Editorial interest 82/100 Selection signal · not a rating of the site

An interactive viewer for exploring SWOT satellite measurements of sea-surface height by region and time.

Landing page captured for the 2026-10-31 issue.

For: Oceanographers and researchers exploring SWOT sea-surface data
Worth noticing: The entire mission is stored in passage-sized IceChunk chunks, so regional reads fetch only the chunks that cross the selected area.

Field notes

The page says the source AVISO files are combined into one IceChunk store, with descending passes reoriented south to north and per-pass geometry added. Its timing examples report a Gulf Stream 2°×2° three-week subset in 2.7 seconds, compared with 17 seconds from AVISO, while a whole-mission subset is reported at 7.4 seconds versus 654 seconds.
