Note that data from version vDT2021 will be provided only for the global ocean domain. The two following regional sea level datasets covering the Black Sea and the Mediterranean Sea will not be updated to the new version and their data record will end on not be extended beyond 6 June 2020:
- Sea level daily gridded data from satellite observations for the Mediterranean Sea from 1993 to 2020
- Sea level daily gridded data from satellite observations for the Black Sea from 1993 to 2020
.
The new vDT2021 version includes the following improvements: [TO BE UPDATED]
- Use of the ERA5 Reanalysis as auxiliary data for atmospheric correction in the CDR
- Improved temperature-based correction scheme for sea ice classification in warm conditions
- Level-4 product (instead of Level-3 for version 1.0)
- New Level-2P altimeter standards
- Improved Level-3 mapping algorithm
- Improved characterisation of the error budgets of altimeter measurementsStart of the Climate Data Record (CDR) in October 1978 (instead of January 1979 for version 1.0)
Additional information about the dataset and the changes implemented in version 2.0 vDT2021 can be found in the dataset documentation.
Users retrieving the retrieving data using via the CDS API or from within the CDS Toolbox should be aware that they need to add a new 'version' attribute to their Python request as shown in the example below. See also the example code snippets at the bottom of the download data tab of the dataset.
