+One-line Summary: Remove extraneous log messages
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1442
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+ Remove extraneous log messages from GEOS-Chem and RRTMGP
+ Add new MPAS 120 km L26 analytic ICs.
+
+Describe any changes made to build system: N/A
+
+Describe any changes made to the namelist:
+ M bld/namelist_files/namelist_defaults_cam.xml
+ - Add new MPAS 120km L26 analystic ics
+
+List any changes to the defaults for the boundary datasets: N/A
+
+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by: cacraigucar
+
+List all files eliminated: N/A
+
+List all files added and what they do: N/A
+
+List all existing files that have been modified, and describe the changes:
+ M .gitmodules
+ M src/atmos_phys/
+ M src/physics/rrtmgp/radiation.F90
+ - update atmospheric physics tag and rrtmgp_inputs_run interface to remove RRTMGP messages
+
+ M src/chemistry/geoschem/chemistry.F90
+ - remove extraneous geoschem messages
+
+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.

+ - timing issue - Jian has determined this is due to changes on derecho with the the last upgrade. He has
+ reported the issue to CISL. Note cam6_4_128 is the last CAM tag with baselines to use for comparison
+ but answer changes are expected starting with cam6_4_130
