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

1173    checkpoint52e_pre
1174    
1175    o fix bug in impldiff when Nr=1 or Nr=2.
1176    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1177    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1178    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1179      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1180    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1181    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1182    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations

1193      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1194      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1195        of surface winds for the cube
1196      (A verification experiment, based on global_ocean.cs32x15, but with
1197       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1198       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1199       complete with example surface forcing files and matlab scripts to look
1200       at the output and compare it with that of global_ocean.cs32x15.)
1201    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1202       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1203       to conform to the common rule.
1204    o check-in the first version of the coupler + interfaces for multi-components
1205       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1206       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1207       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1208       - ocean and atmos. share the same horizontal grid (no interpolation).
1209       - exchanges between component and coupler is done in forward_step
1210    o new verification experiment, cpl_aim+ocn:
1211       coupled ocean - AIM atmosphere on cs32 grid.
1212    
1213    checkpoint52d_pre
1214    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1215    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1216    
1217    checkpoint52c_post
1218    o Fixing OPTIONS files for use of exf:
1219      - ALLOW_ECCO not needed
1220      - ECCO_CPPOPTIONS.h should not be included from
1221        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1222        as has been the case in the past
1223      - All cal/exf related options are currently set in
1224        single header file. Should remain so until we
1225        agree on a consistent new policy.
1226    o Removed all CPP options for cal package.
1227      cal has no more CPP options.
1228    o modified STOREs in GAD_ADVECTION
1229    o corrected key comp. for passkey
1230    
1231    checkpoint52b_post
1232    o new version: "thsice" of thermodynamic sea-ice pkg:
1233     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1234     - modify fluxes but do not change theta directly;
1235     - light cleaning of bulk_force pkg (still needed with thsice).
1236     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1237       + output_thsice.txt to test thsice & bulk_force pkgs.
1238    o put back grid & coriolis monitor output.
1239    checkpoint52b_pre
1240    
1241    o call "do_the_model_io" at the beginning (=> dump initial state)

1243    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1244      (need info on NUMBER_OF_PTRACERS)
1245    o missing PTRACERS headers in some routines
1246    o default tamc.h in pkg/autodiff supposed to crash
1247      to ensure proper customization
1248    
1249    checkpoint52a_post
1250    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1251      - moved surfaceTendencyTice from pkg/seaice to main code
1252      - subroutine FREEZE_SURFACE now limits only surface temperature
1253        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1254        => new output.txt for global_ocean.cs32x15 & global_with_exf
1255      - keep the old version of FREEZE for backward compatibility;
1256        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1257      - corresponding modifs for TAF directives
1258    o added surface flux output variables to TIMEAVE_STATVARS

1264    checkpoint52a_pre
1265    o some bug fixes for #undef REAL4_IS_SLOW
1266    
1267    checkpoint52 = ecco_c52_e35
1268    o after testing adjoints of checkpoint51u_post
1269    
1270    checkpoint51u_post
1271    o this is the post-merge tag of the ecco-branch
1272      (needs another clean checkout and re-testing)
1273    o various natl_box_adjoint configs and results
1274      but no input fields
1275    o obcs adjoint not yet merged!

1282      (new namelist ecco_cost_nml)
1283    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1284    
1285    checkpoint51t_post
1286    o this is the pre-merge tag of the ecco-branch
1287    
1288    checkpoint51s_post
1289    o cleanup: removed various obsolete #define-s
1290    o pkg/grdchk
1291      - renamed 'ph-grd 3' to 'grad-res'
1292      - merged from ecco-branch
1293        (remaining bug fixes for obcs gradient checks)
1294      - additional high-precision output for testreport
1295        (grep for 'precision_grdchk_result')
1296    
1297    checkpoint51r_post
1298    o cleaned up or removed CPP_OPTIONS.h files
1299    o updated results for some of the tests to reflect the new
1300      optfiles (-ieee: -O0 instead of -O3)
1301    
1302    checkpoint51q_post
1303    o cd_code:
1304      - moved cd_scheme.F -> cd_code_scheme.F
1305      - separate read_checkpoint from cd_code_ini_vars.F
1306      - separated cd_code part from write_checkpoint

1316    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1317    
1318    checkpoint51p_post
1319    o create initial cd_code package
1320      - WARNING: the initialization of fields within packages
1321        is broken because INI_FIELDS (where READ_CHECKPOINT is
1322        called) is called *before* PACKAGES_INIT_VARIABLES.
1323        This seems to be backwards since
1324        1) its important to initially zero the entire field including
1325           the "halo" region
1326        2) zeroing needs to be done *before* reading pickup info
1327           and the pickup call might or might not happen in any
1328           particular run
1329      - this needs an overhaul for R2
1330    o cleanup verification/*/code/GMREDI_OPTIONS.h

1364      - moved surfaceTendencyTice from pkg/seaice to main code
1365      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1366      - subroutine FREEZE now limits only surface temperature
1367        (this means new output.txt for global_ocean.90x40x15,
1368         global_ocean.cs32x15, and global_with_exf)
1369    o added surface flux output variables to TIMEAVE_STATVARS

1518      - new subroutine in ptracers
1519    o modify code for biogeo packages
1520      - in model/src and pkg/ptracers
1521    
1522    checkpoint51
1523    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1524      - autodiff, ctrl, exf, grdchk, seaice
1525      kept separate packages
1526      - cost, ecco, obcs
1527    o updating verification/internal_wave, verification/lab_sea
1528      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1529    
1530    checkpoint50i_post
1531    o Preparing next differentiable checkpoint and sync
1532      of MAIN vs. ecco-branch
1533      - 1st step: this one is differentiable
1534      - 2nd step: next(! not this) checkpoint will have updated packages
1535                  from ecco-branch)
1536    
1537    checkpoint50h_post
1538    o new package "land": provide surface BC for AIM.
1539    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1540    o AIM: use true log-P extrapolation for near surface temp (= as in
1541        F.Molteni paper) ; update aim.5l_cs output.
1542    o New variable in PARM03 for more flexible pickups
1543    o somewhat cleaned package initialisation sequence for
1544      ctrl/ cost/ ecco/ in packages_... routines
1545    
1546    checkpoint50g_post
1547    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1548      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1549      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1550        made the default because of faster convergence than ADI
1551    
1552    checkpoint50f_post
1553    o exf totally restructured
1554      - replaced all exf_set_ routines by one generic exf_set_gen.F
1555        and made sure it's still differentiable
1556      - split exf_getffields.F into new exf_bulkformulae.F
1557      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1558      - updated adjoint/makefile and relevant verif. accordingly
1559    
1560    checkpoint50f_pre
1561     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1562          + change Evap over land. (update aim.5l_cs output)
1563     o added missing .cvsignores and made uniform across expts
1564     o changed configuration of tidal_basin_2d expt
1565     o added pkg/debug functions for tracing code in fatal crashes
1566     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1567     o new fn in pkg/monitor to stop model if solution grows too big
1568     o removed lots of single quotes from comments
1569    
1570    checkpoint50e_post
1571    o make KPP work with PTRACERS
1572     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1573       nearly a copy of kpp_transport_s
1574     - there is no analogue to SurfaceTendencyS, so I have to use
1575       gPtr(of the surface layer) instead
1576    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1577    checkpoint50e_pre
1578    
1579    checkpoint50d_post
1580    o change kpp output from multiple-record state files to single-record state
1581      files analogous to write_state.F
1582    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1583      analogous to the cg2d-related output.
1584    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1585      so that writing to internal file fn (with length 512) fails.
1586    checkpoint50d_pre
1587    
1588    checkpoint50c_post
1589    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1590    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1591    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1592    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1593    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1594    
1595    checkpoint50c_pre
1596    Merging from release1_p13:
1597    o bug fix for pkg/seaice dynamic solver
1598    o Added SEAICE_initialHEFF to pkg/seaice
1599    
1600    checkpoint50b_post
1601    o store u*,v* in gU,V instead of in guNm1,gvNm1
1602    o in order to put the momForcing out of the Adams-Bashforth:
1603      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1604      to timestep.F
1605    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1606    o re-generate output for highly sensitive test-exp:
1607       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1608    
1609    checkpoint50b_pre
1610    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1611    o corrected CPP option mismatch in exf_Bulk... functions for case
1612      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1613    
1614    checkpoint50a_post
1615    o Bug fix for merging between c50 and KPP.
1616      ikey was passed from thermodynamics to kpp_calc via
1617      common block rather than being recomputed in kpp_calc,
1618      in contradiction with new key itdkey.
1619      New key ikppkey created, and tamc.h headers updated.
1620    
1621    checkpoint50
1622    - 2nd step of merge with ecco-branch:
1623      merge changes in ecco-branch back into main trunk
1624    - bug fix in find_alpha
1625    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1626    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1627    - merged some sliced AD support routines
1628    
1629    checkpoint49
1630    merged from ecco-branch:
1631    o exf:
1632      - Enable initialisation of forcing fields to constant
1633        (runtime) values.
1634      - in exf_getffields.F
1635        Reduce i-/j-loop to interior domain, discarding overlaps.
1636        That also fixes wrong TAF-key computations for key_1, key_2
1637        with bulf formulae.
1638      - exf_init.F modify #ifdef for exf_init_evap
1639      - exf_getffieldrec.F, ctrl_getrec.F
1640        The following INT-usages are not safe:
1641          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1642          fldcount = int(fldsecs/fldperiod) + 1
1643        and were modified.
1644    o autodiff: checkpoint_lev...
1645      - updated storing for bulk formulae (some arrays were missing)
1646      - added state for seaice package
1647      - synchronized with main branch
1648    o DIVA:
1649      Modif.s in
1650      - the_main_loop.F
1651      - the_model_main.F
1652      and added cost_final_restore.F cost_final_store.F
1653      o With these changes, it is possible to fully separate
1654        the first forward run to compute the cost function (mdthe_main_loop)
1655        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1656        into separate model executions.
1657        This enables better tuning of DIVA to given queue sizes.
1658      o Loss of cost function value in consecutive DIVA runs is
1659        fixed by storing to 'costfinal' file.
1660      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1661        beginning/end of adjoint integration is accounted for.
1662      The current changes apply to TAF-1.4.26.
1663      TAF has one remaining bug, requiring one manual change
1664      (see MITgcm manual).
1665    o cal: synchronized between MAIN and ecco-branch
1666    
1667    checkpoint48i_post
1668    o Changes to restore differentiability of code w.r.t. previous tag
1669      (mostly adding new routines to make list and replacing
1670      pressure by totPhiHyd).
1671    o Updated and merged grdchk package
1672      - has both ADM and TLM checks
1673      - works for single- and multi-proc.
1674      - output cleaned
1675      - worked successfully for parallel DIVA
1676    o genmake:
1677      - Adding -platform=SP4
1678      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1679    o Modif. for DIVA:
1680      ctrl_unpack should not be called in intermediate DIVA interval.
1681      (similar thing would apply for active files such as
1682      tbar, sbar, psbar, which should not be reinitialised;
1683      only relevant for ecco-branch)
1684    
1685    checkpoint48h_post
1686    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1687    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1688    o Added SEAICE_initialHEFF to pkg/seaice
1689    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1690    
1691    checkpoint48g_post
1692    --- EOS:
1693    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1694      store total Potential in totPhyHyd for diagnostics & EOS.
1695    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1696    --- Pressure/geopotential gradient:
1697    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1698    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1699      ( changes results of global_ocean_pressure )
1700    o NLFS + z-coord.: add eta*Rho' contribution.
1701    o accurate phiHyd when using interface-W at the middle between 2 centers
1702     ( changes results of ideal_2D_oce )
1703    o includes r* 2nd term in potential gradient.
1704    
1705    checkpoint48f_post
1706    Merging from release1_p12:
1707    o Modifications for using pkg/exf with pkg/seaice
1708      - improved description of the various forcing configurations
1709      - added basic radiation bulk formulae to pkg/exf
1710      - units/sign fix for evap computation in exf_getffields.F
1711      - updated verification/global_with_exf/results/output.txt
1712    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1713      (SBO) core products, including oceanic mass, center-of-mass,
1714      angular, and bottom pressure (see pkg/sbo/README.sbo).
1715    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1716      to avoid negative values in shallow regions.
1717      - updated verification/natl_box/results/output.txt
1718      - updated verification/lab_sea/results/output.txt
1719    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1720    o Added useSingleCpuIO option (see PARAMS.h).
1721    o Updated useSingleCpuIO option in mdsio_writefield.F to
1722      work with multi-field files, e.g., for single-file pickup.
1723    o pkg/seaice:
1724      - bug fix in growth.F: QNET for no shortwave case
1725      - added HeffFile for specifying initial sea-ice thickness
1726      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1727    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1728      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1729    o pkg/seaice:
1730      - adjoint-friendly modifications
1731      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1732    
1733    checkpoint48e_post
1734    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1735    o dynamics: change definition of computational domain & adapt mom_fluxform
1736      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1737    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1738        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1739        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1740        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1741        inverted_barometer solid-body.cs-32x32x1
1742      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1743    
1744    checkpoint48d_post
1745    o in preparation for r*:
1746     a) use pre-computed gradient of hydrostatic potential:
1747        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1748     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1749        => affects results of glob_oce_pressure (different truncation error)  
1750      update output.txt of ideal_2D_oce & global_ocean_pressure
1751    
1752    checkpoint48d_pre
1753    o in preparation for r*:
1754      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1755      pass the 2 comp. of the grad. as arguments to momentum S/R.
1756      but for the moment, only used if it does not change the results.
1757    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1758    
1759    checkpoint48c_post
1760    Modifications in treatment of initial flux forcing controls
1761    to avoid extra storing of flux fields.
1762    
1763    checkpoint48c_pre
1764    o Added tidal_basin_2d experiment (currently 1D!)
1765    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1766    
1767    checkpoint48b_post
1768    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1769     (modification to pressure gradient not yet implemented)
1770    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1771      (for U & V) that are used for vertical advection of momentum.
1772    
1773    checkpoint48a_post
1774    o In preparation for r*, use temp. array to compute vertical transport
1775       in flux-form momentum pkg. => change results of few test-exp.
1776      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1777                        lab_sea, natl_box & plume_on_slope
1778    
1779    checkpoint48
1780    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1781    
1782    checkpoint47j_post
1783    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1784    o moved adexch from forward_step to addummy_in_stepping
1785    o added exch in ctrl_map_...
1786    o aveFreq.=0. at end of cost_final to avoid overwrite in
1787      reverse checkpointing loop
1788    o Yet more changes in gmredi:
1789      * adgmredi_calc_tensor
1790        avoiding all recomputation of gmredi_slope_limit
1791      * adgmredi_x/y/rtransport
1792        added flag for excessive storing to avoid recomp. of
1793        u/v/rtans, dTdx/y/z
1794        -> this is not really necessary and very memory-consuming
1795      * adgmredi_slope_psi:
1796        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1797      * gmredi_slope_limit
1798        re-activated full calculation of taperfct for case 'ac02'
1799    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1800    
1801    checkpoint47i_post
1802    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1803    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1804      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1805    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1806    o gmredi: fix few bugs.
1807    
1808    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1809    This will be a good checkpoint to plug into the ecco-branch.
1810    o few modif.'s to get latest version adjointed
1811      (mainly kick out code in ini_linear_phisurf)
1812    o modif's to run adjoint with exactConserv
1813    o case GM_BOLUS_ADVEC should be cleaned
1814      S/R gmredi_slope_psi should be cleaned
1815    o verification/carbon now has exactConserv=.TRUE.
1816    
1817    checkpoint47g_post
1818    o time-average AIM output: becomes independent from statvars time-average
1819      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1820    o After TAF bug fix:
1821      Tested adjoint of gmredi package.
1822      Tests were done with checkpoint47 rather than with latest
1823      checkpoint47f_post since the latter is broken for the adjoint
1824      verification/carbon/ contains both ADM and TLM gradient checks.
1825    Here they are, before they get changed/lost/stolen.
1826    Mostly modif.'s to fix numerical sensitivities.
1827    Gradient checks OK for
1828    - GM_taper_scheme:
1829      * clipping
1830      * ac02
1831      * linear
1832      * glw91
1833      * dm95
1834      * ldd97
1835    - GMREDI_OPTIONS:
1836      * GM_VISBECK_VARIABLE_K
1837      * GM_NON_UNITY_DIAGONAL
1838      * GM_EXTRA_DIAGONAL
1839      * GM_BOLUS_ADVEC
1840    in conjunction with data.gmredi parameters to be checked in
1841    in a few minutes under verification/carbon/code/
1842    
1843    checkpoint47f_post
1844    Merging from release1_p10:
1845    o modifications for using pkg/exf with pkg/seaice
1846      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1847        and SEAICE_EXTERNAL_FLUXES
1848      - pkg/exf CPP options EXF_READ_EVAP and
1849        EXF_NO_BULK_COMPUTATIONS
1850      - usage examples are Experiments 8 and 9 in
1851        verification/lab_sea/README
1852      - verification/lab_sea default experiment now uses
1853        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1854    
1855    checkpoint47e_post
1856    o created a tag prior to creating a branch
1857    
1858    checkpoint47d_post
1859    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1860      at the bottom boundary had an erroneous half slip boundary condition
1861    o added bottom drag and no slip boundary condition capabilities to
1862      oceanic pressure coordinates code
1863    o added new verification experiment global_ocean_pressure, this experiment is
1864      also described in the tutorial section of the manual
1865    checkpoint47d_pre
1866    
1867    checkpoint47c_post
1868    o Added a verification experiment for a global cubed-sphere ocean run
1869      -  verification/global_ocean.cubed32x32x30
1870      -  uses pkg/therm_seaice and pkg/bulk_forcing
1871    
1872    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1873    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1874      when using P-coordinate; only implemented for atmospheric config.
1875    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1876      NOTES: requires option NONLIN_FRSURF to be "#define".
1877    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1878    
1879    checkpoint47b_post
1880    Merging from release1_p9:
1881    o pkg/seaice
1882      - removed GOTO's and added taf directives
1883      - double precision constants to reduce the g77 (Linux)
1884        to F77 (SGI) differences reported in release1_p8
1885    o tools/genmake
1886      - added SGI options

1888      - updated to that of checkpoint47a_post
1889    o verification/global_ocean.90x40x15/input/eedata
1890      - modified for SGI f77 compatibility
1891    o verification/lab_sea
1892      - added description of sea-ice model
1893      - added missing matlab routines
1894      - added test of thermodynamics parallelization
1895    
1896    checkpoint47a_post
1897    o new pkg: aim_v23
1898     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1899       for now, keep the same surface forcing as before.
1900     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1901     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1902     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1903    o add diagnostic of surface correction term in monitor output
1904    
1905    o bulk_force and therm_seaice
1906    - Two packages:  bulk_force (Bulk forcing)
1907      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1908    - Earlier integration from Stephaine Dutkiewicz
1909      and Patrick Heimbach.
1910    - Two ifdef statements for compile time,
1911       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1912    
1913    checkpoint47
1914    differentiable version of checkpoint46n_post
1915    o bug fix in quasihydrostaticterms
1916    o * "clean" adjoint code (in terms of extensive recomputations)
1917        can now be obtained for all GMREDI options (i.e. for
1918        - GM_VISBECK_VARIABLE_K
1919        - GM_NON_UNITY_DIAGONAL
1920        - GM_EXTRA_DIAGONAL
1921        - GM_BOLUS_ADVEC )
1922      * However, wrong gradient check problem remains unsolved.
1923      * New CPP options have been introduced for different
1924        tapering schemes
1925    o external_fields_load now part of differentiation list
1926    o pressure needs multiple storing;
1927      would be nice to have store_pressure at beginning or
1928      end of forward_step, e.g. by having phiHyd global (5-dim.)
1929      (NB: pressure is needed for certain cases in find_rho,
1930      which is also invoked through convective_adjustment).
1931    o recomputations in find_rho for cases
1932     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1933    o #define ATMOSPHERIC_LOADING should be differentiable
1934    o ini_forcing shifted to begining of initialise_varia
1935    o Incorporating QNVS line search routines into MITgcm
1936      (this is separate code, and therefore not under pkg)
1937      lsopt/, optim/
1938    o Updated verification/carbon/
1939      - #define GM_VISBECK_VARIABLE_K
1940      - GM_taper_scheme    = 'ldd97'    
1941    
1942    checkpoint46n_post
1943    Merging from release1_p8:
1944    o verification/natl_box:
1945      updating new external_fields_load routine
1946    o New package: pkg/seaice
1947      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1948      The sea-ice code is based on Hibler (1979-1980).
1949      Two sea-ice dynamic solvers, ADI and LSR, are included.
1950      In addition to computing prognostic sea-ice variables and diagnosing
1951      the forcing/external data fields that drive the ocean model,
1952      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1953      The implied surface heat flux is then stored in variable
1954      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1955      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1956      non-local transport term.  Because this call precedes model
1957      thermodynamics, temperature under sea-ice may not be "exactly" at
1958      the freezing point by the time theta is dumped or time-averaged.
1959      N.B.: fairly large differences in accuracy occur across
1960            different platforms/compilers; comparison between
1961            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1962            generated output gives:
1963       T           S           U           V

1969      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1970    o GAD:
1971      - generated new common blocks to account for call of
1972        same gad routines with differing traceridentities
1973        (needed to modify tracerIdentity indices in GAD.h)
1974      - generated separate common blocks for case useCubedSphereExchange
1975        (Department of Futurology)
1976      - parameter lists to gmredi_?transport: added tracerIdentity
1977      - added new key indices to tamc.h
1978    o external_fields_load:
1979      - added this routine to TAF list
1980      - needed to make some common blocks global and additional storing
1981        along the same lines as exf package (checkpoint_lev?_directives.h)
1982    o exf:
1983      updated external forcing package
1984      - bug fixes carried over from ecco-branch
1985        (missing OBCS_OPTIONS.h in two routines)
1986      - enable easy to use "no forcing".
1987      - added exf I/O for atmospheric loading
1988      - added exf I/O for runoff data
1989      - transfered scaling between exf <-> MITgcm to exf namelist
1990    o Adding new verification experiment global_with_exf.
1991      This verification experiment is almost identical to the
1992      global_ocean.90x40x15 experiment, except that it uses
1993      the exf (and cal) package instead of the
1994      external_fields_load routine (cf README file).
1995    
1996    checkpoint46m_post
1997    o modified testscript to return -- when there are no lines of "%MON" output
1998    o added new flag "quasiHydrostatic" for QH mode
1999      and new routine quasihydrostaticterms()
2000    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2001      New routine: mom_u_coriolis_nh()
2002    o fixed sign of non-hydrostatic metric terms in u and v equations.
2003      Depend on correct sign of gravitySign.
2004  o added work.pc* to .cvsignore in aim directories using ifc  o added work.pc* to .cvsignore in aim directories using ifc
2005  o introduced flag for controllin non-hydrostatic metric terms  o introduced flag for controllin non-hydrostatic metric terms
2006  o removed gravitySign from PARM04  o removed gravitySign from PARM04
