3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  o more obcs stuff
7  o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F    - added obcs_external_fields_load as an alternative to the EXF-pkg option
8        for reading boundary values. This routine is called from
9        obcs_prescribe_read
10      - updated obcs_check
11    
12    checkpoint55c_post
13    o obcs stuff
14      - new runtime flags useOBCSprescribe, useOBCSbalance
15      - re-arranged obcs_calc
16      - moved exf_getobcs to obcs_prescibe_read
17        obcs_prescibe_read is called after ORLANSKI stuff
18        and independent of it (executable can contain all).
19      - updated obcs_check
20      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
21        These may be necessary only if tangential velocities are
22        prescribed at OB, not sure, needs testing.
23    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
24      which simplifies the calls and passes the ifc check-bounds test
25    
26    checkpoint55b_post
27    o add a 2D scalar, Z location, exchange_2 routine.
28    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
29      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
30      affects advect_cs results (for the wrong reason): update output.txt
31    o use a more standard discretization for biharmonic viscosity ;
32     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
33      affects results of dome set-up: update output.txt
34    o fix gad_advection.F (CubedSphere part), back to version 1.23
35    o fix bug in mom_vi_del2uv.F (CubedSphere part).
36    
37    checkpoint55a_post
38    o merged code to
39      * prescribe/read time-dependent open boundaries
40        (works in conjunction with exf, cal)
41      * sponge layer code for open boundaries
42      * each boundary N/S/E/W now has its own CPP option
43        (healthy for the adjoint)
44    
45    checkpoint55
46    o up-to-date adjoint of previous breaks
47      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
48      - global_ocean_ebm: adjoint still needs fix (TLM ok)
49      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
50      - carbon: * remove tr1-related adjoint verification
51                * add ptracer as control variable
52    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
53      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
54    
55    checkpoint54f_post
56    o in verification/carbin/ remove experiment related to
57      ALLOW_PASSIVE_TRACER (array tr1 etc)
58      code_ad/ input_ad/ results_ad
59    
60    o add two new packages
61      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
62        + subject to optimization (memory)
63      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
64        + subject to reordering (many GOTOs in the original code)
65        + so far opps is called for every (i,j) point, and then operates in
66          the vertical; one may want to reorder the scheme in order operate in
67          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
68          fields)
69    o overhaul of IO so that we now have flags for MDSIO and/or MNC
70      - all verification tests compile and run with linux_ia32_g77
71      - defaults are compatible with current input files--nothing
72        should change if you were not previously using MNC
73      - MNC output has been added in numerous places (eg. timeave)
74        but there are still a few writes not yet do-able with MNC
75        (this is in progress)
76      - flags now allow for either/or/both use of MDSIO and MNC and
77        documentation will soon follow
78      - numerous small formatting cleanups for ProTeX
79    o add version info (via BUILD_INFO.h) to MNC and stdout
80    
81    checkpoint54e_post
82    o add two new packages
83      - pp81 (Packanowski and Philander, 1981), Richardson number and
84        stratification dependent mixing
85      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
86      - these scheme operate in a similar manner as KPP (without ghat, of
87        course), however there is only one diffusivity that is used for both
88        temperature and salinity (and passive tracers)ç
89    o add offline package
90    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
91      provided by Stephanie Dutkiewicz
92    o genmake2: add ability to search for C compilers and cleanup test output
93      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
94    
95    checkpoint54d_post
96    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
97    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
98      leading to additional shift by 5 days each year of integration
99       (i.e. leading to considerable offset over the years)
100    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
101    o start with no AB and no initial filtering (staggerTimeStep):
102      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
103    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
104      (external loading & cpl import/export stay in forward_step.F)
105    o update coupling interface to work with new staggerTimeStep
106    o change MDSIO ptracers_pickup.
107    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
108    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
109    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
110    
111    checkpoint54c_post
112    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
113      this affects (truncation error) output.txt of test-exp:
114       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
115    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
116    o change Qnet to always be the net heat flux, (+upward).
117      affects (truncation error) output of natl_box exp.: updated
118    o define the max number of passive tracers in PTRACERS_SIZE.h
119    o start to test mnc routinely in exp0
120    o add sea-ice loading (sIceLoad) as a new forcing field.
121    
122    checkpoint54b_post
123    o add testreport "-j JOBS" option for parallel builds (tested and pretty
124       impressive on Altix and Opteron systems)
125    o diagnostics can now write NetCDF files through the mnc package
126    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
127    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
128    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
129      affects (truncation error) output of lab_sea & natl_box exp.: updated
130    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
131    
132    checkpoint54a_post
133    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
134    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
135    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
136    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
137      + internal_wave (shift in writing cg2d_ini_res)
138    checkpoint54a_pre
139    
140    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
141      - modified verification/lab_sea and natl_box_adjoint accordingly
142    
143    checkpoint54
144    checkpoint53g_post
145    o prepare splitting of thermodynamics: store convect.counter in common block
146    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
147      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
148    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
149    o new parameter "nShapS": allow to treat differently S from T (nShapT)
150    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
151    o restore adjointability
152    
153    checkpoint53f_post
154    o modifications that affect AIM experiment results (update output.txt):
155      - no advection of S at top interface Nr (pkg/generic_advdiff)
156      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
157    o AIM pkg:
158      - include stability function into surf.Flux derivative relative to Tsurf
159      - calculate clear-sky radiation & surface temp. change (for diagnostics)
160    
161    checkpoint53e_post
162    o merged cylindrical coord configuration
163    o added rotating_tank experiment
164    checkpoint53e_pre
165    
166    checkpoint53d_post
167    o faulks upgraded: re-generate output.txt that have changed:
168       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
169    o Added Bryan and Lewis, 1979, vertical diffusivity profile
170    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
171    o added Sadourny discretization of Coriolis
172      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
173      - re-enabled use of omega3 (useAbsVorticity)
174    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
175      vector-invariant equations
176      - note: does *NOT* yet use same variable visc. for no-slip BC's.
177    o recoded the lateral boundary conditions for non-hydrostatic w, this time
178      hopefully without new bugs
179      - still to do: biharmonic friction for non-hydrostatic w
180    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
181    o regenerated output for global_ocean_ebm (using -ieee)
182    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
183      of mom_common/
184      - simple re-arrangement of instructions within computing loop
185    checkpoint53d_pre
186    
187    checkpoint53c_post
188    o new version of coupler for AIM+thSIce and Ocean models
189     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
190     - land: change Evaporation of snow
191     - aim with thSIce: fix bug in snow-precip.
192    o changes to calc_gw.F
193     - bug fix for w^2 term near the bottom boundary
194     - (hopefully) improve the lateral slip boundary condtions for use with
195        partial/looped cells
196      - because the bug fix changes two verification experiments anyway (exp5
197        and plume on slope), change the lateral boundary condition from half slip
198        to the value of no_slip_sides
199    o ebm package wasnt quite up to the parallel task. Fixed that.
200    o Adjoint of EBM package + verification
201      * TLM OK
202      * ADM not sufficient accuracy yet (needs further testing)
203    
204    checkpoint53b_post
205    o Commiting new energy balance model to repository
206      * package is pkg/ebm
207      * verif. is verification/global_ocean_ebm
208      * references are in ebm_driver.F
209    C      * X. Wang, P. Stone and J. Marotzke, 1999:
210    C        Global thermohaline circulation. Part I:
211    C        Sensitivity to atmospheric moisture transport.
212    C        J. Climate 12(1), 71-82
213    C      * X. Wang, P. Stone and J. Marotzke, 1999:
214    C        Global thermohaline circulation. Part II:
215    C        Sensitivity with interactive transport.
216    C        J. Climate 12(1), 83-91
217    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
218    C        Destabilization of the thermohaline circulation
219    C        by atmospheric eddy transports.
220    C        J. Climate 7(12), 1870-1882
221    o Will need long integration testing.
222    checkpoint53b_pre
223    
224    o created pkg/mom_common in preparation for variable viscosity code
225    o renamed and split ini_mnc_io
226    o pkg/land: only liquid water can diffuse or run-off
227    o AIM using land: soil wetness availability account for snow
228    o added printMapIncludesZeros to EEPARMS namelist
229    
230    checkpoint53a_post
231    o restore TAMC compatiility for exf_constants.h
232      (no usage of _d in .h)
233    o Additional storing in KPP in an attempt to fix
234      TAMC problem with adjoint of KPP code.
235      (no success...)
236      Identical code works fine with TAF.
237    o Fixed verification/natl_box_adjoint experiments.
238      Initial conditions for Experiments 4 and 5 are now
239      set to "SEAICE_initialHEFF=0", which is more reasonable,
240      and hence gives results closer to that of Experiment 2.
241      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
242    
243    checkpoint53
244    o stable checkpoint with up to date adjoint
245      TLM tests only run for 1st grdchk at the moment. Its unclear if
246      this is a code problem or a problem with resetting code for g_
247      variables that is being autogenerated wrong.
248      Otherwise:
249       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
250       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
251         are both still in chaos following their security messes.
252    
253    checkpoint52n_post
254    o various build (mostly genmake2) changes including:
255      - ability to build/run more easily within Cygwin and MacOS X
256      - more complicated Makefiles with a stronger dependence on Gnu Make
257    o pkg/seaice modifications
258      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
259        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
260        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
261      - changed proxy for geostrophic velocity and updated
262        verification/lab_sea/results/* accordingly
263      - removed ADI dynamic solver from pkg/seaice
264      - replaced all occurrences of 1/CSTICE or 1/CSUICE
265        they caused a segmentation fault under certain circumstances
266      - removed unused field WATR
267    o bug fix in exf-package:
268      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
269         now reflect that.
270    o small fixes in the cal-package:
271      - set reference date to first of January for the 'model'-calendar
272      - failing of cal_CheckDate in cal_FullDate now actually results in a
273        warning
274    o small modifications in exf-package to increase flexibility:
275      - change climtempfreeze from a constant to a runtime parameter that
276        is specified in data.exf_clim (default = -1.9)
277      - introduce runtime parameter windstressmax (default = 2.0) that is
278        specified in data.exf
279    o fix in pkg/thsice:
280      - update Evap (Tsf changes) to be consistent with Latent heat flux
281      - maintain snow precipitation unchanged (even if Tsf >=0).
282     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
283    
284    checkpoint52m_post
285    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
286      this does not change any of the results, because myIter=0 in swfrac always
287      lead to jwtype=2 (the default anyway), but the call makes little sense
288      as a default
289    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
290    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
291      atmospheric model (AIM) to use it ; add a "slab ocean" component.
292    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
293    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
294    o extending useSingleCpuIO option to work with new exch2 I/O format
295      - old-style, missing-tile I/O is still accessible by defining CPP
296        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
297    o monitor package can write to NetCDF files and/or STDOUT
298    o fix re-definition bug in MNC_GRID_INIT_ALL()
299    o doc/api_reference added
300      - a framework for building an API Reference Manual using all
301        the "protex" comments embedded in the code
302      - see pkg/generic_advdiff, pkg/mnc for examples
303    o MNC:
304      - make myThid the last argument for all subroutines
305      - new default for the grid files: NO halos
306      - add useMNC and other run-time flags
307      - separate per-file-group handling of the unlimited dimension
308      - early initialization of MNC w/ flags read at the eeboot stage
309        and lookup tables set in initialize_fixed
310      - write all MNC output to a freshly-created directory
311    o thermodynamics sea-ice (thsice) is now tested with testreport.
312    o test exp. advect_cs: use the standard cs32 grid ; update output.
313    o Added functionality to grdchk:
314      pick global i,j,k position (or nearest wet) where to perform check.
315    
316    checkpoint52l_post
317    o new land formulation:
318      a) use ground enthalpy as prognostic variable to ensure exact
319         energy conservation.
320      b) account for water temperature and for latent heat of freezing
321         in all processes (rain, run-off, ground storage)
322      c) compute surface and ground temperature implicitly.
323    o aim_v23 modification for new land model:
324      a) Treat separately land / ocean / sea-ice surface fluxes
325         to allow implicit computation of land & sea-ice surface temp.
326      b) add snow precipitation.
327    checkpoint52l_pre
328    
329    o fix problem (when 1 tile is empty) in min/max monitor.
330    o fix bug in timeAve (u,vZetatave in common block)
331    o no restoring terms under ice for pkg/seaice
332    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
333    o bug fix for pkg/seaice pickups
334    o change MNC call locations and add coordinate attributes
335    o mask vorticity at the corner ; affects global_ocean.cs output
336    o fix ini_curvilinear_grid ; test CS experiments with mpi
337    o aim.5l_cs: modify sea-ice fraction input file ; update output
338    o exf: Adding simple range check routine for exf fields after read
339    
340    checkpoint52k_post
341    o removed top-level directory "diags"
342      - we migrated these functions to pkg/timeave a long time ago
343    o fixed bug introduced in pkg/monitor
344    o accuracy ctrlprec = 32 insuffient for gradient checks using
345      averaged fields (I/O via cost_averages)
346      -> use ctrl.h in active_file*.F to control I/O precision.
347    o paramter list of CALL ADTHE_MAIN_LOOP
348    o added initial do_the_model_io to ecco
349    o set all ...Freq to zero after cost_final
350      taveFreq, dumpFreq, pChkptFreq
351    o MAIN and ECCO differentiability restored
352    
353    checkpoint52j_post
354    o fix nchklev in tamc.h for global_ocean...
355    o Bringing flow and store directives up-to-date
356    o Really weird thing!
357      call do_the_model_io from the_main_loop with parameters
358      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
359      TAF places a faulty re-call of initialise_varia
360      after cost_final call which should not be there!
361    checkpoint52j_pre
362    
363    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
364      error messages
365    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
366    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
367      debug output
368    o modfied mdsio_writefield.F to handle non-global files under exch2
369    o update AIM Cubed-Sphere exp (aim.5l_cs):
370      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
371    o update AIM Equatorial Channel exp:
372      use standard aim_v23 pkg and change the SST fields to be more realistic.
373    o globalFile now works with exch2
374    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
375      mon_vort3.F to make exch2 friendly with >1 tile per cube face
376    o limit timeave output for hi-res integrations
377    
378    checkpoint52i_post
379    o removed CPP_EEOPTIONS.h from verification/*/code
380    o updated the tiling for global_ocean_pressure
381    checkpoint52i_pre
382    
383    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
384      the old pkg/aim).
385    
386    checkpoint52h_pre
387    o shortened offending lines in exch2_send_rx?.template
388    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
389    o genmake2: add build & execute test for NetCDF code

393    o added temporary hack for sea-ice dynamics on the cube:
394      metric terms are ignored and it is assumed that
395      there is no sea-ice on cube faces 1, 2, 4, and 5.
396    
397    checkpoint52f_post
398    o added exch2 cube routines to pkg/exch2

405      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
406    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
407      to work with implicit vertical advection and AB ;
408    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
409    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
410     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
411    checkpoint52e_pre
412    
413    o fix bug in impldiff when Nr=1 or Nr=2.
414    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
415    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
416    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

426        random number generator
427    o add infrastructure in model routines for fizhi and gridalt packages
428    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
429    o changes to permit hi-res, cubed-sphere, configuration
430      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
431      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
432      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
433        of surface winds for the cube
434      (A verification experiment, based on global_ocean.cs32x15, but with
435       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
436       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
437       complete with example surface forcing files and matlab scripts to look
438       at the output and compare it with that of global_ocean.cs32x15.)
439    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
440       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
441       to conform to the common rule.
442    o check-in the first version of the coupler + interfaces for multi-components
443       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
444       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
445       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
446       - ocean and atmos. share the same horizontal grid (no interpolation).
447       - exchanges between component and coupler is done in forward_step
448    o new verification experiment, cpl_aim+ocn:
449       coupled ocean - AIM atmosphere on cs32 grid.
450    
451    checkpoint52d_pre
452    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
453    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
454    
455    checkpoint52c_post
456    o Fixing OPTIONS files for use of exf:
457      - ALLOW_ECCO not needed
458      - ECCO_CPPOPTIONS.h should not be included from
459        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
460        as has been the case in the past
461      - All cal/exf related options are currently set in
462        single header file. Should remain so until we
463        agree on a consistent new policy.
464    o Removed all CPP options for cal package.
465      cal has no more CPP options.
466    o modified STOREs in GAD_ADVECTION
467    o corrected key comp. for passkey
468    
469    checkpoint52b_post

472     - modify fluxes but do not change theta directly;
473     - light cleaning of bulk_force pkg (still needed with thsice).
474     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
475       + output_thsice.txt to test thsice & bulk_force pkgs.
476    o put back grid & coriolis monitor output.
477    checkpoint52b_pre
478    
479    o call "do_the_model_io" at the beginning (=> dump initial state)
480    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
481    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
482      (need info on NUMBER_OF_PTRACERS)
483    o missing PTRACERS headers in some routines
484    o default tamc.h in pkg/autodiff supposed to crash
485      to ensure proper customization
486    
487    checkpoint52a_post
488    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
489      - moved surfaceTendencyTice from pkg/seaice to main code
490      - subroutine FREEZE_SURFACE now limits only surface temperature
491        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
492        => new output.txt for global_ocean.cs32x15 & global_with_exf
493      - keep the old version of FREEZE for backward compatibility;
494        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

503    o some bug fixes for #undef REAL4_IS_SLOW
504    
505    checkpoint52 = ecco_c52_e35
506    o after testing adjoints of checkpoint51u_post
507    
508    checkpoint51u_post
509    o this is the post-merge tag of the ecco-branch
510      (needs another clean checkout and re-testing)
511    o various natl_box_adjoint configs and results
512      but no input fields
513    o obcs adjoint not yet merged!
514    o adding ECCO global 1x1 and 2x2 degree configs
515    o updated/extended some store directives for seaice
516    o pkg/ecco now containes ecco-specific part of cost function

518      supersede those in model/src/
519      previous input data.cost now in data.ecco
520      (new namelist ecco_cost_nml)
521    o in ctrl/ cleaned some cross-dependencies and updated CPP options
522    
523    checkpoint51t_post
524    o this is the pre-merge tag of the ecco-branch
525    
526    checkpoint51s_post
527    o cleanup: removed various obsolete #define-s
528    o pkg/grdchk
529      - renamed 'ph-grd 3' to 'grad-res'
530      - merged from ecco-branch
531        (remaining bug fixes for obcs gradient checks)
532      - additional high-precision output for testreport
533        (grep for 'precision_grdchk_result')
534    
535    checkpoint51r_post
536    o cleaned up or removed CPP_OPTIONS.h files
537    o updated results for some of the tests to reflect the new
538      optfiles (-ieee: -O0 instead of -O3)
539    
540    checkpoint51q_post
541    o cd_code:
542      - moved cd_scheme.F -> cd_code_scheme.F
543      - separate read_checkpoint from cd_code_ini_vars.F

554    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
555    
556    checkpoint51p_post
557    o create initial cd_code package
558      - WARNING: the initialization of fields within packages
559        is broken because INI_FIELDS (where READ_CHECKPOINT is
560        called) is called *before* PACKAGES_INIT_VARIABLES.
561        This seems to be backwards since
562        1) its important to initially zero the entire field including
563           the "halo" region
564        2) zeroing needs to be done *before* reading pickup info
565           and the pickup call might or might not happen in any
566           particular run
567      - this needs an overhaul for R2
568    o cleanup verification/*/code/GMREDI_OPTIONS.h
569    o cleanup testreport

808    checkpoint50e_post
809    o make KPP work with PTRACERS
810     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
811       nearly a copy of kpp_transport_s
812     - there is no analogue to SurfaceTendencyS, so I have to use
813       gPtr(of the surface layer) instead
814    o add a new platform SunFire+mpi (SunFire 15000) to genmake
815    checkpoint50e_pre
816    
817    checkpoint50d_post
818    o change kpp output from multiple-record state files to single-record state
819      files analogous to write_state.F
820    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
821      analogous to the cg2d-related output.
822    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
823      so that writing to internal file fn (with length 512) fails.
824    checkpoint50d_pre
825    
826    checkpoint50c_post
827    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
828    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
829    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
830    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
831    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
832    
833    checkpoint50c_pre
834    Merging from release1_p13:
835    o bug fix for pkg/seaice dynamic solver
836  o Added SEAICE_initialHEFF to pkg/seaice  o Added SEAICE_initialHEFF to pkg/seaice
 o SEAICE_WRITE_PICKUP needs to be called before WRITE_CHECKPOINT  
837    
838  release1_p12  checkpoint50b_post
839  o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,  o store u*,v* in gU,V instead of in guNm1,gvNm1
840    kpp_transport_t.F, forward_step.F, and the_main_loop.F  o in order to put the momForcing out of the Adams-Bashforth:
841  o pkg/seaice:    move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
842    - adjoint-friendly modifications    to timestep.F
843    - added a SEAICE_WRITE_PICKUP at end of the_model_main.F  o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
844    o re-generate output for highly sensitive test-exp:
845       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
846    
847  release1_p12_pre  checkpoint50b_pre
848  o Updated useSingleCpuIO option in mdsio_writefield.F to  o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
849    work with multi-field files, e.g., for single-file pickup.  o corrected CPP option mismatch in exf_Bulk... functions for case
850  o pkg/seaice:    #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
851    - bug fix in growth.F: QNET for no shortwave case  
852    - added HeffFile for specifying initial sea-ice thickness  checkpoint50a_post
853    - changed SEAICE_EXTERNAL_FLUXES wind stress implementation  o Bug fix for merging between c50 and KPP.
854      ikey was passed from thermodynamics to kpp_calc via
855      common block rather than being recomputed in kpp_calc,
856      in contradiction with new key itdkey.
857      New key ikppkey created, and tamc.h headers updated.
858    
859    checkpoint50
860    - 2nd step of merge with ecco-branch:
861      merge changes in ecco-branch back into main trunk
862    - bug fix in find_alpha
863    - more storing in gmredi_calc_tensor.F, kpp_routines.F
864    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
865    - merged some sliced AD support routines
866    
867  release1_p11  checkpoint49
868    merged from ecco-branch:
869    o exf:
870      - Enable initialisation of forcing fields to constant
871        (runtime) values.
872      - in exf_getffields.F
873        Reduce i-/j-loop to interior domain, discarding overlaps.
874        That also fixes wrong TAF-key computations for key_1, key_2
875        with bulf formulae.
876      - exf_init.F modify #ifdef for exf_init_evap
877      - exf_getffieldrec.F, ctrl_getrec.F
878        The following INT-usages are not safe:
879          fldsecs  = int(fldsecs/fldperiod)*fldperiod
880          fldcount = int(fldsecs/fldperiod) + 1
881        and were modified.
882    o autodiff: checkpoint_lev...
883      - updated storing for bulk formulae (some arrays were missing)
884      - added state for seaice package
885      - synchronized with main branch
886    o DIVA:
887      Modif.s in
888      - the_main_loop.F
889      - the_model_main.F
890      and added cost_final_restore.F cost_final_store.F
891      o With these changes, it is possible to fully separate
892        the first forward run to compute the cost function (mdthe_main_loop)
893        and adjoint runs over individual DIVA intervals (adthe_main_loop)
894        into separate model executions.
895        This enables better tuning of DIVA to given queue sizes.
896      o Loss of cost function value in consecutive DIVA runs is
897        fixed by storing to 'costfinal' file.
898      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
899        beginning/end of adjoint integration is accounted for.
900      The current changes apply to TAF-1.4.26.
901      TAF has one remaining bug, requiring one manual change
902      (see MITgcm manual).
903    o cal: synchronized between MAIN and ecco-branch
904    
905    checkpoint48i_post
906    o Changes to restore differentiability of code w.r.t. previous tag
907      (mostly adding new routines to make list and replacing
908      pressure by totPhiHyd).
909    o Updated and merged grdchk package
910      - has both ADM and TLM checks
911      - works for single- and multi-proc.
912      - output cleaned
913      - worked successfully for parallel DIVA
914    o genmake:
915      - Adding -platform=SP4
916      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
917    o Modif. for DIVA:
918      ctrl_unpack should not be called in intermediate DIVA interval.
919      (similar thing would apply for active files such as
920      tbar, sbar, psbar, which should not be reinitialised;
921      only relevant for ecco-branch)
922    
923    checkpoint48h_post
924    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
925    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
926    o Added SEAICE_initialHEFF to pkg/seaice
927    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
928    
929    checkpoint48g_post
930    --- EOS:
931    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
932      store total Potential in totPhyHyd for diagnostics & EOS.
933    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
934    --- Pressure/geopotential gradient:
935    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
936    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
937      ( changes results of global_ocean_pressure )
938    o NLFS + z-coord.: add eta*Rho' contribution.
939    o accurate phiHyd when using interface-W at the middle between 2 centers
940     ( changes results of ideal_2D_oce )
941    o includes r* 2nd term in potential gradient.
942    
943    checkpoint48f_post
944    Merging from release1_p12:
945  o Modifications for using pkg/exf with pkg/seaice  o Modifications for using pkg/exf with pkg/seaice

958  o Added useSingleCpuIO option (see PARAMS.h).  o Added useSingleCpuIO option (see PARAMS.h).
959    o Updated useSingleCpuIO option in mdsio_writefield.F to
960      work with multi-field files, e.g., for single-file pickup.
961    o pkg/seaice:
962      - bug fix in growth.F: QNET for no shortwave case
963      - added HeffFile for specifying initial sea-ice thickness
964      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
965    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
966      kpp_transport_t.F, forward_step.F, and the_main_loop.F
967    o pkg/seaice:
968      - adjoint-friendly modifications
969      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
970    
971    checkpoint48e_post
972    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
973    o dynamics: change definition of computational domain & adapt mom_fluxform
974      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
975    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
976        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
977        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
978        global_ocean.90x40x15 global_with_exf global_ocean_pressure
979        inverted_barometer solid-body.cs-32x32x1
980      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
981    
982    checkpoint48d_post
983    o in preparation for r*:
984     a) use pre-computed gradient of hydrostatic potential:
985        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
986     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
987        => affects results of glob_oce_pressure (different truncation error)  
988      update output.txt of ideal_2D_oce & global_ocean_pressure
989    
990    checkpoint48d_pre
991    o in preparation for r*:
992      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
993      pass the 2 comp. of the grad. as arguments to momentum S/R.
994      but for the moment, only used if it does not change the results.
995    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
996    
997    checkpoint48c_post
998    Modifications in treatment of initial flux forcing controls
999    to avoid extra storing of flux fields.
1000    
1001    checkpoint48c_pre
1002    o Added tidal_basin_2d experiment (currently 1D!)
1003    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1004    
1005    checkpoint48b_post
1006    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1007     (modification to pressure gradient not yet implemented)
1008    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1009      (for U & V) that are used for vertical advection of momentum.
1010    
1011    checkpoint48a_post
1012    o In preparation for r*, use temp. array to compute vertical transport
1013       in flux-form momentum pkg. => change results of few test-exp.
1014      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1015                        lab_sea, natl_box & plume_on_slope
1016    
1017    checkpoint48
1018    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1019    
1020    checkpoint47j_post
1021    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1022    o moved adexch from forward_step to addummy_in_stepping
1023    o added exch in ctrl_map_...
1024    o aveFreq.=0. at end of cost_final to avoid overwrite in
1025      reverse checkpointing loop
1026    o Yet more changes in gmredi:
1027      * adgmredi_calc_tensor
1028        avoiding all recomputation of gmredi_slope_limit
1029      * adgmredi_x/y/rtransport
1030        added flag for excessive storing to avoid recomp. of
1031        u/v/rtans, dTdx/y/z
1032        -> this is not really necessary and very memory-consuming
1033      * adgmredi_slope_psi:
1034        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1035      * gmredi_slope_limit
1036        re-activated full calculation of taperfct for case 'ac02'
1037    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1038    
1039    checkpoint47i_post
1040    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1041    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1042      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1043    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1044    o gmredi: fix few bugs.
1045    
1046    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1047    This will be a good checkpoint to plug into the ecco-branch.
1048    o few modif.'s to get latest version adjointed
1049      (mainly kick out code in ini_linear_phisurf)
1050    o modif's to run adjoint with exactConserv
1051    o case GM_BOLUS_ADVEC should be cleaned
1052      S/R gmredi_slope_psi should be cleaned
1053    o verification/carbon now has exactConserv=.TRUE.
1054    
1055    checkpoint47g_post
1056    o time-average AIM output: becomes independent from statvars time-average
1057      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1058    o After TAF bug fix:
1059      Tested adjoint of gmredi package.
1060      Tests were done with checkpoint47 rather than with latest
1061      checkpoint47f_post since the latter is broken for the adjoint
1062      verification/carbon/ contains both ADM and TLM gradient checks.
1063    Here they are, before they get changed/lost/stolen.
1064    Mostly modif.'s to fix numerical sensitivities.
1065    Gradient checks OK for
1066    - GM_taper_scheme:
1067      * clipping
1068      * ac02
1069      * linear
1070      * glw91
1071      * dm95
1072      * ldd97
1073    - GMREDI_OPTIONS:
1074      * GM_VISBECK_VARIABLE_K
1075      * GM_NON_UNITY_DIAGONAL
1076      * GM_EXTRA_DIAGONAL
1077      * GM_BOLUS_ADVEC
1078    in conjunction with data.gmredi parameters to be checked in
1079    in a few minutes under verification/carbon/code/

1099    o added bottom drag and no slip boundary condition capabilities to
1100      oceanic pressure coordinates code
1101    o added new verification experiment global_ocean_pressure, this experiment is
1102      also described in the tutorial section of the manual
1103    checkpoint47d_pre
1104    
1105    checkpoint47c_post
1106    o Added a verification experiment for a global cubed-sphere ocean run
1107      -  verification/global_ocean.cubed32x32x30
1108      -  uses pkg/therm_seaice and pkg/bulk_forcing
1109    
1110    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1111    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1112      when using P-coordinate; only implemented for atmospheric config.
1113    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1114      NOTES: requires option NONLIN_FRSURF to be "#define".
1115    o update advect_xz/results/output.txt (left from checkpoint44g_post)

1135    o new pkg: aim_v23
1136     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1137       for now, keep the same surface forcing as before.
1138     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1139     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1140     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1141    o add diagnostic of surface correction term in monitor output
1142    
1143    o bulk_force and therm_seaice
1144    - Two packages:  bulk_force (Bulk forcing)
1145      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1146    - Earlier integration from Stephaine Dutkiewicz
1147      and Patrick Heimbach.

1157        - GM_NON_UNITY_DIAGONAL
1158        - GM_EXTRA_DIAGONAL
1159        - GM_BOLUS_ADVEC )
1160      * However, wrong gradient check problem remains unsolved.
1161      * New CPP options have been introduced for different
1162        tapering schemes
1163    o external_fields_load now part of differentiation list
1164    o pressure needs multiple storing;
1165      would be nice to have store_pressure at beginning or
1166      end of forward_step, e.g. by having phiHyd global (5-dim.)
1167      (NB: pressure is needed for certain cases in find_rho,
1168      which is also invoked through convective_adjustment).
1169    o recomputations in find_rho for cases
1170     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1171    o #define ATMOSPHERIC_LOADING should be differentiable
1172    o ini_forcing shifted to begining of initialise_varia

1237      and new routine quasihydrostaticterms()
1238    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1239      New routine: mom_u_coriolis_nh()
1240    o fixed sign of non-hydrostatic metric terms in u and v equations.
1241      Depend on correct sign of gravitySign.
1242    o added work.pc* to .cvsignore in aim directories using ifc
1243    o introduced flag for controllin non-hydrostatic metric terms
1244    o removed gravitySign from PARM04
1245    o switched to g77/ifc from pgf77 in aim experiments
1246    
1247    checkpoint46l_post
1248    o made convective adjustment work with pressure coordinates:
1249     - changed the direction of k-loop in convective_adjustment.F for the
1250       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1251     - adjusted the reference pressure k-index in convective_adjustment.F
1252     - adjusted the convection condition in convect.F (in analogy to
1253       calc_ivdc.F)
1254     - convective_adjustment no longer computes anything on the halos
1255     - removed the warnings about negative salinity from find_rho.F and
1256       find_alpha.F; instead the new routine look_for_neg_salinity, called
1257       at the beginning of find_rho, find_alpha, and find_beta, does a
1258       check of the entire slice, if CPP-option
1259       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1260    checkpoint46l_pre
1261    
1262    checkpoint46k_post
1263  o fixed the verification/global_ocean.90x40x15 experiment:  o fixed the verification/global_ocean.90x40x15 experiment:

1268   - fixed several errors and redundancies in the data file   - fixed several errors and redundancies in the data file
1269   - experiment uses looped cells   - experiment uses looped cells
1270   - added matlab directory with diagnostic scripts for plotting of output   - added matlab directory with diagnostic scripts for plotting of output
1271    
1272  release1_p5  o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1273  o import recent fix from MAIN branch:   - read AIM physics parameters from a file (data.aimphys)
1274    - use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S   - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1275    - change phiMin in exp1 (to agree with documentation)  
1276   from checkpoint45 to checkpoint45a_post:  checkpoint46j_post
1277    - specific exchange for X-slice domain (case Ny=1)  o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1278    - argument futureIter of S/R obcs_calc missing in  o move wVel computation at the end of the time step, in S/R integr_continuity
1279      exp4 & internal_wave /code  o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1280    - solve_for_pressure : set cg2d_x to zero where OBCS are applied  o update timeave pkg for wVel diagnostic.
1281   from checkpoint44f_post to checkpoint44g_post:  checkpoint46j_pre
1282    - fix surface correction term in multiDimAdvection  
1283      (affects plume_on_slope results  checkpoint46i_post
1284  o bug fix in packages_readparms (missing ALLOW_CALENDAR)  o Clean up AIM package (and keep the results unchanged):
1285  o bug fix in CG2D.h (correct array size for LETS_MAKE_JAM    include CPP_OPTION and use IMPLICT NONE in all routines ;
1286  o Adjoint-related bug fixes in kpp:    declare all the variables _RL ; use _d 0 for all numerical constants.
1287    - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix    use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1288    - kpp_routines: store of Rib avoids partial recomputation bug of TAF.  
1289  o added Eliassen-Palm flux hooks (dynamics,ini_fields)  checkpoint46h_post
1290  o removed unused TAF keys iikey, idkey (dynamics,thermodynamics)  o cleaned up the use of rhoNil and rhoConst.
1291  o flow directives:    - rhoNil should only appear in the LINEAR equation of state, everywhere
1292    - new for S/R do_the_model_io      else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1293    - enhanced for S/R checkpoint      and the dynamical equations are all divided by rhoConst
1294  o added Eliassen Palm flux controls to gradient check package  o introduced new parameter rhoConstFresh, a reference density of fresh
1295      water, to remove the fresh water flux's dependence on rhoNil. The default
1296      value is 999.8 kg/m^3
1297    o cleanup up external_forcing.F and external_forcing_surf.F
1298      - can now be used by both OCEANIC and OCEANICP
1299    checkpoint46h_pre
1300    
1301     Added code to convert surface volume flux (fresh water) into
1302     a mass flux when using P coordinates in the ocean (OCEANICP).
1303     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1304    
1305    checkpoint46g_post
1306    o Include a new diagnostic variable phiHydLow for the ocean model
1307      - in z-coordinates, it is the bottom pressure anomaly
1308      - in p-coordinates, it is the sea surface elevation
1309      - in both cases, these variable have global drift, reflecting the mass
1310        drift in z-coordinates and the volume drift in p-coordinates
1311      - included time averaging for phiHydLow, be aware of the drift!
1312    o depth-dependent computation of Bo_surf for pressure coordinates
1313      in the ocean (buoyancyRelation='OCEANICP')
1314      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1315        Theta, Salinity, and Pressure in the parameter list. This routine is
1316        presently contained in find_rho.F. This routine does not give the
1317        correct density for 'POLY3', which would be a z-dependent reference
1318        density.
1319    o cleaned up find_rho
1320      - removed obsolete 'eqn' from the parameter list.
1321    o added two new verification experiments: gop and goz
1322      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1323    checkpoint46g_pre
1324    
1325    checkpoint46f_post
1326    o Enable tangent linear (forward mode) gradient checks:
1327      - extended active file handling to g_... files
1328      - added TANGENT_SIMULATION to theSimulationMode
1329      - extended grdchk package accordingly
1330    o added tangent linear setup in verification/carbon/code_ftl
1331    o added adjoint setup in verification/front_relax/code_ad
1332    
1333    checkpoint46e_post
1334    o Added new equation of state -> MDJWF
1335      - EOS of McDougall et al., 2002, JAOT, submitted
1336      - caveat: the equation of state is only valid for a smaller (more
1337        realistic?) range of values than JMD95P/Z and UNESCO
1338      - added masks to the calculation of pressure in store_pressure
1339      - added more check values for density in check_eos (ini_eos.F), some of
1340        the old check values are out of the range of the MDJWF-eos, so don't
1341        expect perfect matches for those
1342    checkpoint46e_pre
1343    
1344    checkpoint46d_post
1345    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1346      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1347      case of pressure coordinates. eosType='JMD95Z' in
1348      combination with buoyancyRelation='OCEANICP' now causes an error.
1349    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1350      in find_alpha/beta.
1351    checkpoint46d_pre
1352    
1353    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1354      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1355    
1356    checkpoint46c_post
1357    o Changes necessary for ocean in p-coordinates
1358     -  Added new buoyancy relation = 'OCEANICP'
1359     -  Added new parameters = gravitySign (this used to be contained inside
1360        the factor dRdZ which I added when we first switched to R coordinates).
1361     X GM/Redi is not compatible (yet)
1362     X bottom drag and no-slip need to be debugged.
1363    checkpoint46c_pre
1364    
1365    checkpoint46b_post
1366    o Added new equation of state -> JMD95Z and JMD95P
1367      - EOS of Jackett and McDougall, 1995, JAOT
1368      - moved all EOS parameters into EOS.h
1369      - new routines ini_eos.F, store_pressure.F
1370    o Added UNESCO EOS, but not recommended because it requires
1371      in-situ temperature (see JMD95)
1372    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1373      unesco.f to be used with POLY3
1374    checkpoint46b_pre
1375    
1376    checkpoint46a_post
1377    o Added (atmospheric) pressure loading
1378      - new field in FFIELDS.h, etc...
1379      - new cpp flag ATMOSPHERIC_LOADING
1380    o Changed hFacC to _hFacC in calc_phi_hyd.F
1381    o Added SHORTWAVE_HEATING to some files for consistency

1410    
1411    checkpoint45d_post
1412    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1413    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
