| Summary: | Maintenance and Update Frequency: continual Statement: The data have also been quality flagged by tagging spectral inversions where one or more of the partitions suffer from 180 degrees of swell directional ambiguity. According to the NetCDF's authors understanding, the source data have been produced by evolving versions of SAR ocean swell spectra inversion algorithm. This is a trial dataset and its cal/val is an area of current active research. Credit Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. Credit CSIRO Oceans and Atmosphere Credit The University of Melbourne Sentinel-1 A and B satellites are part of Europe’s Copernicus Earth Observation program and carry identical C-band Synthetic Aperture Radar (SAR) instruments. Over open-ocean, they operate in wave mode and collect directional wave measurements globally. This dataset contains Sentinel-1 SAR directional ocean swell wave number spectra, spectral partitions and partition bulks in the Australasian region including the Pacific islands, this mission has flown since 2014, with data delivered from July 2015. The data have been homogenised to a single, easily usable format from inconsistent source product by removing various discrepancies such as inconsistencies in wave number bins and values, variables and erroneous measurements over land. The data represented by this record, are presented in delayed mode.
