The Sentinel-3 Surface Topography Mission (STM) is a key component of the Copernicus Sentinel-3 mission, set to revolutionise operational oceanography with a suite of advanced surface topography data products over ocean and sea-ice. In addition the STM will collect data over all earth surfaces providing improved monitoring of River and Lake stage heights and inputs to the development of Digital Elevation Models.

Sentinel-3 will be the first Earth Observation mission to provide 100% SAR altimetry coverage and LRM mode will be maintained as a backup-operating mode. In order to fully exploit the SAR capability, and validating the algorithms evolution, lower level data products (L1A, L1B and L1B-S) will be made available to the users, in addition to the level 2 products.

The processing algorithms developed for the Sentinel-3 Topography mission have been selected to meet the operational objectives of the Copernicus program and do benefit from 20 years of Altimetry experience gained with the ERS, Envisat, T/P, Jason & Cryosat missions. On top of the heritage processing algorithms, the S-3 Topography processing baseline includes more recent processing algorithm such as the SAMOSA SAR Ocean Retracker.

This paper provides an overview of the S-3 STM data products that will be generated operationally within the Sentinel-3 Payload Data Ground Segment (PDGS) by the Instrument Processing Facilities (IPFs), as well as an overview of the Sentinel-3 STM processing algorithms baseline.
