Short summary
In this work we summarize 15 years of research and developments of short-lived halogens (SLH) using the Community Earth System Model (CESM) and present a complete description of the implementation and capabilities achieved with the latest version v2. The CESM2-SLH release includes specific namelist options, input files and technical notes detailing the most important SLH updates that must be considered for the different model configurations and resolutions.
