ERA5T historical series

Hello all,

I am looking for the historical series of ERA5T, to study the historical accuracy of the temporary values compared with the final ones. Are the ERA5T series available somewhere (and if yes, where can I find it ?), or is it deleted when ERA5 final series are published ?

Thank you for your help,


Hi Thibault,

The normal process is that the "ERA5T" data are simply relabeled as "ERA5" after they have been validated, without any further changes. Hence all the ERA5 data were originally "ERA5T" .

Hope that helps,


Very clear, thank you Kevin for your answer ! Just to have a general idea, how often did ERA5T data need changes historically ? And would you have in mind an order of magnitude of the modification when necessary ?
