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

1133    o added useSingleCPUIO flag to monitor.F and mon_out.F
1134    o added temporary hack for sea-ice dynamics on the cube:
1135      metric terms are ignored and it is assumed that
1136      there is no sea-ice on cube faces 1, 2, 4, and 5.
1137    
1138    checkpoint52f_post

1146      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1147    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1148      to work with implicit vertical advection and AB ;
1149    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1150    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1151     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1152    checkpoint52e_pre
1153    
1154    o fix bug in impldiff when Nr=1 or Nr=2.
1155    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1156    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1157    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1158      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1159    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1160    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1161    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1162

1165      - updated output accordingly
1166      - changed hs94.128x64x5 to use intial T from file rather than use the
1167        random number generator
1168    o add infrastructure in model routines for fizhi and gridalt packages
1169    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.

1172      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1173      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1174        of surface winds for the cube
1175      (A verification experiment, based on global_ocean.cs32x15, but with
1176       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1177       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1178       complete with example surface forcing files and matlab scripts to look
1179       at the output and compare it with that of global_ocean.cs32x15.)
1180    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1181       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1182       to conform to the common rule.
1183    o check-in the first version of the coupler + interfaces for multi-components
1184       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1185       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1186       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1187       - ocean and atmos. share the same horizontal grid (no interpolation).
1188       - exchanges between component and coupler is done in forward_step
1189    o new verification experiment, cpl_aim+ocn:
1190       coupled ocean - AIM atmosphere on cs32 grid.
1191    
1192    checkpoint52d_pre
1193    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1194    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1195    
1196    checkpoint52c_post
1197    o Fixing OPTIONS files for use of exf:
1198      - ALLOW_ECCO not needed
1199      - ECCO_CPPOPTIONS.h should not be included from
1200        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1201        as has been the case in the past
1202      - All cal/exf related options are currently set in
1203        single header file. Should remain so until we
1204        agree on a consistent new policy.
1205    o Removed all CPP options for cal package.
1206      cal has no more CPP options.
1207    o modified STOREs in GAD_ADVECTION
1208    o corrected key comp. for passkey
1209    
1210    checkpoint52b_post
1211    o new version: "thsice" of thermodynamic sea-ice pkg:
1212     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1213     - modify fluxes but do not change theta directly;
1214     - light cleaning of bulk_force pkg (still needed with thsice).
1215     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1216       + output_thsice.txt to test thsice & bulk_force pkgs.
1217    o put back grid & coriolis monitor output.
1218    checkpoint52b_pre
1219    
1220    o call "do_the_model_io" at the beginning (=> dump initial state)
1221    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1222    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1223      (need info on NUMBER_OF_PTRACERS)
1224    o missing PTRACERS headers in some routines
1225    o default tamc.h in pkg/autodiff supposed to crash
1226      to ensure proper customization
1227    
1228    checkpoint52a_post
1229    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1230      - moved surfaceTendencyTice from pkg/seaice to main code
1231      - subroutine FREEZE_SURFACE now limits only surface temperature
1232        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1233        => new output.txt for global_ocean.cs32x15 & global_with_exf
1234      - keep the old version of FREEZE for backward compatibility;
1235        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1236      - corresponding modifs for TAF directives
1237    o added surface flux output variables to TIMEAVE_STATVARS

1241      but no warning issued by TAF
1242    
1243    checkpoint52a_pre
1244    o some bug fixes for #undef REAL4_IS_SLOW
1245    
1246    checkpoint52 = ecco_c52_e35
1247    o after testing adjoints of checkpoint51u_post
1248    
1249    checkpoint51u_post
1250    o this is the post-merge tag of the ecco-branch
1251      (needs another clean checkout and re-testing)
1252    o various natl_box_adjoint configs and results
1253      but no input fields
1254    o obcs adjoint not yet merged!
1255    o adding ECCO global 1x1 and 2x2 degree configs
1256    o updated/extended some store directives for seaice
1257    o pkg/ecco now containes ecco-specific part of cost function

1261      (new namelist ecco_cost_nml)
1262    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1263    
1264    checkpoint51t_post
1265    o this is the pre-merge tag of the ecco-branch
1266    
1267    checkpoint51s_post
1268    o cleanup: removed various obsolete #define-s
1269    o pkg/grdchk
1270      - renamed 'ph-grd 3' to 'grad-res'
1271      - merged from ecco-branch
1272        (remaining bug fixes for obcs gradient checks)
1273      - additional high-precision output for testreport
1274        (grep for 'precision_grdchk_result')
1275    
1276    checkpoint51r_post
1277    o cleaned up or removed CPP_OPTIONS.h files
1278    o updated results for some of the tests to reflect the new
1279      optfiles (-ieee: -O0 instead of -O3)
1280    
1281    checkpoint51q_post
1282    o cd_code:
1283      - moved cd_scheme.F -> cd_code_scheme.F
1284      - separate read_checkpoint from cd_code_ini_vars.F
1285      - separated cd_code part from write_checkpoint

1295    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1296    
1297    checkpoint51p_post
1298    o create initial cd_code package
1299      - WARNING: the initialization of fields within packages
1300        is broken because INI_FIELDS (where READ_CHECKPOINT is
1301        called) is called *before* PACKAGES_INIT_VARIABLES.
1302        This seems to be backwards since
1303        1) its important to initially zero the entire field including
1304           the "halo" region
1305        2) zeroing needs to be done *before* reading pickup info
1306           and the pickup call might or might not happen in any
1307           particular run
1308      - this needs an overhaul for R2
1309    o cleanup verification/*/code/GMREDI_OPTIONS.h

1344      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1345      - subroutine FREEZE now limits only surface temperature
1346        (this means new output.txt for global_ocean.90x40x15,
1347         global_ocean.cs32x15, and global_with_exf)
1348    o added surface flux output variables to TIMEAVE_STATVARS

1524    
1525    checkpoint50g_post
1526    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1527      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1528      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1529        made the default because of faster convergence than ADI
1530    
1531    checkpoint50f_post
1532    o exf totally restructured
1533      - replaced all exf_set_ routines by one generic exf_set_gen.F
1534        and made sure it's still differentiable
1535      - split exf_getffields.F into new exf_bulkformulae.F
1536      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1537      - updated adjoint/makefile and relevant verif. accordingly
1538    
1539    checkpoint50f_pre
1540     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1541          + change Evap over land. (update aim.5l_cs output)
1542     o added missing .cvsignores and made uniform across expts
1543     o changed configuration of tidal_basin_2d expt
1544     o added pkg/debug functions for tracing code in fatal crashes
1545     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1546     o new fn in pkg/monitor to stop model if solution grows too big
1547     o removed lots of single quotes from comments
1548    
1549    checkpoint50e_post
1550    o make KPP work with PTRACERS
1551     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1552       nearly a copy of kpp_transport_s
1553     - there is no analogue to SurfaceTendencyS, so I have to use
1554       gPtr(of the surface layer) instead
1555    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1556    checkpoint50e_pre
1557    
1558    checkpoint50d_post
1559    o change kpp output from multiple-record state files to single-record state
1560      files analogous to write_state.F
1561    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1562      analogous to the cg2d-related output.
1563    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1564      so that writing to internal file fn (with length 512) fails.
1565    checkpoint50d_pre
1566    
1567    checkpoint50c_post
1568    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1569    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1570    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1571    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1572    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1573    
1574    checkpoint50c_pre
1575    Merging from release1_p13:
1576    o bug fix for pkg/seaice dynamic solver
1577    o Added SEAICE_initialHEFF to pkg/seaice
1578    
1579    checkpoint50b_post
1580    o store u*,v* in gU,V instead of in guNm1,gvNm1
1581    o in order to put the momForcing out of the Adams-Bashforth:
1582      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1583      to timestep.F
1584    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1585    o re-generate output for highly sensitive test-exp:
1586       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1587    
1588    checkpoint50b_pre
1589    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1590    o corrected CPP option mismatch in exf_Bulk... functions for case
1591      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1592    
1593  checkpoint50a_post  checkpoint50a_post
1594  o Bug fix for merging between c50 and KPP.  o Bug fix for merging between c50 and KPP.
