     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint55a_post
+o merged code to 
+  * prescribe/read time-dependent open boundaries
+    (works in conjunction with exf, cal)
+  * sponge layer code for open boundaries
+  * each boundary N/S/E/W now has its own CPP option
+    (healthy for the adjoint)
+
+checkpoint55
+o up-to-date adjoint of previous breaks
+  - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
+  - global_ocean_ebm: adjoint still needs fix (TLM ok)
+  - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
+  - carbon: * remove tr1-related adjoint verification
+            * add ptracer as control variable
+o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
+  (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
+
+checkpoint54f_post
+o in verification/carbin/ remove experiment related to
+  ALLOW_PASSIVE_TRACER (array tr1 etc)
+  code_ad/ input_ad/ results_ad
+
+o add two new packages
+  - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
+    + subject to optimization (memory)
+  - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
+    + subject to reordering (many GOTOs in the original code)
+    + so far opps is called for every (i,j) point, and then operates in
+      the vertical; one may want to reorder the scheme in order operate in
+      horizontal slabs at the cost of (a lot of) memory, at least ten new 3D 
+      fields)
+o overhaul of IO so that we now have flags for MDSIO and/or MNC
+  - all verification tests compile and run with linux_ia32_g77
+  - defaults are compatible with current input files--nothing 
+    should change if you were not previously using MNC
+  - MNC output has been added in numerous places (eg. timeave)
+    but there are still a few writes not yet do-able with MNC
+    (this is in progress)
+  - flags now allow for either/or/both use of MDSIO and MNC and 
+    documentation will soon follow
+  - numerous small formatting cleanups for ProTeX
+o add version info (via BUILD_INFO.h) to MNC and stdout
+
+checkpoint54e_post
+o add two new packages
+  - pp81 (Packanowski and Philander, 1981), Richardson number and 
+    stratification dependent mixing
+  - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
+  - these scheme operate in a similar manner as KPP (without ghat, of 
+    course), however there is only one diffusivity that is used for both
+    temperature and salinity (and passive tracers)ç
+o add offline package
+o add "verification/dic_example" which contains a dic-gchem-ptracer setup
+  provided by Stephanie Dutkiewicz
+o genmake2: add ability to search for C compilers and cleanup test output
+  - fixes recent SX-6 problems and should help with others (eg. HP-UX)
+
+checkpoint54d_post
+o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
+o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong, 
+  leading to additional shift by 5 days each year of integration
+   (i.e. leading to considerable offset over the years)
+o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
+o start with no AB and no initial filtering (staggerTimeStep):
+  change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
+o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
+  (external loading & cpl import/export stay in forward_step.F)
+o update coupling interface to work with new staggerTimeStep
+o change MDSIO ptracers_pickup.
+o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
+o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
+o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
+
+checkpoint54c_post
+o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
+  this affects (truncation error) output.txt of test-exp:
+   global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
+o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
+o change Qnet to always be the net heat flux, (+upward).
+  affects (truncation error) output of natl_box exp.: updated
+o define the max number of passive tracers in PTRACERS_SIZE.h
+o start to test mnc routinely in exp0
+o add sea-ice loading (sIceLoad) as a new forcing field.
+
+checkpoint54b_post
+o add testreport "-j JOBS" option for parallel builds (tested and pretty 
+   impressive on Altix and Opteron systems)
+o diagnostics can now write NetCDF files through the mnc package
+o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
+o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added 
+o staggerTimeStep & NLFS: rescale T & S surface tendencies.
+  affects (truncation error) output of lab_sea & natl_box exp.: updated
+o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
+
+checkpoint54a_post
+o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
+o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
+o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
+o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
+  + internal_wave (shift in writing cg2d_ini_res)
+checkpoint54a_pre
+
+o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
+  - modified verification/lab_sea and natl_box_adjoint accordingly
+
+checkpoint54
+checkpoint53g_post
+o prepare splitting of thermodynamics: store convect.counter in common block
+o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
+  output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
+o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
+o new parameter "nShapS": allow to treat differently S from T (nShapT)
+o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
+o restore adjointability
+
+checkpoint53f_post
+o modifications that affect AIM experiment results (update output.txt):
+  - no advection of S at top interface Nr (pkg/generic_advdiff) 
+  - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
+o AIM pkg:
+  - include stability function into surf.Flux derivative relative to Tsurf
+  - calculate clear-sky radiation & surface temp. change (for diagnostics)
+ 
+checkpoint53e_post
+o merged cylindrical coord configuration
+o added rotating_tank experiment
+checkpoint53e_pre
+
+checkpoint53d_post
+o faulks upgraded: re-generate output.txt that have changed:
+   global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
+o Added Bryan and Lewis, 1979, vertical diffusivity profile
+o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing. 
+o added Sadourny discretization of Coriolis
+  - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
+  - re-enabled use of omega3 (useAbsVorticity)
+o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
+  vector-invariant equations
+  - note: does *NOT* yet use same variable visc. for no-slip BC's.
+o recoded the lateral boundary conditions for non-hydrostatic w, this time
+  hopefully without new bugs
+  - still to do: biharmonic friction for non-hydrostatic w
+o bug fix for mom_*_sidedrag: rA -> rAs,rAw
+o regenerated output for global_ocean_ebm (using -ieee)
+o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
+  of mom_common/
+  - simple re-arrangement of instructions within computing loop
+checkpoint53d_pre
+
+checkpoint53c_post
+o new version of coupler for AIM+thSIce and Ocean models
+ - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
+ - land: change Evaporation of snow
+ - aim with thSIce: fix bug in snow-precip.
+o changes to calc_gw.F
+ - bug fix for w^2 term near the bottom boundary
+ - (hopefully) improve the lateral slip boundary condtions for use with
+    partial/looped cells
+  - because the bug fix changes two verification experiments anyway (exp5
+    and plume on slope), change the lateral boundary condition from half slip
+    to the value of no_slip_sides
+o ebm package wasnt quite up to the parallel task. Fixed that.
+o Adjoint of EBM package + verification
+  * TLM OK
+  * ADM not sufficient accuracy yet (needs further testing)
+
+checkpoint53b_post
+o Commiting new energy balance model to repository
+  * package is pkg/ebm
+  * verif. is verification/global_ocean_ebm
+  * references are in ebm_driver.F
+C      * X. Wang, P. Stone and J. Marotzke, 1999:
+C        Global thermohaline circulation. Part I:
+C        Sensitivity to atmospheric moisture transport.
+C        J. Climate 12(1), 71-82
+C      * X. Wang, P. Stone and J. Marotzke, 1999:
+C        Global thermohaline circulation. Part II:
+C        Sensitivity with interactive transport.
+C        J. Climate 12(1), 83-91
+C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
+C        Destabilization of the thermohaline circulation
+C        by atmospheric eddy transports.
+C        J. Climate 7(12), 1870-1882
+o Will need long integration testing.
