The PO.DAAC is pleased to announce the release of datasets from the Sentinel-6 Michael Freilich/Jason CS radar altimeter mission, which aims to provide high-precision measurements of global sea-level that build upon the extensive record of observation from the previous Jason series altimetry missions.

Several datasets are available to users for the first time with this release:

  • High resolution Altimetry products (Level 1A, Level 1B and Level 2)
  • Low resolution Altimetry products - Level 1B and Level 2 in NTC timeliness
  • Advanced Microwave Radiometer - Level 2 products in NTC timeliness
  • GNSS-RO Precise Orbit Determination Tracking Data - Hourly

A full list of Sentinel-6 altimetry datasets released to date can be found in Earthdata Search: https://search.earthdata.nasa.gov/search?fi=Poseidon-4%20Radar%20Altimeter!AMR-C!AMR&fpj=Sentinel-6
