+One-line Summary: Phase 1 of rk_stratiform CCPPization; CCPPize cldfrc
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1271
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+- Closes #1267
+- Fixes #1274 for incorrect vertical dimension of `tphysbc_cmfmc` in snapshots
+- Partial completion of https://github.com/ESCOMP/CAM/issues/1267; most code has been moved to atmospheric_physics.
+
+Describe any changes made to build system: N/A
+
+Describe any changes made to the namelist:
+- build-namelist updated to add `rk_stratiform_tend` snapshot point
+
+List any changes to the defaults for the boundary datasets:
+
+Describe any substantial timing or memory changes:
+
+Code reviewed by: nusbaume, cacraig
+
+List all files eliminated:
+D       src/physics/cam/cldwat.F90
+D       src/physics/cam/pkg_cldoptics.F90
+  - moved to atmospheric_physics: prognostic_cloud_water CCPPized scheme
+  - moved to atmospheric_physics: cloud_optical_properties to-be-ccppized library; dechunkized
+
+List all files added and what they do: N/A
+
+List all existing files that have been modified, and describe the changes:

+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.
