Summary: | Maintenance and Update Frequency: notPlanned Statement: The data are appropriately quality controlled, flagged, and archived as NetCDF files representing SAR wind field maps aligned with satellite along-track direction. For full details of quality control procedures applied; data generation workflow; format and file naming conventions see the data paper. Credit Integrated Marine Observing System (IMOS). IMOS is a national collaborative research infrastructure, supported by Australian Government. Credit European Space Agency Credit European Copernicus program Credit Copernicus Australasia regional data hub 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.
