Python-based tidal prediction software for estimating ocean, load, solid Earth and pole tides

pyTMD

Python-based tidal prediction software for estimating ocean, load, solid Earth and pole tides

For more information: see the documentation at pytmd.readthedocs.io

Installation

From PyPI:

python3 -m pip install pyTMD

To include all optional dependencies:

python3 -m pip install pyTMD[all]

Using conda or mamba from conda-forge:

conda install -c conda-forge pytmd

mamba install -c conda-forge pytmd

Development version from GitHub:

python3 -m pip install git+https://github.com/pyTMD/pyTMD.git

Running with Pixi

Alternatively, you can use Pixi for a streamlined workspace environment:

1. Install Pixi following the installation instructions
2. Clone the project repository:

git clone https://github.com/pyTMD/pyTMD.git

3. Move into the pyTMD directory

cd pyTMD

4. Install dependencies and start JupyterLab:

pixi run start

This will automatically create the environment, install all dependencies, and launch JupyterLab in the notebooks directory.

Dependencies

• dateutil: powerful extensions to datetime
