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

1149    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1150    C        Global thermohaline circulation. Part II:
1151    C        Sensitivity with interactive transport.

1153    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1154    C        Destabilization of the thermohaline circulation
1155    C        by atmospheric eddy transports.
1156    C        J. Climate 7(12), 1870-1882
1157    o Will need long integration testing.
1158    checkpoint53b_pre
1159    
1160    o created pkg/mom_common in preparation for variable viscosity code
1161    o renamed and split ini_mnc_io
1162    o pkg/land: only liquid water can diffuse or run-off
1163    o AIM using land: soil wetness availability account for snow
1164    o added printMapIncludesZeros to EEPARMS namelist
1165    
1166    checkpoint53a_post
1167    o restore TAMC compatiility for exf_constants.h
1168      (no usage of _d in .h)
1169    o Additional storing in KPP in an attempt to fix
1170      TAMC problem with adjoint of KPP code.
1171      (no success...)
1172      Identical code works fine with TAF.
1173    o Fixed verification/natl_box_adjoint experiments.
1174      Initial conditions for Experiments 4 and 5 are now
1175      set to "SEAICE_initialHEFF=0", which is more reasonable,
1176      and hence gives results closer to that of Experiment 2.
1177      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1178    
1179    checkpoint53
1180    o stable checkpoint with up to date adjoint
1181      TLM tests only run for 1st grdchk at the moment. Its unclear if
1182      this is a code problem or a problem with resetting code for g_
1183      variables that is being autogenerated wrong.
1184      Otherwise:
1185       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1186       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1187         are both still in chaos following their security messes.
1188    
1189    checkpoint52n_post
1190    o various build (mostly genmake2) changes including:
1191      - ability to build/run more easily within Cygwin and MacOS X
1192      - more complicated Makefiles with a stronger dependence on Gnu Make
1193    o pkg/seaice modifications
1194      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1195        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1196        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1197      - changed proxy for geostrophic velocity and updated
1198        verification/lab_sea/results/* accordingly
1199      - removed ADI dynamic solver from pkg/seaice
1200      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1201        they caused a segmentation fault under certain circumstances
1202      - removed unused field WATR
1203    o bug fix in exf-package:
1204      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1205         now reflect that.
1206    o small fixes in the cal-package:
1207      - set reference date to first of January for the 'model'-calendar
1208      - failing of cal_CheckDate in cal_FullDate now actually results in a
1209        warning
1210    o small modifications in exf-package to increase flexibility:
1211      - change climtempfreeze from a constant to a runtime parameter that
1212        is specified in data.exf_clim (default = -1.9)
1213      - introduce runtime parameter windstressmax (default = 2.0) that is
1214        specified in data.exf
1215    o fix in pkg/thsice:
1216      - update Evap (Tsf changes) to be consistent with Latent heat flux
1217      - maintain snow precipitation unchanged (even if Tsf >=0).
1218     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1219    
1220    checkpoint52m_post
1221    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1222      this does not change any of the results, because myIter=0 in swfrac always
1223      lead to jwtype=2 (the default anyway), but the call makes little sense
1224      as a default
1225    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1226    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1227      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1228    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1229    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1230    o extending useSingleCpuIO option to work with new exch2 I/O format
1231      - old-style, missing-tile I/O is still accessible by defining CPP
1232        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1233    o monitor package can write to NetCDF files and/or STDOUT
1234    o fix re-definition bug in MNC_GRID_INIT_ALL()
1235    o doc/api_reference added
1236      - a framework for building an API Reference Manual using all
1237        the "protex" comments embedded in the code
1238      - see pkg/generic_advdiff, pkg/mnc for examples
1239    o MNC:
1240      - make myThid the last argument for all subroutines
1241      - new default for the grid files: NO halos
1242      - add useMNC and other run-time flags
1243      - separate per-file-group handling of the unlimited dimension
1244      - early initialization of MNC w/ flags read at the eeboot stage
1245        and lookup tables set in initialize_fixed
1246      - write all MNC output to a freshly-created directory
1247    o thermodynamics sea-ice (thsice) is now tested with testreport.
1248    o test exp. advect_cs: use the standard cs32 grid ; update output.
1249    o Added functionality to grdchk:
1250      pick global i,j,k position (or nearest wet) where to perform check.
1251    
1252    checkpoint52l_post
1253    o new land formulation:
1254      a) use ground enthalpy as prognostic variable to ensure exact
1255         energy conservation.
1256      b) account for water temperature and for latent heat of freezing
1257         in all processes (rain, run-off, ground storage)
1258      c) compute surface and ground temperature implicitly.
1259    o aim_v23 modification for new land model:
1260      a) Treat separately land / ocean / sea-ice surface fluxes
1261         to allow implicit computation of land & sea-ice surface temp.
1262      b) add snow precipitation.
1263    checkpoint52l_pre
1264    
1265    o fix problem (when 1 tile is empty) in min/max monitor.
1266    o fix bug in timeAve (u,vZetatave in common block)
1267    o no restoring terms under ice for pkg/seaice
1268    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1269    o bug fix for pkg/seaice pickups
1270    o change MNC call locations and add coordinate attributes
1271    o mask vorticity at the corner ; affects global_ocean.cs output
1272    o fix ini_curvilinear_grid ; test CS experiments with mpi
1273    o aim.5l_cs: modify sea-ice fraction input file ; update output
1274    o exf: Adding simple range check routine for exf fields after read
1275    
1276    checkpoint52k_post
1277    o removed top-level directory "diags"
1278      - we migrated these functions to pkg/timeave a long time ago
1279    o fixed bug introduced in pkg/monitor
1280    o accuracy ctrlprec = 32 insuffient for gradient checks using
1281      averaged fields (I/O via cost_averages)
1282      -> use ctrl.h in active_file*.F to control I/O precision.
1283    o paramter list of CALL ADTHE_MAIN_LOOP
1284    o added initial do_the_model_io to ecco
1285    o set all ...Freq to zero after cost_final
1286      taveFreq, dumpFreq, pChkptFreq
1287    o MAIN and ECCO differentiability restored
1288    
1289    checkpoint52j_post
1290    o fix nchklev in tamc.h for global_ocean...
1291    o Bringing flow and store directives up-to-date
1292    o Really weird thing!
1293      call do_the_model_io from the_main_loop with parameters
1294      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1295      TAF places a faulty re-call of initialise_varia
1296      after cost_final call which should not be there!
1297    checkpoint52j_pre
1298    
1299    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1300      error messages
1301    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1302    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1303      debug output
1304    o modfied mdsio_writefield.F to handle non-global files under exch2
1305    o update AIM Cubed-Sphere exp (aim.5l_cs):
1306      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1307    o update AIM Equatorial Channel exp:
1308      use standard aim_v23 pkg and change the SST fields to be more realistic.
1309    o globalFile now works with exch2
1310    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1311      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1312    o limit timeave output for hi-res integrations
1313    
1314    checkpoint52i_post
1315    o removed CPP_EEOPTIONS.h from verification/*/code
1316    o updated the tiling for global_ocean_pressure
1317    checkpoint52i_pre
1318    
1319    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1320      the old pkg/aim).
1321    
1322    checkpoint52h_pre
1323    o shortened offending lines in exch2_send_rx?.template
1324    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1325    o genmake2: add build & execute test for NetCDF code
1326    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1327      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1328    o added useSingleCPUIO flag to monitor.F and mon_out.F
1329    o added temporary hack for sea-ice dynamics on the cube:
1330      metric terms are ignored and it is assumed that
1331      there is no sea-ice on cube faces 1, 2, 4, and 5.
1332    
1333    checkpoint52f_post
1334    o added exch2 cube routines to pkg/exch2
1335    o modified hs94.cs-32x32x5 to use it
1336    o added new grid files to hs94.cs-32x32x5
1337    checkpoint52f_pre
1338    
1339    checkpoint52e_post
1340    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1341      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1342    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1343      to work with implicit vertical advection and AB ;
1344    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1345    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1346     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1347    checkpoint52e_pre
1348    
1349    o fix bug in impldiff when Nr=1 or Nr=2.
1350    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1351    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1352    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1353      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1354    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1355    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1356    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1357    
1358    checkpoint52d_post
1359    o re-tiled many expts to allow comparison in multi-processor mode
1360      - updated output accordingly
1361      - changed hs94.128x64x5 to use intial T from file rather than use the
1362        random number generator
1363    o add infrastructure in model routines for fizhi and gridalt packages
1364    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1365    o changes to permit hi-res, cubed-sphere, configuration
1366      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1367      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1368      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1369        of surface winds for the cube
1370      (A verification experiment, based on global_ocean.cs32x15, but with
1371       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1372       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1373       complete with example surface forcing files and matlab scripts to look
1374       at the output and compare it with that of global_ocean.cs32x15.)
1375    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1376       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1377       to conform to the common rule.
1378    o check-in the first version of the coupler + interfaces for multi-components
1379       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1380       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1381       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1382       - ocean and atmos. share the same horizontal grid (no interpolation).
1383       - exchanges between component and coupler is done in forward_step
1384    o new verification experiment, cpl_aim+ocn:
1385       coupled ocean - AIM atmosphere on cs32 grid.
1386    
1387    checkpoint52d_pre
1388    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1389    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1390    
1391    checkpoint52c_post
1392    o Fixing OPTIONS files for use of exf:
1393      - ALLOW_ECCO not needed
1394      - ECCO_CPPOPTIONS.h should not be included from
1395        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1396        as has been the case in the past
1397      - All cal/exf related options are currently set in
1398        single header file. Should remain so until we
1399        agree on a consistent new policy.
1400    o Removed all CPP options for cal package.
1401      cal has no more CPP options.
1402    o modified STOREs in GAD_ADVECTION
1403    o corrected key comp. for passkey
1404    
1405    checkpoint52b_post
1406    o new version: "thsice" of thermodynamic sea-ice pkg:
1407     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1408     - modify fluxes but do not change theta directly;
1409     - light cleaning of bulk_force pkg (still needed with thsice).
1410     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1411       + output_thsice.txt to test thsice & bulk_force pkgs.
1412    o put back grid & coriolis monitor output.
1413    checkpoint52b_pre
1414    
1415    o call "do_the_model_io" at the beginning (=> dump initial state)
1416    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1417    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1418      (need info on NUMBER_OF_PTRACERS)
1419    o missing PTRACERS headers in some routines
1420    o default tamc.h in pkg/autodiff supposed to crash
1421      to ensure proper customization
1422    
1423    checkpoint52a_post
1424    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1425      - moved surfaceTendencyTice from pkg/seaice to main code
1426      - subroutine FREEZE_SURFACE now limits only surface temperature
1427        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1428        => new output.txt for global_ocean.cs32x15 & global_with_exf
1429      - keep the old version of FREEZE for backward compatibility;
1430        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1431      - corresponding modifs for TAF directives
1432    o added surface flux output variables to TIMEAVE_STATVARS
1433    o time-averaged output for pkg/ptracers
1434    o fix problem with ECCO-related divided adjoint
1435      snapshot file was missing some ad-variables,
1436      but no warning issued by TAF
1437    
1438    checkpoint52a_pre
1439    o some bug fixes for #undef REAL4_IS_SLOW
1440    
1441    checkpoint52 = ecco_c52_e35
1442    o after testing adjoints of checkpoint51u_post
1443    
1444    checkpoint51u_post
1445    o this is the post-merge tag of the ecco-branch
1446      (needs another clean checkout and re-testing)
1447    o various natl_box_adjoint configs and results
1448      but no input fields
1449    o obcs adjoint not yet merged!
1450    o adding ECCO global 1x1 and 2x2 degree configs
1451    o updated/extended some store directives for seaice
1452    o pkg/ecco now containes ecco-specific part of cost function
1453    o top level routines the_main_loop, forward_step
1454      supersede those in model/src/
1455      previous input data.cost now in data.ecco
1456      (new namelist ecco_cost_nml)
1457    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1458    
1459    checkpoint51t_post
1460    o this is the pre-merge tag of the ecco-branch
1461    
1462    checkpoint51s_post
1463    o cleanup: removed various obsolete #define-s
1464    o pkg/grdchk
1465      - renamed 'ph-grd 3' to 'grad-res'
1466      - merged from ecco-branch
1467        (remaining bug fixes for obcs gradient checks)
1468      - additional high-precision output for testreport
1469        (grep for 'precision_grdchk_result')
1470    
1471    checkpoint51r_post
1472    o cleaned up or removed CPP_OPTIONS.h files
1473    o updated results for some of the tests to reflect the new
1474      optfiles (-ieee: -O0 instead of -O3)
1475    
1476    checkpoint51q_post
1477    o cd_code:
1478      - moved cd_scheme.F -> cd_code_scheme.F
1479      - separate read_checkpoint from cd_code_ini_vars.F
1480      - separated cd_code part from write_checkpoint
1481      - updated AD_SOURCE, generated .flow
1482      - added CD_CODE_VARS.h to the_main_loop
1483      - Moving cd_code specific store dir.s to pkg/cd_code
1484    o ctrl package totally restructured
1485      - pack/unpack now optional and decoupled from
1486        xx_/adxx_ I/O
1487      - ctrl_pack/unpack cleaned
1488        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)

1490    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1491    
1492    checkpoint51p_post
1493    o create initial cd_code package
1494      - WARNING: the initialization of fields within packages
1495        is broken because INI_FIELDS (where READ_CHECKPOINT is
1496        called) is called *before* PACKAGES_INIT_VARIABLES.
1497        This seems to be backwards since
1498        1) its important to initially zero the entire field including
1499           the "halo" region
1500        2) zeroing needs to be done *before* reading pickup info
1501           and the pickup call might or might not happen in any
1502           particular run
1503      - this needs an overhaul for R2
1504    o cleanup verification/*/code/GMREDI_OPTIONS.h
1505    o cleanup testreport
1506    
1507    checkpoint51o_post

1539      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1540      - subroutine FREEZE now limits only surface temperature
1541        (this means new output.txt for global_ocean.90x40x15,
1542         global_ocean.cs32x15, and global_with_exf)
1543    o added surface flux output variables to TIMEAVE_STATVARS

1632    o Added on-the-fly spatial interpolation capability
1633        "USE_EXF_INTERPOLATION" to pkg/exf.
1634      - This is a temporary Cartesian-grid hack until
1635        the super-duper ESMF coupler becomes available.
1636      - See verification/global_with_exf/README for usage example.
1637      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1638        flags and modified pkg/seaice accordingly.
1639    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1640        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1641        non-local transport term.
1642    
1643    checkpoint51e_post
1644    o pkg/mom_vecinv:
1645      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1657    o modif's to restore TAMC compatibility
1658      - avoid "_d" constructs in PARAMETER declarations
1659      - avoid interrupting lines by comment lines
1660    o Use cluster local disks for purely local I/O

1662      (merged from ecco-branch)
1663      - new active_file_loc... and mdsio_..._loc routines
1664      - affected packages: autodiff, ctrl, grdchk, mdsio
1665    
1666    checkpoint51c_post
1667    o introducing integer flag debugLevel
1668      - debLevZero: suppress all output
1669      - debLevA: standard
1670      - debLevB: equivalent to current debugMode=.TRUE.
1671    o introducing pathname variable mdsioLocalDir for mdsio
1672      that can be specified at runtime
1673      (relevant for cluster I/O to local disk)
1674    `
1675    >>>checkpoint51b_post
1676    adjoint of ptracers
1677    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1678    o extended state in checkpoint_lev?, etc.
1679    o alternative ctrl/cost with tr1 or ptracer
1680    o new comlev1_bibj_ptracers
1681    o new ptracers.flow
1682    o made ptracers_forcing same as external_forcing_s
1683    o added verification for adjoint with ptracers
1684      - adm. grdchk fail so far
1685      - tlm. grdchk OK
1686      - checked tapelev/comlev recomputations: OK
1687    <<<checkpoint51b_pre
1688    
1689    checkpoint51a_post
1690    o added code for biogeochemistry package
1691      - new pkgs: dic, gchem
1692      - new subroutine in ptracers
1693    o modify code for biogeo packages
1694      - in model/src and pkg/ptracers
1695    
1696    checkpoint51
1697    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1698      - autodiff, ctrl, exf, grdchk, seaice
1699      kept separate packages
1700      - cost, ecco, obcs
1701    o updating verification/internal_wave, verification/lab_sea
1702      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1703    
1704    checkpoint50i_post
1705    o Preparing next differentiable checkpoint and sync
1706      of MAIN vs. ecco-branch
1707      - 1st step: this one is differentiable
1708      - 2nd step: next(! not this) checkpoint will have updated packages
1709                  from ecco-branch)
1710    
1711    checkpoint50h_post
1712    o new package "land": provide surface BC for AIM.
1713    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1714    o AIM: use true log-P extrapolation for near surface temp (= as in
1715        F.Molteni paper) ; update aim.5l_cs output.
1716    o New variable in PARM03 for more flexible pickups
1717    o somewhat cleaned package initialisation sequence for
1718      ctrl/ cost/ ecco/ in packages_... routines
1719    
1720    checkpoint50g_post
1721    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1722      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1723      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1724        made the default because of faster convergence than ADI
1725    
1726    checkpoint50f_post
1727    o exf totally restructured
1728      - replaced all exf_set_ routines by one generic exf_set_gen.F
1729        and made sure it's still differentiable
1730      - split exf_getffields.F into new exf_bulkformulae.F
1731      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1732      - updated adjoint/makefile and relevant verif. accordingly
1733    
1734    checkpoint50f_pre

1742     o removed lots of single quotes from comments
1743    
1744    checkpoint50e_post
1745    o make KPP work with PTRACERS
1746     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1747       nearly a copy of kpp_transport_s
1748     - there is no analogue to SurfaceTendencyS, so I have to use
1749       gPtr(of the surface layer) instead
1750    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1751    checkpoint50e_pre
1752    
1753    checkpoint50d_post
1754    o change kpp output from multiple-record state files to single-record state
1755      files analogous to write_state.F
1756    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1757      analogous to the cg2d-related output.
1758    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1759      so that writing to internal file fn (with length 512) fails.
1760    checkpoint50d_pre
1761    
1762    checkpoint50c_post
1763    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1764    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1765    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1766    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1767    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1768    
1769    checkpoint50c_pre
1770    Merging from release1_p13:
1771    o bug fix for pkg/seaice dynamic solver
1772    o Added SEAICE_initialHEFF to pkg/seaice
1773    
1774    checkpoint50b_post
1775    o store u*,v* in gU,V instead of in guNm1,gvNm1
1776    o in order to put the momForcing out of the Adams-Bashforth:
1777      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1778      to timestep.F
1779    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1780    o re-generate output for highly sensitive test-exp:
1781       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1782    
1783    checkpoint50b_pre
1784    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1785    o corrected CPP option mismatch in exf_Bulk... functions for case
1786      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1787    
1788    checkpoint50a_post
1789    o Bug fix for merging between c50 and KPP.
1790      ikey was passed from thermodynamics to kpp_calc via
1791      common block rather than being recomputed in kpp_calc,
1792      in contradiction with new key itdkey.
1793      New key ikppkey created, and tamc.h headers updated.
1794    
1795    checkpoint50
1796    - 2nd step of merge with ecco-branch:
1797      merge changes in ecco-branch back into main trunk
1798    - bug fix in find_alpha
1799    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1800    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1801    - merged some sliced AD support routines
1802    
1803    checkpoint49
1804    merged from ecco-branch:
1805    o exf:
1806      - Enable initialisation of forcing fields to constant
1807        (runtime) values.
1808      - in exf_getffields.F
1809        Reduce i-/j-loop to interior domain, discarding overlaps.
1810        That also fixes wrong TAF-key computations for key_1, key_2
1811        with bulf formulae.
1812      - exf_init.F modify #ifdef for exf_init_evap
1813      - exf_getffieldrec.F, ctrl_getrec.F
1814        The following INT-usages are not safe:
1815          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1816          fldcount = int(fldsecs/fldperiod) + 1
1817        and were modified.
1818    o autodiff: checkpoint_lev...
1819      - updated storing for bulk formulae (some arrays were missing)
1820      - added state for seaice package
1821      - synchronized with main branch
1822    o DIVA:
1823      Modif.s in
1824      - the_main_loop.F
1825      - the_model_main.F
1826      and added cost_final_restore.F cost_final_store.F
1827      o With these changes, it is possible to fully separate
1828        the first forward run to compute the cost function (mdthe_main_loop)
1829        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1830        into separate model executions.
1831        This enables better tuning of DIVA to given queue sizes.
1832      o Loss of cost function value in consecutive DIVA runs is
1833        fixed by storing to 'costfinal' file.
1834      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1835        beginning/end of adjoint integration is accounted for.
1836      The current changes apply to TAF-1.4.26.
1837      TAF has one remaining bug, requiring one manual change
1838      (see MITgcm manual).
1839    o cal: synchronized between MAIN and ecco-branch
1840    
1841    checkpoint48i_post
1842    o Changes to restore differentiability of code w.r.t. previous tag
1843      (mostly adding new routines to make list and replacing
1844      pressure by totPhiHyd).
1845    o Updated and merged grdchk package
1846      - has both ADM and TLM checks
1847      - works for single- and multi-proc.
1848      - output cleaned
1849      - worked successfully for parallel DIVA
1850    o genmake:
1851      - Adding -platform=SP4
1852      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1853    o Modif. for DIVA:
1854      ctrl_unpack should not be called in intermediate DIVA interval.
1855      (similar thing would apply for active files such as
1856      tbar, sbar, psbar, which should not be reinitialised;
1857      only relevant for ecco-branch)
1858    
1859    checkpoint48h_post
1860    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1861    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1862    o Added SEAICE_initialHEFF to pkg/seaice
1863    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1864    
1865    checkpoint48g_post
1866    --- EOS:
1867    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1868      store total Potential in totPhyHyd for diagnostics & EOS.
1869    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1870    --- Pressure/geopotential gradient:
1871    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1872    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1873      ( changes results of global_ocean_pressure )
1874    o NLFS + z-coord.: add eta*Rho' contribution.
1875    o accurate phiHyd when using interface-W at the middle between 2 centers
1876     ( changes results of ideal_2D_oce )
1877    o includes r* 2nd term in potential gradient.
1878    
1879    checkpoint48f_post
1880    Merging from release1_p12:
1881    o Modifications for using pkg/exf with pkg/seaice

1885      - updated verification/global_with_exf/results/output.txt
1886    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1887      (SBO) core products, including oceanic mass, center-of-mass,
1888      angular, and bottom pressure (see pkg/sbo/README.sbo).
1889    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1890      to avoid negative values in shallow regions.
1891      - updated verification/natl_box/results/output.txt
1892      - updated verification/lab_sea/results/output.txt
1893    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1894    o Added useSingleCpuIO option (see PARAMS.h).
1895    o Updated useSingleCpuIO option in mdsio_writefield.F to
1896      work with multi-field files, e.g., for single-file pickup.
1897    o pkg/seaice:
1898      - bug fix in growth.F: QNET for no shortwave case
1899      - added HeffFile for specifying initial sea-ice thickness
1900      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1901    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1902      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1903    o pkg/seaice:
1904      - adjoint-friendly modifications
1905      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1906    
1907    checkpoint48e_post
1908    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1909    o dynamics: change definition of computational domain & adapt mom_fluxform
1910      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1911    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1912        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1913        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1914        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1915        inverted_barometer solid-body.cs-32x32x1
1916      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1917    
1918    checkpoint48d_post
1919    o in preparation for r*:
1920     a) use pre-computed gradient of hydrostatic potential:
1921        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1922     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1923        => affects results of glob_oce_pressure (different truncation error)  
1924      update output.txt of ideal_2D_oce & global_ocean_pressure
1925    
1926    checkpoint48d_pre
1927    o in preparation for r*:
1928      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1929      pass the 2 comp. of the grad. as arguments to momentum S/R.
1930      but for the moment, only used if it does not change the results.
1931    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1932    
1933    checkpoint48c_post
1934    Modifications in treatment of initial flux forcing controls
1935    to avoid extra storing of flux fields.
1936    
1937    checkpoint48c_pre
1938    o Added tidal_basin_2d experiment (currently 1D!)
1939    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1940    
1941    checkpoint48b_post
1942    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1943     (modification to pressure gradient not yet implemented)
1944    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1945      (for U & V) that are used for vertical advection of momentum.
1946    
1947    checkpoint48a_post
1948    o In preparation for r*, use temp. array to compute vertical transport
1949       in flux-form momentum pkg. => change results of few test-exp.
1950      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1951                        lab_sea, natl_box & plume_on_slope
1952    
1953    checkpoint48
1954    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1955    
1956    checkpoint47j_post
1957    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1958    o moved adexch from forward_step to addummy_in_stepping
1959    o added exch in ctrl_map_...
1960    o aveFreq.=0. at end of cost_final to avoid overwrite in
1961      reverse checkpointing loop
1962    o Yet more changes in gmredi:
1963      * adgmredi_calc_tensor
1964        avoiding all recomputation of gmredi_slope_limit
1965      * adgmredi_x/y/rtransport
1966        added flag for excessive storing to avoid recomp. of
1967        u/v/rtans, dTdx/y/z
1968        -> this is not really necessary and very memory-consuming
1969      * adgmredi_slope_psi:
1970        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1971      * gmredi_slope_limit
1972        re-activated full calculation of taperfct for case 'ac02'
1973    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1974    
1975    checkpoint47i_post
1976    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1977    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1978      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1979    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1980    o gmredi: fix few bugs.
1981    
1982    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1983    This will be a good checkpoint to plug into the ecco-branch.
1984    o few modif.'s to get latest version adjointed
1985      (mainly kick out code in ini_linear_phisurf)
1986    o modif's to run adjoint with exactConserv
1987    o case GM_BOLUS_ADVEC should be cleaned
1988      S/R gmredi_slope_psi should be cleaned
1989    o verification/carbon now has exactConserv=.TRUE.
1990    
1991    checkpoint47g_post
1992    o time-average AIM output: becomes independent from statvars time-average
1993      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1994    o After TAF bug fix:
1995      Tested adjoint of gmredi package.
1996      Tests were done with checkpoint47 rather than with latest
1997      checkpoint47f_post since the latter is broken for the adjoint
1998      verification/carbon/ contains both ADM and TLM gradient checks.
1999    Here they are, before they get changed/lost/stolen.
2000    Mostly modif.'s to fix numerical sensitivities.
2001    Gradient checks OK for
2002    - GM_taper_scheme:
2003      * clipping
2004      * ac02
2005      * linear
2006      * glw91
2007      * dm95
2008      * ldd97
2009    - GMREDI_OPTIONS:
2010      * GM_VISBECK_VARIABLE_K
2011      * GM_NON_UNITY_DIAGONAL
2012      * GM_EXTRA_DIAGONAL
2013      * GM_BOLUS_ADVEC
2014    in conjunction with data.gmredi parameters to be checked in
2015    in a few minutes under verification/carbon/code/
2016    
2017    checkpoint47f_post
2018    Merging from release1_p10:
2019    o modifications for using pkg/exf with pkg/seaice
2020      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
2021        and SEAICE_EXTERNAL_FLUXES
2022      - pkg/exf CPP options EXF_READ_EVAP and
2023        EXF_NO_BULK_COMPUTATIONS
2024      - usage examples are Experiments 8 and 9 in
2025        verification/lab_sea/README
2026      - verification/lab_sea default experiment now uses
2027        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
2028    
2029    checkpoint47e_post
2030    o created a tag prior to creating a branch
2031    
2032    checkpoint47d_post
2033    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
2034      at the bottom boundary had an erroneous half slip boundary condition
2035    o added bottom drag and no slip boundary condition capabilities to
2036      oceanic pressure coordinates code
2037    o added new verification experiment global_ocean_pressure, this experiment is
2038      also described in the tutorial section of the manual
2039    checkpoint47d_pre
2040    
2041    checkpoint47c_post
2042    o Added a verification experiment for a global cubed-sphere ocean run
2043      -  verification/global_ocean.cubed32x32x30
2044      -  uses pkg/therm_seaice and pkg/bulk_forcing
2045    
2046    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
2047    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
2048      when using P-coordinate; only implemented for atmospheric config.
2049    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
2050      NOTES: requires option NONLIN_FRSURF to be "#define".
2051    o update advect_xz/results/output.txt (left from checkpoint44g_post)
2052    
2053    checkpoint47b_post
2054    Merging from release1_p9:
2055    o pkg/seaice
2056      - removed GOTO's and added taf directives
2057      - double precision constants to reduce the g77 (Linux)
2058        to F77 (SGI) differences reported in release1_p8
2059    o tools/genmake
2060      - added SGI options
2061    o verification/testscript
2062      - updated to that of checkpoint47a_post
2063    o verification/global_ocean.90x40x15/input/eedata
2064      - modified for SGI f77 compatibility
2065    o verification/lab_sea
2066      - added description of sea-ice model
2067      - added missing matlab routines
2068      - added test of thermodynamics parallelization
2069    
2070    checkpoint47a_post
2071    o new pkg: aim_v23
2072     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
2073       for now, keep the same surface forcing as before.
2074     - Part-Cell implemented into AIM; check that Heat & Water are conserved
2075     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
2076     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
2077    o add diagnostic of surface correction term in monitor output
2078    
2079    o bulk_force and therm_seaice
2080    - Two packages:  bulk_force (Bulk forcing)
2081      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
2082    - Earlier integration from Stephaine Dutkiewicz
2083      and Patrick Heimbach.
2084    - Two ifdef statements for compile time,
2085       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
2086    
2087    checkpoint47
2088    differentiable version of checkpoint46n_post
2089    o bug fix in quasihydrostaticterms
2090    o * "clean" adjoint code (in terms of extensive recomputations)
2091        can now be obtained for all GMREDI options (i.e. for
2092        - GM_VISBECK_VARIABLE_K
2093        - GM_NON_UNITY_DIAGONAL
2094        - GM_EXTRA_DIAGONAL
2095        - GM_BOLUS_ADVEC )
2096      * However, wrong gradient check problem remains unsolved.
2097      * New CPP options have been introduced for different
2098        tapering schemes
2099    o external_fields_load now part of differentiation list
2100    o pressure needs multiple storing;
2101      would be nice to have store_pressure at beginning or
2102      end of forward_step, e.g. by having phiHyd global (5-dim.)
2103      (NB: pressure is needed for certain cases in find_rho,
2104      which is also invoked through convective_adjustment).
2105    o recomputations in find_rho for cases
2106     'JMD95'/'UNESCO' or 'MDJWF' are OK.
2107    o #define ATMOSPHERIC_LOADING should be differentiable
2108    o ini_forcing shifted to begining of initialise_varia
2109    o Incorporating QNVS line search routines into MITgcm
2110      (this is separate code, and therefore not under pkg)
2111      lsopt/, optim/
2112    o Updated verification/carbon/
2113      - #define GM_VISBECK_VARIABLE_K
2114      - GM_taper_scheme    = 'ldd97'    
2115    
2116    checkpoint46n_post
2117    Merging from release1_p8:
2118    o verification/natl_box:
2119      updating new external_fields_load routine
2120    o New package: pkg/seaice
2121      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
2122      The sea-ice code is based on Hibler (1979-1980).
2123      Two sea-ice dynamic solvers, ADI and LSR, are included.
2124      In addition to computing prognostic sea-ice variables and diagnosing
2125      the forcing/external data fields that drive the ocean model,
2126      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2127      The implied surface heat flux is then stored in variable
2128      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2129      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2130      non-local transport term.  Because this call precedes model
2131      thermodynamics, temperature under sea-ice may not be "exactly" at
2132      the freezing point by the time theta is dumped or time-averaged.
2133      N.B.: fairly large differences in accuracy occur across
2134            different platforms/compilers; comparison between
2135            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2136            generated output gives:
2137       T           S           U           V
2138      C D M    c        m  s        m  s        m  s        m  s
2139      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
2140      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
2141      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
2142    
2143      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2144    o GAD:
2145      - generated new common blocks to account for call of
2146        same gad routines with differing traceridentities
2147        (needed to modify tracerIdentity indices in GAD.h)
2148      - generated separate common blocks for case useCubedSphereExchange
2149        (Department of Futurology)
2150      - parameter lists to gmredi_?transport: added tracerIdentity
2151      - added new key indices to tamc.h
2152    o external_fields_load:
2153      - added this routine to TAF list
2154      - needed to make some common blocks global and additional storing
2155        along the same lines as exf package (checkpoint_lev?_directives.h)
2156    o exf:
2157      updated external forcing package
2158      - bug fixes carried over from ecco-branch
2159        (missing OBCS_OPTIONS.h in two routines)
2160      - enable easy to use "no forcing".
2161      - added exf I/O for atmospheric loading
2162      - added exf I/O for runoff data
2163      - transfered scaling between exf <-> MITgcm to exf namelist
2164    o Adding new verification experiment global_with_exf.
2165      This verification experiment is almost identical to the
2166      global_ocean.90x40x15 experiment, except that it uses
2167      the exf (and cal) package instead of the
2168      external_fields_load routine (cf README file).
2169    
2170    checkpoint46m_post
2171    o modified testscript to return -- when there are no lines of "%MON" output
2172    o added new flag "quasiHydrostatic" for QH mode
2173      and new routine quasihydrostaticterms()
2174    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2175      New routine: mom_u_coriolis_nh()
2176    o fixed sign of non-hydrostatic metric terms in u and v equations.
2177      Depend on correct sign of gravitySign.
2178    o added work.pc* to .cvsignore in aim directories using ifc
2179    o introduced flag for controllin non-hydrostatic metric terms
2180    o removed gravitySign from PARM04
2181    o switched to g77/ifc from pgf77 in aim experiments
2182    
2183    checkpoint46l_post
2184    o made convective adjustment work with pressure coordinates:
2185     - changed the direction of k-loop in convective_adjustment.F for the
2186       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2187     - adjusted the reference pressure k-index in convective_adjustment.F
2188     - adjusted the convection condition in convect.F (in analogy to
2189       calc_ivdc.F)
2190     - convective_adjustment no longer computes anything on the halos
2191     - removed the warnings about negative salinity from find_rho.F and
2192       find_alpha.F; instead the new routine look_for_neg_salinity, called
2193       at the beginning of find_rho, find_alpha, and find_beta, does a
2194       check of the entire slice, if CPP-option
2195       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2196    checkpoint46l_pre
2197    
2198    checkpoint46k_post
2199    o fixed the verification/global_ocean.90x40x15 experiment:
2200     - new bathymetry (the world according to A., JMC, and M.)
2201     - new initial fields and forcing fields (*.bin files)
2202     - new POLY3.COEFFS (for the next release one should switch to a full
2203       equation of state: JMD95P or MDJWF)
2204     - fixed several errors and redundancies in the data file
2205     - experiment uses looped cells
2206     - added matlab directory with diagnostic scripts for plotting of output
2207    
2208    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2209     - read AIM physics parameters from a file (data.aimphys)
2210     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2211    
2212    checkpoint46j_post
2213    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2214    o move wVel computation at the end of the time step, in S/R integr_continuity
2215    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2216    o update timeave pkg for wVel diagnostic.
2217    checkpoint46j_pre
2218    
2219    checkpoint46i_post
2220    o Clean up AIM package (and keep the results unchanged):
2221      include CPP_OPTION and use IMPLICT NONE in all routines ;
2222      declare all the variables _RL ; use _d 0 for all numerical constants.
2223      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2224    
2225    checkpoint46h_post
2226    o cleaned up the use of rhoNil and rhoConst.
2227      - rhoNil should only appear in the LINEAR equation of state, everywhere
2228        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2229        and the dynamical equations are all divided by rhoConst
2230    o introduced new parameter rhoConstFresh, a reference density of fresh
2231      water, to remove the fresh water flux's dependence on rhoNil. The default
2232      value is 999.8 kg/m^3
2233    o cleanup up external_forcing.F and external_forcing_surf.F
2234      - can now be used by both OCEANIC and OCEANICP
2235    checkpoint46h_pre
2236    
2237     Added code to convert surface volume flux (fresh water) into
2238     a mass flux when using P coordinates in the ocean (OCEANICP).
2239     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2240    
2241    checkpoint46g_post
2242    o Include a new diagnostic variable phiHydLow for the ocean model
2243      - in z-coordinates, it is the bottom pressure anomaly
2244      - in p-coordinates, it is the sea surface elevation
2245      - in both cases, these variable have global drift, reflecting the mass
2246        drift in z-coordinates and the volume drift in p-coordinates
2247      - included time averaging for phiHydLow, be aware of the drift!
2248    o depth-dependent computation of Bo_surf for pressure coordinates
2249      in the ocean (buoyancyRelation='OCEANICP')
2250      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2251        Theta, Salinity, and Pressure in the parameter list. This routine is
2252        presently contained in find_rho.F. This routine does not give the
2253        correct density for 'POLY3', which would be a z-dependent reference
2254        density.
2255    o cleaned up find_rho
2256      - removed obsolete 'eqn' from the parameter list.
2257    o added two new verification experiments: gop and goz
2258      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2259    checkpoint46g_pre
2260    
2261    checkpoint46f_post
2262    o Enable tangent linear (forward mode) gradient checks:
2263      - extended active file handling to g_... files
2264      - added TANGENT_SIMULATION to theSimulationMode
2265      - extended grdchk package accordingly
2266    o added tangent linear setup in verification/carbon/code_ftl
2267    o added adjoint setup in verification/front_relax/code_ad
2268    
2269    checkpoint46e_post
2270    o Added new equation of state -> MDJWF
2271      - EOS of McDougall et al., 2002, JAOT, submitted
2272      - caveat: the equation of state is only valid for a smaller (more
2273        realistic?) range of values than JMD95P/Z and UNESCO
2274      - added masks to the calculation of pressure in store_pressure
2275      - added more check values for density in check_eos (ini_eos.F), some of
2276        the old check values are out of the range of the MDJWF-eos, so don't
2277        expect perfect matches for those
2278    checkpoint46e_pre
2279    
2280    checkpoint46d_post
2281    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2282      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2283      case of pressure coordinates. eosType='JMD95Z' in
2284      combination with buoyancyRelation='OCEANICP' now causes an error.
2285    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2286      in find_alpha/beta.
2287    checkpoint46d_pre
2288    
2289    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2290      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2291    
2292    checkpoint46c_post
2293    o Changes necessary for ocean in p-coordinates
2294     -  Added new buoyancy relation = 'OCEANICP'
2295     -  Added new parameters = gravitySign (this used to be contained inside
2296        the factor dRdZ which I added when we first switched to R coordinates).
2297     X GM/Redi is not compatible (yet)
2298     X bottom drag and no-slip need to be debugged.
2299    checkpoint46c_pre
2300    
2301    checkpoint46b_post
2302    o Added new equation of state -> JMD95Z and JMD95P
2303      - EOS of Jackett and McDougall, 1995, JAOT
2304      - moved all EOS parameters into EOS.h
2305      - new routines ini_eos.F, store_pressure.F
2306    o Added UNESCO EOS, but not recommended because it requires
2307      in-situ temperature (see JMD95)
2308    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2309      unesco.f to be used with POLY3
2310    checkpoint46b_pre
2311    
2312    checkpoint46a_post
2313    o Added (atmospheric) pressure loading
2314      - new field in FFIELDS.h, etc...
2315      - new cpp flag ATMOSPHERIC_LOADING
2316    o Changed hFacC to _hFacC in calc_phi_hyd.F
2317    o Added SHORTWAVE_HEATING to some files for consistency
2318    checkpoint46a_pre
2319    
2320    checkpoint46
2321    further merges from release1_p5
2322    o new ctrl package
2323      - adopted from ECCO environment to enable optimization
2324      - added Eliassen Palm fluxes to controls
2325    o added Eliassen Palm flux controls to gradient check package
2326    o cost package
2327      - Compatible with new ctrl package
2328      - added Eliassen Palm cost hooks
2329      - modif's of existing cost functions
2330    o Adjoint-related bug fixes in kpp:
2331      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2332      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2333    o autodiff package
2334      - flow directives:
2335        + new for S/R do_the_model_io
2336        + enhanced for S/R checkpoint
2337        + new gmredi.flow
2338      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2339        disable adcommon.h/g_common.h by default.
2340      - fixed problem for adjoint of global_max
2341    o modified verification/carbon/
2342    o New setup for adjoint of global_ocean
2343    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2344    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2345    o incorporated hooks for sponge layer code (external_forcing.F)
2346    
2347    checkpoint45d_post
2348    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2349    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2350      (affects plume_on_slope "cg2d" output)
2351    o add new parameter deltaTfreesurf for free-surface time stepping
2352    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2353  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
