     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint48
+o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
+
+checkpoint47j_post
+o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
+o moved adexch from forward_step to addummy_in_stepping
+o added exch in ctrl_map_...
+o aveFreq.=0. at end of cost_final to avoid overwrite in
+  reverse checkpointing loop
+o Yet more changes in gmredi:
+  * adgmredi_calc_tensor
+    avoiding all recomputation of gmredi_slope_limit
+  * adgmredi_x/y/rtransport
+    added flag for excessive storing to avoid recomp. of
+    u/v/rtans, dTdx/y/z
+    -> this is not really necessary and very memory-consuming
+  * adgmredi_slope_psi:
+    consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
+  * gmredi_slope_limit
+    re-activated full calculation of taperfct for case 'ac02'
+o updating verification/ adjoints of carbon, global_ocean.90x40x15
+
+checkpoint47i_post
+o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
+o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
+  default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
+o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf) 
+o gmredi: fix few bugs.
+
+checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
+This will be a good checkpoint to plug into the ecco-branch.
+o few modif.'s to get latest version adjointed
+  (mainly kick out code in ini_linear_phisurf)
+o modif's to run adjoint with exactConserv
+o case GM_BOLUS_ADVEC should be cleaned
+  S/R gmredi_slope_psi should be cleaned
+o verification/carbon now has exactConserv=.TRUE.
+
+checkpoint47g_post
+o time-average AIM output: becomes independent from statvars time-average
+  (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
+o After TAF bug fix:
+  Tested adjoint of gmredi package.
+  Tests were done with checkpoint47 rather than with latest
+  checkpoint47f_post since the latter is broken for the adjoint
+  verification/carbon/ contains both ADM and TLM gradient checks.
+Here they are, before they get changed/lost/stolen.
+Mostly modif.'s to fix numerical sensitivities.
+Gradient checks OK for
+- GM_taper_scheme:
+  * clipping
+  * ac02
+  * linear
+  * glw91
+  * dm95
+  * ldd97
+- GMREDI_OPTIONS:
+  * GM_VISBECK_VARIABLE_K
+  * GM_NON_UNITY_DIAGONAL
+  * GM_EXTRA_DIAGONAL
+  * GM_BOLUS_ADVEC
+in conjunction with data.gmredi parameters to be checked in
+in a few minutes under verification/carbon/code/
+
+checkpoint47f_post
+Merging from release1_p10:
+o modifications for using pkg/exf with pkg/seaice
+  - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
+    and SEAICE_EXTERNAL_FLUXES
+  - pkg/exf CPP options EXF_READ_EVAP and
+    EXF_NO_BULK_COMPUTATIONS
+  - usage examples are Experiments 8 and 9 in
+    verification/lab_sea/README
+  - verification/lab_sea default experiment now uses
+    pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
+
+checkpoint47e_post
+o created a tag prior to creating a branch
+
+checkpoint47d_post
+o fixed bug in the oceanic pressure coordinates code: vertical viscosity 
+  at the bottom boundary had an erroneous half slip boundary condition
+o added bottom drag and no slip boundary condition capabilities to 
+  oceanic pressure coordinates code
+o added new verification experiment global_ocean_pressure, this experiment is
+  also described in the tutorial section of the manual
+checkpoint47d_pre
+
+checkpoint47c_post
+o Added a verification experiment for a global cubed-sphere ocean run
+  -  verification/global_ocean.cubed32x32x30
+  -  uses pkg/therm_seaice and pkg/bulk_forcing
+
+o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
+o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
+  when using P-coordinate; only implemented for atmospheric config.
+o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
+  NOTES: requires option NONLIN_FRSURF to be "#define".
+o update advect_xz/results/output.txt (left from checkpoint44g_post)
+
 checkpoint47b_post
 Merging from release1_p9:
 o pkg/seaice
