- We are happy to inform our users that the implementation of the new IFS cycle happened successfully, starting with the 06 UTC run of the Boundary Conditions Optional Programme on . See News release.
- We have re-opened the dissemination requirements interface on at 08:00 UTC.
- Users can request the new model output parameters listed below from the dissemination system.
- We would like to thank all our users for their testing the new IFS Cycle 46r1 data and products during the release candidate phase.
- Please do not hesitate to contact our Service Desk if you experience any problem after the implementation of the new IFS Cycle 46r1.
- We inform our users of the dissemination system that we will freeze the requirements interface on Monday at 09:30 UTC for 2 days, in preparation of the implementation of the new IFS Cycle 46r1. No requirements changes will be allowed during this period. We apologise for any inconvenience caused.
