Hello!
I use “ERA5 hourly data on single levels from 1940 to the present” for my research. The accuracy and level of detail of the ERA5 data are excellent and fully meet my requirements.
However, I need to obtain data for “day −4” relative to the current date (for example, for December 13, 2025, if today is December 17, 2025). The dataset I am currently using does not include such data. What alternative datasets are available that can provide comparable accuracy for “day −4”?
