An issue has been identified with the ERA5 daily statistics catalogue entries which effected requests for non-consecutive dates for non UTC-00:00 time zones (note that for accumulated variables, time-zones are offset by -1 hour). Requests submitted before 12/02/2025, for non-consecutive date ranges for non-UTC time-zones may contain under-sampled data points for the dates before and after the gap in the date range. For example, a request with {‘day’ = [‘01’, ‘02’, ‘09’, '10], ‘time-zone’: ‘UTC-03:00’}, the data for the ‘02’ will be under-sampled, the file will also contain data for the ‘08’ which is also an under-sampled aggregation.
The issue has been addressed and users should re-request any data where they have requested non-consecutive date ranges for time-zone which are not ‘UTC+00:00’.
