SWOT: Update to SWOT Version C KaRIn Science Data Products
The joint NASA/CNES SWOT project is pleased to announce that an update to the SWOT KaRIn Science Data processing algorithms is applied to the forward-processed Version C products for observations starting October 16, 2024.
The joint NASA/CNES SWOT project is pleased to announce that an update to the SWOT KaRIn Science Data processing algorithms is applied to the forward-processed Version C products for observations starting October 16, 2024.
These updated algorithms address several known issues in the original SWOT Version C KaRIn Science Data products.
Additional details about the update to the SWOT Version C KaRIn Science Data products can be found in the release note.
Note, in particular, that the product version identifier, or Composite Release Identifier (CRID), in the file names of KaRIn Science Data products should be used to distinguish Version C products with resolved issues from the original release.
The CRID for KaRIn version C products have values of:
- PGC0 for reprocessed version C products spanning March 30, 2023 to January 25, 2024 (repeat cycles 475-578 of calibration phase, and repeat cycles 1-9 of science phase). This reprocessing is now complete.
- PIC0 for forward-processed version C products spanning January 25, 2024 to October 15, 2024 (repeat cycle 10 to part of repeat cycle 22 of science phase).
- PIC2 for forward-processed version C products spanning October 16, 2024 (part of cycle 22 of science phase) onward.
The PIC2 products have resolved several algorithm and product issues that were identified in the PIC0/PGC0 products. There are no changes to the data access mechanisms for the Version C products.
