This dataset contains 10m neutral stability wind speed and direction derived from Sentinel-1 A, B and C 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). This data has also been combined and interpolated to a nominal 0.01 x 0.01-degree regular grid (available as a separate gridded product: IMOS - Satellite Remote Sensing - Surface Waves Sub-Facility - Gridded SAR wind - Delayed mode data). The data represented by this record, are presented in delayed mode.
