EUMETSAT has established a new set of data access services that are bringing the full data catalogue online. General information can be found here: https://user.eumetsat.int/data-access.
In addition, some selected datasets can be accessed from EWC VMs from the EWC object storage. Please contact us, if you need additional data which is not provided in the Data Store, or you have special conditions for access.
Option 1: Using EUMETSAT data services
To avoid duplication, the information on how to use the new data services can be found on the following links:
- Getting started guide for EUMETSAT data services, explaining what service to use for what purpose
- EUMDAC - recommended tool for simplifying and automating downloads from the EUMETSAT Data Store
In the future, it may become possible to directly access the object storage behind the Data Store for applications that need very high throughput (e.g. mass data processing). Please contact us if you have tried the existing possibilities and believe you need this capability.
Option 2: Using EUMETSAT data buckets
Available EUMETSAT data buckets are listed below with the corresponding mount point in case of using ready workflow
EUMETSAT Data Buckets:
Bucket | Mount point | Time range |
---|---|---|
ascat.metop-abc.level-1b.native | /eumetsatdata/ascat | 2012-10-22T11:00:00Z - 2013-04-24T08:57:00Z |

seviri.meteosat-0-degree.level-15.native | /eumetsatdata/seviri | 2020 |
drought-and-vegetation.prototype-datacube.netcdf | /eumetsatdata/psdc |
Using the data directly from workloads
It is advisable to use the data directly from workloads (scripts / applications). Please consult e.g.
for more help.
Mounting the buckets using FUSE
For data access, you will need to provision your instance on the EUMETSAT cloud. You can follow the Provision a new instance - web Knowledge Base Article to get started.
Following describes how to mount EUMETSAT data buckets as FUSE mounts. The possibility to mount the buckets into as filesystem is provided to as convenience. Readers are advised to note that mounting buckets via FUSE will provide significantly worse performance than accessing the data directly from workloads, for example using python. Whenever possible, users are advised to use the buckets directly from the workloads.
Tenants having Morpheus account at EUMETSAT Morpheus, can mount the data buckets using ready workflow. This article describes how to run the workflow and how to mount the data manually. One can naturally use the same steps to any other buckets as well by modifying bucket name, service endpoint, credentials, and potentially project id.
Using the Workflow
- Go to instances and select the instance of interest
- Select Actions → Run Workflow
- Select Mount EUMETSAT databuckets from Workflow drop-down meny and click Execute. Command options are not needed.
You can then follow the workflow from the output or by going to Instance History tab. After the workflow is executed, you can access the data at /eumetsatdata.
Manual mount
Following steps are using ASCAT data as an example. Please modify the commands to mount any other bucket.
Make sure you have latest rclone installed
curl https://rclone.org/install.sh | sudo bash
Create mount directory, i.e. for ascat:
sudo mkdir -p /eumetsatdata/ascat && sudo chown -R $USER:$USER /eumetsatdata/ascat && chmod 755 /eumetsatdata/ascat
Put rclone like listed below config into a config file. For example, into
/etc/eum_bucket_creds (keys without brackets)
sudo sh -c "cat >>/etc/eum_bucket_creds <<-EOF [eumetsat-ascat] type = s3 provider = Ceph endpoint = https://s3.waw3-1.cloudferro.com EOF
Now you can already mount the data with command:
sudo rclone --config /etc/eum_bucket_creds mount --allow-other --daemon eumetsat-ascat:ascat.metop-abc.level-1b.native /eumetsatdata/ascat
Setting up a service
To have mount points available all the time and after reboots, one need to set up the service and add mount points into fstab.
Link rclone
sudo ln -s /usr/bin/rclone /sbin/mount.rclone
Create systemd service:, for example for ascat:
sudo sh -c "cat >>/etc/systemd/system/eum-data-ascat.service" <<-EOF [Unit] Description=Mount EUMETSAT data bucket ascat After=network-online.target [Mount] Type=rclone What=eumetsat-ascat:ascat.metop-abc.level-1b.native Where=/eumetsatdata/ascat Options=ro,allow_other,args2env,vfs-cache-mode=writes,config=/etc/eum_bucket_creds,cache-dir=/var/rclone,vfs-cache-max-size=512Mi,vfs-cache-poll-interval=30m' EOF
Add corresponding line into /etc/fstab:
echo "eumetsat-ascat:ascat.metop-abc.level-1b.native /eumetsatdata/ascat rclone ro,noauto,nofail,x-systemd.automount,args2env,allow_other,vfs_cache_mode=writes,config=/etc/eum_bucket_creds,cache_dir=/var/cache/rclone,vfs-cache-max-size=512Mi,vfs-cache-poll-interval=30m 0 0" | sudo tee -a /etc/fstab
Mount the folder:
sudo mount /eumetsatdata/ascat
Limitations
- Access to the archive is read-only.
- Only a limited subset of EUMETSAT data is available. Please contact us if you need something that is not currently there.
