An archive of wind fields retrieved from satellite Synthetic Aperture Radar (SAR) observations over the ocean by the Technical University of Denmark (DTU, The wind fields are instantaneous ocean backscatter measurements converted to ocean winds at 10m above the sea surface, through the implementation of dedicated retrieval algorithms and input wind directions from numerical models. The archive is updated daily and users can browse and download the wind fields though a web interface. The maps are available in .nc and .png format.

The archive of wind fields is generated with the SAR Ocean Products System (SAROPS) developed by the Johns Hopkins University, Applied Physics Laboratory (JHU/APL, and the US National Atmospheric and Oceanographic Administration (NOAA, The system uses input data from the following sources:

1 Wessel, P., and W. H. F. Smith, 1996. A Global Self-consistent, Hierarchical, High-resolution Shoreline Database, J. Geophys. Res., 101, 8741-8743.
