The dataset consists of ocean surface wind speed and direction at 10 m height and 1 km spatial resolution around the wider Australian coastal areas, spanning 4 years (2017 to 2021) of measurements from Sentinel-1 A and B imaging Synthetic Aperture Radar (SAR) platforms. The winds have been derived using a consistent SAR wind retrieval algorithm, processing the full Sentinel-1 archive in this region. The data are appropriately quality controlled, flagged, and archived as NetCDF files representing SAR wind field maps aligned with satellite along-track direction. The data have been calibrated against Metop-A/B Scatterometer buoy-calibrated, wind measurements and examined for potential changes in calibration over the duration of the data. The calibrated data are further validated by comparisons against independent Altimeter (Cryosat-2, Jason-2, Jason-3, and SARAL) wind speeds. Several methods for data access are also listed. The database is potentially useful for offshore industries (oil and gas, fisheries, shipping, offshore wind energy), public recreational activities (fishing, sailing, surfing), and protection and management of coasts and natural habitats.
该数据集包含澳大利亚沿海地区更广泛地区的 10 米高度处的海洋表面风速和风向，以及 1 公里的空间分辨率，涵盖了 4 年（2017 年至 2021 年）来自 Sentinel-1 A 和 B 成像合成孔径雷达 (SAR) 平台的测量数据。这些风是使用一致的 SAR 风检索算法从完整的 Sentinel-1 档案中得出的，该算法适用于该地区。这些数据经过适当的质量控制、标记，并作为 NetCDF 文件存档，代表与卫星沿轨道方向对齐的 SAR 风场图。这些数据已经过与 Metop-A/B 散射计浮标校准的风测量值进行校准，并检查了在数据持续期间校准可能发生的变化。经过与独立高度计（Cryosat-2、Jason-2、Jason-3 和 SARAL）风速的比较，对校准后的数据进行了进一步验证。还列出了几种数据访问方法。该数据库对于近海产业（石油和天然气、渔业、航运、海上风能）、公共娱乐活动（钓鱼、航海、冲浪）以及海岸和自然栖息地的保护和管理具有潜在的用途。
