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

1171     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1172    checkpoint52e_pre
1173    
1174    o fix bug in impldiff when Nr=1 or Nr=2.
1175    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1176    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1177    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1178      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1179    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1180    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1181    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations

1192      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1193      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1194        of surface winds for the cube
1195      (A verification experiment, based on global_ocean.cs32x15, but with
1196       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1197       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1198       complete with example surface forcing files and matlab scripts to look
1199       at the output and compare it with that of global_ocean.cs32x15.)
1200    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1201       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1202       to conform to the common rule.
1203    o check-in the first version of the coupler + interfaces for multi-components
1204       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1205       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1206       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1207       - ocean and atmos. share the same horizontal grid (no interpolation).
1208       - exchanges between component and coupler is done in forward_step
1209    o new verification experiment, cpl_aim+ocn:
1210       coupled ocean - AIM atmosphere on cs32 grid.
1211    
1212    checkpoint52d_pre
1213    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1214    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1215    
1216    checkpoint52c_post
1217    o Fixing OPTIONS files for use of exf:
1218      - ALLOW_ECCO not needed
1219      - ECCO_CPPOPTIONS.h should not be included from
1220        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1221        as has been the case in the past
1222      - All cal/exf related options are currently set in
1223        single header file. Should remain so until we
1224        agree on a consistent new policy.
1225    o Removed all CPP options for cal package.
1226      cal has no more CPP options.
1227    o modified STOREs in GAD_ADVECTION
1228    o corrected key comp. for passkey
1229    
1230    checkpoint52b_post
1231    o new version: "thsice" of thermodynamic sea-ice pkg:
1232     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1233     - modify fluxes but do not change theta directly;
1234     - light cleaning of bulk_force pkg (still needed with thsice).
1235     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1236       + output_thsice.txt to test thsice & bulk_force pkgs.
1237    o put back grid & coriolis monitor output.
1238    checkpoint52b_pre
1239

1242    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1243      (need info on NUMBER_OF_PTRACERS)
1244    o missing PTRACERS headers in some routines
1245    o default tamc.h in pkg/autodiff supposed to crash
1246      to ensure proper customization
1247    
1248    checkpoint52a_post
1249    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1250      - moved surfaceTendencyTice from pkg/seaice to main code
1251      - subroutine FREEZE_SURFACE now limits only surface temperature
1252        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1253        => new output.txt for global_ocean.cs32x15 & global_with_exf
1254      - keep the old version of FREEZE for backward compatibility;
1255        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1256      - corresponding modifs for TAF directives
1257    o added surface flux output variables to TIMEAVE_STATVARS

1263    checkpoint52a_pre
1264    o some bug fixes for #undef REAL4_IS_SLOW
1265    
1266    checkpoint52 = ecco_c52_e35
1267    o after testing adjoints of checkpoint51u_post
1268    
1269    checkpoint51u_post
1270    o this is the post-merge tag of the ecco-branch
1271      (needs another clean checkout and re-testing)
1272    o various natl_box_adjoint configs and results
1273      but no input fields
1274    o obcs adjoint not yet merged!
1275    o adding ECCO global 1x1 and 2x2 degree configs
1276    o updated/extended some store directives for seaice

1281      (new namelist ecco_cost_nml)
1282    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1283    
1284    checkpoint51t_post
1285    o this is the pre-merge tag of the ecco-branch
1286    
1287    checkpoint51s_post
1288    o cleanup: removed various obsolete #define-s
1289    o pkg/grdchk
1290      - renamed 'ph-grd 3' to 'grad-res'
1291      - merged from ecco-branch
1292        (remaining bug fixes for obcs gradient checks)
1293      - additional high-precision output for testreport
1294        (grep for 'precision_grdchk_result')
1295    
1296    checkpoint51r_post
1297    o cleaned up or removed CPP_OPTIONS.h files
1298    o updated results for some of the tests to reflect the new
1299      optfiles (-ieee: -O0 instead of -O3)
1300    
1301    checkpoint51q_post
1302    o cd_code:
1303      - moved cd_scheme.F -> cd_code_scheme.F
1304      - separate read_checkpoint from cd_code_ini_vars.F
1305      - separated cd_code part from write_checkpoint

1315    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1316    
1317    checkpoint51p_post
1318    o create initial cd_code package
1319      - WARNING: the initialization of fields within packages
1320        is broken because INI_FIELDS (where READ_CHECKPOINT is
1321        called) is called *before* PACKAGES_INIT_VARIABLES.
1322        This seems to be backwards since
1323        1) its important to initially zero the entire field including
1324           the "halo" region
1325        2) zeroing needs to be done *before* reading pickup info
1326           and the pickup call might or might not happen in any
1327           particular run
1328      - this needs an overhaul for R2
1329    o cleanup verification/*/code/GMREDI_OPTIONS.h

1364      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1365      - subroutine FREEZE now limits only surface temperature
1366        (this means new output.txt for global_ocean.90x40x15,
1367         global_ocean.cs32x15, and global_with_exf)
1368    o added surface flux output variables to TIMEAVE_STATVARS

1519      - in model/src and pkg/ptracers
1520    
1521    checkpoint51
1522    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1523      - autodiff, ctrl, exf, grdchk, seaice
1524      kept separate packages
1525      - cost, ecco, obcs
1526    o updating verification/internal_wave, verification/lab_sea
1527      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1528    
1529    checkpoint50i_post
1530    o Preparing next differentiable checkpoint and sync
1531      of MAIN vs. ecco-branch
1532      - 1st step: this one is differentiable
1533      - 2nd step: next(! not this) checkpoint will have updated packages
1534                  from ecco-branch)
1535    
1536    checkpoint50h_post
1537    o new package "land": provide surface BC for AIM.
1538    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1539    o AIM: use true log-P extrapolation for near surface temp (= as in
1540        F.Molteni paper) ; update aim.5l_cs output.
1541    o New variable in PARM03 for more flexible pickups
1542    o somewhat cleaned package initialisation sequence for
1543      ctrl/ cost/ ecco/ in packages_... routines
1544    
1545    checkpoint50g_post
1546    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1547      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1548      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1549        made the default because of faster convergence than ADI
1550    
1551    checkpoint50f_post
1552    o exf totally restructured
1553      - replaced all exf_set_ routines by one generic exf_set_gen.F
1554        and made sure it's still differentiable
1555      - split exf_getffields.F into new exf_bulkformulae.F
1556      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1557      - updated adjoint/makefile and relevant verif. accordingly
1558    
1559    checkpoint50f_pre
1560     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1561          + change Evap over land. (update aim.5l_cs output)
1562     o added missing .cvsignores and made uniform across expts
1563     o changed configuration of tidal_basin_2d expt
1564     o added pkg/debug functions for tracing code in fatal crashes
1565     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1566     o new fn in pkg/monitor to stop model if solution grows too big
1567     o removed lots of single quotes from comments
1568    
1569    checkpoint50e_post
1570    o make KPP work with PTRACERS
1571     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1572       nearly a copy of kpp_transport_s
1573     - there is no analogue to SurfaceTendencyS, so I have to use
1574       gPtr(of the surface layer) instead
1575    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1576    checkpoint50e_pre
1577    
1578    checkpoint50d_post
1579    o change kpp output from multiple-record state files to single-record state
1580      files analogous to write_state.F
1581    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1582      analogous to the cg2d-related output.
1583    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1584      so that writing to internal file fn (with length 512) fails.
1585    checkpoint50d_pre
1586    
1587    checkpoint50c_post
1588    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1589    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1590    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1591    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1592    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1593    
1594    checkpoint50c_pre
1595    Merging from release1_p13:
1596    o bug fix for pkg/seaice dynamic solver
1597    o Added SEAICE_initialHEFF to pkg/seaice
1598    
1599    checkpoint50b_post
1600    o store u*,v* in gU,V instead of in guNm1,gvNm1
1601    o in order to put the momForcing out of the Adams-Bashforth:
1602      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1603      to timestep.F
1604    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1605    o re-generate output for highly sensitive test-exp:
1606       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1607    
1608    checkpoint50b_pre
1609    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1610    o corrected CPP option mismatch in exf_Bulk... functions for case
1611      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1612    
1613    checkpoint50a_post
1614    o Bug fix for merging between c50 and KPP.
1615      ikey was passed from thermodynamics to kpp_calc via
1616      common block rather than being recomputed in kpp_calc,
1617      in contradiction with new key itdkey.
1618      New key ikppkey created, and tamc.h headers updated.
1619    
1620    checkpoint50
1621    - 2nd step of merge with ecco-branch:
1622      merge changes in ecco-branch back into main trunk
1623    - bug fix in find_alpha
1624    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1625    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1626    - merged some sliced AD support routines
1627    
1628    checkpoint49
1629    merged from ecco-branch:
1630    o exf:
1631      - Enable initialisation of forcing fields to constant
1632        (runtime) values.
1633      - in exf_getffields.F
1634        Reduce i-/j-loop to interior domain, discarding overlaps.
1635        That also fixes wrong TAF-key computations for key_1, key_2
1636        with bulf formulae.
1637      - exf_init.F modify #ifdef for exf_init_evap
1638      - exf_getffieldrec.F, ctrl_getrec.F
1639        The following INT-usages are not safe:
1640          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1641          fldcount = int(fldsecs/fldperiod) + 1
1642        and were modified.
1643    o autodiff: checkpoint_lev...
1644      - updated storing for bulk formulae (some arrays were missing)
1645      - added state for seaice package
1646      - synchronized with main branch
1647    o DIVA:
1648      Modif.s in
1649      - the_main_loop.F
1650      - the_model_main.F
1651      and added cost_final_restore.F cost_final_store.F
1652      o With these changes, it is possible to fully separate
1653        the first forward run to compute the cost function (mdthe_main_loop)
1654        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1655        into separate model executions.
1656        This enables better tuning of DIVA to given queue sizes.
1657      o Loss of cost function value in consecutive DIVA runs is
1658        fixed by storing to 'costfinal' file.
1659      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1660        beginning/end of adjoint integration is accounted for.
1661      The current changes apply to TAF-1.4.26.
1662      TAF has one remaining bug, requiring one manual change
1663      (see MITgcm manual).
1664    o cal: synchronized between MAIN and ecco-branch
1665    
1666    checkpoint48i_post
1667    o Changes to restore differentiability of code w.r.t. previous tag
1668      (mostly adding new routines to make list and replacing
1669      pressure by totPhiHyd).
1670    o Updated and merged grdchk package
1671      - has both ADM and TLM checks
1672      - works for single- and multi-proc.
1673      - output cleaned
1674      - worked successfully for parallel DIVA
1675    o genmake:
1676      - Adding -platform=SP4
1677      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1678    o Modif. for DIVA:
1679      ctrl_unpack should not be called in intermediate DIVA interval.
1680      (similar thing would apply for active files such as
1681      tbar, sbar, psbar, which should not be reinitialised;
1682      only relevant for ecco-branch)
1683    
1684    checkpoint48h_post
1685    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1686    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1687    o Added SEAICE_initialHEFF to pkg/seaice
1688    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1689    
1690    checkpoint48g_post
1691    --- EOS:
1692    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1693      store total Potential in totPhyHyd for diagnostics & EOS.
1694    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1695    --- Pressure/geopotential gradient:
1696    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1697    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1698      ( changes results of global_ocean_pressure )
1699    o NLFS + z-coord.: add eta*Rho' contribution.
1700    o accurate phiHyd when using interface-W at the middle between 2 centers
1701     ( changes results of ideal_2D_oce )
1702    o includes r* 2nd term in potential gradient.
1703    
1704    checkpoint48f_post
1705    Merging from release1_p12:
1706    o Modifications for using pkg/exf with pkg/seaice
1707      - improved description of the various forcing configurations
1708      - added basic radiation bulk formulae to pkg/exf
1709      - units/sign fix for evap computation in exf_getffields.F
1710      - updated verification/global_with_exf/results/output.txt
1711    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1712      (SBO) core products, including oceanic mass, center-of-mass,
1713      angular, and bottom pressure (see pkg/sbo/README.sbo).
1714    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1715      to avoid negative values in shallow regions.
1716      - updated verification/natl_box/results/output.txt
1717      - updated verification/lab_sea/results/output.txt
1718    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1719    o Added useSingleCpuIO option (see PARAMS.h).
1720    o Updated useSingleCpuIO option in mdsio_writefield.F to
1721      work with multi-field files, e.g., for single-file pickup.
1722    o pkg/seaice:
1723      - bug fix in growth.F: QNET for no shortwave case
1724      - added HeffFile for specifying initial sea-ice thickness
1725      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1726    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1727      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1728    o pkg/seaice:
1729      - adjoint-friendly modifications
1730      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1731    
1732    checkpoint48e_post
1733    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1734    o dynamics: change definition of computational domain & adapt mom_fluxform
1735      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1736    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1737        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1738        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1739        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1740        inverted_barometer solid-body.cs-32x32x1
1741      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1742    
1743    checkpoint48d_post
1744    o in preparation for r*:
1745     a) use pre-computed gradient of hydrostatic potential:
1746        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1747     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1748        => affects results of glob_oce_pressure (different truncation error)  
1749      update output.txt of ideal_2D_oce & global_ocean_pressure
1750    
1751    checkpoint48d_pre
1752    o in preparation for r*:
1753      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1754      pass the 2 comp. of the grad. as arguments to momentum S/R.
1755      but for the moment, only used if it does not change the results.
1756    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1757    
1758    checkpoint48c_post
1759    Modifications in treatment of initial flux forcing controls
1760    to avoid extra storing of flux fields.
1761    
1762    checkpoint48c_pre
1763    o Added tidal_basin_2d experiment (currently 1D!)
1764    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1765    
1766    checkpoint48b_post
1767    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1768     (modification to pressure gradient not yet implemented)
1769    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1770      (for U & V) that are used for vertical advection of momentum.
1771    
1772    checkpoint48a_post
1773    o In preparation for r*, use temp. array to compute vertical transport
1774       in flux-form momentum pkg. => change results of few test-exp.
1775      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1776                        lab_sea, natl_box & plume_on_slope
1777    
1778    checkpoint48
1779    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1780    
1781    checkpoint47j_post
1782    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1783    o moved adexch from forward_step to addummy_in_stepping
1784    o added exch in ctrl_map_...
1785    o aveFreq.=0. at end of cost_final to avoid overwrite in
1786      reverse checkpointing loop
1787    o Yet more changes in gmredi:
1788      * adgmredi_calc_tensor
1789        avoiding all recomputation of gmredi_slope_limit
1790      * adgmredi_x/y/rtransport
1791        added flag for excessive storing to avoid recomp. of
1792        u/v/rtans, dTdx/y/z
1793        -> this is not really necessary and very memory-consuming
1794      * adgmredi_slope_psi:
1795        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1796      * gmredi_slope_limit
1797        re-activated full calculation of taperfct for case 'ac02'
1798    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1799    
1800    checkpoint47i_post
1801    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1802    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1803      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1804    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1805    o gmredi: fix few bugs.
1806    
1807    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1808    This will be a good checkpoint to plug into the ecco-branch.
1809    o few modif.'s to get latest version adjointed
1810      (mainly kick out code in ini_linear_phisurf)
1811    o modif's to run adjoint with exactConserv
1812    o case GM_BOLUS_ADVEC should be cleaned
1813      S/R gmredi_slope_psi should be cleaned
1814    o verification/carbon now has exactConserv=.TRUE.
1815    
1816    checkpoint47g_post
1817    o time-average AIM output: becomes independent from statvars time-average
1818      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1819    o After TAF bug fix:
1820      Tested adjoint of gmredi package.
1821      Tests were done with checkpoint47 rather than with latest
1822      checkpoint47f_post since the latter is broken for the adjoint
1823      verification/carbon/ contains both ADM and TLM gradient checks.
1824    Here they are, before they get changed/lost/stolen.
1825    Mostly modif.'s to fix numerical sensitivities.
1826    Gradient checks OK for
1827    - GM_taper_scheme:
1828      * clipping
1829      * ac02
1830      * linear
1831      * glw91
1832      * dm95
1833      * ldd97
1834    - GMREDI_OPTIONS:
1835      * GM_VISBECK_VARIABLE_K
1836      * GM_NON_UNITY_DIAGONAL
1837      * GM_EXTRA_DIAGONAL
1838      * GM_BOLUS_ADVEC
1839    in conjunction with data.gmredi parameters to be checked in
1840    in a few minutes under verification/carbon/code/
1841    
1842    checkpoint47f_post
1843    Merging from release1_p10:
1844    o modifications for using pkg/exf with pkg/seaice
1845      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1846        and SEAICE_EXTERNAL_FLUXES
1847      - pkg/exf CPP options EXF_READ_EVAP and
1848        EXF_NO_BULK_COMPUTATIONS
1849      - usage examples are Experiments 8 and 9 in
1850        verification/lab_sea/README
1851      - verification/lab_sea default experiment now uses
1852        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1853    
1854    checkpoint47e_post
1855    o created a tag prior to creating a branch
1856    
1857    checkpoint47d_post
1858    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1859      at the bottom boundary had an erroneous half slip boundary condition
1860    o added bottom drag and no slip boundary condition capabilities to
1861      oceanic pressure coordinates code
1862    o added new verification experiment global_ocean_pressure, this experiment is
1863      also described in the tutorial section of the manual
1864    checkpoint47d_pre
1865    
1866    checkpoint47c_post
1867    o Added a verification experiment for a global cubed-sphere ocean run
1868      -  verification/global_ocean.cubed32x32x30
1869      -  uses pkg/therm_seaice and pkg/bulk_forcing
1870    
1871    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1872    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1873      when using P-coordinate; only implemented for atmospheric config.
1874    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1875      NOTES: requires option NONLIN_FRSURF to be "#define".
1876    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1877    
1878    checkpoint47b_post
1879    Merging from release1_p9:
1880    o pkg/seaice
1881      - removed GOTO's and added taf directives
1882      - double precision constants to reduce the g77 (Linux)
1883        to F77 (SGI) differences reported in release1_p8
1884    o tools/genmake
1885      - added SGI options

1895    checkpoint47a_post
1896    o new pkg: aim_v23
1897     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1898       for now, keep the same surface forcing as before.
1899     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1900     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1901     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1902    o add diagnostic of surface correction term in monitor output
1903    
1904    o bulk_force and therm_seaice
1905    - Two packages:  bulk_force (Bulk forcing)
1906      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1907    - Earlier integration from Stephaine Dutkiewicz
1908      and Patrick Heimbach.
1909    - Two ifdef statements for compile time,
1910       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1911    
1912    checkpoint47
1913    differentiable version of checkpoint46n_post
1914    o bug fix in quasihydrostaticterms
1915    o * "clean" adjoint code (in terms of extensive recomputations)
1916        can now be obtained for all GMREDI options (i.e. for
1917        - GM_VISBECK_VARIABLE_K
1918        - GM_NON_UNITY_DIAGONAL
1919        - GM_EXTRA_DIAGONAL
1920        - GM_BOLUS_ADVEC )
1921      * However, wrong gradient check problem remains unsolved.
1922      * New CPP options have been introduced for different
1923        tapering schemes
1924    o external_fields_load now part of differentiation list
1925    o pressure needs multiple storing;
1926      would be nice to have store_pressure at beginning or
1927      end of forward_step, e.g. by having phiHyd global (5-dim.)
1928      (NB: pressure is needed for certain cases in find_rho,
1929      which is also invoked through convective_adjustment).
1930    o recomputations in find_rho for cases
1931     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1932    o #define ATMOSPHERIC_LOADING should be differentiable
1933    o ini_forcing shifted to begining of initialise_varia
1934    o Incorporating QNVS line search routines into MITgcm
1935      (this is separate code, and therefore not under pkg)
1936      lsopt/, optim/
1937    o Updated verification/carbon/
1938      - #define GM_VISBECK_VARIABLE_K
1939      - GM_taper_scheme    = 'ldd97'    
1940    
1941    checkpoint46n_post
1942    Merging from release1_p8:
1943    o verification/natl_box:
1944      updating new external_fields_load routine
1945    o New package: pkg/seaice
1946      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1947      The sea-ice code is based on Hibler (1979-1980).
1948      Two sea-ice dynamic solvers, ADI and LSR, are included.
1949      In addition to computing prognostic sea-ice variables and diagnosing
1950      the forcing/external data fields that drive the ocean model,
1951      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1952      The implied surface heat flux is then stored in variable
1953      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1954      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1955      non-local transport term.  Because this call precedes model
1956      thermodynamics, temperature under sea-ice may not be "exactly" at
1957      the freezing point by the time theta is dumped or time-averaged.
1958      N.B.: fairly large differences in accuracy occur across
1959            different platforms/compilers; comparison between
1960            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1961            generated output gives:
1962       T           S           U           V

1967    
1968      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1969    o GAD:
1970      - generated new common blocks to account for call of
1971        same gad routines with differing traceridentities
1972        (needed to modify tracerIdentity indices in GAD.h)
1973      - generated separate common blocks for case useCubedSphereExchange
1974        (Department of Futurology)
1975      - parameter lists to gmredi_?transport: added tracerIdentity
1976      - added new key indices to tamc.h
1977    o external_fields_load:
1978      - added this routine to TAF list
1979      - needed to make some common blocks global and additional storing
1980        along the same lines as exf package (checkpoint_lev?_directives.h)
1981    o exf:
1982      updated external forcing package
1983      - bug fixes carried over from ecco-branch
1984        (missing OBCS_OPTIONS.h in two routines)
1985      - enable easy to use "no forcing".
1986      - added exf I/O for atmospheric loading
1987      - added exf I/O for runoff data
1988      - transfered scaling between exf <-> MITgcm to exf namelist
1989    o Adding new verification experiment global_with_exf.
1990      This verification experiment is almost identical to the
1991      global_ocean.90x40x15 experiment, except that it uses
1992      the exf (and cal) package instead of the
1993      external_fields_load routine (cf README file).
1994    
1995    checkpoint46m_post
1996    o modified testscript to return -- when there are no lines of "%MON" output
1997    o added new flag "quasiHydrostatic" for QH mode
1998      and new routine quasihydrostaticterms()
1999    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2000      New routine: mom_u_coriolis_nh()
2001    o fixed sign of non-hydrostatic metric terms in u and v equations.
2002      Depend on correct sign of gravitySign.
2003    o added work.pc* to .cvsignore in aim directories using ifc
2004    o introduced flag for controllin non-hydrostatic metric terms
2005    o removed gravitySign from PARM04
2006    o switched to g77/ifc from pgf77 in aim experiments
2007    
2008    checkpoint46l_post
2009    o made convective adjustment work with pressure coordinates:
2010     - changed the direction of k-loop in convective_adjustment.F for the
2011       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2012     - adjusted the reference pressure k-index in convective_adjustment.F
2013     - adjusted the convection condition in convect.F (in analogy to
2014       calc_ivdc.F)
2015     - convective_adjustment no longer computes anything on the halos
2016     - removed the warnings about negative salinity from find_rho.F and
2017       find_alpha.F; instead the new routine look_for_neg_salinity, called
2018       at the beginning of find_rho, find_alpha, and find_beta, does a
2019       check of the entire slice, if CPP-option
2020       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2021    checkpoint46l_pre
2022    
2023    checkpoint46k_post
2024    o fixed the verification/global_ocean.90x40x15 experiment:
2025     - new bathymetry (the world according to A., JMC, and M.)
2026     - new initial fields and forcing fields (*.bin files)
2027     - new POLY3.COEFFS (for the next release one should switch to a full
2028       equation of state: JMD95P or MDJWF)
2029     - fixed several errors and redundancies in the data file
2030     - experiment uses looped cells
2031     - added matlab directory with diagnostic scripts for plotting of output
2032    
2033    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2034     - read AIM physics parameters from a file (data.aimphys)
2035     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2036    
2037    checkpoint46j_post
2038    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2039    o move wVel computation at the end of the time step, in S/R integr_continuity
2040    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2041    o update timeave pkg for wVel diagnostic.
2042    checkpoint46j_pre
2043    
2044    checkpoint46i_post
2045    o Clean up AIM package (and keep the results unchanged):
2046      include CPP_OPTION and use IMPLICT NONE in all routines ;
2047      declare all the variables _RL ; use _d 0 for all numerical constants.
2048      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2049    
2050    checkpoint46h_post
2051    o cleaned up the use of rhoNil and rhoConst.
2052      - rhoNil should only appear in the LINEAR equation of state, everywhere
2053        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2054        and the dynamical equations are all divided by rhoConst
2055    o introduced new parameter rhoConstFresh, a reference density of fresh
2056      water, to remove the fresh water flux's dependence on rhoNil. The default
2057      value is 999.8 kg/m^3
2058    o cleanup up external_forcing.F and external_forcing_surf.F
2059      - can now be used by both OCEANIC and OCEANICP
2060    checkpoint46h_pre
2061    
2062     Added code to convert surface volume flux (fresh water) into
2063     a mass flux when using P coordinates in the ocean (OCEANICP).
2064     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2065    
2066    checkpoint46g_post
2067    o Include a new diagnostic variable phiHydLow for the ocean model
2068      - in z-coordinates, it is the bottom pressure anomaly
2069      - in p-coordinates, it is the sea surface elevation
2070      - in both cases, these variable have global drift, reflecting the mass
2071        drift in z-coordinates and the volume drift in p-coordinates
2072      - included time averaging for phiHydLow, be aware of the drift!
2073    o depth-dependent computation of Bo_surf for pressure coordinates
2074      in the ocean (buoyancyRelation='OCEANICP')
2075      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2076        Theta, Salinity, and Pressure in the parameter list. This routine is
2077        presently contained in find_rho.F. This routine does not give the
2078        correct density for 'POLY3', which would be a z-dependent reference
2079        density.
2080    o cleaned up find_rho
2081      - removed obsolete 'eqn' from the parameter list.
2082    o added two new verification experiments: gop and goz
2083      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2084    checkpoint46g_pre
2085    
2086    checkpoint46f_post
2087    o Enable tangent linear (forward mode) gradient checks:
2088      - extended active file handling to g_... files
2089      - added TANGENT_SIMULATION to theSimulationMode
2090      - extended grdchk package accordingly
2091    o added tangent linear setup in verification/carbon/code_ftl
2092    o added adjoint setup in verification/front_relax/code_ad
2093    
2094    checkpoint46e_post
2095    o Added new equation of state -> MDJWF
2096      - EOS of McDougall et al., 2002, JAOT, submitted
2097      - caveat: the equation of state is only valid for a smaller (more
2098        realistic?) range of values than JMD95P/Z and UNESCO
2099      - added masks to the calculation of pressure in store_pressure
2100      - added more check values for density in check_eos (ini_eos.F), some of
2101        the old check values are out of the range of the MDJWF-eos, so don't
2102        expect perfect matches for those
2103    checkpoint46e_pre
2104    
2105    checkpoint46d_post
2106    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2107      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2108      case of pressure coordinates. eosType='JMD95Z' in
2109      combination with buoyancyRelation='OCEANICP' now causes an error.
2110    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2111      in find_alpha/beta.
2112    checkpoint46d_pre
2113    
2114    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2115      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2116    
2117    checkpoint46c_post
2118    o Changes necessary for ocean in p-coordinates
2119     -  Added new buoyancy relation = 'OCEANICP'
2120     -  Added new parameters = gravitySign (this used to be contained inside
2121        the factor dRdZ which I added when we first switched to R coordinates).
2122     X GM/Redi is not compatible (yet)
2123     X bottom drag and no-slip need to be debugged.
2124    checkpoint46c_pre
2125    
2126    checkpoint46b_post
2127    o Added new equation of state -> JMD95Z and JMD95P
2128      - EOS of Jackett and McDougall, 1995, JAOT
2129      - moved all EOS parameters into EOS.h
2130      - new routines ini_eos.F, store_pressure.F
2131    o Added UNESCO EOS, but not recommended because it requires
2132      in-situ temperature (see JMD95)
2133    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2134      unesco.f to be used with POLY3
2135    checkpoint46b_pre
2136    
2137    checkpoint46a_post
2138    o Added (atmospheric) pressure loading
2139      - new field in FFIELDS.h, etc...
2140      - new cpp flag ATMOSPHERIC_LOADING
2141    o Changed hFacC to _hFacC in calc_phi_hyd.F
2142    o Added SHORTWAVE_HEATING to some files for consistency
2143    checkpoint46a_pre
2144    
2145    checkpoint46
2146    further merges from release1_p5
2147    o new ctrl package
2148      - adopted from ECCO environment to enable optimization
2149      - added Eliassen Palm fluxes to controls
2150    o added Eliassen Palm flux controls to gradient check package
2151    o cost package
2152      - Compatible with new ctrl package
2153      - added Eliassen Palm cost hooks
2154      - modif's of existing cost functions
2155    o Adjoint-related bug fixes in kpp:
2156      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2157      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2158    o autodiff package
2159      - flow directives:
2160        + new for S/R do_the_model_io
2161        + enhanced for S/R checkpoint
2162        + new gmredi.flow
2163      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2164        disable adcommon.h/g_common.h by default.
2165      - fixed problem for adjoint of global_max
2166    o modified verification/carbon/
2167    o New setup for adjoint of global_ocean
2168    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2169    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2170    o incorporated hooks for sponge layer code (external_forcing.F)
2171    
2172    checkpoint45d_post
2173    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2174    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2175      (affects plume_on_slope "cg2d" output)
2176    o add new parameter deltaTfreesurf for free-surface time stepping
2177    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2178    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2179    o change phiMin in exp1 (to agree with documentation)
2180    o add new flags:
2181     - T,S forcing inside/outside Adams-Bashforth
2182     - turn off temp,salt advection and/or forcing
2183     - for each tracer, define internal flag for multiDimAdvection & A-B
2184    o monitor: change definition of KE to check conservation of Energy
2185    
2186    checkpoint45c_post
2187    o Removed f90 comments ("!")
2188    o Modified initialisations to enable exf package for MITgcm
2189      (without invoking ECCO_PACKAGE).
2190    o modifications to gradient check package (Martin Losch)
2191      - enable centered differences
2192      - modified format of standard output
2193    
2194    checkpoint45b_post
2195    o cleaned exchange calls in cg2d
2196    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2197    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2198      to configure barotropic setup (Martin Losch)
2199    o moved some initialisations within bi,bj loop in dynamics
2200      (TAF flow dependency)
2201    o in initialise_varia, moved call packages_init_variables
2202      before convective_adjustment_init
2203      (corresponding adjustment of TAF tape initialisation).
2204    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2205    
2206    checkpoint45a_post
2207    o compute Rho over the whole domain (extend iMin,jMin indices)
2208    o specific exchange for X-slice domain (case Ny=1)
2209    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2210    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2211    
2212    checkpoint44h_post = checkpoint45
2213    o Fix to restore differentiability:
2214      place at which packages_init_variables is called in
2215      initialise_varia is crucial for reverse control flow.
2216    o modifications in GMRedi to enable stable adjoint
2217      (corresponding modif's in thermodynamics, dynamics)
2218    o added missing hook for sponge layer code in external_forcing
2219    o modified test cost functions
2220    o storing in gad_advection (plus removal of write(0,*)!
2221    o missing headers TR1.h added in convective_adjustment routines
2222    o errorMessageUnit set non-equal zero in eeboot
2223      (conflict on some platforms, e.g. IBM SP3)
2224    o modified carbon verif.
2225    
2226    checkpoint44h_pre
2227    o vertical grid option: allow to put the Interface at the middle between
2228      2 cell-centers ; replace delZ in pkg/kpp by drF.
2229    o GM Advective form: Tracers are advected using the residual transport (=
2230      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2231    
2232    checkpoint44g_post
2233    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2234      results) ; ifdef missing in thermodynamics.F
2235    
2236    checkpoint44f_pre,checkpoint44f_post
2237    o added PTRACERS package
2238      This allows an arbitrary number of passive tracers to be integrated
2239      forward simultaneously with the dynamicaly model.
2240      + Implemented so far:
2241        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2242        - I/O and checkpointing
2243        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2244      + Not implemented so far:
2245        - KPP
2246        - OBCS
2247      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2248        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2249        line in data.pkg.
2250      + This package is disabled by default since it increases storage.
2251    
2252    
2253    o testscript: added -cleanup option
2254    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2255                 b) enable to filter 2D fields.
2256    
2257    checkpoint44e_pre,post
2258    o re-wrote convective adjustment to use pre-calculated weights
2259      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2260      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2261      Original calls to convect() still in place.
2262    
2263    chkpt44d_pre,post
2264    o added missing EXCLUDE_MONITOR flags
2265    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2266      (incompatible typ in MIN/MAX expressions caused problems
2267      on IBM SP3)
2268    o in genmake added variable MAKEDEPEND
2269      plus resetting for case SunOS
2270    o added timer_stats.c routine for IBM SP3
2271    o removed variables in dynamics
2272    !!! I forgot to create tag chkpt44d_pre !!!
2273    !!! But chkpt44d_pre = chkpt44c_post    !!!
2274    
2275  o real fresh water flux implemented with non-linear free-surface.  o real fresh water flux implemented with non-linear free-surface.
