ERA5 Regular and Land Finalization Disjunct?


I work for a company which regularly prepares ETLs of ERA5 datasets. We have noticed a slight lag in the finalization of ERA5 Regular datasets — instead of finalizing through January 31st, 2023 on April 1st, they have continued to only be finalized through December 31st, 2022. Has there been a change in the approximate finalization schedule ECMWF tries to uphold?

Additionally, we have noticed that ERA5 Land datasets are only finalized through November 30, 2022. Is there a reason for the 1 month lag on these datasets and should we anticipate that this is a normal occurrence going forward?

Many thanks,
