+One-line Summary: Updates to age of air tracers history output
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1198
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+
+ Changes to age of air output #1197
+ . Output age of air tracers mix ratios to history as soon as the tendencies are update,
+   before the tracers are transported in the time loop
+ . Rename history field 'AOAMF' as 'AOA1'
+
+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
+
+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       src/physics/cam/aoa_tracers.F90
+ - add outfld calls for AOA tracers
+ - rename 'AOAMF' as 'AOA1'
+
+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.
