Halocarbons contribute approximately 20% of the total anthropogenic instantaneous clear-sky forcing. We have implemented a new absorption model for them, based on HITRAN cross-section data, and use it to calculate forcing estimates:

We are pleased to announce that version 1.1.0 of the ARTS scattering database has been released. Database, technical report and readme document have been updated.
Today we're happy to announce the release of ARTS 2.4. Since the last release in 2014, development has carried on and many new features and improvements have found its way into ARTS. Below you find a list of the most important changes.
Links to source code and documentation can be found on the Getting ARTS page.
Updated atmlab and arts-xml-data packages are available as well.
Thanks to all of you who have been using ARTS in the past years for their science. We're looking forward to your feedback and contributions.
