Degraded SWOT data quality from July 31 to August 7

The following message has been forwarded to all registered PO.DAAC users on behalf of the SWOT Project Team.

Dear SWOT data users,

The quality of SWOT products (PIC0) from July 31 to August 7 was impacted by late arriving telemetry.

KaRIn LR products for this period have been reprocessed. Please use products with the highest product counter.
