SWOT Level 1B Low-Rate Interferogram Data Product, Version 1.1

(SWOT_L1B_LR_INTF_1.1)
DOI10.5067/SWOT-INTF-1.1
Short NameSWOT_L1B_LR_INTF_1.1
DescriptionInterferograms 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.
Version1.1
Dataset TypeDEPRECATED
