High-resolution, calibrated and validated Synthetic Aperture Radar ocean surface wind data around Australia

The dataset consists of ocean surface wind speed and direction at 10m 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 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.The ongoing IMOS (Integrated Marine Observing System) Surface Waves Sub-Facility SAR wind database (delayed mode data) is available through the Australian Ocean Data Network (AODN) Portal (https://portal.aodn.org.au/search?uuid=b02b929f-2caf-45d4-ac60-d4632b7ca0ca), the main repository for marine data in Australia. The data represented by this metadata record is a snapshot of the database at the time of this publication (November 2022), and has been assigned a DOI and will be maintained in perpetuity by the AODN.
