Date of report: June 2024
Title: CLUBB conversion from wet to dry mixing ratios
Issue: CLUBB (Cloud Layers Unified By Binormals) is a sub-gridscale parameterization of clouds and turbulence. It includes a conversion from wet to dry mixing ratios, that was incorrectly set to "double dry", and wet tracers were not converted to dry.
Model tags affected: The issue was committed in tag cam6_3_094 and remained later versions.
Model response: Impacts on stratospheric water vapor and potential influence on the "tape recorder".
Fix: Correct code in clubb_intr.F90.
