     Notes on tags used in MITgcmUV
     ==============================
+o MNC:
+  - make myThid the last argument for all subroutines
+  - new default for the grid files: NO halos
+  - add useMNC and other run-time flags
+  - separate per-file-group handling of the unlimited dimension
+  - early initialization of MNC w/ flags read at the eeboot stage 
+    and lookup tables set in initialize_fixed
+  - write all MNC output to a freshly-created directory
+o thermodynamics sea-ice (thsice) is now tested with testreport.
+o test exp. advect_cs: use the standard cs32 grid ; update output.
 
+checkpoint52l_post
+o new land formulation:
+  a) use ground enthalpy as prognostic variable to ensure exact
+     energy conservation.
+  b) account for water temperature and for latent heat of freezing
+     in all processes (rain, run-off, ground storage)
+  c) compute surface and ground temperature implicitly.
+o aim_v23 modification for new land model:
+  a) Treat separately land / ocean / sea-ice surface fluxes
+     to allow implicit computation of land & sea-ice surface temp.
+  b) add snow precipitation.
+checkpoint52l_pre
+
+o fix problem (when 1 tile is empty) in min/max monitor.
+o fix bug in timeAve (u,vZetatave in common block) 
+o no restoring terms under ice for pkg/seaice
+o moved SEAICE_DO_DIAGS to S/R do_the_model_io
+o bug fix for pkg/seaice pickups
+o change MNC call locations and add coordinate attributes
+o mask vorticity at the corner ; affects global_ocean.cs output
+o fix ini_curvilinear_grid ; test CS experiments with mpi
+o aim.5l_cs: modify sea-ice fraction input file ; update output
+o exf: Adding simple range check routine for exf fields after read
+
+checkpoint52k_post
 o removed top-level directory "diags"
   - we migrated these functions to pkg/timeave a long time ago
 o fixed bug introduced in pkg/monitor
+o accuracy ctrlprec = 32 insuffient for gradient checks using
+  averaged fields (I/O via cost_averages)
+  -> use ctrl.h in active_file*.F to control I/O precision.
+o paramter list of CALL ADTHE_MAIN_LOOP
+o added initial do_the_model_io to ecco
+o set all ...Freq to zero after cost_final
+  taveFreq, dumpFreq, pChkptFreq
+o MAIN and ECCO differentiability restored
 
 checkpoint52j_post
 o fix nchklev in tamc.h for global_ocean...
