SWOT Pixel Cloud

The SWOT Level-2 HR Pixel Cloud dataset provides points cloud of water mask pixels (“pixel cloud”) from the High Rate data stream of the SWOT KaRIn instrument with geolocated heights, classification mask, geophysical fields, and flags at 20 meter resolution on average.

The dataset was generated by the SWOT Mission Center but may be simulated using the SWOT Hydrology Toolbox Open Source tools.

The SWOT Level-2 HR Pixel Cloud dataset is organized into swath-aligned tiles. Each of these tiles nominally contains data over 64 km x 64 km.

Major SWOT product versions are called “baseline”. Currently, on our platform, you can download and manipulate products from both baseline C and D. Baseline C covers the period from March 28, 2023 to May 05, 2025. After this date, only baseline D products are available. A global reprocessing is on-going to produce baseline D products for the full SWOT activity period. Baseline D products are progressively made available so you might find some gap in baseline D until the end of the reprocessing.

General, global and up-to-date information on SWOT products can be find in the SWOT User Handbook. For a focus on how to distinguish between Baseline C and D products along with most significant changes in products, please refer to the Version D Release Note and the Major Changes from Version C to D slides.
