EUMETSAT - Data Tailor Standalone Instance

Introduction

In the EUMETSAT section of the European Weather Cloud, there's now an instance equipped with the Data Tailor Standalone and EUMETSAT Data Access Client (EUMDAC) together, 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

Due to design of the software, only one linux user is able to use the software without additional 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.
Choose a NAME for the instance type and move to next step.
Insert at least the following inputs and click next:
- layout: make sure it is rocky-datatailor
- plan: select one with at least 16GB of RAM (e.g. eo2.xlarge)
- network: private
- security group: ssh
Once done, click Complete and the provisioning will start.
Look for the instance list (Provisioning → Instances) to check the status of the instance.
Once ready you will see the green Running sign below the instance as below:

Post-provisioning

SSH into your instance following the Remote Access to the VM documentation. Alternatively, you can also use the console on Morpheus from your instance (Provisioning → Instances → select your instance and go to the Console section)

Running the following commands you can verify if the installation was successful.

Check conda installation and epct-desktop environment

$ conda env list
# conda environments:
#
base                  *  /usr/local/miniconda
epct-desktop             /usr/local/miniconda/envs/epct-desktop

After confirming the installation, add conda environment to your shell and then restart it.

Integrate conda in your shell and restart 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 HRSEVIRI product (MSG3-SEVI-MSG15-0100-NA-20240613095742.896000000Z-NA.zip) is downloaded directly from the Data Store (using eumdac to be specific) and untouched. EUMDAC is included in the Data Tailor standalone instance. An example EUMDAC download command is:

$ eumdac download -c EO:EUM:DAT:MSG:HRSEVIRI --limit 1

Above command is downloading latest available product from HRSEVIRI collection.
