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:
- Install Pixi following the installation instructions
- Clone the project repository:
git clone https://github.com/pyTMD/pyTMD.git
- Move into the
pyTMDdirectory
cd pyTMD
- Install dependencies and start JupyterLab:
pixi run start
This will automatically create the environment, install all dependencies, and launch JupyterLab in the notebooks directory.

Credits
The Tidal Model Driver (TMD) Matlab Toolbox was developed by Laurie Padman, Lana Erofeeva and Susan Howard. An updated version of the TMD Matlab Toolbox (TMD3) was developed by Chad Greene. The OSU Tidal Inversion Software (OTIS) and OSU Tidal Prediction Software (OTPS) were developed by Lana Erofeeva and Gary Egbert (copyright OSU, licensed for non-commercial use). The NASA Goddard Space Flight Center (GSFC) PREdict Tidal Heights (PERTH3) software was developed by Richard Ray and Remko Scharroo. An updated and more versatile version of the NASA GSFC tidal prediction software (PERTH5) was developed by Richard Ray. The pyFES prediction software was funded and supported by CNES and the FES model is distributed by AVISO.
