This paper thoroughly describes the data processing steps and assessment of the usefulness of the new SWOT mission for advancing ocean science. The paper will be of great interest the ocean and sea ice communities and others. The discussion of the benefits, relevance, and limitations of Level-3 swath-altimeter products for various research domains is particularly important.

Short summary
The Surface Water and Ocean Topography (SWOT) mission delivers unprecedented swath-altimetry products. In this paper, we describe how we extended the Level-3 algorithms to handle SWOT’s unique swath-altimeter data. We also illustrate and discuss the benefits, relevance, and limitations of Level-3 swath-altimeter products for various research domains.
