We are hereby informing users of the Essential climate variables for assessment of climate variability from 1979 to present dataset, that access to the ERA-interim data source is discontinued, as of today 1st May 2026. This is because a few years ago, ERA-interim was replaced by ERA5 in the production of the monthly bulletins, making its availability as part of the Essential climate variables for assessment of climate variability from 1979 to present dataset redundant.
Meanwhile a new feature has been added to the Essential climate variables for assessment of climate variability from 1979 to present dataset whereby users may now also request the data (ERA5 and ERA5-Land sources only) in the NetCDF4 file format.
The dataset documentation has been updated to reflect the changes presented above.
