SWOT Postlaunch Oceanography Field Campaign L1 Moorings

Published by NASA/JPL/PODAAC | National Aeronautics and Space Administration | Metadata Last Checked: January 17, 2026 | Last Modified: 2026-01-13
The SWOT Postlaunch Oceanography Field Campaign L1 Moorings collection provides the surface air pressure, GPS, and conductivity, temperature and depth (CTD) measurements from moorings at the L1 processing level. The SWOT satellite mission launched in late 2022 and underwent a calibration and validation (cal/val) phase in 2023. As part of cal/val, an array of oceanographic instruments was deployed at a site 300 km offshore of California, including moorings at 11 distinct sites from February to October 2023. L1 data are instrument data converted to physical units and merged with the relevant metadata. L1 data do not have adjustments to calibrations or scientific quality control applied. L1 data are meant for data provenance only, and are likely only to be useful to users involved in calibration issues.
