Installation

This package can be installed through pip <https://pip.pypa.io/en/latest/installing.html>__ which downloads the package from the python package repository Pypi <https://pypi.python.org/>__.

.. code-block:: bash

pip install pytesmo

Note that pytesmo>=0.17 will only work with numpy>=2.0 and python>=3.9. If you still require a version compatible with numpy v1, install pytesmo<0.17.

Compiled C extensions are available as wheels for Windows and Linux for python 3.9 to 3.12.

For other operating systems and/or python versions, it might be necessary to compile the binaries yourself. This should happen automatically, if you have a C compiler installed (e.g. GCC <https://gcc.gnu.org/>_ ).

.. code::

git clone https://github.com/TUW-GEO/pytesmo.git --recursive
cd pytesmo
mamba create -n pytesmo python=3.12 # or any supported python version
conda activate pytesmo
pip install -e .[testing]  # install source package
python setup.py build_ext --inplace --cythonize  # optional compile cython C extensions
pytest  # Run tests to check if everything works

• Data from the International Soil Moisture Network (ISMN) <https://github.com/TUW-GEO/ismn/>_ In case of the ISMN, two different formats are provided: An example of how to use the dataset in the pytesmo validation framework can be found in the "Examples" chapter.
  • Variables stored in separate files (CEOP formatted)
