SAR measurements of ocean wind and wave fields in hurricanes
Bibliographic record
Abstract
Spaceborne synthetic aperture radar (SAR) is still the only instrument providing directional information on surface wind and ocean waves on a global and continuous basis. From RADARSAT-1, many SAR images have been collected over the past years, which cover several hurricanes and allow investigation of the wind and wave fields under these extreme situations. A time-frame of 27 days of ERS-2 SAR wave mode data was processed, which covers several tropical cyclones in the Atlantic Ocean, of which Hurricane Edouard has been investigated in detail together with additional data available from scatterometers, buoys and weather centers. The wind fields and wave parameters are extracted from SAR imagery and compared to results of the numerical model output provided by the European Centre for Medium-Range Weather Forecast (ECMWF) and co-located ERS-2 scatterometer measurements. For each wave system, spectral parameters such as wavelength, wave propagation direction and wave age are calculated and compared to the numerical model output provided by ECMWF.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
