When does the ERA5T interim data get overwritten with the finalised ERA5 data? I read in a previous post that there is a 3 month delay, but I can see that currently (2025-08-05), data from 2025-03-31 has expver = 0001 (ERA5), and data from 2025-04-01 has expver=0005 (ERA5T).
I was expecting that the ERA5T data from April would have been overwritten with ERA5 by now?
I know that in general they are the same, but is there a schedule for when this happens?
