SWOT Level 2 Lake Single-Pass Vector Obs Data Product, Version D

Attributes also include uncertainties, flags for partial or dark water coverage, ice cover, and crossover calibration. Storage change estimates are reported in the PLD-oriented shapefile using both direct and incremental methods under different bathymetric assumptions. The LakeSP product provides consistent reach-scale and basin-level lake measurements suitable for time series analyses, hydrologic modeling, and integration with prior lake databases.

It enables monitoring of water level changes and surface area dynamics across a wide range of inland water bodies and supports hydrological applications in water balance studies, reservoir management, and climate impact assessment. This collection is a sub-collection of its parent: podaac.jpl.nasa.gov/dataset/SWOT_L2_HR_LakeSP_D It contains observation-oriented feature datasets of lakes identified in the prior lake database (PLD).
