SWOT Level-2 HR Lake Single Pass - Unassigned

The SWOT Level-2 HR Lake Single Pass - Unassigned dataset provides vectorized lake data - including water surface elevation, water surface area, and derived storage change - from the High Resolution data stream of the SWOT KaRIn instrument, along with appropriate uncertainties and flags.

This dataset is observation-oriented and complementary to the SWOT Level-2 HR Lake Single Pass - Observed dataset. It contains one record for each observed water bodies, greater than 1ha, that have not been priorly identified in the SWOT Prior Lake Database (PLD), and are covered by the granule. The SWOT Level-2 HR Lake Single Pass - Observed dataset contains the water bodies that were priorly identified in the PLD.

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 Lake Single Pass - Unassigned dataset is provided in full-swath pass granules covering individual continents. Note: a granule covers a swath that is approximately 128 km wide in cross track. Although SWOT performance requirements are only applicable from 10–60 km from nadir on each side; observations may be missing, degraded, and/or flagged over the central 20 km of the swath. A pass is a half revolution of the Earth by the satellite from pole to pole.
