We would like to inform you about upcoming infrastructure maintenance on part of the hosts on the EUMETSAT side of the European Weather Cloud (EWC). The maintenance will take place on 3 September 2025, from 15:00 to 18:00 UTC.

During this window, virtual machines (VMs) running on the affected hosts will be restarted. This will cause a short downtime for the affected VMs. Please ensure you save your work and prepare for a temporary service interruption during this period.

If you have any concerns regarding your workloads, or would like to know whether a specific VM is affected, please contact us at https://chat.europeanweather.cloud or raise a ticket at https://support.europeanweather.cloud 

We apologize for the inconvenience and thank you for your understanding!

Dear all,

We are excited to announce the pilot release of the Managed Kubernetes on the EUMETSAT side of EWC. 

This service allows tenants to create and manage their own Kubernetes clusters within their tenancy. The Kubernetes control plane is centrally managed by EWC administrators, while dedicated worker nodes are deployed inside each tenant’s environment — ensuring isolation, flexibility, and full control of application workloads. 

To request access to the service during the pilot phase, please raise an EWC support ticket. 

Documentation and setup instructions are available here.

🧪 Please note: This pilot is part of the validation phase of the Managed Kubernetes Service at EUMETSAT side. Users are encouraged to test the functionality and provide feedback. The cluster management is subject to change as part of the ongoing harmonization of EWC services.

We are pleased to announce the addition of ground-based lightning-observation data from the NORDLIS network, which covers Northern Europe and contain all observed cloud-to-ground and intra-cloud strikes.

The new lightning dataset provides:

• exact strike locations and timestamps (Parquet files)

• strike counts aggregated to the same grid as the OPERA and SEVIRI data

Full documentation is available at:

Good morning all,
We are experiencing issues with the EUMETSAT instance of Morpheus at the moment. We are working on the fix. (Your running VMs are not affected.)
Sorry for the inconvenience.

Dear all,

EUMETCast Terrestrial over AMT is being upgraded to support anycast addressing on the GEANT AMT Relays. A new anycast address is now available: 62.40.96.44

This upgrade ensures automatic routing to the nearest AMT Relay, improving reliability and simplifying multicast data distribution.

🔧 For Existing Stations

All existing users should update their AMT configuration to use the new anycast address *before the end of June*. After this date, individual AMT Relay IPs will be retired.

Please follow the update workflow provided here: https://confluence.ecmwf.int/display/EWCLOUDKB/How+to+update+startup+script+for+EUMETCast+Terrestrial+station+on+EWC

This workflow will replace the station’s startup script to support the new anycast configuration.

🔄 For New Stations After 14th May 2025

If you are setting up a new EUMETCast Terrestrial station using the VM available on Morpheus after 14th May 2025, no action is needed — the configuration is already up to date.

If you encounter any issues just contact us via our Support Portal or discussion platform.

EWC Team on EUMETSAT side

Dear all ,

On 26 May 2025 we plan to update EWC Rocketchat starting from 9:00 AM CEST. The process should take around 1h.

During the maintenance period, rocketchat could be not accessible or not available. All data will be saved before update.

We apologize for any inconvenience this may cause.

We’re excited to announce that HTC Batch Processing on EUMETSAT side of the EWC now supports Singularity containers!

What is Singularity?
Singularity is a widely-used container technology designed specifically for high-performance computing (HPC) and scientific workloads. Unlike traditional container platforms, Singularity focuses on portability, security, and seamless integration with existing HPC infrastructure — allowing users to package entire applications and environments into a single, portable image.

What does this mean for you?
You can now submit and run batch processing jobs to the batch processing system using your Singularity container images, alongside existing container options.
You can find more information and an example job for singularity here: EUMETSAT - HTC batch processing#SingularityjobinHTCondor

You can join the common pool of nodes deploying execute nodes that have docker and singularity available!

Dear all,
