      Notes on tags used in MITgcmUV
      ==============================
- checkpoint47e_post
+ checkpoint50f_pre
- o created a tag prior to creating a branch
+  o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
+       + change Evap over land. (update aim.5l_cs output)
+  o added missing .cvsignores and made uniform across expts
+  o changed configuration of tidal_basin_2d expt
+  o added pkg/debug functions for tracing code in fatal crashes
+  o tidied pkg/monitor to use MONITOR_OPTIONS.h
+  o new fn in pkg/monitor to stop model if solution grows too big
+  o removed lots of single quotes from comments
+ checkpoint50e_post
+ o make KPP work with PTRACERS
+  - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
+    nearly a copy of kpp_transport_s
+  - there is no analogue to SurfaceTendencyS, so I have to use
+    gPtr(of the surface layer) instead
+ o add a new platform SunFire+mpi (SunFire 15000) to genmake
+ checkpoint50e_pre
+ checkpoint50d_post
+ o change kpp output from multiple-record state files to single-record state
+   files analogous to write_state.F
+ o reduce the output frequency of cg3d-related stuff to the monitor frequency,
+   analogous to the cg2d-related output.
+ o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
+   so that writing to internal file fn (with length 512) fails.
+ checkpoint50d_pre
+ checkpoint50c_post
+ o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
+ o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
+ o add time-average diagnostic of U*V and vertical diffusive flux for theta.
+ o bug fixed in convective adjustment diagnostic (multi-tile set-up).
+ o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
+ checkpoint50c_pre
+ Merging from release1_p13:
+ o bug fix for pkg/seaice dynamic solver
+ o Added SEAICE_initialHEFF to pkg/seaice
+ checkpoint50b_post
+ o store u*,v* in gU,V instead of in guNm1,gvNm1
+ o in order to put the momForcing out of the Adams-Bashforth:
+   move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
+   to timestep.F
+ o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
+ o re-generate output for highly sensitive test-exp:
+    global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
+ checkpoint50b_pre
+ o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
+ o corrected CPP option mismatch in exf_Bulk... functions for case
+   #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
+ checkpoint50a_post
+ o Bug fix for merging between c50 and KPP.
+   ikey was passed from thermodynamics to kpp_calc via
+   common block rather than being recomputed in kpp_calc,
+   in contradiction with new key itdkey.
+   New key ikppkey created, and tamc.h headers updated.
+ checkpoint50
+ - 2nd step of merge with ecco-branch:
+   merge changes in ecco-branch back into main trunk
+ - bug fix in find_alpha
+ - more storing in gmredi_calc_tensor.F, kpp_routines.F
+ - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
+ - merged some sliced AD support routines
+ checkpoint49
+ merged from ecco-branch:
+ o exf:
+   - Enable initialisation of forcing fields to constant
+     (runtime) values.
+   - in exf_getffields.F
+     Reduce i-/j-loop to interior domain, discarding overlaps.
+     That also fixes wrong TAF-key computations for key_1, key_2
+     with bulf formulae.
+   - exf_init.F modify #ifdef for exf_init_evap
+   - exf_getffieldrec.F, ctrl_getrec.F
+     The following INT-usages are not safe:
+       fldsecs  = int(fldsecs/fldperiod)*fldperiod
+       fldcount = int(fldsecs/fldperiod) + 1
+     and were modified.
+ o autodiff: checkpoint_lev...
+   - updated storing for bulk formulae (some arrays were missing)
+   - added state for seaice package
+   - synchronized with main branch
+ o DIVA:
+   Modif.s in
+   - the_main_loop.F
+   - the_model_main.F
+   and added cost_final_restore.F cost_final_store.F
+   o With these changes, it is possible to fully separate
+     the first forward run to compute the cost function (mdthe_main_loop)
+     and adjoint runs over individual DIVA intervals (adthe_main_loop)
+     into separate model executions.
+     This enables better tuning of DIVA to given queue sizes.
+   o Loss of cost function value in consecutive DIVA runs is
+     fixed by storing to 'costfinal' file.
+   o Appropriate call of ctrl_unpack/_pack,grdchk_main at
+     beginning/end of adjoint integration is accounted for.
+   The current changes apply to TAF-1.4.26.
+   TAF has one remaining bug, requiring one manual change
+   (see MITgcm manual).
+ o cal: synchronized between MAIN and ecco-branch
+ checkpoint48i_post
+ o Changes to restore differentiability of code w.r.t. previous tag
+   (mostly adding new routines to make list and replacing
+   pressure by totPhiHyd).
+ o Updated and merged grdchk package
+   - has both ADM and TLM checks
+   - works for single- and multi-proc.
+   - output cleaned
+   - worked successfully for parallel DIVA
+ o genmake:
+   - Adding -platform=SP4
+   - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
+ o Modif. for DIVA:
+   ctrl_unpack should not be called in intermediate DIVA interval.
+   (similar thing would apply for active files such as
+   tbar, sbar, psbar, which should not be reinitialised;
+   only relevant for ecco-branch)
+ checkpoint48h_post
+ o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
+ o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
+ o Added SEAICE_initialHEFF to pkg/seaice
+ o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
+ checkpoint48g_post
+ --- EOS:
+ o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
+   store total Potential in totPhyHyd for diagnostics & EOS.
+ o fix restart and overlap Pb when using Z-coord and EOS funct. of P
+ --- Pressure/geopotential gradient:
+ o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
+ o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
+   ( changes results of global_ocean_pressure )
+ o NLFS + z-coord.: add eta*Rho' contribution.
+ o accurate phiHyd when using interface-W at the middle between 2 centers
+  ( changes results of ideal_2D_oce )
+ o includes r* 2nd term in potential gradient.
+ checkpoint48f_post
+ Merging from release1_p12:
+ o Modifications for using pkg/exf with pkg/seaice
+   - improved description of the various forcing configurations
+   - added basic radiation bulk formulae to pkg/exf
+   - units/sign fix for evap computation in exf_getffields.F
+   - updated verification/global_with_exf/results/output.txt
+ o Added pkg/sbo for computing IERS Special Bureau for the Oceans
+   (SBO) core products, including oceanic mass, center-of-mass,
+   angular, and bottom pressure (see pkg/sbo/README.sbo).
+ o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
+   to avoid negative values in shallow regions.
+   - updated verification/natl_box/results/output.txt
+   - updated verification/lab_sea/results/output.txt
+ o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
+ o Added useSingleCpuIO option (see PARAMS.h).
+ o Updated useSingleCpuIO option in mdsio_writefield.F to
+   work with multi-field files, e.g., for single-file pickup.
+ o pkg/seaice:
+   - bug fix in growth.F: QNET for no shortwave case
+   - added HeffFile for specifying initial sea-ice thickness
+   - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
+ o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
+   kpp_transport_t.F, forward_step.F, and the_main_loop.F
+ o pkg/seaice:
+   - adjoint-friendly modifications
+   - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
+ checkpoint48e_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 hs94.1x64x5
+     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
+   (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
-Line 22 
 o Added a verification experiment for a
+Line 315 
 o Added a verification experiment for a
    -  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.
