Introduction
In the EUMETSAT section of the European Weather Cloud, there's now an instance equipped with the Data Tailor Standalone, which includes all the currently available plugins on a Rocky Linux system. Below, you'll find a guide that covers the provisioning, a minimal post-installation process, and usage instructions.
The Data Tailor is a product customization toolbox designed to enable users to tailor satellite data to their specific needs. It offers the ability to subset and aggregate data products across space and time, filter layers, generate quick looks, reproject data onto new coordinate reference systems, and reformat data into widely used Geographic Information System (GIS) formats such as netCDF and GeoTIFF, as well as image formats like JPEG and PNG. The Data Tailor can currently customize data from various satellite collections, including METOP, MSG, and Sentinel-3. There are two versions of the Data Tailor: the Data Tailor Web Service (DTWS) and the Data Tailor Standalone. The DTWS allows users to customize products in the EUMETSAT Data Store before downloading them. On the other hand, the Data Tailor Standalone is an application that can be installed on your machine, enabling you to customize downloaded products. Unlike the Data Tailor Web Services, which can be used with EUMDAC or via https://tailor.eumetsat.int, the standalone version is generally faster and does not have limitations such as maximum concurrent jobs or workspace size. For more information on capabilities of the Data Tailor, please refer to Data Tailor Standalone Guide on User Portal and for more information about the available products and customisations inside the Data Tailor, please go to Products and Customisations Available in the Data Tailor page.
Current limitations
- The two of the Data Tailor plugins, epct_plugin_umarf and epct_plugin_netcdf_generator, are currently not available, hence they're not installed as default. We will put these plugins back in the installation as soon as they become available again.
- Due to design of the software, only one linux user is able to use the software without additonal settings. When a user runs the application for the first time, various configuration files are created with permissions only editable by that user.
Installation
Provisioning
- Create the Data Tailor standalone instance by clicking on + ADD button on your Morpheus Dashboard.
- Search for Data Tailor Standalone, select it and click next.
- Confirm the layout. We recommend at least 16GB of ram in your instance for the application. Click next.
- Create the instance and confirm it's running.
Post-provisioning
SSH into your instance following the Remote Access to the VM documentation. You can also use the console on Morpheus.
$ conda env list # conda environments: # base * /usr/local/miniconda dt_3_3 /usr/local/miniconda/envs/dt_3_3
After confirming the installation, add conda environment to your shell.
$ conda init no change /usr/local/miniconda/condabin/conda no change /usr/local/miniconda/bin/conda no change /usr/local/miniconda/bin/conda-env no change /usr/local/miniconda/bin/activate no change /usr/local/miniconda/bin/deactivate no change /usr/local/miniconda/etc/profile.d/conda.sh no change /usr/local/miniconda/etc/fish/conf.d/conda.fish no change /usr/local/miniconda/shell/condabin/Conda.psm1 no change /usr/local/miniconda/shell/condabin/conda-hook.ps1 no change /usr/local/miniconda/lib/python3.11/site-packages/xontrib/conda.xsh no change /usr/local/miniconda/etc/profile.d/conda.csh modified /home/USERNAME/.bashrc ==> For changes to take effect, close and re-open your current shell. <==
After restarting your shell, you should be able to see that you're in base environment of conda.

The Data Tailor Standalone is ready to use. Whenever you want to use the application, just activate your conda environment with $ conda activate dt_3_3 and run your customisations.
Usage
The Data Tailor standalone has multiple ways of use including a web-app GUI (graphical user-interface), CLI (command line interface), a Python Library and within EUMDAC. For more information, please refer to: Data Tailor Standalone Guide. Below is a small example of using the application with CLI.
(base) $ conda activate dt_3_3
Run your customisation.
