As per previous years, we would like to inform users that the Product Requirements Editor (PREd) will enter a read-only mode from 18 December 2025 to 5 January 2026.
ECPDS will remain accessible to those with existing access, but host and destination changes will not be completed during the freeze period.
During this period, no new requests or modifications to data requirements, service agreements, hosts or destinations can be made.
We encourage users to submit required changes before the freeze with sufficient time for Data Support to assist you. We thank you for your patience during this busy period.
To support your planning, we have included a simple calendar reminder with the freeze dates. (PREd_Freeze_Announcement_2025-2026.ics)
ECMWF Data Support Team will also be limited in capacity between 18 December 2025 and 05 January 2026.
24/7 support for operational issues remains available, but please note that configuration changes will not be made during this period.
