4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/generic_advdiff:
8  o moved ptracer ctrl index 17 -> 32    change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
9      applies to files where Temperature & Salinity 2nd Order moments are used.
10    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
11      this uses a dynamically allocated internal state data structure
12      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
13      and requires a fortran 90 compiler
14    
15    checkpoint59q
16    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
17       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
18    o Refresh tutorial_global_oce_biogeo, notably:
19      - change bathymetry (put back seamounts in ACC, use hFacs)
20      - change EOS (POLY3 --> JMD95Z)
21      - use Bryan-Lewis vertical diffusivity
22      - use multidimensional advection
23      - remove old virtual virtual in dic pkg, now done through ptracer pkg
24      - change a couple of parameters in dic pkg
25    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
26    o pkg/obcs: change default to OBCSfixTopo = .true.,
27      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
28      - replace "debugMode" with "debugLevel .GE. debLevB"
29    o implementation of TAF directives for gchem,cfc,dic
30    o remove "exp5" (replaced by tutorial_deep_convection).
31    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
32      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
33      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
34      --> changes results in exp4, seaice_obcs
35    o tutorial_deep_convection :
36      update the set-up and increase resolution and domain size ; start
37      from pseudo initial conditions = output at t=120mn in order to see
38      something happening when running testreport.
39    o pkg/seaice: add os7mp as an advection scheme
40                  add check for advection schemes
41                  add a flag for restoring T and S underneath sea ice
42    o pkg/my82: add netcdf-support and diagnostics
43    o thsice pkg:
44      - Now hsMax limits snow height by turning it into ice following
45        flooding scheme (and now conserving energy)
46      - Slight rewriting of the formula in thsice_calc_thick.F
47      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
48      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
49    
50    checkpoint59p
51    o gchem / dic / cfc :
52      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
53      - add new parameter files: "data.dic" & "data.cfc" ;
54      - various re-arrangement in initialisation & header file ;
55      - fix tutorial_global_oce_biogeo for multi-threaded test.
56    o pkg/dic: test for "pickup_dic" file when restarting ;
57      if no pickup-file, can restart with a re-initialised pH (same as it did
58      before) providing pickupStrictlyMatch is set to False.
59    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
60      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
61    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
62      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
63    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
64     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
65       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
66    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
67       scheme to use for vorticty-term ;
68     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
69       (with default selectVortScheme, return to original discretisation)
70     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
71    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
72    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
73      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
74      also fix diagnostics VISCAHW & VISCA4W.
75    
76    checkpoint59o
77    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
78    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
79      move a few statemens out the main loop into separate loops
80    o pkg/shelfice:
81      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
82        (kg/m^2/s), does not break tests, because in verification/isomip,
83        rhoConstFresh=rhoConst (by accident)
84      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
85      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
86        new file model/src/seawater.F, so that they are available for all pkgs.
87      - convert potential temperature into in-situ temperature. This changes the
88        isomip tests => update tests
89    o add a flag writePickupAtEnd (default=true) to be able to suppress
90      writing a pickup at the last timestep
91    o tools/mpack-1.6 :
92      - disable automake (not working) and autoconf (not needed).
93      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
94        also cleaner with much less compilation warnings.
95    o pkg/profiles:
96      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
97      (for "less than 32 characters name" compiler requirement)
98    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
99      conditions that have a different sampling frequency than S/T/U/V obcs
100    o pkg/diagnostics (stats-diags):
101      - fix global Min/Max in case 1 processor get only empty tiles
102    o genmake2: replace (4 times)
103         make genmake_tc_1.o >> genmake_warnings 2>&1
104      with
105         COMM="$CC $CFLAGS -c genmake_tc_1.c"
106         echo $COMM >> genmake_warnings
107         $COMM >> genmake_warnings 2>&1
108      to make genmake2 always see the value of CC as specified in the optfile.
109    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
110      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
111      - modify verification advect_cs test to test SOM-advection on CS-grid.
112    o pkg/ctrl:
113      - Rewrite of ctrl_map_ini_ecco.F,
114        introducing a generic routine (ctrl_map_ini_gen.F).
115      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
116    
117    checkpoint59n
118    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
119      number in dedicate array "hdiag":
120      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
121        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
122      - many small changes (integer format) for large number of diagnostics
123      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
124        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
125    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
126      usingSphericalGrid, this allows to define the rotated grid coordinates
127      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
128      geographical coordinates according to the inverse of the rotation defined
129      by the Euler angles, so that Coriolis parameter and online-interpolation by
130      exf works with the geographical coordinates on XC/YC/XG/YG.
131      Naturally, this feature does not work with all packages, so some
132      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
133      profiles), because there the coordinates are assumed to be regular
134      spherical grid coordinates.
135    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
136      - introduce isopycnal diffusion coefficient control.
137    o tools/adjoint_options:
138      - additional control vector components.
139    o pkg/mnc: have mnc create marginally meaning full coordinate variables
140      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
141    o pkg/mypackage:
142      - add example of read/write pickup for state-var ;
143      - add entry points to the main code for state-vars diags & write-pickup.
144    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
145      transitions for useExfYearlyFields
146      - add new subroutine that determines the file to read from for
147        use*YearlyFields = .TRUE. and .FALSE.
148      - add a verification experiment to global_with_exf that tests
149        useExfYearlyFields with USE_EXF_INTERPOLATION defined
150    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
151      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
152      subroutines (which could be generated from a template, because they are
153      almost identical), for now they are included in obcs_prescribe_read.F for
154      simplicity
155    o pkg/exf:
156      - add a little more diagnostic to exf_interp_read (in analogy to
157        mds_read_field, can be turned off with debugLevel < debugLevA=1)
158      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
159        ugly but fast by unrolling short inner loops, inserting a unroll=8
160        directive in routine lagran, and splitting a loop and making do while the
161        outermost loop (the latter requires the intoduction of index arrays)
162    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
163    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
164      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
165    o verification/seaice_obcs: updated for restart test and latest options
166    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
167      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
168      for now this is only available for the C-grid code and also within
169      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
170    
171    checkpoint59m
172    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
173      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
174    o gad_som : fix flux output (& diagnostics) to have same units as other  
175      advection scheme fluxes (was previously multiplied by deltaT).  
176    o added verification/seaice_obcs both to test seaice open boundaries
177      and to provide an example matlab scrpt for generating them
178    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
179    o pkg/salt_plume: clean up salt_plume_frac.F to
180      remove redundancy in PlumeMethod 1 and 4
181    o pkg/kpp: added saltplume diagnostics
182    o pkg/obcs and pkg/seaice:
183      - do not set uice and vice to zero when OB*icefile are unspecified
184      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
185      - moved seaice tracer obcs after call to seaice_growth
186    o pkg/salt_plume: added various options for salt plume depth
187      criterion and for vertical distribution of the salt
188    
189    checkpoint59l
190    o pkg/ptracers: new version of ptracers pickup:
191      read meta file and write only fields which are needed to restart.
192      ( same logic as main pickup file ; also using pickupStrictlyMatch )
193    o pkg/seaice:
194      - add timescale for melting due to warm mixed layer as a means of
195        setting SEAICE_availHeatFrac more conveniently
196      - add a CPP-flag/runtime parameter check for flooding algorithm
197      - reformulated availHeat in seaice_growth.F to be independent of AREA
198    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
199      unit changes
200    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
201    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
202      SX vector computer.
203    o pkg/seaice:
204      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
205        seaice forcing fields can now be read only through pkg/exf
206      - removed some unused halos
207    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
208    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
209      or U/VICE from U/VWIND before computing U/VSTRESS
210    
211    checkpoint59k
212    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
213      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
214    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
215      all experiments pass when compile with un-initialised var. checking option.
216    o added pkg/salt_plume
217    o script to test restart (for now, in MITgcm_contrib/jmc_script)
218    o pkg/seaice: new read/write pickup version.
219      read meta file and write only fields which are needed to restart.
220      ( same logic as main pickup file ; also using pickupStrictlyMatch )
221    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
222    o lab_sea.hb87: modify the domain & update output.hb87.txt :
223      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
224      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
225      process. Fixed here by closing the domain at the Northern boundary.
226    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
227    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
228      a set of consecutive levels in/from a 3-D array.
229    o pkg/ptracers:
230      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
231      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
232    
233    checkpoint59j
234    o in pkgs: dic, obcs, offline, rbcs:
235      standard way to compute coeff. for time interpolation between 2 time reccords
236      which retains full precision (& make results less dependent on compiler).
237      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
238    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
239      packages instead of reading ice cover and wind speed separately
240    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
241     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
242      to allow to compile customized code before the update)
243    o cleaning-up:
244      - fix CPP instruction syntax in pkg/obcs
245      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
246        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
247      - fix some threads issue in IO parts.
248    o pkg/dic:
249      - add tons of "_d 0" (--> much better testreports !)
250       and then update outputs of tutorial_global_oce_biogeo
251    o pkg/mom_fluxform:
252      add a special version of momentum advection intended to conserve momentum
253      next to a bathymetry step or a coastline edge. (default = off = #undef)
254    o new read/write pickup version:
255      - for now, only implemented for main (mdsio) pickup file.
256      - write out only what is needed to restart; merge pickup_nh , pickup_ph
257        and main pickup together.
258      - read meta file; read only what is needed to restart; stop if a field
259        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
260        if it make sense (even if the restart is not perfect).
261      - if no meta file, assume that pickup to read corresponds exactly to
262        a pickup that would currently be written.
263      - read pickup written in the old format (until checkpoint59i) if it
264        recognizes an old meta file (no field-list).
265      - add a meta file in exp. which starts from a pickup: 2 cases:
266        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
267         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
268        b) a meta file describing the content of the associated pickup file
269         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
270    o pkg/mdsio & pkg/rw:
271      - new routine to read a meta file ; new set of routine to read
272        Multiple-fields file (with meta file).
273    o added open boundary conditions capability for seaice
274        HSNOW, HSALT, UICE, and VICE
275    
276    checkpoint59i
277    o adjoint:
278      * fix multiDimAdvection adjoint
279        (partial recomputation problem by TAF for fVerT(:,:,kDown)
280        and comlev1 size definition (maxpass vs. max. number of tracers)
281      * verification/global_ocean.90x45x15 adjoint now tests
282        NLFS and multiDimAdvection using DST3 (=30)
283      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
284    o pkg/kpp: add "_d 0" to real constant (if missing);
285      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
286      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
287    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
288      for internal parameters related to restart process (formerly from PARAMS.h)
289      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
290    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
291      as argument. (only atm2d & obcs write_pickup have not yet been updated)
292    o pkg/monitor:
293      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
294      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
295      - account for deep Atmosphere factor and density factor (anelastic)
296    o added open boundary conditions capability for seaice HEFF and AREA
297    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
298      thermodynamics
299      - requires a little reorganization, which affects the testreport results
300        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
301        so that now the conservative form is tested
302      - add a few comments
303    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
304    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
305    o add new diagnostics to seaice: advective, diffusive fluxes (only for
306      multidim-advection, for scheme 2 they are not filled) and transports,
307      thermodynamic growth rates
308    o change units of EmPmR (inside the code, + within coupling interface)
309      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
310      Affects results @ truncation level (cg2d match) and update output of
311       experiments: lab_sea(6), global_ocean.90x40x15(10),
312      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
313      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
314      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
315      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
316    
317    checkpoint59h
318    o pkg/exf:
319      - improve vectorization by moving if-statement out of loops in
320        exf_mapfields, exf_radiation
321      - exf_bulkformulae.F: introduce 2D fields and vectorize code
322    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
323    o testreport:
324      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
325        monitor & update offline_exf_seaice exp. output.
326      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
327    o pkg/seaice:
328      - bug fix in the evp solver: boundary conditions were affected be
329        masking of zMax/zMin (changes results)
330      - minor bug fix in boundary conditions in seaice_calc_strainrates
331        (changes results for no_slip)
332      - seaice_lsr.F: make interpolation of eta dependent on boundaries
333      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
334      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
335        stress formulation and no-slip boundary conditions
336    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
337      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
338    o pkg/seaice: a first HSALT time stepping equation has been checked in
339    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
340      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
341      without requiring DO-IF statements
342    o pkg/thsice:
343      use continuous power-law function for partition of energy between lateral
344      melting/freezing and thinning/thickening ; old code using step function
345      still available with #undef THSICE_FRACEN_POWERLAW
346      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
347    o testreport: change AD testing : check against results/output_adm.txt
348      using same scripts as for forward test.
349    
350    checkpoint59g
351    o adjoint testing: in preparation for changing testreport:
352      - output format: cost and grad written on separated lines
353      - ad output results in directory "results" (instead of "results_ad")
354    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
355    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
356    o pkg/ecco: allow user defined cost function contributions
357    o testreport:
358      Allow to choose (per experiment) the list of tested output variables
359       and the main variable (used to issue a pass/FAIL ) ;
360      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
361      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
362      Also modify printing of summary:
363       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
364       b) echo the list of tested variables in the individual summary.txt of
365          each experiment.
366    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
367      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
368      (but still depend on the tile decompostion of the domain).
369    o pkg/seaice: change a discretization detail to make the B-grid code
370      "more symmetric". This change is likely to remove all "ridges/leads" that
371      where quasi-aligned with the grid in B-grid solutions. It may also be
372      the solution to the stress coupling issues with the B-grid.
373    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
374      remove .cvsignore from input dir. (since testreport no longer run here).
375    o pkg/thsice:
376     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
377     - fix reshaping of sea-ice just after advection:
378       melt all the ice only if ice-volume is too small.
379     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
380       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
381     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
382    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
383      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
384    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
385      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
386      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
387      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
388      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
389      -> update output.txt
390    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
391     this affects truncation error: -> update output.txt of exp:
392      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
393      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
394    
395    checkpoint59f
396    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
397    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
398      a bounded range (in forward mode)
399    o pkg/ecco, ctrl, autodiff and mom_common:
400     internal parameter controls, completements of implementations
401    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
402    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
403      (not seem any difference in testing results).
404    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
405       at face corners.
406    o pkg/generic_advdiff:
407     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
408      loop range indices for computing vertical advection tendency
409      and do the calculation in the interior only (no overlap) ;
410      for now, only implemented for SOM advection (to save CPU time).
411     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
412    o exch2 adjoint
413      First set of changes:
414      - add exch2 hand-written adjoint templates
415      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
416        This will require cleanup in pkg/autodiff/*.F
417        (changed routines currently kept separate in verif. code/)
418      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
419        that used to hide exch2 or cubed-sphere specific code
420        (commented via 'cph-exch2')
421    o pkg/seaice
422      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
423    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
424       output of global_ocean.cs32x15.thsice .
425    
426    checkpoint59e
427    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
428      for B-grid vector (not yet tested) and C-grid vector (<- only used
429      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
430    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
431      (#ifdef ALLOW_SALT_PLUME)
432    o gather_2d/scatter_2d: removed halo regions
433    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
434      scheme and the corresponding test case (under front_relax dir). For now,
435      only available with Skew-flux form and not yet tested in realistic set-up.
436      adjoint: store directives updated, but gradient checks deteriorated,
437      so maybe GM/Redi adjoint is now broken.
438    o seaice adjoint
439      * add AREA, HEFF, HSNOW as control variable
440        (should not change lab_sea results)
441      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
442    o pkg/seaice:
443      * added computation of saltFlux in seaice_growth;
444        For time being, sea ice salinity is assumed constant
445        contribution of snow flooding to freshening of sea ice is neglected.
446        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
447        defaults to 0.0 in order to maintain backward compatibility.
448        Typical values for SEAICE_salinity are 4 to 10 g/kg.
449      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
450      * added SEAICE_availHeatFrac, which specifies fraction of surface level
451        heat content used to melt or grow ice
452      * commented out cap of HICE: it helps keep ice thinner
453      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
454      * applied OBCS T/S mask to HEFFM sea ice mask
455    
456    checkpoint59d
457    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
458     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
459     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
460    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
461     and change default value of parameter "GM_Small_Number";
462     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
463       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
464       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
465    o pkg/ecco: cost function when applying pkg/smooth to controls
466    o pkg/ctrl: add forcingPrecond run time parameter
467    o pkg/seaice:
468     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
469     - fix bug in metric terms of u-equation in LSR solver (implicit part),
470       changes verification/lab_sea
471     - rearrange implicit part of u-equation in LSR solver to make it easier to
472       read, understand, and debug. This causes changes at the truncation level.
473     - fix (serious) bug in the boundary conditions (sign error in the implicit
474       part) of the LSR solver. Changes all LSR results.
475     - fixed problem with HSNOW initialization to avoid thick snow when AREA
476       is initilized with small values - does not change lab_sea results.
477     - added HsnowFile initialization capability
478    o pkg/smooth: addition to model/src and pkg/ctrl so allow
479     initialization of pkg/smooth and application to control vector
480    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
481    o dependencies: pkg/profiles requires pkg/cal
482    o pkg/profiles:
483     - added option ALLOW_PROFILES_GENERICGRID
484         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
485         that interpolation information (grid points and coefficients) is provided
486         within the netcdf input files.
487         -> sample matlab scripts can be found in MITgcm_contrib/gael
488         that allow you to prepare netcdf input files.
489     - also modified: cleaner include statements, cleaner error print statements,
490       cleaner stops when error, and more tests of the netcdf input files consistency.
491    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
492    o pkg/seaice:
493     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
494       requires a new routine: seaice_diagnostics_fill.F
495     - make sure that seaice does not move if not forced (pressure replacement
496       method, Hibler and Ip, 1995), changes results
497     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
498     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
499       It is turned off by default (=-1.), because it changes the results.
500     - make it possible to read AREA from a file, too.
501    
502    checkpoint59c
503    o add S/R and diagnostics for oceanic mixed-layer depth
504    o move GMRedi call after all vertical mixing schemes (including KPP)
505    o pkg/thsice:
506     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
507      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
508    o pkg/obcs:
509     - bug fix for balance code
510    o pkg/seaice:
511      - allow values of SEAICE_elasticParm > 1
512      - add new parameter SEAICE_evpTauRelax as an alternative
513        to SEAICE_elasticParm
514      - make lsr boundary conditions free slip (by default), changes result
515      - add code for no slip boundary conditions for lsr
516      - set minimum of zeta to zero (and not 4e8) (changes results)
517      - add a cap on AREA after advecting AREA if seaice_growth is not called
518    o change calculation of Visbeck K:
519      - no longer depend on tapering scheme; instead, compute slope (limited
520        by GM_maxSlope). this is equivalent to what was comuted before with
521        clipping or linear tappering.
522      - fix vertical averaging (wrong by 1/2 level)
523      - leave the old version (but will not be maintained) within
524        #ifdef OLD_VISBECK_CALC / #endif
525      - update output of exp. ideal_2D_oce
526    o change error catch in calc_r_star to improve vectorization
527    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
528      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
529    o adjoint:
530      Re-organized adjoint checkpointing according to Matt Mazloff
531      (but with modifs/completions/cleanups)
532      Storing is now bundled into large arrays to optimized I/O
533      (and second step in cleanup of the_main_loop)
534    
535    checkpoint59b
536    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
537      - export/import (between ocean & coupler) fields needed for ocean DIC.
538    o pkg/seaice:
539      - get rid of three more exchanges seaice_calc_viscosities (required
540        different loop boundaries in seaice_lsr and seaice_ocean_stress)
541      - bug fix in seaice_ocean_stress (update of lab_sea required)
542      - reduce loop boundaries to necessary minimum also in seaice_evp
543      - go back to the old way of computing deltaC/Z as the adjoint likes that
544        better
545    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
546      passive tracer to an Age Tracer) + update output.txt
547    o pkg/exf:
548      - implement A-grid / C-grid selection for wind-stress input files.
549      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
550      for now, in exf_bulk_largeyeager04.F only :
551      - change implementation for case where windspeed + 2. components wind-stress
552        are read-in. AND use rhoConstFresh to convert evap.
553    o pkg/seaice:
554      - use correct EXCH_UV for wind-forcing (on A-grid).
555      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
556        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
557    o pkg/exf:
558      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
559      EXF_INTERPOLATION:
560      - merge global_with_exf/code version of exf_interp_read.F
561        to the main code ;
562      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
563        reading the file ; Important: This options needs to be defined to recover
564        previous code.
565        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
566      - no longer loose real*8 precision along the way when using exf_iprec=64.
567    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
568      - change discretisation of evp-solver in order to avoid another exchange
569        (changes lab_sea) and clean up a little
570      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
571        help the adjoint (this also changes the results slightly)
572      - add a few "_d 0" where they had been missing in seaice_evp.F
573      - cleaning up: remove unused seaice_calc_rhs.F
574    o pkg/exf: some cleaning-up:
575      - change various "constants" into runtime parameters
576      - cleaned-up Large&Yeager04 routine which should eventually
577        replace exf_bulkformulae.F (changed names of S/R and CPP)
578        and merged various ALLOW_ATM_WIND options
579     only used with thsice pkg (in thsice_get_exf.F):
580      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
581        which are used when useStabilityFct_overIce=TRUE (= the default)
582      - change default values of ice & snow emissivity and scale downward LW
583        by ice & snow emissivity.
584    o pkg/thsice:
585     fix few little problems, in thsice_calc_thickn.F:
586      - growth vertically (and not laterally) if iceFrac == iceMaskMax
587      - melt only laterally if hIce < hThinIce (as the comments say)
588      and in thsice_extend.F:
589      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
590      - start to form ice as soon as the minimum ice-volume is reachable.
591     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
592      and cpl_aim+ocn
593    o pkg/kpp
594     - move computation of surface related input fields to KPP into a new
595       subroutine kpp_forcing_surf.F
596     - remove wrong (within bi,bj loops) EXCH calls.
597     - little cleaning (add argument myThid in last position, cvs header ...)
598     - for now, fix conservation problem by exchanging KPPviscAz (may not
599       be the best fix)
600    o pkg/seaice
601     - check for inconsistent evp parameter/cpp-flag combination
602     - remove leftover errIO flat for obsolete name list error handling
603    o OpenAD
604     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
605    
606    checkpoint59a
607    o pkg/seaice: some parameter clarifications and a little bit of clean up
608    o pkg/thsice: rename run-time parameters:
609       himin       -> hIceMin
610       himin0      -> hThinIce
611       hihig       -> hThickIce
612       i0          -> i0swFrac
613       transCoef   -> bMeltCoef
614       frac_energy -> fracMelting
615      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
616       with default values (for now) that do not change the results.
617      remove old version of thsice vars advection in pkg/seaice.
618    o in FFIELDS.h:
619      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
620      - make pLoad & sIceLoad always available (but still only used if
621         ATMOSPHERIC_LOADING is #define).
622    o pkg/kpp: replaced _KPP_RL with _RL
623    o bug fixes for vertical diffusivity computations when both KPP and
624        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
625        are no longer updating the vertical diffusivity array
626        (passed as argument) but are (re-) setting those arrays.
627    o pkg/seaice: fix bug in evp solver, while doing that
628      - change (improve?) discretization of stress computations for both
629        cgrid-lsr and evp solver
630      - add a new routine to compute strain rates
631      - the above changes lab_sea results
632      - add no slip conditions for evp solver (off by default), lsr-version
633        may follow
634      - fix exchange for shear at Z-points (does not change lab_sea)
635      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
636        (to force the user to pick a time step since there is not "safe" way
637        of choosing it)
638      - add principal stress diagnostics
639      - rearrange fields for evp a little to avoid having to call a: too many
640        exchanges and b: exchanges for stress trensor components which we do
641        not have.
642      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
643        of evp, complete rewrite for lsr case (latter is does not yet work
644        in all cases)
645    o pkg/kpp: add code to have mixing in shelf ice caverns
646      - add myThid to all kpp routines (long overdue)
647    
648    checkpoint59
649    o pkg/exf:
650      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
651        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
652      - move exf header files from lower_case.h to UPPER_CASE.h ;
653        add missing cvs Header & Name
654      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
655      - add namelist param. selectStressGridPosition, exf_monFreq
656      - retire many _CLIM routines, and remove data.exf_clim
657        + params moved to data.exf
658        + climsst, climsss now handled by exf_set_gen, i.e.
659          climss?period=0 refers to constant field,
660          climss?period=-12 to monthly forcing
661      - split up namelists in data.exf
662    o pkg/seaice:
663      - remove seaice_exch and seaice_exch_uv
664      - remove superfluous exchange of theta
665      - add myThid to seaice_budget_ocean/ice
666      - add new interface for atmospheric wind forcing (C-grid only)
667        + new routine
668        + two new field (taux, tauy for stress over ice)
669        + removed one global field (DAIRN) for C-grid case only
670    o pkg/thsise
671      - 2nd set of modifs for thsice adjoint in conjunction with exf
672    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
673    
674    checkpoint58y_post
675    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
676      vertical diffusivity, similar to that in MOM4; turned on using
677      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
678      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
679    o Added capability for 3D specification of background vertical diffusion
680      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
681      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
682      "data" file that contains the 3D vertical diffusivity coefficients.
683    o ice dynamics (pkg/seaice) with thsice thermodynamics:
684      - add code within pkg thsice to advect & diffuse sea-ice fields
685      similar to (and will replace) what has been added in  seaice_advdiff.F,
686      but: - conserving Mass, Heat & Salt.
687           - better when using non-linear advection scheme (not yet fully tested)
688           - can also be used in atmospheric set-up (for now, only the diffusion).
689    
690    checkpoint58x_post
691    o IO option for global-file compact format:
692      - add options when generating topology (utils/exch2/matlab-topology-generator)
693      - add I/O capability (pkg/mdsio).
694      - adapt utils/matlab/rdmds.m to read this format.
695      for now long-line format not yet supported by pkg/mdsio (& exch2).
696    o shelfice: add a few diagnostics
697    
698    checkpoint58w_post
699    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
700      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
701      (and replace horiVertRatio in NH code).
702      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
703                         and tutorial_plume_on_slope (sensitive to truncation)
704    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
705      directly to drive seaice model (C-grid only)
706    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
707     - reintroduce computation of wind from stress,
708     - compute tau (in exf_bulkformulae.F) from windstress averaged to
709       mass points to avoid tau = 0
710     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
711    o rdmnc.m: make it work with "global" files created with gluemnc
712    o rdmnc.m : some improvements in dealing with singleton dimension
713      (tested on all testreport mnc output files).
714    o genmake2: disable pkg/profiles if netcdf test fails.
715    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
716    o move call to cal_readparms up to make calendar parameters/variable available
717      to all packages
718    
719    checkpoint58v_post
720    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
721      useDynP_inEos_Zc tested.
722    o pkg/exf: changes to properly interpolate/mask/scale initial fields
723    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
724      and portions thereof.  See read_cs.txt for description and examples.
725    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
726      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
727      following the great-circle arc between those 2 points.
728    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
729      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
730    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
731     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
732     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
733     - still needs work (not working with some options ; efficiency to improve)
734       and serious testing.
735     - use this scheme for temperature & salinity in 2 advection test exp.:
736       advect_xy & advect_xz, respectively.
737    
738    checkpoint58u_post
739    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
740    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
741    o testreport: add option "-skipdir" to skip some test.
742    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
743      momentum calculation.
744    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
745    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
746      remove checkpoint.F and the_correction_step.F (no longer used);
747      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
748    o add option (linFSConserveTr) to correct for tracer source/sink due to
749      Linear Free surface
750    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
751    o pkg/thsice: fix reading mnc-pickups
752    
753    checkpoint58t_post
754    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
755    o pkg/mdsio:
756     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
757       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
758       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
759     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
760     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
761       either MDS_READ_FIELD or MDS_WRITE_FIELD )
762     - new S/R (to replace MDSWRITEMETA), which allows to write more
763       informations (variable names, time ...) to meta files.
764     - modify rdmds.m to give back the meta file content.
765    o pkg/diagnostics: change vertical interpolation to be safer, and more
766       flexible (define p-levels to interpolate to in data.diagnostics);
767      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
768       diagnostic pointer.
769    o pkg/seaice: more cleaning up of seaice_growth, added many comments
770    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
771    o fix multi-category seaice:
772     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
773       SEAICE_MULTICATEGORY
774     - fix short wave heat flux
775    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
776       and allow to use EVP solver. Change forward lab_sea: test both EVP
777       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
778    o Initial check-in of lab_sea adjoint
779      (very similar to natl_box_adjoint/code_seaice)
780      * used C-grid and EVP solver
781      * used KPP, GM/Redi
782      * uses inAdExact=.TRUE.
783      * gradient checks fail for both ADM and TLM
784        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
785        f.d. gradients actually seem more problematic than ADM, TLM gradients;
786        issue is related to forward mismatch between g77 an ifort
787    o pkg/seaice: overhaul of thermodynamics
788     - growth.F and groatb.F are replaced by new routine seaice_growth.F
789     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
790     - move a few global fields out of SEAICE.h into seaice_growth.F and
791       make them 2D (FICE/QNETO/ ...)
792     - remove FO (it is the same as QNETO)
793     - introduce a few local fields to avoid modifying external fields such
794       as atemp, etc.
795    
796    checkpoint58s_post
797    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
798      changed exf_set_gen.F so that
799        genperiod=0 means input file is one time-constant field and
800        genperiod=-12 means input file contains 12 monthly means
801    o CG2D: use pre-computed solver main-diagonal (stored in common block);
802      this affects truncation error ; generate new output file for exp. which
803      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
804        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
805        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
806        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
807        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
808        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
809    o start implementation of deep-atmosphere and anelastic formulation
810    o verification: remove 2nd copy of input files and use script "prepare_run"
811      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
812    o mom_common/vecinv/fluxform: fix a few initialisation isssues
813    o profiles: fix for multithreaded case
814    
815    o diagnostics: rename few diags:
816      s/'PRESSURE'/'RCENTER '/g
817      s/'TICE    '/'oceFreez'/g
818      s/'TAUX    '/'oceTAUX '/g
819      s/'TAUY    '/'oceTAUY '/g
820      s/'SWFLUX  '/'oceQsw  '/g
821      s/DIFx/DFxE/g
822      s/DIFy/DFyE/g
823      and add few ocean-forcing diagnostics:
824      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
825    o modifications to pkg/seaice/growth.F and budget.F, which change results of
826      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
827      as actual snow thickness.  It now refers everywhere to effective snow
828      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
829    
830    checkpoint58r_post
831    o modifications to pkg/seaice/growth.F, which change results of
832      lab_sea experiment: fixes pertain to melting snow over open water, to
833      masking EVAP under sea ice, and to using the correct AREA variable for
834      computations of EVAP, PRECIP, HSNOW, and GHEFF
835    o add ability to read bathy, salt, and theta using MNC (off by def)
836    o add flooding algorithm and advection of HSNOW for pkg/seaice;
837      both are turned off by default and do no change any results
838    o seaice advection with pkg/thsice: a step toward the use of non-linear
839      advection scheme, but #ifdef or commented out for now (requires more EXCH).
840    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
841      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
842      in natl_box (affects results @ truncation level: update output.txt)
843    o multi-threading and IO:
844      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
845      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
846        (needed to work with SingleCpuIO): tested in all verif. exp.
847    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
848      affects the results (but none of the verification test uses this scheme).
849    o Adding some pkg/diagnostics capability to pkg/seaice
850      (will certainly be subject to changes)
851    o ctrl: adding new control variables:
852      lwflux, lwdown, evap, snowprecip, apressure, runoff
853    
854    checkpoint58q_post
855    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
856      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
857      high_res_cube configuration by 4% on Columbia.
858    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
859      add (in global_with_exf/code) a version of EXF_INTERP_READ without
860      dynamical allocation (seems to work in multi-threaded).
861    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
862      single CPU io) so that TAF does not have to see EESUPPORT.h
863    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
864    
865    checkpoint58p_post
866    o obcs: stop if obcs is used with useCDscheme = .true.
867    o shelfice:
868     - fix a sign error so that no slip at shelfice interface works
869     - remove stop for combination non-hydrostatic code and shelfice. That does
870       not mean, that the results are correct, but at least they are numerically
871       stable
872    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
873    o added adjoint exch routined for all exch*3d* routines
874      and updated flow directives
875    
876    checkpoint58o_post
877    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
878      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
879    o change controling S/R for writing pickup file (new S/R do_write_pickup)
880      and clean-up reading/writing of pickup files.
881    o fix local version of read/write pickup (NH part) in rotating_tank/code
882    o simplify EXCH interface:
883     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
884     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
885    o added the regrid package
886    o shelfice:
887     - add a simple boundary layer scheme to reduce noise
888     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
889    
890    checkpoint58n_post
891    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
892       local variable (not in common block).
893    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
894      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
895      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
896        to work with SingleCpuIO.
897    o add "_d 0" to real constant of pkg/cfc subroutines ;
898       update exp. cfc_exemple & tutorial_cfc_offline output files.
899    o multi-threading and IO:
900      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
901        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
902      - barrier before and after reading.
903      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
904      - avoid using MDS_WRITELOCAL for LAND pkg output.
905      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
906        common-block variables ; Allows multi-threading with master-thread IO.
907    o change default MAX_NO_THREADS from 32 to 4 ;
908      and stop cleanly when MAX_NO_THREADS is too small.
909    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
910    
911    checkpoint58m_post
912    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
913       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
914    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
915       keep global_ocean.90x40x15 (for AD testing) with former secondary test
916       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
917    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
918        add MITgcm_tutorials (= code + all the tutorials)
919    o ecco, option to compute cost for total ssh (mean+anom)
920    o consistent with addition of ptracer and ssh in pkg/profiles
921    o profiles: adding ptracer and ssh
922    o testreport: change multi-test output-file name
923      (from output.txt.{name} to output.{name}.txt)
924    o profiles: now ok for mutli-tiles case
925    o seaice: add 4 parameters for different advection schemes for area,
926      (effective) seaice thickness, enthalphy, and snow height. Their default
927      is the standard parameter SEAICEadvScheme
928    o calc_gw:
929     - add cosFacU in zonal viscous flux (harmonic.visc.).
930     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
931       of tutorial_plume_on_slope.
932    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
933    o calc_gw: true flux-form, account for horizontal grid spacing.
934      update rotating_tank results, but not plume_on_slope (affected at
935      truncation level, 11 digits).
936    
937    checkpoint58l_post
938    o calc_gw:
939     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
940     - remove side-drag for now (need to fix it); update plume_on_slope results.
941     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
942    o commit code to make SST/SSS weights spatially variable
943      (based on either variable in-situ or variable initial T/S weights)
944    o pkg/ecco:
945      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
946        now based on horizontally varying weights wthetaLev, wsaltLev
947      * cost_averagesflags now returns year indices in addition to day, month
948      * sflux balance is performed on annual basis
949        (sflxumm, sfluxmm2, bal_sfluxmm)
950      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
951        including separate counting and multipliers
952    o pkg/rbcs
953      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
954    
955    checkpoint58k_post
956    o testreport:
957     - always build in dir. "build" (if not there, mkdir build instead of building
958       & running in input)
959     - run in dir run (if it exists), in build otherwise.
960     - call prepare_run (if input/prepare_run exists)
961     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
962    o pkg/exf modifications to interpolation and rotation routines for more
963       reasonable treatment of North Pole singularity: for tracers North Pole
964       value is set to northernmost zonal-mean value, for zonal velocity it is
965       set to zero, and for meridional velocity it is set to northernmost value.
966    o pkg/exf/exf_check_range.F
967     - add tile index to diagnostics and move stop statement to the very
968       end of the routine.
969    o pkg/diagnostics: (diagnostics_main_init.F)
970      define title of isomorphic variables according to the current config.
971    o pkg/thsice with pkg/seaice dynamics:
972    - fix domain of computation (interior only, required for exf) and do exchanges
973    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
974    o towards a standard way of dealing with multi-threading in MONITOR
975      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
976    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
977       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
978    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
979    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
980    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
981       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
982    o tracer advection:
983     - clean-up and simplify calc_common_factors.F
984     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
985       advection subroutine (but still not used within DST advection S/R)
986    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
987    
988    checkpoint58j_post
989    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
990      from file (collects calls previously in FORWARD_STEP)
991    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
992    o adjoint store dir. adjusted accordingly
993    o genmake2
994      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
995    
996    checkpoint58i_post
997    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
998      on wind stress (SEAICEstressFactor defaults to 1.)
999    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1000      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1001    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1002      on CS-grid: no longer loosing mass.
1003    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1004    o pkg/ggl90: fix sloppy output and fix a bug
1005    o pkg/seaice: added SEAICEuseEVPpickup parameter
1006      - Set to false in order to start EVP solver with
1007        non-EVP pickup files when using SEAICEuseEVP
1008      - fix sign error in diffusion in seaice_calc_rhs
1009    
1010    checkpoint58h_post
1011    * Modifications for bottom topography control
1012      o replace hFacC by _hFacC at various places
1013      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1014      o add non-self-adjoint cg2d_nsa
1015      o update autodiff support routines
1016      o re-initialise hfac after ctrl_depth_ini
1017      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1018    * Adding verification for 5x5 box (4-layer) bottom topography control
1019    
1020    checkpoint58g_post
1021    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1022       used for mean seasonal cycle, mean diurnal cycle); add an example
1023       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1024    o pkg/ggl90:
1025      - add parameter (minimum surface kinetic energy)
1026      - fix bug (avoiding division by zero)
1027    o couple pkg/thsice to pkg/seaice:
1028      - modify advection in seaice to accomodate new scalar fields to be advected
1029      - only muliDimAdection scheme work with seaice/thsice
1030      - mapping of thsice-variables to seaice-variables, back and forth
1031      - does not break the verification experiments, but does not give the
1032        desired results either
1033    o pkg/seaice
1034      - make (default) second order advection a bit less confusing?
1035    
1036    checkpoint58f_post
1037    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1038      to pkg/seaice):
1039      - new routines thsice_map_exf and thsice_get_exf provide the interface
1040      - add an additional formal parameter to thsice_solve4temp
1041    o pkg/exf:
1042      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1043      - correct Stefan-Boltzmann constant
1044      - new parameter for longwave surface emittance
1045      - separate some stuff from exf_bulkformulae into new routines  
1046        exf_radiation, exf_wind
1047      - add new parameters and constants: longwave emissivity for ocean, ice
1048        and snow, evaporation parameters over ice
1049      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1050        either wind from stress or stress from wind
1051    o pkg/thSIce:
1052    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1053    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1054       and THSICE_CALC_THICKN
1055    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1056    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1057      to make debugging easier.
1058    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1059    o pkg/bulk_force:
1060      - clean-up comments and parameters ;
1061      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1062    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1063      generate new output for test-experiment: aim.5l_cs.thSI
1064    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1065      testreport accordingly
1066    
1067    checkpoint58e_post
1068    o SEAICE_CGRID adjoint done
1069    o R_STAR adjoint implemented.
1070      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1071      * need to sort out init. of h0facc, etc.
1072    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1073      to be able to use it in pure forward.
1074    
1075    checkpoint58d_post
1076    o upgrade simple test-experiment to tutorial example:
1077     step.1: duplicate the experiment and (step.2) will remove the old copy.
1078      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1079      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1080      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1081      tutorial_global_oce_biogeo    <- copy of dic_example
1082      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1083      tutorial_plume_on_slope       <- copy of plume_on_slope
1084      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1085      tutorial_global_oce_optim     <- empty for now (David ?)
1086      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1087     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1088    o correct a sign problem in cost_scat.F
1089    o obcs and ptracers: fix boundary conditions for advections schemes
1090      with larger stencil
1091    o thsice adjoint: start
1092    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1093      completeness
1094    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1095      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1096    o ptracers adjoint:
1097      * avoid extensive recomputatations
1098      * fix missing re-init. of gptr (missed by TAF)
1099    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1100      me to turn off the excessive output to STDOUT that this package produces
1101    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1102      and add those terms in Vector-Invariant formulation.
1103    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1104      if the control period (xx_hfluxperiod etc) is 0
1105    o in profiles pkg, clean routines and fix details
1106    o in ecco pkg, reading ssh data:
1107      fix problem in case the model does not start at iter0=0
1108    o fix mnc-pickup/restart for ptracers
1109    o new package prifiles:
1110      code to compute profile-based cost by Gael Forget
1111      (modifs in ecco, ctrl, autodiff)
1112    o Benign bug fix in initialization (spotted by M. Mazloff) of
1113      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1114    
1115    checkpoint58c_post
1116    o adjoint: finish NLFS adjoint and provide reference output in
1117      verification/global_ocean.90x40x15/results_ad_nlfs
1118    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1119      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1120      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1121      with SEAICE_CGRID defined.
1122    o move calendarDumps from "data" to "data.cal" and clean-up the code
1123      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1124    o add useEXF & useCAL flags (for now, set in hard-coded way)
1125    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1126      (were missing in NH mode, and wrong in quasihydrostatic mode).
1127      waiting for Chris updated version of calc_gw to add those CALLs.
1128    o fix bug in quasihydrostatic S/R ;
1129      add a test for this option: global_ocean.90x40x15.qshyd
1130    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1131      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1132    o add on/off flag useOffLine for package OFFLINE
1133    o seaice:
1134      - modify advection so that it works also on the C-grid
1135      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1136        problem in multi-tile runs with C-grid
1137      - add flags for clipping ice velocities and/or masking solver forcing
1138      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1139        C-grid solver
1140      - added a few comments to seaice_diffusion.F
1141      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1142        are now exclusive)
1143      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1144        required re-ordering the code a little:
1145       + make DAIRN global variable (defined in SEAICE)
1146       + move computation of the viscosities eta and zeta into a new separate
1147         routine (because I need to recompute them in seaice_ocean_stress.F)
1148    
1149    checkpoint58b_post
1150    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1151      update output.txt of exp. aim.5l_cs.thSI
1152    o various mnc cleanups and improvements:
1153      + shrink lookup tables by factor of ~4
1154      + better error reporting when running out of lookup space
1155      + able to handle longer path/file names (up to 500 chars)
1156    o adjoint:
1157      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1158      - TBD: "hidden" mom_vecinv recomp. in dynamics
1159    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1160     (allow to differentiate between forcing components using new integer flags:
1161      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1162     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1163    o ecco
1164      - enable trend removal from SSH anomaly obs.
1165    o adjoint
1166      - a fix for PmEpR when #undef EXACT_CONSERV
1167      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1168      - try to fix "hidden" recomp. in forward_step for NLFS
1169        (NLFS seems broken sometimes after I checked it in)
1170    o seaice:
1171     - add c-grid version of the dynamic solver:
1172       + three new routines that are the c-grid substitute lsr, dynsolver
1173         and ostres
1174       + put a few fields that were local to dynsolver into global common
1175         blocks, so that I can move the computation of stresses etc into
1176         seaice_lsr (saves coding but may break the adjoint).
1177     - replace more hardwired parameters by runtime parameters
1178     - add ice masks that mask the rhs of the implicit solvers where there
1179       is no ice (commented out in seaice_dynsolver, because i am not sure
1180       if this works properly), eventually this should replace the clipping
1181       of ice velocities in seaice_dynsolver to +/-40cm/s.
1182    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1183      include it only where its needed
1184    o move balancing of fluxes before the call of external_forcing_surf
1185    o seaice:
1186      - correct units of turning angles (now they are really in degrees)
1187      - move computation of GWATX/Y out of main routine into dynsolver
1188      - initialize GWATX/Y in seaice_init
1189    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1190      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1191    o seaice: add runtime flags for turning angles (default to zero)
1192    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1193      and trend from exf forcing and ctrl control adjustments
1194    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1195      (since checkpoint57x_post)
1196    o change the default rotation period to 86164.s = the Earth rotation
1197    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1198      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1199    o seaice advection: add code for choosing between the default (2nd order
1200      central differences) and multiDim advection schemes provided by
1201      pkg/generic_advdiff
1202    o seaice:
1203      - removed all references to SEAICE_GRID.h fields from
1204        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1205        (cubed-sphere configuration will change a little)
1206      - grid computations in seaice_init are obsolete now.
1207      - cleaned up code a little so that is easier to read (hopefully).
1208      - added new (better?) discretizations of default advection and diffusion
1209        (turn on with SEAICEuseFluxForm)
1210      - replace 1 in 3d global fields by kSurface in growth.F
1211      
1212    checkpoint58a_post
1213    o seaice:
1214      - bug fix in advect.F
1215    o shelfice:
1216      - separate shelfice load anomaly from pload (breaks with time
1217        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1218        Its default is 0., but it may be computed more cleverly from (unknown)
1219        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1220        done offline. A good approximation of the pressure load anomaly is
1221        necessary to avoid large initial adjustment processes underneath
1222        deep-reaching shelfice.
1223      - small fix in ISOMIP shelfice_thermodynamics
1224      - add more sophisticated thermodynamics of Hellmer (1989), this is
1225        now the default
1226      - give a few constants more intuitive names
1227    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1228      if bulk formulae are used in long integration (especially EmPmR). Turn
1229      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1230      if balancePrintMean, the imbalance that is substracted is printed to
1231      STDOUT.
1232    o fix bug (typo) in obcs_apply_eta.F
1233    o add a new package shelfice which enables us to model the circulation
1234      underneath shelf-ice with draughts of hundreds of meters.
1235     - works
1236     - to do: + include improved thermodynamics
1237              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1238                instead of new field kTopC
1239              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1240                instead of new field R_shelfIce and new code in ini_depth.F
1241                and ini_mask_etc.F?
1242              + adjust vertical mixing schemes?
1243    o seaice pkg:
1244     - add a cpp-flag to include a simple formula for a salinity dependent
1245       freezing point of sea water at the surface
1246     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1247       meridional stresses are now different (and hopefully correct)
1248    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1249       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1250       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1251    o pkg/diagnostics: add options and parameters for regional-statistics
1252       diagnostics ; define regions by reading a region-mask from a file
1253       (might add other options later)
1254    o pkg/bulk_force:
1255     - add option and parameters to use AIM surface-flux formulae.
1256     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1257       others forcing fields (defined in PARM05, parameter file "data") are loaded
1258       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1259     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1260     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1261     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1262       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1263     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1264    
1265    checkpoint58
1266    o add "--embed-source" option to genmake2 which, when the supporting
1267      tools can be compiled (as determined by genmake2) will turn on the
1268      embed_files package which then embeds the entire MITgcm source code
1269      (*.[fFhc] + Makefile) used for the build within the executable
1270      - requested by CNH but off by default
1271      - adds a paltry <9MB to the mitgcmuv executable in most cases
1272      - only writes the output when useEMBEDSRC in eedata is true
1273    o clean up 3-dim. relaxation codes:
1274      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1275      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1276      * Thanks to Tom Haine for testing!
1277    
1278    checkpoint57z_post
1279    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1280      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1281    o fix the pickup behavior for obcs in combination with ptracers
1282    o fix a bug in ptracers_external_fields_load
1283    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1284      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1285    o transfered surface NH pressure to eta field (if exactConserv).
1286    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1287         and update lab_sea output.txt file.
1288    o completing 3-dim. relaxation code: additional term
1289         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1290      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1291      * At compile time, in "EXF_OPTIONS.h" set
1292          #define  ALLOW_CLIMTEMP_RELAXATION
1293          #define  ALLOW_CLIMSALT_RELAXATION
1294      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1295          tauThetaClimRelax3Dim = 15552000.0,
1296          tauSaltClimRelax3Dim  = 15552000.0,
1297      * 3 cases:
1298          1) Use a constant-in-time 3-dim. field
1299          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1300          3) Real-time relax. to time-evolving prescribed field
1301    o Adding Laplacian-type smoothness constraint on
1302      initial and boundary (forcing) controls (ic, bc)
1303      * enable at compile-time via
1304        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1305      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1306      * Absolute scale somewhat unclear so far
1307      * no area weighting was included since no other cost term does so far
1308    
1309    checkpoint57y_post
1310    First step for a NLFS adjoint
1311    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1312    o new init. routines for calc_r_star, calc_surf_dr
1313    o still need to deal with ini_masks_etc
1314    o testreport seemed happy
1315    checkpoint57y_pre
1316    
1317    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1318    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1319    o add new offset feature to offline pkg (plus minor cleanup)
1320    o cfc fixes for final year of integration
1321    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1322      be in GCHEM_OPTIONS).
1323    
1324    checkpoint57x_post
1325    o fix testreport Pb in multiple test experiment.
1326    o cleanup our namelist syntax in verification:
1327      - make it more F95 standards compliant (some work still needed)
1328      - allows the vast majority of our tests to work with gfortran
1329    o Non-Hydrostatic:
1330     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1331     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1332    o Allow to apply AB on T,S rather than on AB(gT,gS):
1333     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1334     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1335       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1336     - need a "clever" read_pickup to restart from the other AB formulation
1337    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1338    o remove some unused variables (reduces number of compiler warnings)
1339    o adjoint
1340      * Disable useVariableViscosity for adjoint for time being
1341        (there are a number of extensive recomputations)
1342      * Initialize certain variables needed for adjoint
1343    
1344    checkpoint57w_post
1345    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1346                 fix the singleCpuIO RS version of MDSWRITEFIELD
1347       and add a WARNING if using globalFiles=T with multi-processors.
1348    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1349      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1350    o tracer advection scheme:
1351      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1352       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1353       was not very convenient).
1354      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1355       (further tests needed for the implicit DST & Flux-Limiter schemes).
1356    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1357      and sRef for convenience, handy, when you want to initialize
1358      ptracers in a large domain with a constant non-zero value. Also,
1359      untangle ptracers_init.F a little.
1360    
1361    checkpoint57v_post
1362    o change dome exp. to use variable viscosity in side-drag terms.
1363    o remove all the files from the cfc_offline test since they are now
1364      incorporated into tutorial_cfc_offline which has been producing
1365      identical results for a few days of testing
1366    o add new parameter: sideDragFactor to enable half-slip-side BC
1367      and change side-drag S/R to use viscosity from mom_calc_visc
1368      (can switch back by setting sideDragFactor=0.); affects results at
1369      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1370       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1371    o vorticity & strain are now computed without masking, to account for
1372      no-slip-side BC in variable viscosity calculation ; mask is applied
1373      anyway later on, before computing advection/coriolis terms.
1374    o modify exp4 to test new obcs support for reading from external files
1375      and for passive tracers
1376    o fix behavior of ptracers_monitor when monitor output is written to a
1377      netcdf-file; still not independent of monitor.F (writes in the same
1378      file).
1379    o change default value of tRef (put a uniform, meaningful value for ocean
1380      & atmos) and initialize sRef (was missing, as Martin mentioned).
1381    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1382      to be proportional to enstrophy dissipation length.  Thus,
1383       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1384      This is now consistent with Smagorinsky and with the manual.
1385    
1386    checkpoint57u_post
1387    o OBCS and PTRACERS: add open boundary support for passive tracers
1388      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1389        OB-values from file; this is not different from the way theta and salinity
1390        are treated
1391      - however, Orlanski-radiation conditions are not supported, and the model
1392        will stop if you use pTracers and Orlanski at the same time.
1393      - beefed up the rountine obcs_external_fields_load: now only those open
1394        boundary values are overwritten with values from files for which there
1395        are really files, otherwise the OB-fields remain untouched. This makes
1396        it possible to use different OBs at different ends of the domain (as
1397        with EXF)
1398    o reduce number of exch calls in shap_filt (s2).
1399    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1400      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1401    
1402    checkpoint57t_post
1403    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1404    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1405      same truncation, independent of the face number: affects affects several
1406      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1407    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1408      note that biharmonic viscosity + no-slip was not tested in any experiment.
1409    o fix bug in non-linear free-surf side-drag ; generate new output for
1410      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1411    o make mnc honor the writeBinaryPrec flag for most kinds of output
1412    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1413    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1414      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1415    o add brackets in multi-terms sum to get same truncation, independent of
1416      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1417      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1418    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1419      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1420      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1421      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1422      Suggested values of viscosity parameters found in mom_calc_visc.
1423      Many new viscosity diagnostics available.
1424    
1425    checkpoint57s_post
1426    o Add clearing-house for viscosity calculations, mom_calc_visc and
1427      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1428      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1429      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1430      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1431      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1432      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1433      ViscAhStrain and viscAhTension are now retired.
1434    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1435    o In response to JMC's bug report, genmake2 now ignores any soft-links
1436      that it finds in the *current* directory when searching for files.
1437      Soft-links found in any other source directories will still work as
1438      they did before.
1439    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1440      a C routine to unlimit the stack size
1441    o mnc-ify pkg/aim snapshot vars
1442    o mnc-ify pkg/land as requested by Daniel
1443    o various changes to mnc including:
1444      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1445      - output can now be grouped so that all files within a group
1446          change the ITER portion of their names in lock-step together
1447      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1448          and works with both EXCH1 and EXCH2 (but needs more testing)
1449      - writing works for all verification test cases w/ g77 on Linux
1450    
1451    checkpoint57r_post
1452    o make MNC variable initialization happen earlier
1453    o add diagnostics for (almost) each term of the momentum Eq.
1454    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1455    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1456    o remove MINIMAL_TAVE_OUTPUT option ;
1457      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1458    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1459      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1460    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1461    o add time-dependent SST, SSS control
1462    o cost terms in ecco/ modularized (new cost_generic.F)
1463    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1464    o new infrastructure for seaice model vs. obs misfits in seaice/
1465      * driver from the_main_loop.F is seaice_cost_driver.F
1466      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1467      * gradient check in Exp. 6a of natl_box_adjoint/
1468    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1469      (see README file)
1470    
1471    checkpoint57q_post
1472    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1473    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1474      - bug was reported by Jean-Michel and Ian Fenty
1475    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1476      update exp. cpl_aim+ocn output.
1477    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1478      Needed for high-res. runs with large global files
1479      to be able to limit tapelev size
1480    o Changed some tests for adjoint:
1481      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1482      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1483      * global_ocean.90x40x15/ back to default 3-level checkpointing
1484    o Modifications to enable scripted COMMON to MODULE conversion
1485      * verification/OpenAD/code/ has necessary scripts and description;
1486      * converts, compiles and runs successfully;
1487    
1488    checkpoint57p_post
1489    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1490    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1491      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1492    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1493    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1494      (was already the case for dissipation with mom_vecinv,
1495       and also the case for grad.PhiHyd when staggered-timeStep)
1496      This will allow to put dissipation out-off the AB time-stepping.
1497     Unfortunately, affects truncation error. Update output of exp. that "fails"
1498      (cg2d matching number) and leave the others for later: front_relax(10),
1499      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1500      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1501    
1502    checkpoint57o_post
1503    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1504      (2) its ready to be documented during the 20050801 DocFest
1505    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1506      for ideal_2D_oce and lab_sea on linux_ia32_g77
1507    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1508      in global1x1_tot/code_seaice_adj to access indices 32, 33
1509      (worth another tag)
1510    
1511    checkpoint57n_post
1512    o adding precip control xx_precip 32
1513    o adding swflux control xx_swflux 33
1514    o Replacing 10 forcing penalty cost routines by 1 generic.
1515    o Implementing partitioning in time-mean and variable adjustment
1516      for atmos. state.
1517    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1518  o in natl_box_adjoint:  o in natl_box_adjoint:
1519    * updated: results_bulk/    * updated exp 1 to 10
1520    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1521    o updated global1x1/*_seaice_adj/
1522      to incorporate latest changes
1523    o enable useSingleCpuIO for mdsio vector routines
1524      (applies in particular to tapelev I/O)
1525    o removed inefficient K-loop in all active_file*control*.F
1526    
1527  checkpoint57m_post  checkpoint57m_post
1528  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
