stereoid 0.4

The stereoid tools for the Harmony mission.

Stereoid packages together a set of software tools that are used in the design and analysis of the Harmony satellite mission.

Setting up your development environment to run stereoid

To be able to run the Jupyter Notebooks and use the modules defined in the library you will need to install a few dependencies. Setting up a virtual environment and running “pip install .” should automatically fetch and install the necessary packages. Detailed instructions on how to do so follow:

You will need a recent version of Python installed on your system. We suggest 3.9 or later but 3.8 is also know to work. Once you have Python, you can create a virtual environment so that you can install packages in isolation. You can do this by running the following command on Unix/macOS:

python3 -m venv drama-env

or on Windows:

py -m venv drama-env

This will create a folder called “drama-env” in the folder where the previous command was ran. All packages will be installed in this folder. Now to activate this environment run this on Unix/macOS:

source drama-env/bin/activate

or on Windows:

.\drama-env\Scripts\activate

Now change to the directory where you have downloaded the stereoid package to and execute: git switch develop pip install -e .

The first command switches to the develop branch and the second installs the package. Make sure that “pip install -e .” is ran from the root level of the git repository, ie from the directory where the setup.py and README.rst files are.

After this you can install Jupyter Lab (if you don’t already have it) and start running the Jupyter Notebooks.

Running the Harmony scientific workbench

The package provides a cli program that sets up a simulation scenario, reads the wave spectra from the SWAN model and runs the ocean scientific workbench for the Harmony mission. To run, execute: harmulator_fwd [--debug] /path/to/params_scientific_workbench.py The –debug flag provides additional information in the console log. A sample params_scientific_workbench.py is provided in the PAR directory of this repository.
