+Tag name: cam6_3_127
+Originator(s): pel, jet
+Date: Sept 12, 2023
+One-line Summary: Option to turn on HB where CLUBB is not active
+Github PR URL: https://github.com/ESCOMP/CAM/pull/849
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+	- Free atmosphere Richardson number based mixing (using the free atmosphere
+	part of the Holtslag-Boville PBL scheme) for those layers where CLUBB is
+	not active (turned on in cam6 or cam_dev). Also helps stabilize less diffusive
+	dynamical cores. The issue for this PR is #846 and it will also address issue #772
+
+Describe any changes made to build system: NA
+
+Describe any changes made to the namelist:
+  - Introduced namelist variable do_hb_above_clubb. Default False unless using cam6 or cam_dev then
+	Holtslag-Boville PBL scheme will be used above CLUBB top)
+  - new namelist variable se_pgf_formulation to allow use of older pgf calculation to help with waccm regression errors
+	Can have an interger value of 1 or 2.
+           1: Exner version of pressure gradient force (PGF)
+           2: Traditional pressure gradient formulation (grad p)
+
+List any changes to the defaults for the boundary datasets: N/A
+  - New Boundary data for ERP and SMS WACCM runs - these runs require a spun up IC.
+    inputdata/atm/waccm/ic/FW2000.ne30pg3_ne30pg3_nlev70_c230906.nc

+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by:fvitt, pel, eaton, cacraig, jesse

+List all files added and what they do: N/A
