You will require Jupyter Notebook to run this code. We recommend that you install the latest Anaconda Python distribution for your operating system. Anaconda Python distributions include Jupyter Notebook.

The simplest and best way to install these packages is via Git. Users can clone this repository by running the following commands from either their terminal (on Linux/OSx), or from the Anaconda prompt.

You can usually find your terminal in the start menu of most Linux distributions and in the Applications/Utilities folder on OSx. Alternatively, you should be able to find/open your Anaconda prompt from your start menu (or dock, or via running the Anaconda Navigator). Once you have opened a terminal/prompt, you should navigate to the directory where you want to put the code. Once you are in the correct directory, you should run the following command;

git clone --recurse-submodules --remote-submodules https://gitlab.eumetsat.int/eumetlab/oceans/ocean-training/applications/ocean-case-studies.git

This will make a local copy of all the relevant files.

Note: If you find that you are missing packages, you should check that you ran git clone with both the --recurse-submodules and --remote-submodules options.

Note: if you are using an older version of git, you may find that your submodules are empty. In this case, you need to remove the folder and re-run the line above with --recursive added to the end

This collection supports Python 3.9. Although many options are possible, the authors highly recommend that users install the appropriate Anaconda package for their operating system. In order to ensure that you have all the required dependencies, we recommend that you build a suitable Python environment, as discussed below.

Python allows users to create specific environments that suit their applications. This tutorials included in this collection require a number of non-standard packages - e.g. those that are not included by default in Anaconda. In this directory, users will find a environment.yaml file which can be used to construct an environment that will install all the required packages.

To construct the environment, you should open either terminal (Linux/OSx) or an Anaconda prompt window and navigate to repository folder you downloaded in the Installation section above. In this folder there is a file called environment.yml. This contains all the information we need to install the relevant packages.

To create the environment, run:

conda env create -f environment.yml

This will create a Python environment called cmts_ocean_case_studies. The environment won't be activated by default. To activate it, run:

conda activate cmts_ocean_case_studies

Now you are ready to go!

Note: remember that you may need to reactivate the environment in every new window instance

This module is based around a series of Jupyter Notebooks. These support high-level interactive learning by allowing us to combine code, text description and data visualisations. If you have not worked with Jupyter Notebooks before, please look at the Introduction to Python and Project Jupyter module to get a short introduction to their usage and benefits.

To to run Jupyter Notebook, open a terminal or Anaconda prompt and make sure you have activated the correct environment. Again, navigate to the repository folder.

Now you can run Jupyter using:

jupyter lab

This should open Jupyter Lab in a browser window. On occasion, Jupyter may not be able to open a window and will give you a URL to past in your browser. Please do so, if required.

Note: Jupyter Notebook is not able to find modules that are 'above' it in a directory tree, and you will unable to navigate to these. So make sure you run the line above from the correct directory!

Now you can run the notebooks! We recommend you start with the Index module.
