WMM2025

WMM2025 World Magnetic Model...in simple, object-oriented Python. Tested on Linux, Mac and Windows. Most C compilers work. 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.

Install

for the latest release from PyPi:

python -m pip install wmm2025

Optionally, to get the cutting-edge development version:

git clone https://github.com/Navigraph/wmm2025

python -m pip install -e wmm2025

This Python wrapper of WMM2025 uses our build-on-run technique. The first time you use WMM2025, you will see messages from the Meson build system and your C compiler.

Usage

an example script

python RunWMM2025.py

or as a Python module:

import wmm2025

mag = wmm2025.wmm(glat, glon, alt_km, yeardec)
