+One-line Summary: Fixes for failing restart tests
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1289
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+     - Fixes failing cosp test which was writing out a task dependent cosp variable
+     - Always sets cam_out%netsw, not only when shortwave radiation call was made
+     - Two restart_test have answer changes due to moving mountain update in cam6_4_078:
+         https://github.com/ESCOMP/CAM/issues/1284 (turned out to not be due to the moving mountain update)
+
+Describe any changes made to build system: N/A

+Describe any changes made to the namelist: N/A
+
+List any changes to the defaults for the boundary datasets: N/A

+M       cime_config/testdefs/testmods_dirs/cam/outfrq3s_cosp/user_nl_cam
+          - Remove task dependent variable from cosp output file
+
+M       src/physics/rrtmgp/radiation.F90
+          - Always set cam_out%netsw
+
+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.
