Launched in November 2020, the Sentinel-6A Michael Freilich altimeter mission was designed to ensure the continuity of the Jason-3 measurements. The Poseidon-4 altimeter onboard of Sentinel-6A operates in the so-called ‘interleaved mode’. It allows the provision of Low Resolution (LR) mode measurement, as currently available on the Jason-3 mission, and High Resolution (HR) mode ensured by the Synthetic Aperture Radar (SAR) instrument, as currently available for the Sentinel-3 missions. This is the first time that the two measurement modes are available on collocated positions allowing a perfect comparison and a better understanding of possible errors affecting one or the other mode. The first year of Sentinel-6A measurement was done in formation flight, where Sentinel-6A and Jason-3 are acquiring data using the same ground track separated by a few seconds. This step allowed the calibration and validation of the Sentinel-6A measurements. 

 

On March 24th, the CEOS Ocean Surface Topography Virtual Constellation (OST-VC) members declared Sentinel-6MF as the new Reference Altimetry Mission. Sentinel-6MF joins all other altimetry L2P/L3 products, including Jason-3 and Sentinel-3A&B, enlarging the family of high quality products that are relevant for the oceanographic studies.

 

The L2P/L3 products are along-track and include:

  • Sea Level Anomalies
  • Significant Wave Height and Wind Speed
