We are happy to announce the release of version vDT2021 of the following satellite-based dataset in the Climate Data Store:
Sea level daily gridded data from satellite observations for the global ocean from 1993 to present
This new version supersedes the current version , whose production will end in early October 2021.
The new version includes the following improvements:
- 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)
- Start 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 can be found in the dataset documentation.
Users retrieving the data using 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.
import cdsapi
c = cdsapi.Client()
c.retrieve(
'satellite-sea-level-global',
{
'version': 'vDT2021',
'variable': 'all',
'format': 'zip',
'day': '01',
'month': '01',
'year': '2020',
},
'download.zip')
The regional Sea level daily gridded data from satellite observations for the Mediterranean Sea from 1993 to 2020 and Sea level daily gridded data from satellite observations for the Black Sea from 1993 to 2020 datasets are however no longer updated and ends on 6 June 2020.
