SWOT Level 1B Low-Rate Interferogram Data Product, Version D

Published by Jet Propulsion Laboratory;NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: September 02, 2026 at 12:33 AM | Dataset Last Updated: September 01, 2026
Interferograms for each of the 9 Doppler beams formed and spatially averaged (low rate) by the On Board Processor, corrected on the ground for phase biases (inherent to the processing applied on board). The geometry of the measurements is also reported for use in subsequent processing. Gridded; full swath for each half orbit. Available in netCDF-4 file format.
