Altimetry Marine Products

In this section you can find out more details about the Copernicus Sentinel-3 Altimetry products.

The marine and land product services for Sentinel-3A and -3B are split between EUMETSAT and ESA, respectively. Users mainly interested in altimeter data over ocean areas will retrieve the data from EUMETSAT; users with a focus on land areas are directed to ESA's data archive. To facilitate the use at the boundary between both realms, an overlap is included.

Altimetry Marine/Land Mask

Since July 2020, with Product Baseline 2.68-MARINE, the L2 SRAL marine product processing contains an updated marine/land mask. This implies minor changes in the geographical coverage of the Marine L2 products, only related to the extension of the coverage from coastline to land; from 10 km to 25 km. The extension also applies to the big inland water bodies already included in the marine L2 products.

All L2 products generated before July 2020 have a coverage of 10 km in-land, see previous Marine/Land Mask.
