SHTOOLS; Fortran/Python spherical harmonic transform software package

The current version of SHTOOLS is 3.3 (released August 11, 2016)

What is SHTOOLS?

SHTOOLS is an archive of Fortran 95 and Python software that can be used to perform spherical harmonic transforms and reconstructions, rotations of data expressed in spherical harmonics, and multitaper spectral analyses on the sphere.

SHTOOLS is extremely versatile:

How do I install SHTOOLS?

The most recent release of SHTOOLS can be downloaded from GitHub. To install the Python components, installation can be as simple as executing the following command in a unix terminal

pip install .

To install the fortran components, or to compile the Python components manually, use

make fortran
make fortran-mp (for OpenMP)
make python2
make python3

Full installation instructions can be found here, and additional information can be found on the GitHub wiki. You can keep up to date by following SHTOOLS on Twitter.

How do I use SHTOOLS?

SHTOOLS can be invoked in any Fortran 95, Python 2, or Python 3 program. The base SHTOOLS software is written in Fortran 95, and Python wrappers allow simple access to all fortran-compiled routines. A variety of Python notebooks and example files are included that demonstrate the major features of the library.

SHTOOLS is open source (revised BSD license) and makes use of the freely available Fourier transform package FFTW and the linear algebra packages LAPACK and BLAS.
