An issue with the ERA5-Land monthly averaged data from 1950 to present dataset was identified in January 2024 on both CDS discs and MARS tapes.
It affects the following part of the dataset:
Product: Monthly averaged reanalysis
Time period: from September 2022 to February 2024
Area: Global
Variables: all accumulated variables (please refer to Table 3 in ERA5-Land documentation)
Incorrect data for period September 2022 to February 2024 is no longer available to download using the interactive CDS Download data form over the web, but remains accessible for the time being via CDS API or direct MARS access. **Incorrect data from September 2022 to February 2024 will not be replaced on CDS discs nor MARS tapes. Instead users can recover the same data using the product monthly averaged reanalysis by hour of day at 00:00.
A fix is planned to be implemented for ERA5-Land monthly averaged data stored on CDS discs in time for the release of the March 2024 monthly averaged data (i.e. from March 2024 onwards).
For reference, this issue has been recorded as a “Known issue" in the ERA5-Land: data documentation.
