SWOT Level 2 KaRIn Low Rate Sea Surface Height Data Product - Expert, Version 2.0
Listed in Open NASA
The SWOT Level 2 KaRIn Low Rate Sea Surface Height Expert Data Product from the Surface Water Ocean Topography (SWOT) mission provides global sea surface height and significant wave height observations derived from low rate (LR) measurements from the Ka-band Radar Interferometer (KaRIn).
Description
SWOT launched on December 16, 2022 from Vandenberg Air Force Base in California into a 1-day repeat orbit for the "calibration" or "fast-sampling" phase of the mission, which completed in early July 2023.
After the calibration phase, SWOT entered a 21-day repeat orbit in August 2023 to start the "science" phase of the mission, which is expected to continue through 2025. The L2 sea surface height data product is distributed in one netCDF-4 file per pass (half-orbit) covering the full KaRIn swath width, which spans 10-60km on each side of the nadir track. Sea surface height, sea surface height anomaly, wind speed, significant waveheight, and related parameters are provided on a geographically fixed, swath-aligned 2x2 km2 grid (Basic, Expert, Windwave).

The sea surface height data are also provided on a finer 250x250 m2 "native" grid with minimal smoothing applied (Unsmoothed). This collection is a sub-collection of its parent: podaac.jpl.nasa.gov/dataset/SWOT_L2_LR_SSH_2.0 It provides the "Expert" file from each L2 SSH product, which contain all related variables and is intended for expert users.
