SWOT Level 1B Low-Rate Interferogram Data Product, Version D
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/swot-intf-d
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).
Description
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.
