An updated version of ARTS 2.6 is now available. It contains bug fixes, performance and QoL improvements. The parallelization of lookup table calculations has been vastly improved. The list of changes is available on the Github release page.

We recommend to install ARTS in Miniforge3 with mamba install -c rttools pyarts. Existing environments can be updated with mamba update -c rttools pyarts. Conda packages for Python 3.9 have been dropped with this version. Packages are available for Python 3.10, 3.11, 3.12 and 3.13.

A new JQSRT article about ARTS 2.6 is now available: Stefan Bühler et al, "The atmospheric radiative transfer simulator ARTS, version 2.6 — Deep python integration"
