Baltic+ SEAL: gridded and along-track sea level height

The European Space Agency funded Baltic SEAL project has used the Baltic Sea as a testbed region toadvance capabilities in Coastal Altimetry. It has produced a suite of two Sea Surface Height (SSH) productsand two further ancillary datasets, derived from altimetry measurements across a range of altimetrymissions spanning from May 1995 to November 2020. These SSH products are provided at two levels.The first product consists of along-track datasets of Sea Surface Height (SSH) estimates. Each dataset isderived from a single path of an altimeter over the Baltic Sea region. In addition to the SSH value, flags areprovided to advise users of measurements whose quality may be degraded. The second product type consistsof gridded data products covering the Baltic Sea region at monthly temporal resolution. In addition to thealong-track and gridded products, two further added value products are available - a new mean sea surfacedataset for the Baltic Sea, as well as a sea level trend and annual cycle dataset. These are also provided aspart of the Baltic SEAL product suite.
