 One-line Summary: Improvements to moving mountains parameterization
-Github PR URL:
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1281
 
 Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+ - Updates to moving mountains scheme for tuning QBO in MT (same settings adopted for LT:  https://github.com/ESCOMP/CAM/issues/1276
+ - Turn off moving mountains for dycores not passing vorticity to physics: https://github.com/ESCOMP/CAM/issues/1270
+
+Describe any changes made to build system: N/A
+
+Describe any changes made to the namelist:
+  - use_gw_movmtn_pbl is set to false if it is not CAM7 and SE dycore
+  - change values for gw_qbo_hdepth_scaling and effgw_beres_dp for specific configurations
+
+List any changes to the defaults for the boundary datasets: N/A
+
+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by: cacraig
+
+List all files eliminated:
+
+List all files added and what they do:
+
+List all existing files that have been modified, and describe the changes:
+M       bld/build-namelist
+M       bld/namelist_files/namelist_defaults_cam.xml
+          - update namelist settings
+
+M       src/physics/cam/gw_convect.F90
+          - Limit value for hdepth
+
+M       src/physics/cam/gw_drag.F90
+          - Change the beres storm_shift setting
+
+
+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.
+
+derecho/intel/aux_cam:
 
-Updates to moving mountains scheme for tuning QBO in MT (same settings adopted for LT; issue 1276).
-Turn off moving mountains for dycores not passing vorticity to physics (1270).
+derecho/nvhpc/aux_cam:
+
+izumi/nag/aux_cam:
 
-Resolves #1276 - tune QBO in MT.
+izumi/gnu/aux_cam:
 
-Resolves #1270 - Crash when running moving mountains with FV dycore.
+CAM tag used for the baseline comparison tests if different than previous
+tag:
 
-Only SE dycore in LT and MT regression tests should be affected.
+Summarize any changes to answers, i.e.,
+- what code configurations:
+- what platforms/compilers:
+- nature of change (roundoff; larger than roundoff but same climate; new
+  climate):
 
+If bitwise differences were observed, how did you show they were no worse
+than roundoff?
+
+If this tag changes climate describe the run(s) done to evaluate the new
+climate in enough detail that it(they) could be reproduced, i.e.,
+- source tag (all code used must be in the repository):
+- platform/compilers:
+- configure commandline:
+- build-namelist command (or complete namelist):
+- MSS location of output:
+
+MSS location of control simulations used to validate new climate:
+
+URL for AMWG diagnostics output used to validate new climate:
