eo-tides: Tide modelling tools for large-scale satellite earth observation analysis
- âī¸ Github repository: https://github.com/GeoscienceAustralia/eo-tides/
- đĻ PyPI: https://pypi.org/project/eo-tides/

- đ° Paper: https://doi.org/10.21105/joss.07786
eo-tides provides powerful parallelized tools for integrating satellite Earth observation data with tide modelling. đ ī¸đđ°ī¸
eo-tides combines advanced tide modelling functionality from the pyTMD package with pandas, xarray and odc-geo, providing a suite of flexible tools for efficient analysis of coastal and ocean Earth observation data â from regional, continental, to global scale.
These tools can be applied to petabytes of freely available satellite data (e.g. from Digital Earth Australia or Microsoft Planetary Computer) loaded via Open Data Cube's odc-stac or datacube packages, supporting coastal and ocean earth observation analysis for any time period or location globally.

Highlights
- đ Model tide heights and phases (e.g. high, low, ebb, flow) from multiple global ocean tide models in parallel, and return a
pandas.DataFramefor further analysis - đ°ī¸ "Tag" satellite data with tide heights based on the exact moment of image acquisition
- đ Model tides for every individual satellite pixel through time, producing three-dimensional "tide height"
xarray-format datacubes that can be integrated with satellite data - đ Calculate statistics describing local tide dynamics, as well as biases caused by interactions between tidal processes and satellite orbits
- đ ī¸ Validate modelled tides using measured sea levels from coastal tide gauges (e.g. GESLA Global Extreme Sea Level Analysis)
Supported tide models
eo-tides supports all ocean tide models supported by pyTMD. These include:
- Empirical Ocean Tide model (EOT20)
- Finite Element Solution tide models (FES2022, FES2014, FES2012)
- TOPEX/POSEIDON global tide models (TPXO10, TPXO9, TPXO8)
- Global Ocean Tide models (GOT5.6, GOT5.5, GOT4.10, GOT4.8, GOT4.7)
- Hamburg direct data Assimilation Methods for Tides models (HAMTIDE11)
- Technical University of Denmark tide models (DTU23)
For instructions on how to set up these models for use in eo-tides, refer to Setting up tide models.
Installing and setting up eo-tides
To get started with eo-tides, follow the Installation and Setting up tide models guides.
Jupyter Notebooks code examples
Interactive Jupyter Notebook usage examples and more complex coastal EO case studies can be found in the docs/notebooks/ directory, or rendered in the documentation here.
