wind sensing in the ocean. The research has four main objectives. The first one is to compare Sentinel-1 Level 1 (L1) and Level 2 (L2) products with in-situ measurements to study their validity and accuracy, as well as their effectiveness in different atmospheric stability scenarios. The second objective is to find the optimal spatial averaging for wind retrievals from Sentinel-1 as the resolution offered is too coarse, and it could improve the noise and accuracy of the wind signals. This is directly related to the third objective, where the improvement of the resolution is aimed at retrieving measures within off-shore wind farms in the presence of wind turbines. To achieve it, a new processing pipeline for SAR retrievals will be proposed as an alternative to the already-processed L2 products delivered by the satellite operators. The fourth objective is to create a handbook of open sources of in-situ wind retrievals on the North Sea for further validation of SAR products. To achieve the objectives, the methodology used incorporates Sentinel-1 SAR data, in-situ meteorological mast, and algorithms for wind profile extrapolation and spatial averaging. The study starts with an overview of different wind retrieval methods using SAR, using intercomparison criteria and the Monin-Obukhov theory. Some of the findings of the research are the improvement of the accuracy of the SAR wind measurements along with an improvement of their spatial resolution. An optimal spatial averaging area for speckle noise reduction was also found, giving enough resolution and an accurate measure from the wind, which are crucial for the application on offshore wind farms planning and monitoring. This study advances on the understanding of SAR wind retrieval, not only in the scientific field but also in the implications on the wind energy industry and its deployment of offshore wind farms.Universitat Politècnica de CatalunyaSalcedo Bosch, AndreuRocadenbosch Burillo, Francisco20242024-07-0520252025-01-27master thesishttp://purl.org/coar/resource_type/c_bdccNAhttp://purl.org/coar/version/c_be7fb7dd8ff6fe43info:eu-repo/semantics/masterThesisapplication/pdfhttps://hdl.handle.net/2117/422865reponame:UPCommons.
