The EUMETSAT Data Store

The EUMETSAT Data Store is the primary online data access mechanism for all data from missions operated by EUMETSAT (including mandatory missions and the Copernicus programme). In operations since 2021, collections are gradually being added so that eventually the vast majority of data will be available online for immediate access. The Data Store has a graphical user interface that is integrated with the EUMETSAT product navigator catalogue, allowing users to explore the data available. Users can search the catalogue and filter using various criteria including things like the mission/instrument the data comes from (if you already know this), but also based on parameters of interest (e.g. Chlorophyll-a, SST, significant wave height).

Behind the GUI are a series of Application Programming Interfaces (APIs) which allow users to access larger batches of data and/or access data routinely using programming tools. EUMETSAT provides a data access client (EUMDAC) which wraps around the APIs to simplify access for users.

The Data Store is an excellent option for those wishing to access data online, either for a few images or for more advanced routine access.

In order to use the EUMETSAT Data Store, you should create a user profile and log-in using the button on the top right. To create an account, please visit the EUMETSAT Earth Observation Portal and create an account. These credentials also apply to EUMETView and EUMETSAT Data Centre, as well as to eumdac (see below).

The video below will walk you through the basic functionalities of the Data Store. For more detailed information, you can also consult the EUMETSAT knowledge base.

Automating EUMETSAT Data Store downloads with the EUMETSAT Data Access Client (eumdac)

The EUMETSAT Data Store is underpinned by a series of application programming interfaces (APIs) that support programmatic searching and access to Copernicus marine data. The architecture of these APIs can be quite complex, so to support users, we have developed the Python-based eumdac package, which unifies many common tasks under into a single, simple to use interface. Eumdac is available as both a command-line tool and Python library. We will use eumdac throughout our in-person training session, leading you through various of it's use. However, if you wish to get started with eumdac beforehand, you can find more information on the client, and the APIs it support here:

Examples of eumdac in use can be found throughout out Python-based learning materials.
