+Tag name: ctsm5.3.064
+Originator(s): slevis (Samuel Levis)
+Date: Wed Jul 23 11:51:50 MDT 2025
+One-line Summary: Add time dimension to 1d_wt fields in transient runs
+
+Purpose and description of changes
+----------------------------------
+
+ 1d_wt fields (e.g. pfts1d_wtgcell) appear in history when hist_dov2xy = .false.
+ This PR:
+ - adds the time dimension to these variables in Hist runs because these variables change with time
+ - adds new namelist variable vars_1dwt_w_time to let users add the time dimension when it is not added by default, i.e. in non-transient runs
+ - throws a build namelist error when the new namelist variable is .false. in a transient simulation
+
+Significant changes to scientifically-supported configurations
+--------------------------------------------------------------
+
+Does this tag change answers significantly for any of the following physics configurations?
+(Details of any changes will be given in the "Answer changes" section below.)
+
+    [Put an [X] in the box for any configuration with significant answer changes.]

+
+
+Bugs fixed
+----------
+List of CTSM issues fixed (include CTSM Issue # and description) [one per line]:
+ Resolves #3307 Updating vector history file output...
+
+Notes of particular relevance for users
+---------------------------------------
+Changes to CTSM's user interface (e.g., new/renamed XML or namelist variables):
+ New namelist variable vars_1dwt_w_time
+
+Changes made to namelist defaults (e.g., changed parameter values):
+ vars_1dwt_w_time defaults to true when one of the following is .true.:
+ do_transient_pfts, do_transient_crops, do_transient_lakes, do_transient_urban
+ else vars_1dwt_w_time defaults to .false.
+
+Changes to documentation:
+ Added vars_1dwt_w_time to namelist_definition_ctsm.xml with an explanation of its use
+
+Testing summary:
+----------------
+ [PASS means all tests PASS; OK means tests PASS other than expected fails.]
+
+  build-namelist tests (if CLMBuildNamelist.pm has changed):
+
+    derecho - PASS
+
+  regular tests (aux_clm: https://github.com/ESCOMP/CTSM/wiki/System-Testing-Guide#pre-merge-system-testing):
+
+    derecho ----- OK
+    izumi ------- OK
+
+Answer changes
+--------------
+
+Changes answers relative to baseline: Yes
+ - 1d_wt fields with the time dimension will display different answers in transient simulations, though this is diagnostic in nature.
+ - Only one test is affected in aux_clm: RXCROPMATURITYSKIPGEN_Ld1097.f10_f10_mg37.IHistClm60BgcCrop.derecho_intel.clm-cropMonthOutput
