Data access

CYMS provides with Sentinel-1-derived ocean surface wind field products acquired along Tropical Cyclone forecast tracks through a single integrated portal. It also provides data over polar lows and extratropical cyclones.

  • Ocean surface wind estimates day and night at high spatial resolution and over wide images for hurricane-force winds, additional key information on Tropical Cyclone structure: maximum wind speed, eye diameter, wind radii, eyewall replacement cycle… from Sentinel-1,
  • complementary existing observations (geostationary imagery, radiometry ) for a full overview,
  • Customized, validated and fully acknowledged products,
  • Standardized, interoperable and harmonized service,
  • WebGIS platform and archive center,
  • Near real-time information
