Significant Wave Height

The Significant Wave Height (SWH) is the average wave height (from trough to crest) of the highest third (33.33%) of the waves in a given sample period.

The Sentinel-3 mission is able to monitor wave heights from 0 to 20 m.

The Sentinel-3 mission SWH goal accuracy is 4% (8 cm at 2 m SWH) for Near Real-Time (NRT) products and 1% (2 cm at 2 m SWH) for Slow Time Critical (STC products).

The marine sea state (SWH or Hs) product is a critical product for all maritime safety and rescue operations.
