It was noted that we have several AOP Epics about diagnostics (SOCA, OBS, JEDI projects) plus we have a number of JCSDA github repositories (ioda-plots, fsoi, plotting_diagnostics, DAdiagnostics) dedicated to diagnostics. It was agreed that the AOP Epics and repositories need to be consolidated. Yannick set the goal of converging to one repository and suggested the creation of a focused group to work toward this goal.  There was also some discussion of which plotting/diagnostics tools/repos, if any, should be included in the release.

Chris S asked the group for a list of what was missing from the diagnostics systems presented and discussed today. We heard details about what the RUC group is doing from Ming and what EMC is doing from Rahul. Points that were made include plotting long term bias and make sure to preserve the O-minus-F from runs as they progress (since O-minus-F is used by several groups for diagnostics). Tom summarized nicely by describing a 3-tiered approach to diagnostics:
