Reminder of impacts of ECMWF's Data Handling System (DHS) move to Bologna
As work to move ECMWF's DHS to Bologna progresses, the dates when users of C3S seasonal forecast data might experience disruptions are approaching.
- Two short dry-run tests successfully completed in April have paved the way for another, longer reduced service period in the coming weeks, lasting for 5 to 7 days; this will then be followed by the 4-week-long reduced service period during the actual move of the DHS infrastructure. The official announcements about the dates of these interruptions can be found in this link. This information will be updated as the work progresses so it is highly recommended you "watch" that page (see "Watch" button in the top right corner of the page).
- The expected impacts on the C3S seasonal forecast datasets are as follows:
- Data available during both future reduced service periods: real-time forecasts with start dates after March 2022 from all providers and hindcast data from MetOffice system=601 (produced on-the-fly) with start dates from April.
- Availability of other data is NOT guaranteed.
- Please note this includes hindcast data relevant to the start dates around these periods of reduced service, from providers other than the MetOffice. The recommendation for users is to ensure they have downloaded all hindcast data they may need well in advance of the start of these periods of reduced service.

- As it happens every year, label "system" for the UK Met Office contribution to C3S seasonal forecast activity will be updated to a new value (system=601) starting from March 2022 real-time forecasts.
- Please note that due to the production of hindcasts "on-the-fly", the CDS keyword 'system' does not have the same behaviour as for the other contributors. More info in the section "Versioning of forecasting systems contributing to C3S" of the Description of the C3S seasonal multi-system page.

- An upgrade to MetOffice contribution (change of forecasting system version to GloSea5-GC2-LI) has been introduced from May 2019 nominal start date.
