Thin Python wrapper for the SCREEN3 point source dispersion model

Project description


Thin Python wrapper for the SCREEN3 point source dispersion model

CI workflow status

pdoc API documentation:



pip install screen3


pip install git+


The screen3 Python package does not include the SCREEN3 model itself. To download it (into ./src/), you can use (within Python):

import screen3

or on the command line:

python -c "import screen3;"


On Windows, the above (download only) is sufficient to be able to use screen3, since EPA provides an executable compiled for Windows.


On non-Windows platforms, the SCREEN3 model must be built from source. The function, which requires dos2unix, patch, and gfortran, can be used:

python -c "import screen3;"

or combined with the download:

python -c "import screen3;;"


To obtain the examples, git clone the repo, use Code > Download Zip (buttons), or use this DownGit link:
