The European Community’s Seventh Framework Programme project SECTRONIC will provide information on safety and security to maritime infrastructures at a global scale. Focus of this paper is on two implemented algorithms that employ data from Synthetic Aperture Radar (SAR) sensors. The first algorithm retrieves wind direction directly from the SAR image using standard image processing techniques. Wind speed is estimated by the inversion of a geophysical model function (GMF), having wind direction estimates as an input. Operational implemetation of mentioned algorithms is described and an example of results is provided.

Nyckelord: met-ocean, sea state, safety, security, maritime infrastructure, wind retrieval, Local Gradient, CMOD5.
