Python/Fortran 90 package to solve the passive and active microwave radiative transfer in a plan parallel horizontally homogeneous atmosphere with hydrometeors

Manual and Installation

Recommended, for Linux (x86_64) and macOS (Apple Silicon / arm64):

pip install pamtra

(If you previously used the old make pyinstall workflow, see the installation docs below for a warning about removing its leftover ~/lib/python/pyPamtra by hand -- it can silently shadow this.)

Not available as a wheel for Windows or Intel macOS -- see https://pamtra.readthedocs.io/en/latest/installation.html for those and other install options (conda-forge/pixi, building from source, HPC clusters).
