4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/grdchk: Add gradient check to etan0 perturbations.
8  o moved ptracer ctrl index 17 -> 32  o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
9    o pkg/autodiff: more flexibility in zeroadj.
10      model/src: modifying do_oceanic_phys.F accordingly.
11    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
12    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
13      special setup of gmredi for which the adjoint is stable
14      enough for parameter optimization.
15    o bridging the gap between eddy stress and GM.
16      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
17          along with a change in CPP option (now ALLOW_EDDYPSI).
18      -> when using GM w/ GM_AdvForm:
19          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
20          is applied either in the tracer Eq. or in momentum Eq.
21          depending on data.gmredi (intro. GM_InMomAsStress).
22      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
23      The key modifications are in model/src/taueddy_external_forcing.F
24      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
25    checkpoint59r
26    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
27      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
28      fix option to read coriolis(@ cell-corner) from files with CS-grid.
29    o pkg/mnc: add some attributes to standard 1D-coordinate variables
30    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
31      mass points, when using mnc for output
32      - add runtime parameter (missing_value, missing_value_int) to override
33        default (which is the value of getcon('UNDEF'))
34    o pkg/mnc: prepare mnc for the actual use of missing values with the
35      diagnostics package: small fix in mnc_cw_readwrite.template and more
36      initialisation of never used fields
37      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
38      versions
39    o pkg/thsice/thsice_ini_vars.F added default initial values so that
40      thermodynamics sea ice solver does not blow up when some initial fields
41      are missing.
42    o move from external_forcing_surf.F to ini_forcing.F
43      the p-coord. hack consisting in using pLoad to set phi0surf ;
44      update output of tutorial_global_oce_in_p (affected @ truncation level).
45    o Freshen up a bit hs94.1x64x5, notably:
46      remove rotationPeriod and tRef=5*0. (adjoint only), and add
47      exactConserv=.TRUE.
48    o pkg/generic_advdiff:
49      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
50      applies to files where Temperature & Salinity 2nd Order moments are used.
51    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
52      this uses a dynamically allocated internal state data structure
53      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
54      and requires a fortran 90 compiler
55    
56    checkpoint59q
57    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
58       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
59    o Refresh tutorial_global_oce_biogeo, notably:
60      - change bathymetry (put back seamounts in ACC, use hFacs)
61      - change EOS (POLY3 --> JMD95Z)
62      - use Bryan-Lewis vertical diffusivity
63      - use multidimensional advection
64      - remove old virtual virtual in dic pkg, now done through ptracer pkg
65      - change a couple of parameters in dic pkg
66    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
67    o pkg/obcs: change default to OBCSfixTopo = .true.,
68      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
69      - replace "debugMode" with "debugLevel .GE. debLevB"
70    o implementation of TAF directives for gchem,cfc,dic
71    o remove "exp5" (replaced by tutorial_deep_convection).
72    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
73      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
74      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
75      --> changes results in exp4, seaice_obcs
76    o tutorial_deep_convection :
77      update the set-up and increase resolution and domain size ; start
78      from pseudo initial conditions = output at t=120mn in order to see
79      something happening when running testreport.
80    o pkg/seaice: add os7mp as an advection scheme
81                  add check for advection schemes
82                  add a flag for restoring T and S underneath sea ice
83    o pkg/my82: add netcdf-support and diagnostics
84    o thsice pkg:
85      - Now hsMax limits snow height by turning it into ice following
86        flooding scheme (and now conserving energy)
87      - Slight rewriting of the formula in thsice_calc_thick.F
88      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
89      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
90    
91    checkpoint59p
92    o gchem / dic / cfc :
93      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
94      - add new parameter files: "data.dic" & "data.cfc" ;
95      - various re-arrangement in initialisation & header file ;
96      - fix tutorial_global_oce_biogeo for multi-threaded test.
97    o pkg/dic: test for "pickup_dic" file when restarting ;
98      if no pickup-file, can restart with a re-initialised pH (same as it did
99      before) providing pickupStrictlyMatch is set to False.
100    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
101      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
102    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
103      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
104    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
105     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
106       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
107    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
108       scheme to use for vorticty-term ;
109     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
110       (with default selectVortScheme, return to original discretisation)
111     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
112    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
113    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
114      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
115      also fix diagnostics VISCAHW & VISCA4W.
116    
117    checkpoint59o
118    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
119    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
120      move a few statemens out the main loop into separate loops
121    o pkg/shelfice:
122      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
123        (kg/m^2/s), does not break tests, because in verification/isomip,
124        rhoConstFresh=rhoConst (by accident)
125      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
126      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
127        new file model/src/seawater.F, so that they are available for all pkgs.
128      - convert potential temperature into in-situ temperature. This changes the
129        isomip tests => update tests
130    o add a flag writePickupAtEnd (default=true) to be able to suppress
131      writing a pickup at the last timestep
132    o tools/mpack-1.6 :
133      - disable automake (not working) and autoconf (not needed).
134      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
135        also cleaner with much less compilation warnings.
136    o pkg/profiles:
137      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
138      (for "less than 32 characters name" compiler requirement)
139    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
140      conditions that have a different sampling frequency than S/T/U/V obcs
141    o pkg/diagnostics (stats-diags):
142      - fix global Min/Max in case 1 processor get only empty tiles
143    o genmake2: replace (4 times)
144         make genmake_tc_1.o >> genmake_warnings 2>&1
145      with
146         COMM="$CC $CFLAGS -c genmake_tc_1.c"
147         echo $COMM >> genmake_warnings
148         $COMM >> genmake_warnings 2>&1
149      to make genmake2 always see the value of CC as specified in the optfile.
150    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
151      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
152      - modify verification advect_cs test to test SOM-advection on CS-grid.
153    o pkg/ctrl:
154      - Rewrite of ctrl_map_ini_ecco.F,
155        introducing a generic routine (ctrl_map_ini_gen.F).
156      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
157    
158    checkpoint59n
159    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
160      number in dedicate array "hdiag":
161      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
162        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
163      - many small changes (integer format) for large number of diagnostics
164      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
165        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
166    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
167      usingSphericalGrid, this allows to define the rotated grid coordinates
168      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
169      geographical coordinates according to the inverse of the rotation defined
170      by the Euler angles, so that Coriolis parameter and online-interpolation by
171      exf works with the geographical coordinates on XC/YC/XG/YG.
172      Naturally, this feature does not work with all packages, so some
173      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
174      profiles), because there the coordinates are assumed to be regular
175      spherical grid coordinates.
176    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
177      - introduce isopycnal diffusion coefficient control.
178    o tools/adjoint_options:
179      - additional control vector components.
180    o pkg/mnc: have mnc create marginally meaning full coordinate variables
181      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
182    o pkg/mypackage:
183      - add example of read/write pickup for state-var ;
184      - add entry points to the main code for state-vars diags & write-pickup.
185    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
186      transitions for useExfYearlyFields
187      - add new subroutine that determines the file to read from for
188        use*YearlyFields = .TRUE. and .FALSE.
189      - add a verification experiment to global_with_exf that tests
190        useExfYearlyFields with USE_EXF_INTERPOLATION defined
191    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
192      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
193      subroutines (which could be generated from a template, because they are
194      almost identical), for now they are included in obcs_prescribe_read.F for
195      simplicity
196    o pkg/exf:
197      - add a little more diagnostic to exf_interp_read (in analogy to
198        mds_read_field, can be turned off with debugLevel < debugLevA=1)
199      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
200        ugly but fast by unrolling short inner loops, inserting a unroll=8
201        directive in routine lagran, and splitting a loop and making do while the
202        outermost loop (the latter requires the intoduction of index arrays)
203    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
204    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
205      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
206    o verification/seaice_obcs: updated for restart test and latest options
207    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
208      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
209      for now this is only available for the C-grid code and also within
210      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
211    
212    checkpoint59m
213    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
214      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
215    o gad_som : fix flux output (& diagnostics) to have same units as other  
216      advection scheme fluxes (was previously multiplied by deltaT).  
217    o added verification/seaice_obcs both to test seaice open boundaries
218      and to provide an example matlab scrpt for generating them
219    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
220    o pkg/salt_plume: clean up salt_plume_frac.F to
221      remove redundancy in PlumeMethod 1 and 4
222    o pkg/kpp: added saltplume diagnostics
223    o pkg/obcs and pkg/seaice:
224      - do not set uice and vice to zero when OB*icefile are unspecified
225      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
226      - moved seaice tracer obcs after call to seaice_growth
227    o pkg/salt_plume: added various options for salt plume depth
228      criterion and for vertical distribution of the salt
229    
230    checkpoint59l
231    o pkg/ptracers: new version of ptracers pickup:
232      read meta file and write only fields which are needed to restart.
233      ( same logic as main pickup file ; also using pickupStrictlyMatch )
234    o pkg/seaice:
235      - add timescale for melting due to warm mixed layer as a means of
236        setting SEAICE_availHeatFrac more conveniently
237      - add a CPP-flag/runtime parameter check for flooding algorithm
238      - reformulated availHeat in seaice_growth.F to be independent of AREA
239    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
240      unit changes
241    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
242    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
243      SX vector computer.
244    o pkg/seaice:
245      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
246        seaice forcing fields can now be read only through pkg/exf
247      - removed some unused halos
248    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
249    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
250      or U/VICE from U/VWIND before computing U/VSTRESS
251    
252    checkpoint59k
253    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
254      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
255    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
256      all experiments pass when compile with un-initialised var. checking option.
257    o added pkg/salt_plume
258    o script to test restart (for now, in MITgcm_contrib/jmc_script)
259    o pkg/seaice: new read/write pickup version.
260      read meta file and write only fields which are needed to restart.
261      ( same logic as main pickup file ; also using pickupStrictlyMatch )
262    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
263    o lab_sea.hb87: modify the domain & update output.hb87.txt :
264      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
265      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
266      process. Fixed here by closing the domain at the Northern boundary.
267    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
268    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
269      a set of consecutive levels in/from a 3-D array.
270    o pkg/ptracers:
271      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
272      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
273    
274    checkpoint59j
275    o in pkgs: dic, obcs, offline, rbcs:
276      standard way to compute coeff. for time interpolation between 2 time reccords
277      which retains full precision (& make results less dependent on compiler).
278      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
279    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
280      packages instead of reading ice cover and wind speed separately
281    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
282     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
283      to allow to compile customized code before the update)
284    o cleaning-up:
285      - fix CPP instruction syntax in pkg/obcs
286      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
287        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
288      - fix some threads issue in IO parts.
289    o pkg/dic:
290      - add tons of "_d 0" (--> much better testreports !)
291       and then update outputs of tutorial_global_oce_biogeo
292    o pkg/mom_fluxform:
293      add a special version of momentum advection intended to conserve momentum
294      next to a bathymetry step or a coastline edge. (default = off = #undef)
295    o new read/write pickup version:
296      - for now, only implemented for main (mdsio) pickup file.
297      - write out only what is needed to restart; merge pickup_nh , pickup_ph
298        and main pickup together.
299      - read meta file; read only what is needed to restart; stop if a field
300        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
301        if it make sense (even if the restart is not perfect).
302      - if no meta file, assume that pickup to read corresponds exactly to
303        a pickup that would currently be written.
304      - read pickup written in the old format (until checkpoint59i) if it
305        recognizes an old meta file (no field-list).
306      - add a meta file in exp. which starts from a pickup: 2 cases:
307        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
308         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
309        b) a meta file describing the content of the associated pickup file
310         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
311    o pkg/mdsio & pkg/rw:
312      - new routine to read a meta file ; new set of routine to read
313        Multiple-fields file (with meta file).
314    o added open boundary conditions capability for seaice
315        HSNOW, HSALT, UICE, and VICE
316    
317    checkpoint59i
318    o adjoint:
319      * fix multiDimAdvection adjoint
320        (partial recomputation problem by TAF for fVerT(:,:,kDown)
321        and comlev1 size definition (maxpass vs. max. number of tracers)
322      * verification/global_ocean.90x45x15 adjoint now tests
323        NLFS and multiDimAdvection using DST3 (=30)
324      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
325    o pkg/kpp: add "_d 0" to real constant (if missing);
326      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
327      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
328    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
329      for internal parameters related to restart process (formerly from PARAMS.h)
330      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
331    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
332      as argument. (only atm2d & obcs write_pickup have not yet been updated)
333    o pkg/monitor:
334      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
335      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
336      - account for deep Atmosphere factor and density factor (anelastic)
337    o added open boundary conditions capability for seaice HEFF and AREA
338    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
339      thermodynamics
340      - requires a little reorganization, which affects the testreport results
341        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
342        so that now the conservative form is tested
343      - add a few comments
344    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
345    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
346    o add new diagnostics to seaice: advective, diffusive fluxes (only for
347      multidim-advection, for scheme 2 they are not filled) and transports,
348      thermodynamic growth rates
349    o change units of EmPmR (inside the code, + within coupling interface)
350      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
351      Affects results @ truncation level (cg2d match) and update output of
352       experiments: lab_sea(6), global_ocean.90x40x15(10),
353      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
354      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
355      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
356      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
357    
358    checkpoint59h
359    o pkg/exf:
360      - improve vectorization by moving if-statement out of loops in
361        exf_mapfields, exf_radiation
362      - exf_bulkformulae.F: introduce 2D fields and vectorize code
363    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
364    o testreport:
365      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
366        monitor & update offline_exf_seaice exp. output.
367      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
368    o pkg/seaice:
369      - bug fix in the evp solver: boundary conditions were affected be
370        masking of zMax/zMin (changes results)
371      - minor bug fix in boundary conditions in seaice_calc_strainrates
372        (changes results for no_slip)
373      - seaice_lsr.F: make interpolation of eta dependent on boundaries
374      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
375      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
376        stress formulation and no-slip boundary conditions
377    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
378      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
379    o pkg/seaice: a first HSALT time stepping equation has been checked in
380    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
381      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
382      without requiring DO-IF statements
383    o pkg/thsice:
384      use continuous power-law function for partition of energy between lateral
385      melting/freezing and thinning/thickening ; old code using step function
386      still available with #undef THSICE_FRACEN_POWERLAW
387      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
388    o testreport: change AD testing : check against results/output_adm.txt
389      using same scripts as for forward test.
390    
391    checkpoint59g
392    o adjoint testing: in preparation for changing testreport:
393      - output format: cost and grad written on separated lines
394      - ad output results in directory "results" (instead of "results_ad")
395    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
396    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
397    o pkg/ecco: allow user defined cost function contributions
398    o testreport:
399      Allow to choose (per experiment) the list of tested output variables
400       and the main variable (used to issue a pass/FAIL ) ;
401      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
402      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
403      Also modify printing of summary:
404       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
405       b) echo the list of tested variables in the individual summary.txt of
406          each experiment.
407    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
408      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
409      (but still depend on the tile decompostion of the domain).
410    o pkg/seaice: change a discretization detail to make the B-grid code
411      "more symmetric". This change is likely to remove all "ridges/leads" that
412      where quasi-aligned with the grid in B-grid solutions. It may also be
413      the solution to the stress coupling issues with the B-grid.
414    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
415      remove .cvsignore from input dir. (since testreport no longer run here).
416    o pkg/thsice:
417     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
418     - fix reshaping of sea-ice just after advection:
419       melt all the ice only if ice-volume is too small.
420     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
421       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
422     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
423    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
424      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
425    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
426      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
427      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
428      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
429      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
430      -> update output.txt
431    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
432     this affects truncation error: -> update output.txt of exp:
433      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
434      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
435    
436    checkpoint59f
437    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
438    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
439      a bounded range (in forward mode)
440    o pkg/ecco, ctrl, autodiff and mom_common:
441     internal parameter controls, completements of implementations
442    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
443    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
444      (not seem any difference in testing results).
445    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
446       at face corners.
447    o pkg/generic_advdiff:
448     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
449      loop range indices for computing vertical advection tendency
450      and do the calculation in the interior only (no overlap) ;
451      for now, only implemented for SOM advection (to save CPU time).
452     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
453    o exch2 adjoint
454      First set of changes:
455      - add exch2 hand-written adjoint templates
456      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
457        This will require cleanup in pkg/autodiff/*.F
458        (changed routines currently kept separate in verif. code/)
459      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
460        that used to hide exch2 or cubed-sphere specific code
461        (commented via 'cph-exch2')
462    o pkg/seaice
463      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
464    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
465       output of global_ocean.cs32x15.thsice .
466    
467    checkpoint59e
468    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
469      for B-grid vector (not yet tested) and C-grid vector (<- only used
470      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
471    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
472      (#ifdef ALLOW_SALT_PLUME)
473    o gather_2d/scatter_2d: removed halo regions
474    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
475      scheme and the corresponding test case (under front_relax dir). For now,
476      only available with Skew-flux form and not yet tested in realistic set-up.
477      adjoint: store directives updated, but gradient checks deteriorated,
478      so maybe GM/Redi adjoint is now broken.
479    o seaice adjoint
480      * add AREA, HEFF, HSNOW as control variable
481        (should not change lab_sea results)
482      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
483    o pkg/seaice:
484      * added computation of saltFlux in seaice_growth;
485        For time being, sea ice salinity is assumed constant
486        contribution of snow flooding to freshening of sea ice is neglected.
487        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
488        defaults to 0.0 in order to maintain backward compatibility.
489        Typical values for SEAICE_salinity are 4 to 10 g/kg.
490      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
491      * added SEAICE_availHeatFrac, which specifies fraction of surface level
492        heat content used to melt or grow ice
493      * commented out cap of HICE: it helps keep ice thinner
494      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
495      * applied OBCS T/S mask to HEFFM sea ice mask
496    
497    checkpoint59d
498    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
499     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
500     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
501    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
502     and change default value of parameter "GM_Small_Number";
503     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
504       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
505       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
506    o pkg/ecco: cost function when applying pkg/smooth to controls
507    o pkg/ctrl: add forcingPrecond run time parameter
508    o pkg/seaice:
509     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
510     - fix bug in metric terms of u-equation in LSR solver (implicit part),
511       changes verification/lab_sea
512     - rearrange implicit part of u-equation in LSR solver to make it easier to
513       read, understand, and debug. This causes changes at the truncation level.
514     - fix (serious) bug in the boundary conditions (sign error in the implicit
515       part) of the LSR solver. Changes all LSR results.
516     - fixed problem with HSNOW initialization to avoid thick snow when AREA
517       is initilized with small values - does not change lab_sea results.
518     - added HsnowFile initialization capability
519    o pkg/smooth: addition to model/src and pkg/ctrl so allow
520     initialization of pkg/smooth and application to control vector
521    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
522    o dependencies: pkg/profiles requires pkg/cal
523    o pkg/profiles:
524     - added option ALLOW_PROFILES_GENERICGRID
525         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
526         that interpolation information (grid points and coefficients) is provided
527         within the netcdf input files.
528         -> sample matlab scripts can be found in MITgcm_contrib/gael
529         that allow you to prepare netcdf input files.
530     - also modified: cleaner include statements, cleaner error print statements,
531       cleaner stops when error, and more tests of the netcdf input files consistency.
532    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
533    o pkg/seaice:
534     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
535       requires a new routine: seaice_diagnostics_fill.F
536     - make sure that seaice does not move if not forced (pressure replacement
537       method, Hibler and Ip, 1995), changes results
538     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
539     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
540       It is turned off by default (=-1.), because it changes the results.
541     - make it possible to read AREA from a file, too.
542    
543    checkpoint59c
544    o add S/R and diagnostics for oceanic mixed-layer depth
545    o move GMRedi call after all vertical mixing schemes (including KPP)
546    o pkg/thsice:
547     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
548      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
549    o pkg/obcs:
550     - bug fix for balance code
551    o pkg/seaice:
552      - allow values of SEAICE_elasticParm > 1
553      - add new parameter SEAICE_evpTauRelax as an alternative
554        to SEAICE_elasticParm
555      - make lsr boundary conditions free slip (by default), changes result
556      - add code for no slip boundary conditions for lsr
557      - set minimum of zeta to zero (and not 4e8) (changes results)
558      - add a cap on AREA after advecting AREA if seaice_growth is not called
559    o change calculation of Visbeck K:
560      - no longer depend on tapering scheme; instead, compute slope (limited
561        by GM_maxSlope). this is equivalent to what was comuted before with
562        clipping or linear tappering.
563      - fix vertical averaging (wrong by 1/2 level)
564      - leave the old version (but will not be maintained) within
565        #ifdef OLD_VISBECK_CALC / #endif
566      - update output of exp. ideal_2D_oce
567    o change error catch in calc_r_star to improve vectorization
568    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
569      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
570    o adjoint:
571      Re-organized adjoint checkpointing according to Matt Mazloff
572      (but with modifs/completions/cleanups)
573      Storing is now bundled into large arrays to optimized I/O
574      (and second step in cleanup of the_main_loop)
575    
576    checkpoint59b
577    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
578      - export/import (between ocean & coupler) fields needed for ocean DIC.
579    o pkg/seaice:
580      - get rid of three more exchanges seaice_calc_viscosities (required
581        different loop boundaries in seaice_lsr and seaice_ocean_stress)
582      - bug fix in seaice_ocean_stress (update of lab_sea required)
583      - reduce loop boundaries to necessary minimum also in seaice_evp
584      - go back to the old way of computing deltaC/Z as the adjoint likes that
585        better
586    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
587      passive tracer to an Age Tracer) + update output.txt
588    o pkg/exf:
589      - implement A-grid / C-grid selection for wind-stress input files.
590      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
591      for now, in exf_bulk_largeyeager04.F only :
592      - change implementation for case where windspeed + 2. components wind-stress
593        are read-in. AND use rhoConstFresh to convert evap.
594    o pkg/seaice:
595      - use correct EXCH_UV for wind-forcing (on A-grid).
596      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
597        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
598    o pkg/exf:
599      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
600      EXF_INTERPOLATION:
601      - merge global_with_exf/code version of exf_interp_read.F
602        to the main code ;
603      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
604        reading the file ; Important: This options needs to be defined to recover
605        previous code.
606        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
607      - no longer loose real*8 precision along the way when using exf_iprec=64.
608    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
609      - change discretisation of evp-solver in order to avoid another exchange
610        (changes lab_sea) and clean up a little
611      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
612        help the adjoint (this also changes the results slightly)
613      - add a few "_d 0" where they had been missing in seaice_evp.F
614      - cleaning up: remove unused seaice_calc_rhs.F
615    o pkg/exf: some cleaning-up:
616      - change various "constants" into runtime parameters
617      - cleaned-up Large&Yeager04 routine which should eventually
618        replace exf_bulkformulae.F (changed names of S/R and CPP)
619        and merged various ALLOW_ATM_WIND options
620     only used with thsice pkg (in thsice_get_exf.F):
621      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
622        which are used when useStabilityFct_overIce=TRUE (= the default)
623      - change default values of ice & snow emissivity and scale downward LW
624        by ice & snow emissivity.
625    o pkg/thsice:
626     fix few little problems, in thsice_calc_thickn.F:
627      - growth vertically (and not laterally) if iceFrac == iceMaskMax
628      - melt only laterally if hIce < hThinIce (as the comments say)
629      and in thsice_extend.F:
630      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
631      - start to form ice as soon as the minimum ice-volume is reachable.
632     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
633      and cpl_aim+ocn
634    o pkg/kpp
635     - move computation of surface related input fields to KPP into a new
636       subroutine kpp_forcing_surf.F
637     - remove wrong (within bi,bj loops) EXCH calls.
638     - little cleaning (add argument myThid in last position, cvs header ...)
639     - for now, fix conservation problem by exchanging KPPviscAz (may not
640       be the best fix)
641    o pkg/seaice
642     - check for inconsistent evp parameter/cpp-flag combination
643     - remove leftover errIO flat for obsolete name list error handling
644    o OpenAD
645     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
646    
647    checkpoint59a
648    o pkg/seaice: some parameter clarifications and a little bit of clean up
649    o pkg/thsice: rename run-time parameters:
650       himin       -> hIceMin
651       himin0      -> hThinIce
652       hihig       -> hThickIce
653       i0          -> i0swFrac
654       transCoef   -> bMeltCoef
655       frac_energy -> fracMelting
656      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
657       with default values (for now) that do not change the results.
658      remove old version of thsice vars advection in pkg/seaice.
659    o in FFIELDS.h:
660      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
661      - make pLoad & sIceLoad always available (but still only used if
662         ATMOSPHERIC_LOADING is #define).
663    o pkg/kpp: replaced _KPP_RL with _RL
664    o bug fixes for vertical diffusivity computations when both KPP and
665        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
666        are no longer updating the vertical diffusivity array
667        (passed as argument) but are (re-) setting those arrays.
668    o pkg/seaice: fix bug in evp solver, while doing that
669      - change (improve?) discretization of stress computations for both
670        cgrid-lsr and evp solver
671      - add a new routine to compute strain rates
672      - the above changes lab_sea results
673      - add no slip conditions for evp solver (off by default), lsr-version
674        may follow
675      - fix exchange for shear at Z-points (does not change lab_sea)
676      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
677        (to force the user to pick a time step since there is not "safe" way
678        of choosing it)
679      - add principal stress diagnostics
680      - rearrange fields for evp a little to avoid having to call a: too many
681        exchanges and b: exchanges for stress trensor components which we do
682        not have.
683      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
684        of evp, complete rewrite for lsr case (latter is does not yet work
685        in all cases)
686    o pkg/kpp: add code to have mixing in shelf ice caverns
687      - add myThid to all kpp routines (long overdue)
688    
689    checkpoint59
690    o pkg/exf:
691      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
692        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
693      - move exf header files from lower_case.h to UPPER_CASE.h ;
694        add missing cvs Header & Name
695      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
696      - add namelist param. selectStressGridPosition, exf_monFreq
697      - retire many _CLIM routines, and remove data.exf_clim
698        + params moved to data.exf
699        + climsst, climsss now handled by exf_set_gen, i.e.
700          climss?period=0 refers to constant field,
701          climss?period=-12 to monthly forcing
702      - split up namelists in data.exf
703    o pkg/seaice:
704      - remove seaice_exch and seaice_exch_uv
705      - remove superfluous exchange of theta
706      - add myThid to seaice_budget_ocean/ice
707      - add new interface for atmospheric wind forcing (C-grid only)
708        + new routine
709        + two new field (taux, tauy for stress over ice)
710        + removed one global field (DAIRN) for C-grid case only
711    o pkg/thsise
712      - 2nd set of modifs for thsice adjoint in conjunction with exf
713    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
714    
715    checkpoint58y_post
716    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
717      vertical diffusivity, similar to that in MOM4; turned on using
718      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
719      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
720    o Added capability for 3D specification of background vertical diffusion
721      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
722      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
723      "data" file that contains the 3D vertical diffusivity coefficients.
724    o ice dynamics (pkg/seaice) with thsice thermodynamics:
725      - add code within pkg thsice to advect & diffuse sea-ice fields
726      similar to (and will replace) what has been added in  seaice_advdiff.F,
727      but: - conserving Mass, Heat & Salt.
728           - better when using non-linear advection scheme (not yet fully tested)
729           - can also be used in atmospheric set-up (for now, only the diffusion).
730    
731    checkpoint58x_post
732    o IO option for global-file compact format:
733      - add options when generating topology (utils/exch2/matlab-topology-generator)
734      - add I/O capability (pkg/mdsio).
735      - adapt utils/matlab/rdmds.m to read this format.
736      for now long-line format not yet supported by pkg/mdsio (& exch2).
737    o shelfice: add a few diagnostics
738    
739    checkpoint58w_post
740    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
741      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
742      (and replace horiVertRatio in NH code).
743      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
744                         and tutorial_plume_on_slope (sensitive to truncation)
745    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
746      directly to drive seaice model (C-grid only)
747    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
748     - reintroduce computation of wind from stress,
749     - compute tau (in exf_bulkformulae.F) from windstress averaged to
750       mass points to avoid tau = 0
751     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
752    o rdmnc.m: make it work with "global" files created with gluemnc
753    o rdmnc.m : some improvements in dealing with singleton dimension
754      (tested on all testreport mnc output files).
755    o genmake2: disable pkg/profiles if netcdf test fails.
756    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
757    o move call to cal_readparms up to make calendar parameters/variable available
758      to all packages
759    
760    checkpoint58v_post
761    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
762      useDynP_inEos_Zc tested.
763    o pkg/exf: changes to properly interpolate/mask/scale initial fields
764    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
765      and portions thereof.  See read_cs.txt for description and examples.
766    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
767      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
768      following the great-circle arc between those 2 points.
769    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
770      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
771    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
772     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
773     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
774     - still needs work (not working with some options ; efficiency to improve)
775       and serious testing.
776     - use this scheme for temperature & salinity in 2 advection test exp.:
777       advect_xy & advect_xz, respectively.
778    
779    checkpoint58u_post
780    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
781    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
782    o testreport: add option "-skipdir" to skip some test.
783    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
784      momentum calculation.
785    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
786    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
787      remove checkpoint.F and the_correction_step.F (no longer used);
788      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
789    o add option (linFSConserveTr) to correct for tracer source/sink due to
790      Linear Free surface
791    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
792    o pkg/thsice: fix reading mnc-pickups
793    
794    checkpoint58t_post
795    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
796    o pkg/mdsio:
797     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
798       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
799       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
800     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
801     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
802       either MDS_READ_FIELD or MDS_WRITE_FIELD )
803     - new S/R (to replace MDSWRITEMETA), which allows to write more
804       informations (variable names, time ...) to meta files.
805     - modify rdmds.m to give back the meta file content.
806    o pkg/diagnostics: change vertical interpolation to be safer, and more
807       flexible (define p-levels to interpolate to in data.diagnostics);
808      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
809       diagnostic pointer.
810    o pkg/seaice: more cleaning up of seaice_growth, added many comments
811    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
812    o fix multi-category seaice:
813     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
814       SEAICE_MULTICATEGORY
815     - fix short wave heat flux
816    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
817       and allow to use EVP solver. Change forward lab_sea: test both EVP
818       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
819    o Initial check-in of lab_sea adjoint
820      (very similar to natl_box_adjoint/code_seaice)
821      * used C-grid and EVP solver
822      * used KPP, GM/Redi
823      * uses inAdExact=.TRUE.
824      * gradient checks fail for both ADM and TLM
825        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
826        f.d. gradients actually seem more problematic than ADM, TLM gradients;
827        issue is related to forward mismatch between g77 an ifort
828    o pkg/seaice: overhaul of thermodynamics
829     - growth.F and groatb.F are replaced by new routine seaice_growth.F
830     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
831     - move a few global fields out of SEAICE.h into seaice_growth.F and
832       make them 2D (FICE/QNETO/ ...)
833     - remove FO (it is the same as QNETO)
834     - introduce a few local fields to avoid modifying external fields such
835       as atemp, etc.
836    
837    checkpoint58s_post
838    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
839      changed exf_set_gen.F so that
840        genperiod=0 means input file is one time-constant field and
841        genperiod=-12 means input file contains 12 monthly means
842    o CG2D: use pre-computed solver main-diagonal (stored in common block);
843      this affects truncation error ; generate new output file for exp. which
844      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
845        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
846        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
847        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
848        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
849        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
850    o start implementation of deep-atmosphere and anelastic formulation
851    o verification: remove 2nd copy of input files and use script "prepare_run"
852      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
853    o mom_common/vecinv/fluxform: fix a few initialisation isssues
854    o profiles: fix for multithreaded case
855    
856    o diagnostics: rename few diags:
857      s/'PRESSURE'/'RCENTER '/g
858      s/'TICE    '/'oceFreez'/g
859      s/'TAUX    '/'oceTAUX '/g
860      s/'TAUY    '/'oceTAUY '/g
861      s/'SWFLUX  '/'oceQsw  '/g
862      s/DIFx/DFxE/g
863      s/DIFy/DFyE/g
864      and add few ocean-forcing diagnostics:
865      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
866    o modifications to pkg/seaice/growth.F and budget.F, which change results of
867      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
868      as actual snow thickness.  It now refers everywhere to effective snow
869      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
870    
871    checkpoint58r_post
872    o modifications to pkg/seaice/growth.F, which change results of
873      lab_sea experiment: fixes pertain to melting snow over open water, to
874      masking EVAP under sea ice, and to using the correct AREA variable for
875      computations of EVAP, PRECIP, HSNOW, and GHEFF
876    o add ability to read bathy, salt, and theta using MNC (off by def)
877    o add flooding algorithm and advection of HSNOW for pkg/seaice;
878      both are turned off by default and do no change any results
879    o seaice advection with pkg/thsice: a step toward the use of non-linear
880      advection scheme, but #ifdef or commented out for now (requires more EXCH).
881    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
882      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
883      in natl_box (affects results @ truncation level: update output.txt)
884    o multi-threading and IO:
885      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
886      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
887        (needed to work with SingleCpuIO): tested in all verif. exp.
888    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
889      affects the results (but none of the verification test uses this scheme).
890    o Adding some pkg/diagnostics capability to pkg/seaice
891      (will certainly be subject to changes)
892    o ctrl: adding new control variables:
893      lwflux, lwdown, evap, snowprecip, apressure, runoff
894    
895    checkpoint58q_post
896    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
897      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
898      high_res_cube configuration by 4% on Columbia.
899    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
900      add (in global_with_exf/code) a version of EXF_INTERP_READ without
901      dynamical allocation (seems to work in multi-threaded).
902    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
903      single CPU io) so that TAF does not have to see EESUPPORT.h
904    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
905    
906    checkpoint58p_post
907    o obcs: stop if obcs is used with useCDscheme = .true.
908    o shelfice:
909     - fix a sign error so that no slip at shelfice interface works
910     - remove stop for combination non-hydrostatic code and shelfice. That does
911       not mean, that the results are correct, but at least they are numerically
912       stable
913    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
914    o added adjoint exch routined for all exch*3d* routines
915      and updated flow directives
916    
917    checkpoint58o_post
918    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
919      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
920    o change controling S/R for writing pickup file (new S/R do_write_pickup)
921      and clean-up reading/writing of pickup files.
922    o fix local version of read/write pickup (NH part) in rotating_tank/code
923    o simplify EXCH interface:
924     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
925     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
926    o added the regrid package
927    o shelfice:
928     - add a simple boundary layer scheme to reduce noise
929     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
930    
931    checkpoint58n_post
932    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
933       local variable (not in common block).
934    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
935      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
936      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
937        to work with SingleCpuIO.
938    o add "_d 0" to real constant of pkg/cfc subroutines ;
939       update exp. cfc_exemple & tutorial_cfc_offline output files.
940    o multi-threading and IO:
941      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
942        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
943      - barrier before and after reading.
944      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
945      - avoid using MDS_WRITELOCAL for LAND pkg output.
946      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
947        common-block variables ; Allows multi-threading with master-thread IO.
948    o change default MAX_NO_THREADS from 32 to 4 ;
949      and stop cleanly when MAX_NO_THREADS is too small.
950    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
951    
952    checkpoint58m_post
953    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
954       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
955    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
956       keep global_ocean.90x40x15 (for AD testing) with former secondary test
957       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
958    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
959        add MITgcm_tutorials (= code + all the tutorials)
960    o ecco, option to compute cost for total ssh (mean+anom)
961    o consistent with addition of ptracer and ssh in pkg/profiles
962    o profiles: adding ptracer and ssh
963    o testreport: change multi-test output-file name
964      (from output.txt.{name} to output.{name}.txt)
965    o profiles: now ok for mutli-tiles case
966    o seaice: add 4 parameters for different advection schemes for area,
967      (effective) seaice thickness, enthalphy, and snow height. Their default
968      is the standard parameter SEAICEadvScheme
969    o calc_gw:
970     - add cosFacU in zonal viscous flux (harmonic.visc.).
971     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
972       of tutorial_plume_on_slope.
973    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
974    o calc_gw: true flux-form, account for horizontal grid spacing.
975      update rotating_tank results, but not plume_on_slope (affected at
976      truncation level, 11 digits).
977    
978    checkpoint58l_post
979    o calc_gw:
980     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
981     - remove side-drag for now (need to fix it); update plume_on_slope results.
982     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
983    o commit code to make SST/SSS weights spatially variable
984      (based on either variable in-situ or variable initial T/S weights)
985    o pkg/ecco:
986      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
987        now based on horizontally varying weights wthetaLev, wsaltLev
988      * cost_averagesflags now returns year indices in addition to day, month
989      * sflux balance is performed on annual basis
990        (sflxumm, sfluxmm2, bal_sfluxmm)
991      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
992        including separate counting and multipliers
993    o pkg/rbcs
994      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
995    
996    checkpoint58k_post
997    o testreport:
998     - always build in dir. "build" (if not there, mkdir build instead of building
999       & running in input)
1000     - run in dir run (if it exists), in build otherwise.
1001     - call prepare_run (if input/prepare_run exists)
1002     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1003    o pkg/exf modifications to interpolation and rotation routines for more
1004       reasonable treatment of North Pole singularity: for tracers North Pole
1005       value is set to northernmost zonal-mean value, for zonal velocity it is
1006       set to zero, and for meridional velocity it is set to northernmost value.
1007    o pkg/exf/exf_check_range.F
1008     - add tile index to diagnostics and move stop statement to the very
1009       end of the routine.
1010    o pkg/diagnostics: (diagnostics_main_init.F)
1011      define title of isomorphic variables according to the current config.
1012    o pkg/thsice with pkg/seaice dynamics:
1013    - fix domain of computation (interior only, required for exf) and do exchanges
1014    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1015    o towards a standard way of dealing with multi-threading in MONITOR
1016      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1017    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1018       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1019    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1020    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1021    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1022       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1023    o tracer advection:
1024     - clean-up and simplify calc_common_factors.F
1025     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1026       advection subroutine (but still not used within DST advection S/R)
1027    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1028    
1029    checkpoint58j_post
1030    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1031      from file (collects calls previously in FORWARD_STEP)
1032    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1033    o adjoint store dir. adjusted accordingly
1034    o genmake2
1035      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1036    
1037    checkpoint58i_post
1038    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1039      on wind stress (SEAICEstressFactor defaults to 1.)
1040    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1041      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1042    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1043      on CS-grid: no longer loosing mass.
1044    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1045    o pkg/ggl90: fix sloppy output and fix a bug
1046    o pkg/seaice: added SEAICEuseEVPpickup parameter
1047      - Set to false in order to start EVP solver with
1048        non-EVP pickup files when using SEAICEuseEVP
1049      - fix sign error in diffusion in seaice_calc_rhs
1050    
1051    checkpoint58h_post
1052    * Modifications for bottom topography control
1053      o replace hFacC by _hFacC at various places
1054      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1055      o add non-self-adjoint cg2d_nsa
1056      o update autodiff support routines
1057      o re-initialise hfac after ctrl_depth_ini
1058      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1059    * Adding verification for 5x5 box (4-layer) bottom topography control
1060    
1061    checkpoint58g_post
1062    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1063       used for mean seasonal cycle, mean diurnal cycle); add an example
1064       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1065    o pkg/ggl90:
1066      - add parameter (minimum surface kinetic energy)
1067      - fix bug (avoiding division by zero)
1068    o couple pkg/thsice to pkg/seaice:
1069      - modify advection in seaice to accomodate new scalar fields to be advected
1070      - only muliDimAdection scheme work with seaice/thsice
1071      - mapping of thsice-variables to seaice-variables, back and forth
1072      - does not break the verification experiments, but does not give the
1073        desired results either
1074    o pkg/seaice
1075      - make (default) second order advection a bit less confusing?
1076    
1077    checkpoint58f_post
1078    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1079      to pkg/seaice):
1080      - new routines thsice_map_exf and thsice_get_exf provide the interface
1081      - add an additional formal parameter to thsice_solve4temp
1082    o pkg/exf:
1083      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1084      - correct Stefan-Boltzmann constant
1085      - new parameter for longwave surface emittance
1086      - separate some stuff from exf_bulkformulae into new routines  
1087        exf_radiation, exf_wind
1088      - add new parameters and constants: longwave emissivity for ocean, ice
1089        and snow, evaporation parameters over ice
1090      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1091        either wind from stress or stress from wind
1092    o pkg/thSIce:
1093    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1094    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1095       and THSICE_CALC_THICKN
1096    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1097    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1098      to make debugging easier.
1099    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1100    o pkg/bulk_force:
1101      - clean-up comments and parameters ;
1102      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1103    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1104      generate new output for test-experiment: aim.5l_cs.thSI
1105    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1106      testreport accordingly
1107    
1108    checkpoint58e_post
1109    o SEAICE_CGRID adjoint done
1110    o R_STAR adjoint implemented.
1111      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1112      * need to sort out init. of h0facc, etc.
1113    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1114      to be able to use it in pure forward.
1115    
1116    checkpoint58d_post
1117    o upgrade simple test-experiment to tutorial example:
1118     step.1: duplicate the experiment and (step.2) will remove the old copy.
1119      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1120      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1121      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1122      tutorial_global_oce_biogeo    <- copy of dic_example
1123      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1124      tutorial_plume_on_slope       <- copy of plume_on_slope
1125      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1126      tutorial_global_oce_optim     <- empty for now (David ?)
1127      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1128     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1129    o correct a sign problem in cost_scat.F
1130    o obcs and ptracers: fix boundary conditions for advections schemes
1131      with larger stencil
1132    o thsice adjoint: start
1133    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1134      completeness
1135    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1136      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1137    o ptracers adjoint:
1138      * avoid extensive recomputatations
1139      * fix missing re-init. of gptr (missed by TAF)
1140    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1141      me to turn off the excessive output to STDOUT that this package produces
1142    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1143      and add those terms in Vector-Invariant formulation.
1144    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1145      if the control period (xx_hfluxperiod etc) is 0
1146    o in profiles pkg, clean routines and fix details
1147    o in ecco pkg, reading ssh data:
1148      fix problem in case the model does not start at iter0=0
1149    o fix mnc-pickup/restart for ptracers
1150    o new package prifiles:
1151      code to compute profile-based cost by Gael Forget
1152      (modifs in ecco, ctrl, autodiff)
1153    o Benign bug fix in initialization (spotted by M. Mazloff) of
1154      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1155    
1156    checkpoint58c_post
1157    o adjoint: finish NLFS adjoint and provide reference output in
1158      verification/global_ocean.90x40x15/results_ad_nlfs
1159    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1160      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1161      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1162      with SEAICE_CGRID defined.
1163    o move calendarDumps from "data" to "data.cal" and clean-up the code
1164      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1165    o add useEXF & useCAL flags (for now, set in hard-coded way)
1166    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1167      (were missing in NH mode, and wrong in quasihydrostatic mode).
1168      waiting for Chris updated version of calc_gw to add those CALLs.
1169    o fix bug in quasihydrostatic S/R ;
1170      add a test for this option: global_ocean.90x40x15.qshyd
1171    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1172      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1173    o add on/off flag useOffLine for package OFFLINE
1174    o seaice:
1175      - modify advection so that it works also on the C-grid
1176      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1177        problem in multi-tile runs with C-grid
1178      - add flags for clipping ice velocities and/or masking solver forcing
1179      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1180        C-grid solver
1181      - added a few comments to seaice_diffusion.F
1182      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1183        are now exclusive)
1184      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1185        required re-ordering the code a little:
1186       + make DAIRN global variable (defined in SEAICE)
1187       + move computation of the viscosities eta and zeta into a new separate
1188         routine (because I need to recompute them in seaice_ocean_stress.F)
1189    
1190    checkpoint58b_post
1191    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1192      update output.txt of exp. aim.5l_cs.thSI
1193    o various mnc cleanups and improvements:
1194      + shrink lookup tables by factor of ~4
1195      + better error reporting when running out of lookup space
1196      + able to handle longer path/file names (up to 500 chars)
1197    o adjoint:
1198      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1199      - TBD: "hidden" mom_vecinv recomp. in dynamics
1200    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1201     (allow to differentiate between forcing components using new integer flags:
1202      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1203     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1204    o ecco
1205      - enable trend removal from SSH anomaly obs.
1206    o adjoint
1207      - a fix for PmEpR when #undef EXACT_CONSERV
1208      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1209      - try to fix "hidden" recomp. in forward_step for NLFS
1210        (NLFS seems broken sometimes after I checked it in)
1211    o seaice:
1212     - add c-grid version of the dynamic solver:
1213       + three new routines that are the c-grid substitute lsr, dynsolver
1214         and ostres
1215       + put a few fields that were local to dynsolver into global common
1216         blocks, so that I can move the computation of stresses etc into
1217         seaice_lsr (saves coding but may break the adjoint).
1218     - replace more hardwired parameters by runtime parameters
1219     - add ice masks that mask the rhs of the implicit solvers where there
1220       is no ice (commented out in seaice_dynsolver, because i am not sure
1221       if this works properly), eventually this should replace the clipping
1222       of ice velocities in seaice_dynsolver to +/-40cm/s.
1223    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1224      include it only where its needed
1225    o move balancing of fluxes before the call of external_forcing_surf
1226    o seaice:
1227      - correct units of turning angles (now they are really in degrees)
1228      - move computation of GWATX/Y out of main routine into dynsolver
1229      - initialize GWATX/Y in seaice_init
1230    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1231      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1232    o seaice: add runtime flags for turning angles (default to zero)
1233    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1234      and trend from exf forcing and ctrl control adjustments
1235    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1236      (since checkpoint57x_post)
1237    o change the default rotation period to 86164.s = the Earth rotation
1238    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1239      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1240    o seaice advection: add code for choosing between the default (2nd order
1241      central differences) and multiDim advection schemes provided by
1242      pkg/generic_advdiff
1243    o seaice:
1244      - removed all references to SEAICE_GRID.h fields from
1245        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1246        (cubed-sphere configuration will change a little)
1247      - grid computations in seaice_init are obsolete now.
1248      - cleaned up code a little so that is easier to read (hopefully).
1249      - added new (better?) discretizations of default advection and diffusion
1250        (turn on with SEAICEuseFluxForm)
1251      - replace 1 in 3d global fields by kSurface in growth.F
1252      
1253    checkpoint58a_post
1254    o seaice:
1255      - bug fix in advect.F
1256    o shelfice:
1257      - separate shelfice load anomaly from pload (breaks with time
1258        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1259        Its default is 0., but it may be computed more cleverly from (unknown)
1260        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1261        done offline. A good approximation of the pressure load anomaly is
1262        necessary to avoid large initial adjustment processes underneath
1263        deep-reaching shelfice.
1264      - small fix in ISOMIP shelfice_thermodynamics
1265      - add more sophisticated thermodynamics of Hellmer (1989), this is
1266        now the default
1267      - give a few constants more intuitive names
1268    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1269      if bulk formulae are used in long integration (especially EmPmR). Turn
1270      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1271      if balancePrintMean, the imbalance that is substracted is printed to
1272      STDOUT.
1273    o fix bug (typo) in obcs_apply_eta.F
1274    o add a new package shelfice which enables us to model the circulation
1275      underneath shelf-ice with draughts of hundreds of meters.
1276     - works
1277     - to do: + include improved thermodynamics
1278              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1279                instead of new field kTopC
1280              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1281                instead of new field R_shelfIce and new code in ini_depth.F
1282                and ini_mask_etc.F?
1283              + adjust vertical mixing schemes?
1284    o seaice pkg:
1285     - add a cpp-flag to include a simple formula for a salinity dependent
1286       freezing point of sea water at the surface
1287     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1288       meridional stresses are now different (and hopefully correct)
1289    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1290       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1291       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1292    o pkg/diagnostics: add options and parameters for regional-statistics
1293       diagnostics ; define regions by reading a region-mask from a file
1294       (might add other options later)
1295    o pkg/bulk_force:
1296     - add option and parameters to use AIM surface-flux formulae.
1297     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1298       others forcing fields (defined in PARM05, parameter file "data") are loaded
1299       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1300     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1301     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1302     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1303       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1304     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1305    
1306    checkpoint58
1307    o add "--embed-source" option to genmake2 which, when the supporting
1308      tools can be compiled (as determined by genmake2) will turn on the
1309      embed_files package which then embeds the entire MITgcm source code
1310      (*.[fFhc] + Makefile) used for the build within the executable
1311      - requested by CNH but off by default
1312      - adds a paltry <9MB to the mitgcmuv executable in most cases
1313      - only writes the output when useEMBEDSRC in eedata is true
1314    o clean up 3-dim. relaxation codes:
1315      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1316      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1317      * Thanks to Tom Haine for testing!
1318    
1319    checkpoint57z_post
1320    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1321      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1322    o fix the pickup behavior for obcs in combination with ptracers
1323    o fix a bug in ptracers_external_fields_load
1324    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1325      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1326    o transfered surface NH pressure to eta field (if exactConserv).
1327    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1328         and update lab_sea output.txt file.
1329    o completing 3-dim. relaxation code: additional term
1330         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1331      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1332      * At compile time, in "EXF_OPTIONS.h" set
1333          #define  ALLOW_CLIMTEMP_RELAXATION
1334          #define  ALLOW_CLIMSALT_RELAXATION
1335      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1336          tauThetaClimRelax3Dim = 15552000.0,
1337          tauSaltClimRelax3Dim  = 15552000.0,
1338      * 3 cases:
1339          1) Use a constant-in-time 3-dim. field
1340          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1341          3) Real-time relax. to time-evolving prescribed field
1342    o Adding Laplacian-type smoothness constraint on
1343      initial and boundary (forcing) controls (ic, bc)
1344      * enable at compile-time via
1345        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1346      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1347      * Absolute scale somewhat unclear so far
1348      * no area weighting was included since no other cost term does so far
1349    
1350    checkpoint57y_post
1351    First step for a NLFS adjoint
1352    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1353    o new init. routines for calc_r_star, calc_surf_dr
1354    o still need to deal with ini_masks_etc
1355    o testreport seemed happy
1356    checkpoint57y_pre
1357    
1358    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1359    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1360    o add new offset feature to offline pkg (plus minor cleanup)
1361    o cfc fixes for final year of integration
1362    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1363      be in GCHEM_OPTIONS).
1364    
1365    checkpoint57x_post
1366    o fix testreport Pb in multiple test experiment.
1367    o cleanup our namelist syntax in verification:
1368      - make it more F95 standards compliant (some work still needed)
1369      - allows the vast majority of our tests to work with gfortran
1370    o Non-Hydrostatic:
1371     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1372     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1373    o Allow to apply AB on T,S rather than on AB(gT,gS):
1374     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1375     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1376       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1377     - need a "clever" read_pickup to restart from the other AB formulation
1378    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1379    o remove some unused variables (reduces number of compiler warnings)
1380    o adjoint
1381      * Disable useVariableViscosity for adjoint for time being
1382        (there are a number of extensive recomputations)
1383      * Initialize certain variables needed for adjoint
1384    
1385    checkpoint57w_post
1386    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1387                 fix the singleCpuIO RS version of MDSWRITEFIELD
1388       and add a WARNING if using globalFiles=T with multi-processors.
1389    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1390      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1391    o tracer advection scheme:
1392      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1393       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1394       was not very convenient).
1395      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1396       (further tests needed for the implicit DST & Flux-Limiter schemes).
1397    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1398      and sRef for convenience, handy, when you want to initialize
1399      ptracers in a large domain with a constant non-zero value. Also,
1400      untangle ptracers_init.F a little.
1401

1403    o change dome exp. to use variable viscosity in side-drag terms.
1404    o remove all the files from the cfc_offline test since they are now
1405      incorporated into tutorial_cfc_offline which has been producing
1406      identical results for a few days of testing
1407    o add new parameter: sideDragFactor to enable half-slip-side BC
1408      and change side-drag S/R to use viscosity from mom_calc_visc
1409      (can switch back by setting sideDragFactor=0.); affects results at
1410      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1411       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1412    o vorticity & strain are now computed without masking, to account for
1413      no-slip-side BC in variable viscosity calculation ; mask is applied
1414      anyway later on, before computing advection/coriolis terms.
1415    o modify exp4 to test new obcs support for reading from external files
1416      and for passive tracers
1417    o fix behavior of ptracers_monitor when monitor output is written to a
1418      netcdf-file; still not independent of monitor.F (writes in the same
1419      file).
1420    o change default value of tRef (put a uniform, meaningful value for ocean
1421      & atmos) and initialize sRef (was missing, as Martin mentioned).
1422    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1423      to be proportional to enstrophy dissipation length.  Thus,
1424       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1425      This is now consistent with Smagorinsky and with the manual.
1426    
1427    checkpoint57u_post
1428    o OBCS and PTRACERS: add open boundary support for passive tracers
1429      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1430        OB-values from file; this is not different from the way theta and salinity
1431        are treated
1432      - however, Orlanski-radiation conditions are not supported, and the model
1433        will stop if you use pTracers and Orlanski at the same time.
1434      - beefed up the rountine obcs_external_fields_load: now only those open
1435        boundary values are overwritten with values from files for which there
1436        are really files, otherwise the OB-fields remain untouched. This makes
1437        it possible to use different OBs at different ends of the domain (as
1438        with EXF)
1439    o reduce number of exch calls in shap_filt (s2).
1440    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1441      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1442    
1443    checkpoint57t_post
1444    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1445    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1446      same truncation, independent of the face number: affects affects several
1447      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1448    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1449      note that biharmonic viscosity + no-slip was not tested in any experiment.
1450    o fix bug in non-linear free-surf side-drag ; generate new output for
1451      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1452    o make mnc honor the writeBinaryPrec flag for most kinds of output
1453    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1454    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1455      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1456    o add brackets in multi-terms sum to get same truncation, independent of
1457      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1458      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1459    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1460      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1461      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1462      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1463      Suggested values of viscosity parameters found in mom_calc_visc.
1464      Many new viscosity diagnostics available.
1465    
1466    checkpoint57s_post
1467    o Add clearing-house for viscosity calculations, mom_calc_visc and
1468      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1469      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1470      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1471      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1472      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1473      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1474      ViscAhStrain and viscAhTension are now retired.
1475    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1476    o In response to JMC's bug report, genmake2 now ignores any soft-links
1477      that it finds in the *current* directory when searching for files.
1478      Soft-links found in any other source directories will still work as
1479      they did before.
1480    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1481      a C routine to unlimit the stack size
1482    o mnc-ify pkg/aim snapshot vars
1483    o mnc-ify pkg/land as requested by Daniel
1484    o various changes to mnc including:
1485      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1486      - output can now be grouped so that all files within a group
1487          change the ITER portion of their names in lock-step together
1488      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1489          and works with both EXCH1 and EXCH2 (but needs more testing)
1490      - writing works for all verification test cases w/ g77 on Linux
1491    
1492    checkpoint57r_post
1493    o make MNC variable initialization happen earlier
1494    o add diagnostics for (almost) each term of the momentum Eq.
1495    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1496    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1497    o remove MINIMAL_TAVE_OUTPUT option ;
1498      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1499    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1500      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1501    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1502    o add time-dependent SST, SSS control
1503    o cost terms in ecco/ modularized (new cost_generic.F)
1504    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1505    o new infrastructure for seaice model vs. obs misfits in seaice/
1506      * driver from the_main_loop.F is seaice_cost_driver.F
1507      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1508      * gradient check in Exp. 6a of natl_box_adjoint/
1509    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1510      (see README file)
1511    
1512    checkpoint57q_post
1513    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1514    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1515      - bug was reported by Jean-Michel and Ian Fenty
1516    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1517      update exp. cpl_aim+ocn output.
1518    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1519      Needed for high-res. runs with large global files
1520      to be able to limit tapelev size
1521    o Changed some tests for adjoint:
1522      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1523      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1524      * global_ocean.90x40x15/ back to default 3-level checkpointing
1525    o Modifications to enable scripted COMMON to MODULE conversion
1526      * verification/OpenAD/code/ has necessary scripts and description;
1527      * converts, compiles and runs successfully;
1528    
1529    checkpoint57p_post
1530    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1531    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1532      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1533    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1534    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1535      (was already the case for dissipation with mom_vecinv,
1536       and also the case for grad.PhiHyd when staggered-timeStep)
1537      This will allow to put dissipation out-off the AB time-stepping.
1538     Unfortunately, affects truncation error. Update output of exp. that "fails"
1539      (cg2d matching number) and leave the others for later: front_relax(10),
1540      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1541      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1542    
1543    checkpoint57o_post
1544    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1545      (2) its ready to be documented during the 20050801 DocFest
1546    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1547      for ideal_2D_oce and lab_sea on linux_ia32_g77
1548    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1549      in global1x1_tot/code_seaice_adj to access indices 32, 33
1550      (worth another tag)
1551    
1552    checkpoint57n_post
1553    o adding precip control xx_precip 32
1554    o adding swflux control xx_swflux 33
1555    o Replacing 10 forcing penalty cost routines by 1 generic.
1556    o Implementing partitioning in time-mean and variable adjustment
1557      for atmos. state.
1558    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1559  o in natl_box_adjoint:  o in natl_box_adjoint:
1560    * updated: results_bulk/    * updated exp 1 to 10
1561    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1562    o updated global1x1/*_seaice_adj/
1563      to incorporate latest changes
1564    o enable useSingleCpuIO for mdsio vector routines
1565      (applies in particular to tapelev I/O)
1566    o removed inefficient K-loop in all active_file*control*.F
1567    
1568  checkpoint57m_post  checkpoint57m_post
1569  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)
