I'm using cesm2.2.1-rc.01 (CAM tag cam_cesm2_2_rel_07) for a study that depends on the distribution of marine low cloud, particularly subtropical stratocumulus. My analysis regions were originally derived from CESM2.1 output, and I'm trying to work out whether they're still appropriate for CESM2.2. Are there known differences in marine low cloud between the CESM2.1.z and CESM2.2 series? The release notes mention "answer-changing developments," but the CAM6.3 changes appear centered on dynamical cores and I haven't found anything specific to CLUBB or low cloud. Relatedly, does any free-running CESM2.2 output at f09 exist publicly, ideally with COSP enabled?
