We are glad to inform CryoSat data users that the new Ocean Baseline D processors are operational and associated products are now available on the Science Server.

Ocean Baseline-D product generation began on 30 September 2024 and provides significant improvements to the CryoSat Ocean products. This includes an update to the SAMOSA retracker version (2.3 to 2.5), dedicated processing for Sea State Bias in SAR mode and revised mean sea surface (MSS) and Mean Dynamic Topography (MDT) solutions.

More details about the changes implemented in the Baseline-D upgrade can be found in the Baseline D Evolution document. In addition, general information about the Baseline-D Ocean Processors is available in the updated Product Handbook and Product Format Specification.

CryoSat data processed using Baseline-D is now available on the Science Server. To make room for Baseline-D products, the old Ocean_Baseline_B directory has been removed from the CryoSat Science Server and all Ocean Baseline-C products have been moved to the Ocean_Baseline_C directory.
