New CryoSat Ice Baseline-E 2018 and 2019 reprocessed data – available now!

17 May 2023

We are pleased to inform the CryoSat scientific community that the reprocessed CryoSat Ice Baseline-E data for all of 2018 and 2019 has been published on the Science Server and is now available for download. 

Ice Baseline-E was installed into operations in September 2021, bringing significant improvements to the CryoSat ice products, including improved sea surface height anomaly (SSHA) interpolation, provision of an improved snow depth correction, improvements to land-ice retracking, and the addition of pseudo-LRM estimates to the L1B products. More details about the changes implemented in Baseline-E can be found in the Baseline E Evolution document. In addition, a previous inconsistency with the cycle numbers and relative orbit numbers has been resolved and these are now correctly provided in the product headers. 

The Ice Baseline-E Reprocessing campaign is currently underway to reprocess all CryoSat ice products from July 2010 - August 2021 with the latest Baseline-E software version to bring them in line with the operational products. The reprocessing activity is progressing fast and more data will be available soon. Data is being published incrementally as soon as quality checks are completed. Another announcement will be made when a full year of data is available.
