Brief description
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. This dataset contains 10m neutral stability wind speed and direction derived from Sentinel-1 A and B SARs in the wider Australian coastal regions. In these regions, the satellites normally operate in interferometric wide (IW) swath mode. The winds are derived using a consistent geophysical model function (gmf), CMOD5N, and variational Bayesian inversion approach as proposed in Portabella et al. (2002) and Sentinel-1 Ocean wind (owi) algorithm definition document. The input SAR and model (ECMWF) data used in the inversion are sourced from owi level-2 product, and the resulting derived winds are approximately at 1km horizontal spatial resolution as in the source product but derived using a consistent gmf over time (unlike the source product). Wind speeds are also calibrated against Metop-A and B scatterometer wind database of Ribal and Young, 2020 (JTECH). The data represented by this record, are presented in delayed mode.Lineage
