pacesm/MagneticModel · GitHub

This repository contains various utilities related to Earth magnetic field modelling and spherical harmonics.

The repository contains following directories:

• eoxmagmod - Collection models of the Earth magnetic field - python module
• qdipole - Quasi-Dipole apex coordinates evaluation - Fortran code compiled as a shared library (dependency of the eoxmagmod package)
• libcdf - CDF library source installation (dependency of the eoxmagmod package)

$ cd libcdf/
$ make build
$ sudo make install

By default, the library gets installed in /usr/local/cdf directory. To install it to a different path override the INSTALLDIR variable:

$ make install INSTALLDIR=<install directory>

$ cd qdipole/
$ ./configure
$ make build
$ sudo make install

Requires QDIPOLE, CDF libraries + NumPy and SpacePy Python packages to be installed. NumPy and SpacePy can be installed using pip.

$ cd eoxmagmod/
$ python ./setup.py build
$ sudo python ./setup.py install

The package contains the conda-build scripts allowing local conda build and installation following this procedure:

1. build the binary dependencies:

conda install conda-build
conda build ./qdipole
conda build ./libcdf
conda build purge

Tested on GNU/Linux. Possibly works on other POSIX systems. Does not work on MS Windows (primarily because of a missing Fortran compiler).

2. install the eoxmagmod in your conda environment:

conda activate <target-environment>
conda install numpy scipy matplotlib h5py networkx
conda install --use-local qdipole cdf
pip install spacepy
pip install ./eoxmagmod
