+  - Update emissions datasets: https://github.com/ESCOMP/CAM/issues/1432
+
+Describe any changes made to build system: N/A
+
+Describe any changes made to the namelist: Updated emission datasets for ne30 LT and MT runs
+
+List any changes to the defaults for the boundary datasets: N/A
+
+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by: Cecile, nusbaume
+
+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       bld/namelist_files/use_cases/1850_cam_lt.xml

+M       bld/namelist_files/use_cases/hist_cam_mt.xml
+         - update emission files for ne30 LT and MT compsets
+
+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.
