Pre-compiled binaries

Pre-compiled binaries of the ARTS interface for macOS and Linux including the ARTS engine for performing RT simulations can be installed from the conda-forge environment at the rttools channel:

conda install -c rttools pyarts

Other versions are available on the ARTS homepage.

ARTS depends heavily on catalog data. It is recommended to call at the beginning of your Python scripts to download and cache the latest version of the arts-cat-data and arts-xml-data packages. Alternatively, you can download the matching catalog data manually from the Github release page.

Building from source

See top level at our github repository.

The API of ARTS is constantly being updated to suit our and our users future need. Do not expect code compatibility between any two patches.

We strongly recommend to use the latest version of ARTS from conda unless you want to help with the development.
