miescat 0.2.1

Mie scattering calculation based on MIEV0

miescat - MIEV0 wrapper

Fortran and Python wrapper of the MIEV0 code to compute Mie scattering by Warren J. Wiscombe.

The original MIEV0 code has been retrieved from ftp://climate1.gsfc.nasa.gov/wiscombe/Single_Scatt/Homogen_Sphere/Exact_Mie/.

Fortran executable

The Fortran executable is named miescat. It computes the Mie scattering parameters and the Legendre moments starting from a real and imaginary part of the scattering frequency, a radius, and a wavelength. The output may be parsed as json with jq.

A Python simple wrapper script mieleg may be used to have more explicit command line argugments.

mieleg --m_real 1.3484 --m_img 0.001 --radius 1.0 --wavelength 0.41

Python package

The Python package is a wrapper around the Fortran executable and exposes a Python interface to compute Mie scattering. The execution is spawn as a subprocess that the resuting Mie coefficients and Legendre moments are returned as a Python dictionary.

The package installs a command-line entry point miescat. It exposes the compute_mie_scattering function and the Mie class.

The package is available on PyPI miescat.

pip install miescat
