NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) released “Beta Pre-Validated” Surface Water and Ocean Topography (SWOT) Ka-band Radar Interferometer (KaRIn) Science Data Products. The primary purpose of this release is to familiarize users with science data products from in-flight KaRIn data. This release includes:

  • Reprocessed global low rate (LR) ocean products spanning March 30-July 10, 2023 from the calibration phase (1-day orbit).
  • Forward processed global low rate (LR) ocean products spanning Sept. 7-Nov. 21, 2023 onward from the science phase (21-day orbit), using consistent software and calibrations as used for the reprocessed data.
  • Reprocessed global high rate (HR) hydrology products spanning April 8-22, 2023 from the calibration phase (1-day orbit).

Please refer to the official release note for a more comprehensive description of the data coverage for each product in this release. Additionally, data users are encouraged to consult the Product Description Documents (PDDs) for detailed explanations of data product content and format. The PDDs can be accessed from the dataset landing page for each product listed below.
