5      ==============================      ==============================
6    
7    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
8      generate new output for test-experiment: aim.5l_cs.thSI
9    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
10     testreport accordingly
11    
12    checkpoint58e_post
13    o SEAICE_CGRID adjoint done
14    o R_STAR adjoint implemented.
15      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
16      * need to sort out init. of h0facc, etc.
17    o Make pkg/profile fully independent of ecco,cost, etc. stuff
18      to be able to use it in pure forward.
19    
20    checkpoint58d_post
21    o upgrade simple test-experiment to tutorial example:
22     step.1: duplicate the experiment and (step.2) will remove the old copy.
23      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
24      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
25      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
26      tutorial_global_oce_biogeo    <- copy of dic_example
27      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
28      tutorial_plume_on_slope       <- copy of plume_on_slope
29      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
30      tutorial_global_oce_optim     <- empty for now (David ?)
31      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
32     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
33    o correct a sign problem in cost_scat.F
34    o obcs and ptracers: fix boundary conditions for advections schemes
35      with larger stencil
36    o thsice adjoint: start
37    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
38      completeness
39    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
40      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
41    o ptracers adjoint:
42      * avoid extensive recomputatations
43      * fix missing re-init. of gptr (missed by TAF)
44    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
45      me to turn off the excessive output to STDOUT that this package produces
46    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
47      and add those terms in Vector-Invariant formulation.
48    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
49      if the control period (xx_hfluxperiod etc) is 0
50    o in profiles pkg, clean routines and fix details
51    o in ecco pkg, reading ssh data:
52      fix problem in case the model does not start at iter0=0
53    o fix mnc-pickup/restart for ptracers
54    o new package prifiles:
55      code to compute profile-based cost by Gael Forget
56      (modifs in ecco, ctrl, autodiff)
57    o Benign bug fix in initialization (spotted by M. Mazloff) of
58      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
59    
60    checkpoint58c_post
61    o adjoint: finish NLFS adjoint and provide reference output in
62      verification/global_ocean.90x40x15/results_ad_nlfs
63    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
64      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
65      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
66      with SEAICE_CGRID defined.
67    o move calendarDumps from "data" to "data.cal" and clean-up the code
68      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
69    o add useEXF & useCAL flags (for now, set in hard-coded way)
70    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
71      (were missing in NH mode, and wrong in quasihydrostatic mode).
72      waiting for Chris updated version of calc_gw to add those CALLs.
73    o fix bug in quasihydrostatic S/R ;
74      add a test for this option: global_ocean.90x40x15.qshyd
75    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
76      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
77    o add on/off flag useOffLine for package OFFLINE
78    o seaice:
79      - modify advection so that it works also on the C-grid
80      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
81        problem in multi-tile runs with C-grid
82      - add flags for clipping ice velocities and/or masking solver forcing
83      - fix drag (ocean on ice) formulation and a bug that caused noise in the
84        C-grid solver
85      - added a few comments to seaice_diffusion.F
86      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
87        are now exclusive)
88      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
89        required re-ordering the code a little:
90       + make DAIRN global variable (defined in SEAICE)
91       + move computation of the viscosities eta and zeta into a new separate
92         routine (because I need to recompute them in seaice_ocean_stress.F)
93    
94    checkpoint58b_post
95    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
96      update output.txt of exp. aim.5l_cs.thSI
97    o various mnc cleanups and improvements:
98      + shrink lookup tables by factor of ~4
99      + better error reporting when running out of lookup space
100      + able to handle longer path/file names (up to 500 chars)
101    o adjoint:
102      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
103      - TBD: "hidden" mom_vecinv recomp. in dynamics
104    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
105     (allow to differentiate between forcing components using new integer flags:
106      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
107     and add new flag to put Dissipation tendency out of Adams-Bashforth.
108    o ecco
109      - enable trend removal from SSH anomaly obs.
110    o adjoint
111      - a fix for PmEpR when #undef EXACT_CONSERV
112      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
113      - try to fix "hidden" recomp. in forward_step for NLFS
114        (NLFS seems broken sometimes after I checked it in)
115    o seaice:
116     - add c-grid version of the dynamic solver:
117       + three new routines that are the c-grid substitute lsr, dynsolver
118         and ostres
119       + put a few fields that were local to dynsolver into global common
120         blocks, so that I can move the computation of stresses etc into
121         seaice_lsr (saves coding but may break the adjoint).
122     - replace more hardwired parameters by runtime parameters
123     - add ice masks that mask the rhs of the implicit solvers where there
124       is no ice (commented out in seaice_dynsolver, because i am not sure
125       if this works properly), eventually this should replace the clipping
126       of ice velocities in seaice_dynsolver to +/-40cm/s.
127    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
128      include it only where its needed
129    o move balancing of fluxes before the call of external_forcing_surf
130    o seaice:
131      - correct units of turning angles (now they are really in degrees)
132      - move computation of GWATX/Y out of main routine into dynsolver
133      - initialize GWATX/Y in seaice_init
134    o Apply mask on Fresh-Water flux (needed for SSH forcing).
135      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
136    o seaice: add runtime flags for turning angles (default to zero)
137    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
138      and trend from exf forcing and ctrl control adjustments
139    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
140      (since checkpoint57x_post)
141    o change the default rotation period to 86164.s = the Earth rotation
142    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
143      and based on a reference stratification. Tested within hs94.cs-32x32x5.
144    o seaice advection: add code for choosing between the default (2nd order
145      central differences) and multiDim advection schemes provided by
146      pkg/generic_advdiff
147    o seaice:
148      - removed all references to SEAICE_GRID.h fields from
149        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
150        (cubed-sphere configuration will change a little)
151      - grid computations in seaice_init are obsolete now.
152      - cleaned up code a little so that is easier to read (hopefully).
153      - added new (better?) discretizations of default advection and diffusion
154        (turn on with SEAICEuseFluxForm)
155      - replace 1 in 3d global fields by kSurface in growth.F
156      
157    checkpoint58a_post
158    o seaice:
159      - bug fix in advect.F
160    o shelfice:
161      - separate shelfice load anomaly from pload (breaks with time
162        dependent forcing), => introduce constant field shelficeLoadAnomaly.
163        Its default is 0., but it may be computed more cleverly from (unknown)
164        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
165        done offline. A good approximation of the pressure load anomaly is
166        necessary to avoid large initial adjustment processes underneath
167        deep-reaching shelfice.
168      - small fix in ISOMIP shelfice_thermodynamics
169      - add more sophisticated thermodynamics of Hellmer (1989), this is
170        now the default
171      - give a few constants more intuitive names
172    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
173      if bulk formulae are used in long integration (especially EmPmR). Turn
174      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
175      if balancePrintMean, the imbalance that is substracted is printed to
176      STDOUT.
177    o fix bug (typo) in obcs_apply_eta.F
178    o add a new package shelfice which enables us to model the circulation
179      underneath shelf-ice with draughts of hundreds of meters.
180     - works
181     - to do: + include improved thermodynamics
182              + check whether kSurfC (from model/inc/SURFACE.h) can be used
183                instead of new field kTopC
184              + can we use topoFile, Ro_surf and existing code in ini_depth.F
185                instead of new field R_shelfIce and new code in ini_depth.F
186                and ini_mask_etc.F?
187              + adjust vertical mixing schemes?
188    o seaice pkg:
189     - add a cpp-flag to include a simple formula for a salinity dependent
190       freezing point of sea water at the surface
191     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
192       meridional stresses are now different (and hopefully correct)
193    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
194       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
195       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
196    o pkg/diagnostics: add options and parameters for regional-statistics
197       diagnostics ; define regions by reading a region-mask from a file
198       (might add other options later)
199    o pkg/bulk_force:
200     - add option and parameters to use AIM surface-flux formulae.
201     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
202       others forcing fields (defined in PARM05, parameter file "data") are loaded
203       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
204     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
205     - use the right EXCH call for uwind,vwind (to work on CS-grid).
206     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
207       and parameters (note: calcWindStress replaces .NOT.readwindstress).
208     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
209    
210    checkpoint58
211    o add "--embed-source" option to genmake2 which, when the supporting
212      tools can be compiled (as determined by genmake2) will turn on the
213      embed_files package which then embeds the entire MITgcm source code
214      (*.[fFhc] + Makefile) used for the build within the executable
215      - requested by CNH but off by default
216      - adds a paltry <9MB to the mitgcmuv executable in most cases
217      - only writes the output when useEMBEDSRC in eedata is true
218    o clean up 3-dim. relaxation codes:
219      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
220      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
221      * Thanks to Tom Haine for testing!
222    
223    checkpoint57z_post
224    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
225      affects output (@ truncation level) of exp. plume_on_slope ; updated.
226    o fix the pickup behavior for obcs in combination with ptracers
227    o fix a bug in ptracers_external_fields_load
228    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
229      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
230    o transfered surface NH pressure to eta field (if exactConserv).
231    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
232         and update lab_sea output.txt file.
233    o completing 3-dim. relaxation code: additional term
234         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
235      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
236      * At compile time, in "EXF_OPTIONS.h" set
237          #define  ALLOW_CLIMTEMP_RELAXATION
238          #define  ALLOW_CLIMSALT_RELAXATION
239      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
240          tauThetaClimRelax3Dim = 15552000.0,
241          tauSaltClimRelax3Dim  = 15552000.0,
242      * 3 cases:
243          1) Use a constant-in-time 3-dim. field
244          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
245          3) Real-time relax. to time-evolving prescribed field
246    o Adding Laplacian-type smoothness constraint on
247      initial and boundary (forcing) controls (ic, bc)
248      * enable at compile-time via
249        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
250      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
251      * Absolute scale somewhat unclear so far
252      * no area weighting was included since no other cost term does so far
253    
254    checkpoint57y_post
255    First step for a NLFS adjoint
256    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
257    o new init. routines for calc_r_star, calc_surf_dr
258    o still need to deal with ini_masks_etc
259    o testreport seemed happy
260    checkpoint57y_pre
261    
262    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
263    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
264    o add new offset feature to offline pkg (plus minor cleanup)
265    o cfc fixes for final year of integration
266    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
267      be in GCHEM_OPTIONS).
268    
269    checkpoint57x_post
270    o fix testreport Pb in multiple test experiment.
271    o cleanup our namelist syntax in verification:
272      - make it more F95 standards compliant (some work still needed)
273      - allows the vast majority of our tests to work with gfortran
274    o Non-Hydrostatic:
275     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
276     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
277    o Allow to apply AB on T,S rather than on AB(gT,gS):
278     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
279     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
280       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
281     - need a "clever" read_pickup to restart from the other AB formulation
282    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
283    o remove some unused variables (reduces number of compiler warnings)
284    o adjoint
285      * Disable useVariableViscosity for adjoint for time being
286        (there are a number of extensive recomputations)
287      * Initialize certain variables needed for adjoint
288    
289    checkpoint57w_post
290    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
291                 fix the singleCpuIO RS version of MDSWRITEFIELD
292       and add a WARNING if using globalFiles=T with multi-processors.
293    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
294      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
295    o tracer advection scheme:
296      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
297       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
298       was not very convenient).
299      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
300       (further tests needed for the implicit DST & Flux-Limiter schemes).
301    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
302      and sRef for convenience, handy, when you want to initialize
303      ptracers in a large domain with a constant non-zero value. Also,
304      untangle ptracers_init.F a little.
305    
306    checkpoint57v_post
307    o change dome exp. to use variable viscosity in side-drag terms.
308    o remove all the files from the cfc_offline test since they are now
309      incorporated into tutorial_cfc_offline which has been producing
310      identical results for a few days of testing
311    o add new parameter: sideDragFactor to enable half-slip-side BC
312      and change side-drag S/R to use viscosity from mom_calc_visc
313      (can switch back by setting sideDragFactor=0.); affects results at
314      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
315       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
316    o vorticity & strain are now computed without masking, to account for
317      no-slip-side BC in variable viscosity calculation ; mask is applied
318      anyway later on, before computing advection/coriolis terms.
319    o modify exp4 to test new obcs support for reading from external files
320      and for passive tracers
321    o fix behavior of ptracers_monitor when monitor output is written to a
322      netcdf-file; still not independent of monitor.F (writes in the same
323      file).
324    o change default value of tRef (put a uniform, meaningful value for ocean
325      & atmos) and initialize sRef (was missing, as Martin mentioned).
326    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
327      to be proportional to enstrophy dissipation length.  Thus,
328       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
329      This is now consistent with Smagorinsky and with the manual.
330    
331    checkpoint57u_post
332    o OBCS and PTRACERS: add open boundary support for passive tracers
333      - either use homogenous (pseudo) v.Neumann conditions or prescribe
334        OB-values from file; this is not different from the way theta and salinity
335        are treated
336      - however, Orlanski-radiation conditions are not supported, and the model
337        will stop if you use pTracers and Orlanski at the same time.
338      - beefed up the rountine obcs_external_fields_load: now only those open
339        boundary values are overwritten with values from files for which there
340        are really files, otherwise the OB-fields remain untouched. This makes
341        it possible to use different OBs at different ends of the domain (as
342        with EXF)
343    o reduce number of exch calls in shap_filt (s2).
344    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
345      truncation level) 4/5 MLAdjust test results (11&12 digits match).
346    
347    checkpoint57t_post
348    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
349    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
350      same truncation, independent of the face number: affects affects several
351      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
352    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
353      note that biharmonic viscosity + no-slip was not tested in any experiment.
354    o fix bug in non-linear free-surf side-drag ; generate new output for
355      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
356    o make mnc honor the writeBinaryPrec flag for most kinds of output
357    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
358    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
359      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
360    o add brackets in multi-terms sum to get same truncation, independent of
361      the face number (manage to get exactly same value of gU,gV at the cs-edge)
362      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
363    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
364      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
365      a maximum grid-scale Reynolds number.  Also, changes all length calculations
366      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
367      Suggested values of viscosity parameters found in mom_calc_visc.
368      Many new viscosity diagnostics available.
369    
370    checkpoint57s_post
371    o Add clearing-house for viscosity calculations, mom_calc_visc and
372      correct numerous bugs in LeithD and Smagorinsky discretizations.  
373      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
374      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
375      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
376      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
377      The Strain-Tension form is now called with useStrainTensonVisc=.true.
378      ViscAhStrain and viscAhTension are now retired.
379    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
380    o In response to JMC's bug report, genmake2 now ignores any soft-links
381      that it finds in the *current* directory when searching for files.
382      Soft-links found in any other source directories will still work as
383      they did before.
384    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
385      a C routine to unlimit the stack size
386    o mnc-ify pkg/aim snapshot vars
387    o mnc-ify pkg/land as requested by Daniel
388    o various changes to mnc including:
389      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
390      - output can now be grouped so that all files within a group
391          change the ITER portion of their names in lock-step together
392      - can now read ("global") PER-FACE (in addition to PER-TILE) files
393          and works with both EXCH1 and EXCH2 (but needs more testing)
394      - writing works for all verification test cases w/ g77 on Linux
395    
396    checkpoint57r_post
397    o make MNC variable initialization happen earlier
398    o add diagnostics for (almost) each term of the momentum Eq.
399    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
400    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
401    o remove MINIMAL_TAVE_OUTPUT option ;
402      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
403    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
404      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
405    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
406    o add time-dependent SST, SSS control
407    o cost terms in ecco/ modularized (new cost_generic.F)
408    o cost_averages routines are modularized (new cost_averagesgeneric.F)
409    o new infrastructure for seaice model vs. obs misfits in seaice/
410      * driver from the_main_loop.F is seaice_cost_driver.F
411      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
412      * gradient check in Exp. 6a of natl_box_adjoint/
413    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
414      (see README file)
415    
416    checkpoint57q_post
417    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
418    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
419      - bug was reported by Jean-Michel and Ian Fenty
420    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
421      update exp. cpl_aim+ocn output.
422    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
423      Needed for high-res. runs with large global files
424      to be able to limit tapelev size
425    o Changed some tests for adjoint:
426      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
427      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
428      * global_ocean.90x40x15/ back to default 3-level checkpointing
429    o Modifications to enable scripted COMMON to MODULE conversion
430      * verification/OpenAD/code/ has necessary scripts and description;
431      * converts, compiles and runs successfully;
432    
433    checkpoint57p_post
434    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
435    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
436      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
437    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
438    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
439      (was already the case for dissipation with mom_vecinv,
440       and also the case for grad.PhiHyd when staggered-timeStep)
441      This will allow to put dissipation out-off the AB time-stepping.
442     Unfortunately, affects truncation error. Update output of exp. that "fails"
443      (cg2d matching number) and leave the others for later: front_relax(10),
444      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
445      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
446    
447    checkpoint57o_post
448    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
449      (2) its ready to be documented during the 20050801 DocFest
450    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
451      for ideal_2D_oce and lab_sea on linux_ia32_g77
452    o set to #undef CTRL_SET_OLD_MAXCVARS_30
453      in global1x1_tot/code_seaice_adj to access indices 32, 33
454      (worth another tag)
455    
456    checkpoint57n_post
457    o adding precip control xx_precip 32
458    o adding swflux control xx_swflux 33
459    o Replacing 10 forcing penalty cost routines by 1 generic.
460    o Implementing partitioning in time-mean and variable adjustment
461      for atmos. state.
462    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
463    o in natl_box_adjoint:
464      * updated exp 1 to 10
465        (but does not have time-mean vs. variable split results yet)
466    o updated global1x1/*_seaice_adj/
467      to incorporate latest changes
468    o enable useSingleCpuIO for mdsio vector routines
469      (applies in particular to tapelev I/O)
470    o removed inefficient K-loop in all active_file*control*.F
471    
472    checkpoint57m_post
473    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
474      and advect_cs (use EXCH-2 and standard cs-32 grid files).
475    o pkg/exch2: filling of face-corner halo regions is optional
476      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
477    
478    checkpoint57l_post
479     tag before updating tutorials (pre-release-2)
480    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
481       for output and interpolation of input fields onto model grid)
482    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
483       Affects results of exp. rotating_tank ; update output.txt.
484    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
485          and taking the square quantity and/or using a fraction-weight field.
486    o fix aim_diagnostics_init.F mate numbers.
487    o add mnc output capability to diagnostics/diagstat and update
488      our cvsignore files for the ACSII output generated
489    
490    checkpoint57k_post
491    o lab_sea now uses diagnostics package and provides a suite of
492      new EXF diagnostics output.
493    
494    checkpoint57j_post
495    o exf
496      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
497        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
498        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
499      * extended diagnostics output
500        - now includes all EXF variables
501        - hs, hl moved to common block
502        - separate S/R for diagnostics, called after ctrl vector is added
503        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
504        - EXFqnet contains true Qnet (i.e. includes qsw)
505      * updated verif. lab_sea, global_with_exf
506      * Rearranging hflux (exf_mapfields -> exf_getforcing)
507        to ensure that diagnostics sees a true EXFqnet
508    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
509    o diagnostics pkg: change pointers so that 1 diagnostic can be used
510      several times with different frequencies.
511    o mnc-ify the thsice package as requested by Daniel Enderton
512      - the monitor--MNC output needs work
513      - many attributes need to be added (most are currently blank)
514    o mnc-ify theaim_v23 package as requested by Daniel Enderton
515      - many attributes need to be added (most are currently blank)
516    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
517    o add Sadourny like discretization to the 4th.O vorticity advection scheme
518    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
519      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
520         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
521    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
522     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
523    
524    checkpoint57i_post
525    o Diagnostics package was changed: diagnostic allocation is now deactivated
526      by setting an empty file name in the namelist (used to be by setting 0 frequency)
527    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
528      add 1rst Order upwind vertical Shear.
529    o add a quick fix for A/B checkpointing in OFFLINE mode
530    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
531      end-run around the C/Fortran linking horror in eesup/src/timers.F
532    o added pkg/runclock: allows user to terminate run based on wall clock
533    o added non-hydrostatic scaling parameter: nh_am2
534    o pkg/my82: futile attempt to make results compiler-independent by adding
535      some "_d 0", etc. no effect.
536    o for mnc output, fill the 'T' coordinate var with myTime and create a
537      separate 'iter' variable for iteration count
538    o pkg/diagnostics:
539      add new capability: output of Global/Regional & per-level statistics ;
540      tested against monitor output (including land & thSIce) on various exp.
541    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
542    
543    checkpoint57h_done
544      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
545      data.diagnostics, data.gchem, data.ptracers) is done.
546    
547    o pkg/diagnostics: prepare for Global/Regional statistics.
548      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
549    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
550      and rename it: DIFFERENT_MULTIPLE
551    
552    checkpoint57h_post
553    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
554    o pkg/diagnostics: change output frequency, now in seconds (instead
555      of Nb of iterations). This requires to change data.diagnostics.
556    checkpoint57h_pre
557    
558    o in mnc, let the user create the output dir if both mnc_outdir_date
559      and mnc_outdir_num are false
560    o add fflags() to pkg/diagnostics which allows one to specify, on a
561      per-file basis, the file precision [default behavior is unchanged]
562    o added diagnostics to pkg/kpp, including computation of mixed layer
563      depth based on a temperature/density criterion
564    o updated verification/natl_box to test the new pkg/kpp diagnostics
565    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
566    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
567    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
568      not mnc -- this mistake was found by JMC and is now corrected
569    
570    checkpoint57g_post
571    o add Adams-Bashforth 3rd Order time stepping:
572      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
573      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
574    checkpoint57g_pre
575    
576    o make lambda[Theta,Salt]ClimRelax spatially varying
577      (default remains spatially uniform constant based on tau)
578    o added new control variables
579      * init. uVel, vVel, etanN
580      * lambda[Theta,Salt]ClimRelax
581    o separate masks used for ctrl_pack/unpack 'from write_grid' output
582      (suggested by G. Forget)
583    
584    checkpoint57f_post
585    o add parameter "baseTime" = model base time = time at iteration zero
586      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
587      account for baseTime shift
588    o move Coriolis arrays from PARAMS.h to GRID.h
589    checkpoint57f_pre
590    
591    o mnc-ifying the seaice package
592    o introduced an alternative length scale calculation for use in the limiting
593      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
594    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
595    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
596      as well as grad(vort3).  Made it compatible with both approximate form
597      for the cubed sphere and full form of these gradients.  Added flag
598      useFullLeith to select between approximate and full form.  
599    o add "d0" in getcon.F to reduce differences between compilers/platforms
600      update output.txt of exp. fizhi-gridalt-hs
601    o change port_rand funtion to allow to set the seed.
602    o fix obscure MNC bug involving conversion between reals and integers
603      - it caused no problems with certain (eg. gcc, ifc) compilers but the
604        new version is now more standards-compliant
605    o adjoint-related modifications
606      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
607      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
608      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
609    
610    checkpoint57e_post
611    o Adding eddy stress controls a la Ferreira et al.
612    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
613    
614    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
615      update output.txt of exp. fizhi-gridalt-hs
616    o add more "Z" dimensions and associated coordinate vars to MNC
617    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
618    o parameter calendarDumps: when set, approximate months (30-31 days) and years
619      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
620      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
621      months and years.  Requires pkg/cal.
622    o diagnostics: add pickup functionality
623      - off by default for backwards compatibility
624      - current version only uses MDSIO -- MNC will be added
625    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
626    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
627    
628    checkpoint57d_post
629    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
630    o modify verification/ideal_2D_oce so that it tests the creation of mnc
631      output from the diagnostics package
632    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
633    o make genmake2 more portable by using ".$FS" instead of ".f" for more
634      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
635    o add coordinate variables to the MNC output from the diagnostics package
636    o change MNC-flags default value: true when useMNC=TRUE
637    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
638      the ability (off by default) to read the grid information using MNC
639    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
640    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
641    o do snap-shot diagnostics at the middle of the time-interval (instead of
642      at the end).
643    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
644      new test for AIM with thSIce + slab-ocean
645    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
646    o move state variable diagnostics to the beginning of the time step ;
647      (note: still needs some work specially for snap-shot diagnostics)
648      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
649    
650    checkpoint57c_post
651    o Change testing option (-ieee) to get closer agreement between g77 & ifort
652    o generate new output.txt files on faulks with g77 & the new -ieee option
653    checkpoint57c_pre
654    
655    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
656      update output.txt of exp. global_ocean.90x40x15
657    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
658      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
659    o add saltFlux(+File) forcing capability with periodicExternalForcing
660    o allow to use pkg diagnostics for GM-Redi & ThSIce output
661    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
662    o improvements for the MNC output from DIAGNOSTICS:
663      - correct handling of the unlimitied dimension
664      - all dims now have associated coordinate variables
665      - variables located at U, V, and Corner ("Z") points are now written
666        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
667        *all* data points are output
668    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
669    o added pkg/seaice/seaice_monitor.F
670    o mdsio_readfield.F can now read files visible only to master MPI process.
671    o pkg/seaice: some test code for ice-modified ocean stress
672    o exf_getffields interpolation defaults to bilinear for all scalar forcing
673      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
674      spurious negative numbers for precipitation and humidity.  Will cause
675      some small numerical differences for integrations using pkg/exf/exf_interp.F.
676    o pkg/ctrl/
677      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
678        May be enabled via doPackDiag
679      *  introduce z-scaling of
680         + gradient (doZscalePack) and
681         + control (doZscaleUnpack)
682    o pkg/mdsio/
683      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
684      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
685    
686    checkpoint57b_post
687    o simplify options in diagnostics_fill arguments (remove weird combinations)
688    o fix MNC coordinate variables so that they now contain per-face index
689      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
690      general, EXCH2 grids are only aligned to a "local" coordinate system
691    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
692    o Implement instantaneous output within pkg diagnostics:
693      setting a negative frequency in data.diagnostics produces
694     "snap-shot" output (as opposed to time-average if freq > 0)
695    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
696      NOTE: change ptracer diagnostics name: use 2 characters to work with
697            more than 9 tracers. Add also diagnostics of advect & diffus flux.
698    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
699      becomes the coordinate variable for the 'T' dimension
700    o add CF-style coordinate variables to MNC
701      - just a first cut:  numbers are meaningless on the cubesphere and
702        missing along the T axis but otherwise it works!
703    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
704    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
705    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
706      this is based directly on what the model compute, so that the content of
707      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
708    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
709    o clean up build options files for SunOS, in particular
710      - remove -traditional from xmakedepend
711      - change -xarch=v9 to -xarch=native for f77
712      - restore use of make (not gmake)
713      - add CC=gcc if using g77
714    o changes per discussion of AM, JMC, & EH3 today:
715      - move redundant "grid" variables out of "state" -- in preparation of
716        creating proper CF-style coordinate variables and in recognition
717        that any/all grid variables can be easily copied (eg. w/NCO) from
718        the grid files into any of the other NetCDF files
719      - *always* output grid variables with MDSIO (this will eventually be
720        changed)
721      - output MNC grid file if useMNC is true
722    o every instance of _END_MASTER() has been found and replaced with
723      _END_MASTER( myThid ) in order to satisfy certain picky Sun
724      preprocessors
725    o re-arrange diagnostics pkg initialisation:
726     - allow each package to extend the available diagnostics list
727     - add some checking and fix small problems (multi-threaded, ...)
728     - new S/R diagnostics_fill (replace fill_diagnostics):
729       look through the short list of active diag. (instead of the long list)
730       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
731    
732    checkpoint57a_post
733    o this set of changes restores TAMC compatibility
734      tested for global_ocean.90x40x15 adjoint on trough
735      (what a pain)
736    
737    checkpoint57a_pre
738    o some modifs in tools/build_options for sunos
739    o call ctrl_pack for ctrl at end for optimcycle=0
740    
741    checkpoint57
742    o add horizontal bi-harmonic viscosity for vertical velocity
743      - new parameter viscA4W (defaults to viscA4)
744      - affects only non-hydrostatic code
745      - to be done: no-slip lateral boundary conditions
746    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
747    o implement Implicit Vertical advection for pTracers
748    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
749      (implemented also for implicit vertical diffusion & advection)
750    o OBCS: extend application of tracer open boundary conditions
751      to a strip beyond the boundary of width Olx/Oly
752    o add call monitor to TAF set of required calls (flow directives)
753      and include in natl_box_adjoint
754    o untangle a few ifdefs related to cost, ctrl, autodiff
755      untangel a few ALLOW_ECCO_OPTIMIZATION
756    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
757      (theta2, salt2 in ecco_cost_weights)
758    
759    checkpoint56c_post
760    o OBCS as control variables
761      - update ctrl_ad_diff.list, obcs_ad_diff.list
762      - remove balance of obcs controls from default
763      - fix index bug nobcs in ctrl_init
764      - fix dummy fields filen in ctrl_pack
765      - add dummy weights for obcs
766    o lsopt: comment out fort.94 output
767    o optim:
768      - remove unnecessary header files
769      - adjusted namelists
770      - add xerbla.F to Makefile
771    o exf:
772      - multiple modifications of exf_check_range
773      - unit change in exf_init_runoff from [m/year] to [m/s]
774    o mdsio:
775      - i/o-vector change debugLevel from debLevA to debLevB
776    
777    checkpoint56b_post
778    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
779      is called from DO_THE_MODEL_IO
780      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
781      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
782      - clean up PTRACERS_WRITE_TIMEAVE a little
783    o add another verification experiment that tests both the cfc-pkg and
784      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
785      reactive tendencies treated inline with regular timestepping
786    o testreport previously did a lousy job of comparing small numbers, so
787      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
788      implemented in the little c-progam tmp_cmpnum.c which is embedded in
789      testreport.
790    o ptracers_monitor: bug fix for MPI
791    
792    checkpoint56a_post
793    o GCHEM: finish reorganizating the package
794      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
795        (introduces another 3D-array for each passive tracer, but only if
796        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
797        gchemTendency is not needed because the timestep is done separately)
798      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
799      - GCHEM is now---more or less cleanly---separate from PTRACERS
800      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
801        so clear to me how that should be done in a general way.
802    o CFC: improve formatting of output in CFC_ATMOS
803    o PTRACERS:
804      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
805        that ALL experiments with ptracers enable can be checked. This makes
806        GCHEM_MONITOR obsolete.
807      - include a runtime parameter PTRACERS_monitorFreq that defaults to
808        monitorFreq
809      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
810    o add PTRACERS (PTR0[1-5]) to testreport output
811    o exf_check_range:
812      * default changed to .TRUE.
813      * will check values for niter0 if debLevA, every timestep if debLevB
814      * STOP in exf_check_range if 'out of range'
815      * range chosen generous to allow for potential extema
816      TBD: a version with stricter range
817           permitted range would be runtime parameters
818    o GMredi:
819      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
820      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
821      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
822    o GCHEM:
823      - move call to GCHEM_FORCING_SEP, so that it is now called before
824        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
825      - introduced a useGCHEM runtime flag and applied it everywhere.
826      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
827        this flag is now only visible within GCHEM-pkg routines.
828      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
829        be replaced by a 3D array that is computed before thermodynamics; for
830        this, the tracer ID iTracer had to be included into the parameter list
831        of ptracers_forcing
832      - set up forward_step to call gchem_forcing, that will replace
833        gchem_forcing_int in ptracers_forcing
834      - cleaning up
835    o small cleaning of exch2: remove files that are also in eesupp/src
836    
837    checkpoint56
838    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
839    o mnc: cleanup "full" files--fixes out-of-memory problem
840    o ECCO-GODAE
841      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
842      * fully merged and updated from SIO code
843        windstress sign change affects
844        - exf_inscal_[u/v]stress
845        - sign of xx_tau[u/v] adjustments
846        - signs in cost_scat
847      * ctrl_get_gen: avoid update of tau[u/v] for first few days
848      * natl_box_adjoint updated and compressed
849      * 2-level checkpoint switch added
850        (tested in EXP. 1 of natl_box_adjoint)
851      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
852    o SVD
853      * first complete, non-hacked version for SVD calculations
854      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
855        performed via direct access files admtlm_vector.it????
856        (via ctrl_[un]pack)
857      * optimcycle is used for ARPACK iteration counter
858        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
859      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
860        and add linear transforms where necessary
861      * controls are initial/final SST, SSS (can be extended; need to check
862        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
863    o mdsio: filename info to both stderr, stdout
864    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
865      from sign change
866    
867    checkpoint55j_post
868    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
869      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
870    o add consistent build directories and .cvsignore files to verification
871    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
872    o make all subroutines 30 or less characters in length for certain older
873      compilers to work (a thorough search only turns up two routines in
874      pkg/ptracers)
875    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
876      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
877    
878    checkpoint55i_post
879    o change arrays for total vertical diffusivity (2.D if explicit,
880      3.D if implicit) ; each ptracer uses its own background value.
881    o added mnc/NetCDF output capability to ocn_compon_interf
882      - added bits to verification/cpl_aim+ocn so that it can run on
883        ITRDA and other clusters without the mpirun "-wd" option
884    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
885      configuration
886    o give MNC the ability to create additional files rather than
887      exceeding a specified file size limit "MNC_MAX_FILESIZE"
888      - the default is just less than 2GB which is a practical limit
889        on many systems
890    o Compute the non-local term using either KPP vertical diffusivity (=default)
891       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
892    
893    checkpoint55h_post
894    o add verification test "vermix"
895    o remove all the *_ioinc flags and replace with the single global
896      outputTypesInclusive flag
897    o allow to set a vertical profile of vertical diffusivity for T & S
898    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
899    o useMNC moved from data.mnc to data.pkg
900    
901    checkpoint55g_post
902    o Renaming carbon AD experiments to comply with testreport conventions
903    o Updating adjoint of Held-Suarez hs94.1x64x5
904    o Fixing directives for non-ECCO forward_step, after ECCO directives
905      have been fixed to avoid recomp. of do_oceanic_phys
906      Works well for global_ocean.90x40x15,
907      but recomp. issue remains for carbon
908    o Updating adjoint output for natl_box_adjoint after
909      pkg/ecco has been modified (see taga c55d_post)
910    
911    checkpoint55f_post
912    o rename to timeave_init_fixed
913    
914    checkpoint55e_post
915    o some delicate re-shuffle of store directives to avoid one
916      extra call of do_oceanic_physics
917      affects ecco_the_main_loop.F, do_oceanic_physics.F
918      checkpoint_lev1_directives.h
919    o NB: this may break global_ocean adjoint temporarily,
920      but it is clear how to fix it. Will do later, need this now.
921    
922    checkpoint55d_post
923    o ECCO specific cost function terms (up-to-date with 1x1 runs)
924    o ecco_cost_weights is modified to 1x1 runs
925    o modifs to allow observations to be read in as
926      single file or yearly files
927    o enable to read exf forcing fields as either
928      single file or yearly files (flag useExfYearlyFields)
929    checkpoint55d_pre
930    
931    o switch between 2-level and 3-level checkpointing
932    o add ability of MNC to write local and "partial" (eg. 2D slices where
933      the full 3D field is never actually stored) arrays to NetCDF files
934      with the correct (that is, the complete multi-dimensional) set of
935      array indicies
936      - used in mom_vecinv() to write the diagFreq output
937      - tested (demonstrated) in verification/aim.5l_cs
938    o further mnc-ification
939      - add verification/lab_sea to the list with mnc setups
940      - fix undefined mnc v-names in cd_code
941      - add kpp to mnc output (both snapshot and timeave)
942    o non-hydrostatic code
943      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
944        in calc_gw.F
945      - defaults to viscAh
946      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
947        friction or Leith) in non-hydrostatic mode, as long as there is
948        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
949    o pkg/cost
950      extend simple cost functions to treat time mean quantities
951      (T,U,V) via cost_accumulate_state from cost_tile
952    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
953        be 2 times larger than the minimum size the advection scheme requires.
954        now get a perfect conservation of salt in advect_cs test-exp (updated)
955    o GGL90 (Gaspar's TKE mixed layer)
956      - add horizontal diffusion of TKE, requires exchanges in
957        do_fields_blocking_exchanges, horizontal diffusivity is zero by
958        default. In OPA there is no horizontal diffusion of TKE but the
959        mixing coefficients are computed from a horizontal average of TKE of
960        6 points or so. I think that diffusion has a little more physical
961        justification.
962      - clean up ggl90_calc in the hope of reducing memory usage (this hope
963        was in vain)
964      - mask tke-variable in ggl90_init
965    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
966    o fix biharmonic diffusion on CS-grid.
967    o more obcs stuff
968      - added obcs_external_fields_load as an alternative to the EXF-pkg option
969        for reading boundary values. This routine is called from
970        obcs_prescribe_read
971      - updated obcs_check
972      - changed sponge layer relaxation parameter units for days to seconds
973      - turned off sponge layer by default
974      - changed argument list of OBCS_CALC to myTime+deltaTclock
975      - fixed about 35 bugs in obcs_external_fields_load
976    
977    checkpoint55c_post
978    o obcs stuff
979      - new runtime flags useOBCSprescribe, useOBCSbalance
980      - re-arranged obcs_calc
981      - moved exf_getobcs to obcs_prescibe_read
982        obcs_prescibe_read is called after ORLANSKI stuff
983        and independent of it (executable can contain all).
984      - updated obcs_check
985      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
986        These may be necessary only if tangential velocities are
987        prescribed at OB, not sure, needs testing.
988    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
989      which simplifies the calls and passes the ifc check-bounds test
990    
991    checkpoint55b_post
992    o add a 2D scalar, Z location, exchange_2 routine.
993    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
994      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
995      affects advect_cs results (for the wrong reason): update output.txt
996    o use a more standard discretization for biharmonic viscosity ;
997     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
998      affects results of dome set-up: update output.txt
999    o fix gad_advection.F (CubedSphere part), back to version 1.23
1000    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1001    
1002    checkpoint55a_post
1003    o merged code to
1004      * prescribe/read time-dependent open boundaries
1005        (works in conjunction with exf, cal)
1006      * sponge layer code for open boundaries
1007      * each boundary N/S/E/W now has its own CPP option
1008        (healthy for the adjoint)
1009    
1010    checkpoint55
1011    o up-to-date adjoint of previous breaks
1012      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1013      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1014      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1015      - carbon: * remove tr1-related adjoint verification
1016                * add ptracer as control variable
1017    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1018      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1019    
1020    checkpoint54f_post
1021    o in verification/carbin/ remove experiment related to
1022      ALLOW_PASSIVE_TRACER (array tr1 etc)
1023      code_ad/ input_ad/ results_ad
1024    
1025    o add two new packages
1026      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1027        + subject to optimization (memory)
1028      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1029        + subject to reordering (many GOTOs in the original code)
1030        + so far opps is called for every (i,j) point, and then operates in
1031          the vertical; one may want to reorder the scheme in order operate in
1032          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1033          fields)
1034    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1035      - all verification tests compile and run with linux_ia32_g77
1036      - defaults are compatible with current input files--nothing
1037        should change if you were not previously using MNC
1038      - MNC output has been added in numerous places (eg. timeave)
1039        but there are still a few writes not yet do-able with MNC
1040        (this is in progress)
1041      - flags now allow for either/or/both use of MDSIO and MNC and
1042        documentation will soon follow
1043      - numerous small formatting cleanups for ProTeX
1044    o add version info (via BUILD_INFO.h) to MNC and stdout
1045    
1046    checkpoint54e_post
1047    o add two new packages
1048      - pp81 (Packanowski and Philander, 1981), Richardson number and
1049        stratification dependent mixing
1050      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1051      - these scheme operate in a similar manner as KPP (without ghat, of
1052        course), however there is only one diffusivity that is used for both
1053        temperature and salinity (and passive tracers)ç
1054    o add offline package
1055    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1056      provided by Stephanie Dutkiewicz
1057    o genmake2: add ability to search for C compilers and cleanup test output
1058      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1059    
1060    checkpoint54d_post
1061    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1062    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1063      leading to additional shift by 5 days each year of integration
1064       (i.e. leading to considerable offset over the years)
1065    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1066    o start with no AB and no initial filtering (staggerTimeStep):
1067      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1068    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1069      (external loading & cpl import/export stay in forward_step.F)
1070    o update coupling interface to work with new staggerTimeStep
1071    o change MDSIO ptracers_pickup.
1072    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1073    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1074    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1075    
1076    checkpoint54c_post
1077    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1078      this affects (truncation error) output.txt of test-exp:
1079       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1080    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1081    o change Qnet to always be the net heat flux, (+upward).
1082      affects (truncation error) output of natl_box exp.: updated
1083    o define the max number of passive tracers in PTRACERS_SIZE.h
1084    o start to test mnc routinely in exp0
1085    o add sea-ice loading (sIceLoad) as a new forcing field.
1086    
1087    checkpoint54b_post
1088    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1089       impressive on Altix and Opteron systems)
1090    o diagnostics can now write NetCDF files through the mnc package
1091    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1092    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1093    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1094      affects (truncation error) output of lab_sea & natl_box exp.: updated
1095    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1096    
1097    checkpoint54a_post
1098    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1099    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1100    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1101    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1102      + internal_wave (shift in writing cg2d_ini_res)
1103    checkpoint54a_pre
1104    
1105    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1106      - modified verification/lab_sea and natl_box_adjoint accordingly
1107    
1108    checkpoint54
1109    checkpoint53g_post
1110    o prepare splitting of thermodynamics: store convect.counter in common block
1111    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1112      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1113    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1114    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1115    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1116    o restore adjointability
1117    
1118    checkpoint53f_post
1119    o modifications that affect AIM experiment results (update output.txt):
1120      - no advection of S at top interface Nr (pkg/generic_advdiff)
1121      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1122    o AIM pkg:
1123      - include stability function into surf.Flux derivative relative to Tsurf
1124      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1125    
1126    checkpoint53e_post
1127    o merged cylindrical coord configuration
1128    o added rotating_tank experiment
1129    checkpoint53e_pre
1130    
1131    checkpoint53d_post
1132    o faulks upgraded: re-generate output.txt that have changed:
1133       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1134    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1135    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1136    o added Sadourny discretization of Coriolis
1137      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1138      - re-enabled use of omega3 (useAbsVorticity)
1139    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1140      vector-invariant equations
1141      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1142    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1143      hopefully without new bugs
1144      - still to do: biharmonic friction for non-hydrostatic w
1145    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1146    o regenerated output for global_ocean_ebm (using -ieee)
1147    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1148      of mom_common/
1149      - simple re-arrangement of instructions within computing loop
1150    checkpoint53d_pre
1151    
1152    checkpoint53c_post
1153    o new version of coupler for AIM+thSIce and Ocean models
1154     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1155     - land: change Evaporation of snow
1156     - aim with thSIce: fix bug in snow-precip.
1157    o changes to calc_gw.F
1158     - bug fix for w^2 term near the bottom boundary
1159     - (hopefully) improve the lateral slip boundary condtions for use with
1160        partial/looped cells
1161      - because the bug fix changes two verification experiments anyway (exp5
1162        and plume on slope), change the lateral boundary condition from half slip
1163        to the value of no_slip_sides
1164    o ebm package wasnt quite up to the parallel task. Fixed that.
1165    o Adjoint of EBM package + verification
1166      * TLM OK
1167      * ADM not sufficient accuracy yet (needs further testing)
1168    
1169    checkpoint53b_post
1170    o Commiting new energy balance model to repository
1171      * package is pkg/ebm
1172      * verif. is verification/global_ocean_ebm
1173      * references are in ebm_driver.F
1174    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1175    C        Global thermohaline circulation. Part I:
1176    C        Sensitivity to atmospheric moisture transport.
1177    C        J. Climate 12(1), 71-82
1178    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1179    C        Global thermohaline circulation. Part II:
1180    C        Sensitivity with interactive transport.
1181    C        J. Climate 12(1), 83-91
1182    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1183    C        Destabilization of the thermohaline circulation
1184    C        by atmospheric eddy transports.
1185    C        J. Climate 7(12), 1870-1882
1186    o Will need long integration testing.
1187    checkpoint53b_pre
1188    
1189    o created pkg/mom_common in preparation for variable viscosity code
1190    o renamed and split ini_mnc_io
1191    o pkg/land: only liquid water can diffuse or run-off
1192    o AIM using land: soil wetness availability account for snow
1193    o added printMapIncludesZeros to EEPARMS namelist
1194    
1195    checkpoint53a_post
1196    o restore TAMC compatiility for exf_constants.h
1197      (no usage of _d in .h)
1198    o Additional storing in KPP in an attempt to fix
1199      TAMC problem with adjoint of KPP code.
1200      (no success...)
1201      Identical code works fine with TAF.
1202    o Fixed verification/natl_box_adjoint experiments.
1203      Initial conditions for Experiments 4 and 5 are now
1204      set to "SEAICE_initialHEFF=0", which is more reasonable,
1205      and hence gives results closer to that of Experiment 2.
1206      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1207    
1208    checkpoint53
1209    o stable checkpoint with up to date adjoint
1210      TLM tests only run for 1st grdchk at the moment. Its unclear if
1211      this is a code problem or a problem with resetting code for g_
1212      variables that is being autogenerated wrong.
1213      Otherwise:
1214       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1215       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1216         are both still in chaos following their security messes.
1217    
1218    checkpoint52n_post
1219    o various build (mostly genmake2) changes including:
1220      - ability to build/run more easily within Cygwin and MacOS X
1221      - more complicated Makefiles with a stronger dependence on Gnu Make
1222    o pkg/seaice modifications
1223      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1224        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1225        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1226      - changed proxy for geostrophic velocity and updated
1227        verification/lab_sea/results/* accordingly
1228      - removed ADI dynamic solver from pkg/seaice
1229      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1230        they caused a segmentation fault under certain circumstances
1231      - removed unused field WATR
1232    o bug fix in exf-package:
1233      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1234         now reflect that.
1235    o small fixes in the cal-package:
1236      - set reference date to first of January for the 'model'-calendar
1237      - failing of cal_CheckDate in cal_FullDate now actually results in a
1238        warning
1239    o small modifications in exf-package to increase flexibility:
1240      - change climtempfreeze from a constant to a runtime parameter that
1241        is specified in data.exf_clim (default = -1.9)
1242      - introduce runtime parameter windstressmax (default = 2.0) that is
1243        specified in data.exf
1244    o fix in pkg/thsice:
1245      - update Evap (Tsf changes) to be consistent with Latent heat flux
1246      - maintain snow precipitation unchanged (even if Tsf >=0).
1247     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1248    
1249    checkpoint52m_post
1250    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1251      this does not change any of the results, because myIter=0 in swfrac always
1252      lead to jwtype=2 (the default anyway), but the call makes little sense
1253      as a default
1254    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1255    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1256      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1257    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1258    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1259    o extending useSingleCpuIO option to work with new exch2 I/O format
1260      - old-style, missing-tile I/O is still accessible by defining CPP
1261        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1262    o monitor package can write to NetCDF files and/or STDOUT
1263    o fix re-definition bug in MNC_GRID_INIT_ALL()
1264    o doc/api_reference added
1265      - a framework for building an API Reference Manual using all
1266        the "protex" comments embedded in the code
1267      - see pkg/generic_advdiff, pkg/mnc for examples
1268    o MNC:
1269      - make myThid the last argument for all subroutines
1270      - new default for the grid files: NO halos
1271      - add useMNC and other run-time flags
1272      - separate per-file-group handling of the unlimited dimension
1273      - early initialization of MNC w/ flags read at the eeboot stage
1274        and lookup tables set in initialize_fixed
1275      - write all MNC output to a freshly-created directory
1276    o thermodynamics sea-ice (thsice) is now tested with testreport.
1277    o test exp. advect_cs: use the standard cs32 grid ; update output.
1278    o Added functionality to grdchk:
1279      pick global i,j,k position (or nearest wet) where to perform check.
1280    
1281    checkpoint52l_post
1282    o new land formulation:
1283      a) use ground enthalpy as prognostic variable to ensure exact
1284         energy conservation.
1285      b) account for water temperature and for latent heat of freezing
1286         in all processes (rain, run-off, ground storage)
1287      c) compute surface and ground temperature implicitly.
1288    o aim_v23 modification for new land model:
1289      a) Treat separately land / ocean / sea-ice surface fluxes
1290         to allow implicit computation of land & sea-ice surface temp.
1291      b) add snow precipitation.
1292    checkpoint52l_pre
1293    
1294    o fix problem (when 1 tile is empty) in min/max monitor.
1295    o fix bug in timeAve (u,vZetatave in common block)
1296    o no restoring terms under ice for pkg/seaice
1297    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1298    o bug fix for pkg/seaice pickups
1299    o change MNC call locations and add coordinate attributes
1300    o mask vorticity at the corner ; affects global_ocean.cs output
1301    o fix ini_curvilinear_grid ; test CS experiments with mpi
1302    o aim.5l_cs: modify sea-ice fraction input file ; update output
1303    o exf: Adding simple range check routine for exf fields after read
1304    
1305    checkpoint52k_post
1306    o removed top-level directory "diags"
1307      - we migrated these functions to pkg/timeave a long time ago
1308    o fixed bug introduced in pkg/monitor
1309    o accuracy ctrlprec = 32 insuffient for gradient checks using
1310      averaged fields (I/O via cost_averages)
1311      -> use ctrl.h in active_file*.F to control I/O precision.
1312    o paramter list of CALL ADTHE_MAIN_LOOP
1313    o added initial do_the_model_io to ecco
1314    o set all ...Freq to zero after cost_final
1315      taveFreq, dumpFreq, pChkptFreq
1316    o MAIN and ECCO differentiability restored
1317    
1318    checkpoint52j_post
1319    o fix nchklev in tamc.h for global_ocean...
1320    o Bringing flow and store directives up-to-date
1321    o Really weird thing!
1322      call do_the_model_io from the_main_loop with parameters
1323      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1324      TAF places a faulty re-call of initialise_varia
1325      after cost_final call which should not be there!
1326    checkpoint52j_pre
1327    
1328    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1329      error messages
1330    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1331    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1332      debug output
1333    o modfied mdsio_writefield.F to handle non-global files under exch2
1334    o update AIM Cubed-Sphere exp (aim.5l_cs):
1335      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1336    o update AIM Equatorial Channel exp:
1337      use standard aim_v23 pkg and change the SST fields to be more realistic.
1338    o globalFile now works with exch2
1339    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1340      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1341    o limit timeave output for hi-res integrations
1342    
1343    checkpoint52i_post
1344    o removed CPP_EEOPTIONS.h from verification/*/code
1345    o updated the tiling for global_ocean_pressure
1346    checkpoint52i_pre
1347    
1348    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1349      the old pkg/aim).
1350    
1351    checkpoint52h_pre
1352    o shortened offending lines in exch2_send_rx?.template
1353    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1354    o genmake2: add build & execute test for NetCDF code
1355    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1356      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1357    o added useSingleCPUIO flag to monitor.F and mon_out.F
1358    o added temporary hack for sea-ice dynamics on the cube:
1359      metric terms are ignored and it is assumed that
1360      there is no sea-ice on cube faces 1, 2, 4, and 5.
1361    
1362    checkpoint52f_post
1363    o added exch2 cube routines to pkg/exch2
1364    o modified hs94.cs-32x32x5 to use it
1365    o added new grid files to hs94.cs-32x32x5
1366    checkpoint52f_pre
1367    
1368    checkpoint52e_post
1369    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1370      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1371    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1372      to work with implicit vertical advection and AB ;
1373    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1374    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1375     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1376    checkpoint52e_pre
1377    
1378    o fix bug in impldiff when Nr=1 or Nr=2.
1379    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1380    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1381    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1382      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1383    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1384    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1385    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1386    
1387    checkpoint52d_post
1388    o re-tiled many expts to allow comparison in multi-processor mode
1389      - updated output accordingly
1390      - changed hs94.128x64x5 to use intial T from file rather than use the
1391        random number generator
1392    o add infrastructure in model routines for fizhi and gridalt packages
1393    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1394    o changes to permit hi-res, cubed-sphere, configuration
1395      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1396      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1397      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1398        of surface winds for the cube
1399      (A verification experiment, based on global_ocean.cs32x15, but with
1400       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1401       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1402       complete with example surface forcing files and matlab scripts to look
1403       at the output and compare it with that of global_ocean.cs32x15.)
1404    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1405       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1406       to conform to the common rule.
1407    o check-in the first version of the coupler + interfaces for multi-components
1408       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1409       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1410       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1411       - ocean and atmos. share the same horizontal grid (no interpolation).
1412       - exchanges between component and coupler is done in forward_step
1413    o new verification experiment, cpl_aim+ocn:
1414       coupled ocean - AIM atmosphere on cs32 grid.
1415    
1416    checkpoint52d_pre
1417    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1418    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1419    
1420    checkpoint52c_post
1421    o Fixing OPTIONS files for use of exf:
1422      - ALLOW_ECCO not needed
1423      - ECCO_CPPOPTIONS.h should not be included from
1424        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1425        as has been the case in the past
1426      - All cal/exf related options are currently set in
1427        single header file. Should remain so until we
1428        agree on a consistent new policy.
1429    o Removed all CPP options for cal package.
1430      cal has no more CPP options.
1431    o modified STOREs in GAD_ADVECTION
1432    o corrected key comp. for passkey
1433    
1434    checkpoint52b_post
1435    o new version: "thsice" of thermodynamic sea-ice pkg:
1436     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1437     - modify fluxes but do not change theta directly;
1438     - light cleaning of bulk_force pkg (still needed with thsice).
1439     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1440       + output_thsice.txt to test thsice & bulk_force pkgs.
1441    o put back grid & coriolis monitor output.
1442    checkpoint52b_pre
1443    
1444    o call "do_the_model_io" at the beginning (=> dump initial state)
1445    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1446    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1447      (need info on NUMBER_OF_PTRACERS)
1448    o missing PTRACERS headers in some routines
1449    o default tamc.h in pkg/autodiff supposed to crash
1450      to ensure proper customization
1451    
1452    checkpoint52a_post
1453    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1454      - moved surfaceTendencyTice from pkg/seaice to main code
1455      - subroutine FREEZE_SURFACE now limits only surface temperature
1456        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1457        => new output.txt for global_ocean.cs32x15 & global_with_exf
1458      - keep the old version of FREEZE for backward compatibility;
1459        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1460      - corresponding modifs for TAF directives
1461    o added surface flux output variables to TIMEAVE_STATVARS
1462    o time-averaged output for pkg/ptracers
1463    o fix problem with ECCO-related divided adjoint
1464      snapshot file was missing some ad-variables,
1465      but no warning issued by TAF
1466    
1467    checkpoint52a_pre
1468    o some bug fixes for #undef REAL4_IS_SLOW
1469    
1470    checkpoint52 = ecco_c52_e35
1471    o after testing adjoints of checkpoint51u_post
1472    
1473    checkpoint51u_post
1474    o this is the post-merge tag of the ecco-branch
1475      (needs another clean checkout and re-testing)
1476    o various natl_box_adjoint configs and results
1477      but no input fields

1486    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1487    
1488    checkpoint51t_post
1489    o this is the pre-merge tag of the ecco-branch
1490    
1491    checkpoint51s_post
1492    o cleanup: removed various obsolete #define-s
1493    o pkg/grdchk
1494      - renamed 'ph-grd 3' to 'grad-res'
1495      - merged from ecco-branch
1496        (remaining bug fixes for obcs gradient checks)
1497      - additional high-precision output for testreport
1498        (grep for 'precision_grdchk_result')
1499    
1500    checkpoint51r_post
1501    o cleaned up or removed CPP_OPTIONS.h files
1502    o updated results for some of the tests to reflect the new
1503      optfiles (-ieee: -O0 instead of -O3)
1504    
1505    checkpoint51q_post
1506    o cd_code:
1507      - moved cd_scheme.F -> cd_code_scheme.F
1508      - separate read_checkpoint from cd_code_ini_vars.F

1519    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1520    
1521    checkpoint51p_post
1522    o create initial cd_code package
1523      - WARNING: the initialization of fields within packages
1524        is broken because INI_FIELDS (where READ_CHECKPOINT is
1525        called) is called *before* PACKAGES_INIT_VARIABLES.
1526        This seems to be backwards since
1527        1) its important to initially zero the entire field including
1528           the "halo" region
1529        2) zeroing needs to be done *before* reading pickup info
1530           and the pickup call might or might not happen in any
1531           particular run
1532      - this needs an overhaul for R2
1533    o cleanup verification/*/code/GMREDI_OPTIONS.h

1567      - moved surfaceTendencyTice from pkg/seaice to main code
1568      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1569      - subroutine FREEZE now limits only surface temperature
1570        (this means new output.txt for global_ocean.90x40x15,
1571         global_ocean.cs32x15, and global_with_exf)
1572    o added surface flux output variables to TIMEAVE_STATVARS

1622      Moving pkg-specific differentiation list to corresponding pkg
1623      Moving pkg-specific checkpoint-lev storing to corresponding pkg
1624      ---> conventions are

1627           - pkg_ad_check_lev?_dir.h
1628    
1629    checkpoint51i_post

1661    o Added on-the-fly spatial interpolation capability
1662        "USE_EXF_INTERPOLATION" to pkg/exf.
1663      - This is a temporary Cartesian-grid hack until
1664        the super-duper ESMF coupler becomes available.
1665      - See verification/global_with_exf/README for usage example.
1666      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1667        flags and modified pkg/seaice accordingly.
1668    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1669        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1670        non-local transport term.
1671    
1672    checkpoint51e_post
1673    o pkg/mom_vecinv:
1674      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1693      - affected packages: autodiff, ctrl, grdchk, mdsio
1694    
1695    checkpoint51c_post
1696    o introducing integer flag debugLevel
1697      - debLevZero: suppress all output
1698      - debLevA: standard
1699      - debLevB: equivalent to current debugMode=.TRUE.
1700    o introducing pathname variable mdsioLocalDir for mdsio
1701      that can be specified at runtime
1702      (relevant for cluster I/O to local disk)
1703    `
1704    >>>checkpoint51b_post
1705    adjoint of ptracers
1706    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1707    o extended state in checkpoint_lev?, etc.
1708    o alternative ctrl/cost with tr1 or ptracer
1709    o new comlev1_bibj_ptracers
1710    o new ptracers.flow
1711    o made ptracers_forcing same as external_forcing_s
1712    o added verification for adjoint with ptracers
1713      - adm. grdchk fail so far
1714      - tlm. grdchk OK
1715      - checked tapelev/comlev recomputations: OK
1716    <<<checkpoint51b_pre
1717    
1718    checkpoint51a_post
1719    o added code for biogeochemistry package
1720      - new pkgs: dic, gchem
1721      - new subroutine in ptracers
1722    o modify code for biogeo packages
1723      - in model/src and pkg/ptracers
1724    
1725    checkpoint51
1726    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1727      - autodiff, ctrl, exf, grdchk, seaice
1728      kept separate packages
1729      - cost, ecco, obcs
1730    o updating verification/internal_wave, verification/lab_sea
1731      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1732    
1733    checkpoint50i_post
1734    o Preparing next differentiable checkpoint and sync
1735      of MAIN vs. ecco-branch
1736      - 1st step: this one is differentiable
1737      - 2nd step: next(! not this) checkpoint will have updated packages
1738                  from ecco-branch)
1739    
1740    checkpoint50h_post
1741    o new package "land": provide surface BC for AIM.
1742    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1743    o AIM: use true log-P extrapolation for near surface temp (= as in
1744        F.Molteni paper) ; update aim.5l_cs output.
1745    o New variable in PARM03 for more flexible pickups
1746    o somewhat cleaned package initialisation sequence for
1747      ctrl/ cost/ ecco/ in packages_... routines
1748    
1749    checkpoint50g_post
1750    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1751      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1752      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1753        made the default because of faster convergence than ADI
1754    
1755    checkpoint50f_post
1756    o exf totally restructured
1757      - replaced all exf_set_ routines by one generic exf_set_gen.F
1758        and made sure it's still differentiable
1759      - split exf_getffields.F into new exf_bulkformulae.F
1760      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1761      - updated adjoint/makefile and relevant verif. accordingly
1762    
1763    checkpoint50f_pre

1771     o removed lots of single quotes from comments
1772    
1773    checkpoint50e_post
1774    o make KPP work with PTRACERS
1775     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1776       nearly a copy of kpp_transport_s
1777     - there is no analogue to SurfaceTendencyS, so I have to use
1778       gPtr(of the surface layer) instead
1779    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1780    checkpoint50e_pre
1781    
1782    checkpoint50d_post
1783    o change kpp output from multiple-record state files to single-record state
1784      files analogous to write_state.F
1785    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1786      analogous to the cg2d-related output.
1787    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1788      so that writing to internal file fn (with length 512) fails.
1789    checkpoint50d_pre
1790    
1791    checkpoint50c_post
1792    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1793    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1794    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1795    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1796    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1797    
1798    checkpoint50c_pre
1799    Merging from release1_p13:
1800    o bug fix for pkg/seaice dynamic solver
1801    o Added SEAICE_initialHEFF to pkg/seaice
1802    
1803    checkpoint50b_post
1804    o store u*,v* in gU,V instead of in guNm1,gvNm1
1805    o in order to put the momForcing out of the Adams-Bashforth:
1806      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1807      to timestep.F
1808    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1809    o re-generate output for highly sensitive test-exp:
1810       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1811    
1812    checkpoint50b_pre
1813    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1814    o corrected CPP option mismatch in exf_Bulk... functions for case
1815      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1816    
1817    checkpoint50a_post
1818    o Bug fix for merging between c50 and KPP.
1819      ikey was passed from thermodynamics to kpp_calc via
1820      common block rather than being recomputed in kpp_calc,
1821      in contradiction with new key itdkey.
1822      New key ikppkey created, and tamc.h headers updated.
1823    
1824    checkpoint50
1825    - 2nd step of merge with ecco-branch:
1826      merge changes in ecco-branch back into main trunk
1827    - bug fix in find_alpha
1828    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1829    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1830    - merged some sliced AD support routines
1831    
1832    checkpoint49
1833    merged from ecco-branch:
1834    o exf:
1835      - Enable initialisation of forcing fields to constant
1836        (runtime) values.
1837      - in exf_getffields.F
1838        Reduce i-/j-loop to interior domain, discarding overlaps.
1839        That also fixes wrong TAF-key computations for key_1, key_2
1840        with bulf formulae.
1841      - exf_init.F modify #ifdef for exf_init_evap
1842      - exf_getffieldrec.F, ctrl_getrec.F
1843        The following INT-usages are not safe:
1844          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1845          fldcount = int(fldsecs/fldperiod) + 1
1846        and were modified.
1847    o autodiff: checkpoint_lev...
1848      - updated storing for bulk formulae (some arrays were missing)
1849      - added state for seaice package
1850      - synchronized with main branch
1851    o DIVA:
1852      Modif.s in
1853      - the_main_loop.F
1854      - the_model_main.F
1855      and added cost_final_restore.F cost_final_store.F
1856      o With these changes, it is possible to fully separate
1857        the first forward run to compute the cost function (mdthe_main_loop)
1858        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1859        into separate model executions.
1860        This enables better tuning of DIVA to given queue sizes.
1861      o Loss of cost function value in consecutive DIVA runs is
1862        fixed by storing to 'costfinal' file.
1863      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1864        beginning/end of adjoint integration is accounted for.
1865      The current changes apply to TAF-1.4.26.
1866      TAF has one remaining bug, requiring one manual change
1867      (see MITgcm manual).
1868    o cal: synchronized between MAIN and ecco-branch
1869    
1870    checkpoint48i_post
1871    o Changes to restore differentiability of code w.r.t. previous tag
1872      (mostly adding new routines to make list and replacing
1873      pressure by totPhiHyd).
1874    o Updated and merged grdchk package
1875      - has both ADM and TLM checks
1876      - works for single- and multi-proc.
1877      - output cleaned
1878      - worked successfully for parallel DIVA
1879    o genmake:
1880      - Adding -platform=SP4
1881      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1882    o Modif. for DIVA:
1883      ctrl_unpack should not be called in intermediate DIVA interval.
1884      (similar thing would apply for active files such as
1885      tbar, sbar, psbar, which should not be reinitialised;
1886      only relevant for ecco-branch)
1887    
1888    checkpoint48h_post
1889    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1890    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1891    o Added SEAICE_initialHEFF to pkg/seaice
1892    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1893    
1894    checkpoint48g_post
1895    --- EOS:
1896    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1897      store total Potential in totPhyHyd for diagnostics & EOS.
1898    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1899    --- Pressure/geopotential gradient:
1900    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1901    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1902      ( changes results of global_ocean_pressure )
1903    o NLFS + z-coord.: add eta*Rho' contribution.
1904    o accurate phiHyd when using interface-W at the middle between 2 centers
1905     ( changes results of ideal_2D_oce )
1906    o includes r* 2nd term in potential gradient.
1907    
1908    checkpoint48f_post
1909    Merging from release1_p12:
1910    o Modifications for using pkg/exf with pkg/seaice
1911      - improved description of the various forcing configurations
1912      - added basic radiation bulk formulae to pkg/exf
1913      - units/sign fix for evap computation in exf_getffields.F
1914      - updated verification/global_with_exf/results/output.txt
1915    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1916      (SBO) core products, including oceanic mass, center-of-mass,
1917      angular, and bottom pressure (see pkg/sbo/README.sbo).
1918    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1919      to avoid negative values in shallow regions.
1920      - updated verification/natl_box/results/output.txt
1921      - updated verification/lab_sea/results/output.txt
1922    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1923    o Added useSingleCpuIO option (see PARAMS.h).
1924    o Updated useSingleCpuIO option in mdsio_writefield.F to
1925      work with multi-field files, e.g., for single-file pickup.
1926    o pkg/seaice:
1927      - bug fix in growth.F: QNET for no shortwave case
1928      - added HeffFile for specifying initial sea-ice thickness
1929      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1930    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1931      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1932    o pkg/seaice:
1933      - adjoint-friendly modifications
1934      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1935    
1936    checkpoint48e_post
1937    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1938    o dynamics: change definition of computational domain & adapt mom_fluxform
1939      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1940    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1941        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1942        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1943        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1944        inverted_barometer solid-body.cs-32x32x1
1945      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1946    
1947    checkpoint48d_post
1948    o in preparation for r*:
1949     a) use pre-computed gradient of hydrostatic potential:
1950        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1951     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1952        => affects results of glob_oce_pressure (different truncation error)  
1953      update output.txt of ideal_2D_oce & global_ocean_pressure
1954    
1955    checkpoint48d_pre
1956    o in preparation for r*:
1957      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1958      pass the 2 comp. of the grad. as arguments to momentum S/R.
1959      but for the moment, only used if it does not change the results.
1960    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1961    
1962    checkpoint48c_post
1963    Modifications in treatment of initial flux forcing controls
1964    to avoid extra storing of flux fields.
1965    
1966    checkpoint48c_pre
1967    o Added tidal_basin_2d experiment (currently 1D!)
1968    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1969    
1970    checkpoint48b_post
1971    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1972     (modification to pressure gradient not yet implemented)
1973    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1974      (for U & V) that are used for vertical advection of momentum.
1975    
1976    checkpoint48a_post
1977    o In preparation for r*, use temp. array to compute vertical transport
1978       in flux-form momentum pkg. => change results of few test-exp.
1979      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1980                        lab_sea, natl_box & plume_on_slope
1981    
1982    checkpoint48
1983    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1984    
1985    checkpoint47j_post
1986    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1987    o moved adexch from forward_step to addummy_in_stepping
1988    o added exch in ctrl_map_...
1989    o aveFreq.=0. at end of cost_final to avoid overwrite in
1990      reverse checkpointing loop
1991    o Yet more changes in gmredi:
1992      * adgmredi_calc_tensor
1993        avoiding all recomputation of gmredi_slope_limit
1994      * adgmredi_x/y/rtransport
1995        added flag for excessive storing to avoid recomp. of
1996        u/v/rtans, dTdx/y/z
1997        -> this is not really necessary and very memory-consuming
1998      * adgmredi_slope_psi:
1999        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
2000      * gmredi_slope_limit
2001        re-activated full calculation of taperfct for case 'ac02'
2002    o updating verification/ adjoints of carbon, global_ocean.90x40x15
2003    
2004    checkpoint47i_post
2005    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
2006    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
2007      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
2008    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
2009    o gmredi: fix few bugs.
2010    
2011    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
2012    This will be a good checkpoint to plug into the ecco-branch.
2013    o few modif.'s to get latest version adjointed
2014      (mainly kick out code in ini_linear_phisurf)
2015    o modif's to run adjoint with exactConserv
2016    o case GM_BOLUS_ADVEC should be cleaned
2017      S/R gmredi_slope_psi should be cleaned
2018    o verification/carbon now has exactConserv=.TRUE.
2019    
2020    checkpoint47g_post
2021    o time-average AIM output: becomes independent from statvars time-average
2022      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
2023    o After TAF bug fix:
2024      Tested adjoint of gmredi package.
2025      Tests were done with checkpoint47 rather than with latest
2026      checkpoint47f_post since the latter is broken for the adjoint
2027      verification/carbon/ contains both ADM and TLM gradient checks.
2028    Here they are, before they get changed/lost/stolen.
2029    Mostly modif.'s to fix numerical sensitivities.
2030    Gradient checks OK for
2031    - GM_taper_scheme:
2032      * clipping
2033      * ac02
2034      * linear
2035      * glw91
2036      * dm95
2037      * ldd97
2038    - GMREDI_OPTIONS:
2039      * GM_VISBECK_VARIABLE_K
2040      * GM_NON_UNITY_DIAGONAL
2041      * GM_EXTRA_DIAGONAL
2042      * GM_BOLUS_ADVEC
2043    in conjunction with data.gmredi parameters to be checked in
2044    in a few minutes under verification/carbon/code/
2045    
2046    checkpoint47f_post
2047    Merging from release1_p10:
2048    o modifications for using pkg/exf with pkg/seaice
2049      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
2050        and SEAICE_EXTERNAL_FLUXES
2051      - pkg/exf CPP options EXF_READ_EVAP and
2052        EXF_NO_BULK_COMPUTATIONS
2053      - usage examples are Experiments 8 and 9 in
2054        verification/lab_sea/README
2055      - verification/lab_sea default experiment now uses
2056        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
2057    
2058    checkpoint47e_post
2059    o created a tag prior to creating a branch
2060    
2061    checkpoint47d_post
2062    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
2063      at the bottom boundary had an erroneous half slip boundary condition
2064    o added bottom drag and no slip boundary condition capabilities to
2065      oceanic pressure coordinates code
2066    o added new verification experiment global_ocean_pressure, this experiment is
2067      also described in the tutorial section of the manual
2068    checkpoint47d_pre
2069    
2070    checkpoint47c_post
2071    o Added a verification experiment for a global cubed-sphere ocean run
2072      -  verification/global_ocean.cubed32x32x30
2073      -  uses pkg/therm_seaice and pkg/bulk_forcing
2074    
2075    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
2076    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
2077      when using P-coordinate; only implemented for atmospheric config.
2078    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
2079      NOTES: requires option NONLIN_FRSURF to be "#define".
2080    o update advect_xz/results/output.txt (left from checkpoint44g_post)
2081    
2082    checkpoint47b_post
2083    Merging from release1_p9:
2084    o pkg/seaice
2085      - removed GOTO's and added taf directives
2086      - double precision constants to reduce the g77 (Linux)
2087        to F77 (SGI) differences reported in release1_p8
2088    o tools/genmake
2089      - added SGI options
2090    o verification/testscript
2091      - updated to that of checkpoint47a_post
2092    o verification/global_ocean.90x40x15/input/eedata
2093      - modified for SGI f77 compatibility
2094    o verification/lab_sea
2095      - added description of sea-ice model
2096      - added missing matlab routines
2097      - added test of thermodynamics parallelization
2098    
2099    checkpoint47a_post
2100    o new pkg: aim_v23
2101     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
2102       for now, keep the same surface forcing as before.
2103     - Part-Cell implemented into AIM; check that Heat & Water are conserved
2104     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
2105     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
2106    o add diagnostic of surface correction term in monitor output
2107    
2108    o bulk_force and therm_seaice
2109    - Two packages:  bulk_force (Bulk forcing)
2110      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
2111    - Earlier integration from Stephaine Dutkiewicz
2112      and Patrick Heimbach.
2113    - Two ifdef statements for compile time,
2114       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
2115    
2116    checkpoint47
2117    differentiable version of checkpoint46n_post
2118    o bug fix in quasihydrostaticterms
2119    o * "clean" adjoint code (in terms of extensive recomputations)
2120        can now be obtained for all GMREDI options (i.e. for
2121        - GM_VISBECK_VARIABLE_K
2122        - GM_NON_UNITY_DIAGONAL
2123        - GM_EXTRA_DIAGONAL
2124        - GM_BOLUS_ADVEC )
2125      * However, wrong gradient check problem remains unsolved.
2126      * New CPP options have been introduced for different
2127        tapering schemes
2128    o external_fields_load now part of differentiation list
2129    o pressure needs multiple storing;
2130      would be nice to have store_pressure at beginning or
2131      end of forward_step, e.g. by having phiHyd global (5-dim.)
2132      (NB: pressure is needed for certain cases in find_rho,
2133      which is also invoked through convective_adjustment).
2134    o recomputations in find_rho for cases
2135     'JMD95'/'UNESCO' or 'MDJWF' are OK.
2136    o #define ATMOSPHERIC_LOADING should be differentiable
2137    o ini_forcing shifted to begining of initialise_varia
2138    o Incorporating QNVS line search routines into MITgcm
2139      (this is separate code, and therefore not under pkg)
2140      lsopt/, optim/
2141    o Updated verification/carbon/
2142      - #define GM_VISBECK_VARIABLE_K
2143      - GM_taper_scheme    = 'ldd97'    
2144    
2145    checkpoint46n_post
2146    Merging from release1_p8:
2147    o verification/natl_box:
2148      updating new external_fields_load routine
2149    o New package: pkg/seaice
2150      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
2151      The sea-ice code is based on Hibler (1979-1980).
2152      Two sea-ice dynamic solvers, ADI and LSR, are included.
2153      In addition to computing prognostic sea-ice variables and diagnosing
2154      the forcing/external data fields that drive the ocean model,
2155      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2156      The implied surface heat flux is then stored in variable
2157      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2158      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2159      non-local transport term.  Because this call precedes model
2160      thermodynamics, temperature under sea-ice may not be "exactly" at
2161      the freezing point by the time theta is dumped or time-averaged.
2162      N.B.: fairly large differences in accuracy occur across
2163            different platforms/compilers; comparison between
2164            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2165            generated output gives:
2166       T           S           U           V
2167      C D M    c        m  s        m  s        m  s        m  s
2168      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
2169      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

2171    
2172      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2173    o GAD:
2174      - generated new common blocks to account for call of
2175        same gad routines with differing traceridentities
2176        (needed to modify tracerIdentity indices in GAD.h)
2177      - generated separate common blocks for case useCubedSphereExchange
2178        (Department of Futurology)
2179      - parameter lists to gmredi_?transport: added tracerIdentity
2180      - added new key indices to tamc.h
2181    o external_fields_load:
2182      - added this routine to TAF list
2183      - needed to make some common blocks global and additional storing
2184        along the same lines as exf package (checkpoint_lev?_directives.h)
2185    o exf:
2186      updated external forcing package
2187      - bug fixes carried over from ecco-branch
2188        (missing OBCS_OPTIONS.h in two routines)
2189      - enable easy to use "no forcing".
2190      - added exf I/O for atmospheric loading
2191      - added exf I/O for runoff data
2192      - transfered scaling between exf <-> MITgcm to exf namelist
2193    o Adding new verification experiment global_with_exf.
2194      This verification experiment is almost identical to the
2195      global_ocean.90x40x15 experiment, except that it uses
2196      the exf (and cal) package instead of the
2197      external_fields_load routine (cf README file).
2198    
2199    checkpoint46m_post
2200    o modified testscript to return -- when there are no lines of "%MON" output
2201    o added new flag "quasiHydrostatic" for QH mode
2202      and new routine quasihydrostaticterms()
2203    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2204      New routine: mom_u_coriolis_nh()
2205    o fixed sign of non-hydrostatic metric terms in u and v equations.
2206      Depend on correct sign of gravitySign.
2207    o added work.pc* to .cvsignore in aim directories using ifc
2208    o introduced flag for controllin non-hydrostatic metric terms
2209    o removed gravitySign from PARM04
2210    o switched to g77/ifc from pgf77 in aim experiments
2211    
2212    checkpoint46l_post
2213    o made convective adjustment work with pressure coordinates:
2214     - changed the direction of k-loop in convective_adjustment.F for the
2215       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2216     - adjusted the reference pressure k-index in convective_adjustment.F
2217     - adjusted the convection condition in convect.F (in analogy to
2218       calc_ivdc.F)
2219     - convective_adjustment no longer computes anything on the halos
2220     - removed the warnings about negative salinity from find_rho.F and
2221       find_alpha.F; instead the new routine look_for_neg_salinity, called
2222       at the beginning of find_rho, find_alpha, and find_beta, does a
2223       check of the entire slice, if CPP-option
2224       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2225    checkpoint46l_pre
2226    
2227    checkpoint46k_post
2228    o fixed the verification/global_ocean.90x40x15 experiment:
2229     - new bathymetry (the world according to A., JMC, and M.)
2230     - new initial fields and forcing fields (*.bin files)
2231     - new POLY3.COEFFS (for the next release one should switch to a full
2232       equation of state: JMD95P or MDJWF)
2233     - fixed several errors and redundancies in the data file
2234     - experiment uses looped cells
2235     - added matlab directory with diagnostic scripts for plotting of output
2236    
2237    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2238     - read AIM physics parameters from a file (data.aimphys)
2239     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2240    
2241    checkpoint46j_post
2242    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2243    o move wVel computation at the end of the time step, in S/R integr_continuity
2244    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2245    o update timeave pkg for wVel diagnostic.
2246    checkpoint46j_pre
2247    
2248    checkpoint46i_post
2249    o Clean up AIM package (and keep the results unchanged):
2250      include CPP_OPTION and use IMPLICT NONE in all routines ;
2251      declare all the variables _RL ; use _d 0 for all numerical constants.
2252      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2253    
2254    checkpoint46h_post
2255    o cleaned up the use of rhoNil and rhoConst.
2256      - rhoNil should only appear in the LINEAR equation of state, everywhere
2257        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2258        and the dynamical equations are all divided by rhoConst
2259    o introduced new parameter rhoConstFresh, a reference density of fresh
2260      water, to remove the fresh water flux's dependence on rhoNil. The default
2261      value is 999.8 kg/m^3
2262    o cleanup up external_forcing.F and external_forcing_surf.F
2263      - can now be used by both OCEANIC and OCEANICP
2264    checkpoint46h_pre
2265    
2266     Added code to convert surface volume flux (fresh water) into
2267     a mass flux when using P coordinates in the ocean (OCEANICP).
2268     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2269    
2270    checkpoint46g_post
2271    o Include a new diagnostic variable phiHydLow for the ocean model
2272      - in z-coordinates, it is the bottom pressure anomaly
2273      - in p-coordinates, it is the sea surface elevation
2274      - in both cases, these variable have global drift, reflecting the mass
2275        drift in z-coordinates and the volume drift in p-coordinates
2276      - included time averaging for phiHydLow, be aware of the drift!
2277    o depth-dependent computation of Bo_surf for pressure coordinates
2278      in the ocean (buoyancyRelation='OCEANICP')
2279      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2280        Theta, Salinity, and Pressure in the parameter list. This routine is
2281        presently contained in find_rho.F. This routine does not give the
2282        correct density for 'POLY3', which would be a z-dependent reference
2283        density.
2284    o cleaned up find_rho
2285      - removed obsolete 'eqn' from the parameter list.
2286    o added two new verification experiments: gop and goz
2287      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2288    checkpoint46g_pre
2289    
2290    checkpoint46f_post
2291    o Enable tangent linear (forward mode) gradient checks:
2292      - extended active file handling to g_... files
2293      - added TANGENT_SIMULATION to theSimulationMode
2294      - extended grdchk package accordingly
2295    o added tangent linear setup in verification/carbon/code_ftl
2296    o added adjoint setup in verification/front_relax/code_ad
2297    
2298    checkpoint46e_post
2299    o Added new equation of state -> MDJWF
2300      - EOS of McDougall et al., 2002, JAOT, submitted
2301      - caveat: the equation of state is only valid for a smaller (more
2302        realistic?) range of values than JMD95P/Z and UNESCO
2303      - added masks to the calculation of pressure in store_pressure
2304      - added more check values for density in check_eos (ini_eos.F), some of
2305        the old check values are out of the range of the MDJWF-eos, so don't
2306        expect perfect matches for those
2307    checkpoint46e_pre
2308    
2309    checkpoint46d_post
2310    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2311      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2312      case of pressure coordinates. eosType='JMD95Z' in
2313      combination with buoyancyRelation='OCEANICP' now causes an error.
2314    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2315      in find_alpha/beta.
2316    checkpoint46d_pre
2317    
2318    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2319      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2320    
2321    checkpoint46c_post
2322    o Changes necessary for ocean in p-coordinates
2323     -  Added new buoyancy relation = 'OCEANICP'
2324     -  Added new parameters = gravitySign (this used to be contained inside
2325        the factor dRdZ which I added when we first switched to R coordinates).
2326     X GM/Redi is not compatible (yet)
2327     X bottom drag and no-slip need to be debugged.
2328    checkpoint46c_pre
2329    
2330    checkpoint46b_post
2331    o Added new equation of state -> JMD95Z and JMD95P
2332      - EOS of Jackett and McDougall, 1995, JAOT
2333      - moved all EOS parameters into EOS.h
2334      - new routines ini_eos.F, store_pressure.F
2335    o Added UNESCO EOS, but not recommended because it requires
2336      in-situ temperature (see JMD95)
2337    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2338      unesco.f to be used with POLY3
2339    checkpoint46b_pre
2340    
2341    checkpoint46a_post
2342    o Added (atmospheric) pressure loading
2343      - new field in FFIELDS.h, etc...
2344      - new cpp flag ATMOSPHERIC_LOADING
2345    o Changed hFacC to _hFacC in calc_phi_hyd.F
2346    o Added SHORTWAVE_HEATING to some files for consistency
2347    checkpoint46a_pre
2348    
2349    checkpoint46
2350    further merges from release1_p5
2351    o new ctrl package
2352      - adopted from ECCO environment to enable optimization
2353      - added Eliassen Palm fluxes to controls

2355    o cost package
2356      - Compatible with new ctrl package
2357      - added Eliassen Palm cost hooks
2358      - modif's of existing cost functions
2359    o Adjoint-related bug fixes in kpp:
2360      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2361      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2362    o autodiff package
2363      - flow directives:
2364        + new for S/R do_the_model_io

2368        disable adcommon.h/g_common.h by default.
2369      - fixed problem for adjoint of global_max
2370    o modified verification/carbon/
2371    o New setup for adjoint of global_ocean

2376    checkpoint45d_post
2377    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2378    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2379      (affects plume_on_slope "cg2d" output)
2380    o add new parameter deltaTfreesurf for free-surface time stepping
2381    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2382  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
