     Notes on tags used in MITgcmUV
     ==============================
-o gmredi: fix few bugs and restore parameter values (e.g., Small_Number=1.D-12)
-  and scheme (e.g., Large_SlopeSqr=1.D+48) of checkpoint47f_post
+
+o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
+o dynamics: change definition of computational domain & adapt mom_fluxform
+  accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2. 
+o following exp works with Olx=Oly=2 (and pass through checkbounds option):
+    adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
+    exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5
+    global_ocean.90x40x15 global_with_exf global_ocean_pressure 
+    inverted_barometer solid-body.cs-32x32x1
+  (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
+
+checkpoint48d_post
+o in preparation for r*:
+ a) use pre-computed gradient of hydrostatic potential:
+    changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
+ b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
+    => affects results of glob_oce_pressure (different truncation error)  
+  update output.txt of ideal_2D_oce & global_ocean_pressure
+
+checkpoint48d_pre
+o in preparation for r*:
+  new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
+  pass the 2 comp. of the grad. as arguments to momentum S/R.
+  but for the moment, only used if it does not change the results. 
+o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
+
+checkpoint48c_post
+Modifications in treatment of initial flux forcing controls
+to avoid extra storing of flux fields.
+
+checkpoint48c_pre
+o Added tidal_basin_2d experiment (currently 1D!)
+o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented) 
+
+checkpoint48b_post
+o r* coordinate added in #ifdef NONLIN_FRSURF block.
+ (modification to pressure gradient not yet implemented)
+o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
+  (for U & V) that are used for vertical advection of momentum.
+
+checkpoint48a_post
+o In preparation for r*, use temp. array to compute vertical transport
+   in flux-form momentum pkg. => change results of few test-exp. 
+  Update output of: exp4, exp5, front_relax, global_ocean_pressure, 
+                    lab_sea, natl_box & plume_on_slope
 
 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
