WMM2020 World Magnetic Model...in simple, object-oriented Python. Tested on Linux, Mac and Windows. Most C compilers work, including GCC, PGI and Intel compilers. At this time Visual Studio is not supported since MSVC doesn't export function symbols without additional headers, which is typically done with something like SWIG.

for the latest release from PyPi:

python -m pip install wmm2020

Optionally, to get the cutting-edge development version:

git clone https://github.com/space-physics/wmm2020

python -m pip install -e wmm2020

This Python wrapper of WMM2020 uses our build-on-run technique. The first time you use WMM2020, you will see messages from the Meson build system and your C compiler.

an example script

python RunWMM2020.py

or as a Python module:
