4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
8    o pkg/grdchk: Add gradient check to etan0 perturbations.
9    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
10    o pkg/autodiff: more flexibility in zeroadj.
11      model/src: modifying do_oceanic_phys.F accordingly.
12    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
13    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
14      special setup of gmredi for which the adjoint is stable
15      enough for parameter optimization.
16    o bridging the gap between eddy stress and GM.
17      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
18          along with a change in CPP option (now ALLOW_EDDYPSI).
19      -> when using GM w/ GM_AdvForm:
20          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
21          is applied either in the tracer Eq. or in momentum Eq.
22          depending on data.gmredi (intro. GM_InMomAsStress).
23      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
24      The key modifications are in model/src/taueddy_external_forcing.F
25      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
26    
27    checkpoint59r
28    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
29      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
30      fix option to read coriolis(@ cell-corner) from files with CS-grid.
31    o pkg/mnc: add some attributes to standard 1D-coordinate variables
32    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
33      mass points, when using mnc for output
34      - add runtime parameter (missing_value, missing_value_int) to override
35        default (which is the value of getcon('UNDEF'))
36    o pkg/mnc: prepare mnc for the actual use of missing values with the
37      diagnostics package: small fix in mnc_cw_readwrite.template and more
38      initialisation of never used fields
39      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
40      versions
41    o pkg/thsice/thsice_ini_vars.F added default initial values so that
42      thermodynamics sea ice solver does not blow up when some initial fields
43      are missing.
44    o move from external_forcing_surf.F to ini_forcing.F
45      the p-coord. hack consisting in using pLoad to set phi0surf ;
46      update output of tutorial_global_oce_in_p (affected @ truncation level).
47    o Freshen up a bit hs94.1x64x5, notably:
48      remove rotationPeriod and tRef=5*0. (adjoint only), and add
49      exactConserv=.TRUE.
50    o pkg/generic_advdiff:
51      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
52      applies to files where Temperature & Salinity 2nd Order moments are used.
53    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
54      this uses a dynamically allocated internal state data structure
55      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
56      and requires a fortran 90 compiler
57    
58    checkpoint59q
59    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
60       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
61    o Refresh tutorial_global_oce_biogeo, notably:
62      - change bathymetry (put back seamounts in ACC, use hFacs)
63      - change EOS (POLY3 --> JMD95Z)
64      - use Bryan-Lewis vertical diffusivity
65      - use multidimensional advection
66      - remove old virtual virtual in dic pkg, now done through ptracer pkg
67      - change a couple of parameters in dic pkg
68    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
69    o pkg/obcs: change default to OBCSfixTopo = .true.,
70      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
71      - replace "debugMode" with "debugLevel .GE. debLevB"
72    o implementation of TAF directives for gchem,cfc,dic
73    o remove "exp5" (replaced by tutorial_deep_convection).
74    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
75      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
76      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
77      --> changes results in exp4, seaice_obcs
78    o tutorial_deep_convection :
79      update the set-up and increase resolution and domain size ; start
80      from pseudo initial conditions = output at t=120mn in order to see
81      something happening when running testreport.
82    o pkg/seaice: add os7mp as an advection scheme
83                  add check for advection schemes
84                  add a flag for restoring T and S underneath sea ice
85    o pkg/my82: add netcdf-support and diagnostics
86    o thsice pkg:
87      - Now hsMax limits snow height by turning it into ice following
88        flooding scheme (and now conserving energy)
89      - Slight rewriting of the formula in thsice_calc_thick.F
90      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
91      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
92    
93    checkpoint59p
94    o gchem / dic / cfc :
95      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
96      - add new parameter files: "data.dic" & "data.cfc" ;
97      - various re-arrangement in initialisation & header file ;
98      - fix tutorial_global_oce_biogeo for multi-threaded test.
99    o pkg/dic: test for "pickup_dic" file when restarting ;
100      if no pickup-file, can restart with a re-initialised pH (same as it did
101      before) providing pickupStrictlyMatch is set to False.
102    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
103      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
104    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
105      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
106    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
107     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
108       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
109    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
110       scheme to use for vorticty-term ;
111     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
112       (with default selectVortScheme, return to original discretisation)
113     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
114    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
115    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
116      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
117      also fix diagnostics VISCAHW & VISCA4W.
118    
119    checkpoint59o
120    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
121    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
122      move a few statemens out the main loop into separate loops
123    o pkg/shelfice:
124      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
125        (kg/m^2/s), does not break tests, because in verification/isomip,
126        rhoConstFresh=rhoConst (by accident)
127      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
128      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
129        new file model/src/seawater.F, so that they are available for all pkgs.
130      - convert potential temperature into in-situ temperature. This changes the
131        isomip tests => update tests
132    o add a flag writePickupAtEnd (default=true) to be able to suppress
133      writing a pickup at the last timestep
134    o tools/mpack-1.6 :
135      - disable automake (not working) and autoconf (not needed).
136      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
137        also cleaner with much less compilation warnings.
138    o pkg/profiles:
139      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
140      (for "less than 32 characters name" compiler requirement)
141    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
142      conditions that have a different sampling frequency than S/T/U/V obcs
143    o pkg/diagnostics (stats-diags):
144      - fix global Min/Max in case 1 processor get only empty tiles
145    o genmake2: replace (4 times)
146         make genmake_tc_1.o >> genmake_warnings 2>&1
147      with
148         COMM="$CC $CFLAGS -c genmake_tc_1.c"
149         echo $COMM >> genmake_warnings
150         $COMM >> genmake_warnings 2>&1
151      to make genmake2 always see the value of CC as specified in the optfile.
152    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
153      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
154      - modify verification advect_cs test to test SOM-advection on CS-grid.
155    o pkg/ctrl:
156      - Rewrite of ctrl_map_ini_ecco.F,
157        introducing a generic routine (ctrl_map_ini_gen.F).
158      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
159    
160    checkpoint59n
161    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
162      number in dedicate array "hdiag":
163      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
164        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
165      - many small changes (integer format) for large number of diagnostics
166      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
167        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
168    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
169      usingSphericalGrid, this allows to define the rotated grid coordinates
170      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
171      geographical coordinates according to the inverse of the rotation defined
172      by the Euler angles, so that Coriolis parameter and online-interpolation by
173      exf works with the geographical coordinates on XC/YC/XG/YG.
174      Naturally, this feature does not work with all packages, so some
175      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
176      profiles), because there the coordinates are assumed to be regular
177      spherical grid coordinates.
178    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
179      - introduce isopycnal diffusion coefficient control.
180    o tools/adjoint_options:
181      - additional control vector components.
182    o pkg/mnc: have mnc create marginally meaning full coordinate variables
183      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
184    o pkg/mypackage:
185      - add example of read/write pickup for state-var ;
186      - add entry points to the main code for state-vars diags & write-pickup.
187    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
188      transitions for useExfYearlyFields
189      - add new subroutine that determines the file to read from for
190        use*YearlyFields = .TRUE. and .FALSE.
191      - add a verification experiment to global_with_exf that tests
192        useExfYearlyFields with USE_EXF_INTERPOLATION defined
193    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
194      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
195      subroutines (which could be generated from a template, because they are
196      almost identical), for now they are included in obcs_prescribe_read.F for
197      simplicity
198    o pkg/exf:
199      - add a little more diagnostic to exf_interp_read (in analogy to
200        mds_read_field, can be turned off with debugLevel < debugLevA=1)
201      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
202        ugly but fast by unrolling short inner loops, inserting a unroll=8
203        directive in routine lagran, and splitting a loop and making do while the
204        outermost loop (the latter requires the intoduction of index arrays)
205    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
206    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
207      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
208    o verification/seaice_obcs: updated for restart test and latest options
209    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
210      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
211      for now this is only available for the C-grid code and also within
212      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
213    
214    checkpoint59m
215    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
216      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
217    o gad_som : fix flux output (& diagnostics) to have same units as other  
218      advection scheme fluxes (was previously multiplied by deltaT).  
219    o added verification/seaice_obcs both to test seaice open boundaries
220      and to provide an example matlab scrpt for generating them
221    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
222    o pkg/salt_plume: clean up salt_plume_frac.F to
223      remove redundancy in PlumeMethod 1 and 4
224    o pkg/kpp: added saltplume diagnostics
225    o pkg/obcs and pkg/seaice:
226      - do not set uice and vice to zero when OB*icefile are unspecified
227      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
228      - moved seaice tracer obcs after call to seaice_growth
229    o pkg/salt_plume: added various options for salt plume depth
230      criterion and for vertical distribution of the salt
231    
232    checkpoint59l
233    o pkg/ptracers: new version of ptracers pickup:
234      read meta file and write only fields which are needed to restart.
235      ( same logic as main pickup file ; also using pickupStrictlyMatch )
236    o pkg/seaice:
237      - add timescale for melting due to warm mixed layer as a means of
238        setting SEAICE_availHeatFrac more conveniently
239      - add a CPP-flag/runtime parameter check for flooding algorithm
240      - reformulated availHeat in seaice_growth.F to be independent of AREA
241    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
242      unit changes
243    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
244    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
245      SX vector computer.
246    o pkg/seaice:
247      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
248        seaice forcing fields can now be read only through pkg/exf
249      - removed some unused halos
250    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
251    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
252      or U/VICE from U/VWIND before computing U/VSTRESS
253    
254    checkpoint59k
255    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
256      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
257    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
258      all experiments pass when compile with un-initialised var. checking option.
259    o added pkg/salt_plume
260    o script to test restart (for now, in MITgcm_contrib/jmc_script)
261    o pkg/seaice: new read/write pickup version.
262      read meta file and write only fields which are needed to restart.
263      ( same logic as main pickup file ; also using pickupStrictlyMatch )
264    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
265    o lab_sea.hb87: modify the domain & update output.hb87.txt :
266      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
267      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
268      process. Fixed here by closing the domain at the Northern boundary.
269    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
270    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
271      a set of consecutive levels in/from a 3-D array.
272    o pkg/ptracers:
273      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
274      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
275    
276    checkpoint59j
277    o in pkgs: dic, obcs, offline, rbcs:
278      standard way to compute coeff. for time interpolation between 2 time reccords
279      which retains full precision (& make results less dependent on compiler).
280      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
281    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
282      packages instead of reading ice cover and wind speed separately
283    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
284     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
285      to allow to compile customized code before the update)
286    o cleaning-up:
287      - fix CPP instruction syntax in pkg/obcs
288      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
289        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
290      - fix some threads issue in IO parts.
291    o pkg/dic:
292      - add tons of "_d 0" (--> much better testreports !)
293       and then update outputs of tutorial_global_oce_biogeo
294    o pkg/mom_fluxform:
295      add a special version of momentum advection intended to conserve momentum
296      next to a bathymetry step or a coastline edge. (default = off = #undef)
297    o new read/write pickup version:
298      - for now, only implemented for main (mdsio) pickup file.
299      - write out only what is needed to restart; merge pickup_nh , pickup_ph
300        and main pickup together.
301      - read meta file; read only what is needed to restart; stop if a field
302        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
303        if it make sense (even if the restart is not perfect).
304      - if no meta file, assume that pickup to read corresponds exactly to
305        a pickup that would currently be written.
306      - read pickup written in the old format (until checkpoint59i) if it
307        recognizes an old meta file (no field-list).
308      - add a meta file in exp. which starts from a pickup: 2 cases:
309        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
310         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
311        b) a meta file describing the content of the associated pickup file
312         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
313    o pkg/mdsio & pkg/rw:
314      - new routine to read a meta file ; new set of routine to read
315        Multiple-fields file (with meta file).
316    o added open boundary conditions capability for seaice
317        HSNOW, HSALT, UICE, and VICE
318    
319    checkpoint59i
320    o adjoint:
321      * fix multiDimAdvection adjoint
322        (partial recomputation problem by TAF for fVerT(:,:,kDown)
323        and comlev1 size definition (maxpass vs. max. number of tracers)
324      * verification/global_ocean.90x45x15 adjoint now tests
325        NLFS and multiDimAdvection using DST3 (=30)
326      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
327    o pkg/kpp: add "_d 0" to real constant (if missing);
328      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
329      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
330    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
331      for internal parameters related to restart process (formerly from PARAMS.h)
332      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
333    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
334      as argument. (only atm2d & obcs write_pickup have not yet been updated)
335    o pkg/monitor:
336      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
337      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
338      - account for deep Atmosphere factor and density factor (anelastic)
339    o added open boundary conditions capability for seaice HEFF and AREA
340    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
341      thermodynamics
342      - requires a little reorganization, which affects the testreport results
343        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
344        so that now the conservative form is tested
345      - add a few comments
346    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
347    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
348    o add new diagnostics to seaice: advective, diffusive fluxes (only for
349      multidim-advection, for scheme 2 they are not filled) and transports,
350      thermodynamic growth rates
351    o change units of EmPmR (inside the code, + within coupling interface)
352      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
353      Affects results @ truncation level (cg2d match) and update output of
354       experiments: lab_sea(6), global_ocean.90x40x15(10),
355      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
356      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
357      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
358      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
359    
360    checkpoint59h
361    o pkg/exf:
362      - improve vectorization by moving if-statement out of loops in
363        exf_mapfields, exf_radiation
364      - exf_bulkformulae.F: introduce 2D fields and vectorize code
365    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
366    o testreport:
367      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
368        monitor & update offline_exf_seaice exp. output.
369      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
370    o pkg/seaice:
371      - bug fix in the evp solver: boundary conditions were affected be
372        masking of zMax/zMin (changes results)
373      - minor bug fix in boundary conditions in seaice_calc_strainrates
374        (changes results for no_slip)
375      - seaice_lsr.F: make interpolation of eta dependent on boundaries
376      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
377      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
378        stress formulation and no-slip boundary conditions
379    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
380      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
381    o pkg/seaice: a first HSALT time stepping equation has been checked in
382    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
383      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
384      without requiring DO-IF statements
385    o pkg/thsice:
386      use continuous power-law function for partition of energy between lateral
387      melting/freezing and thinning/thickening ; old code using step function
388      still available with #undef THSICE_FRACEN_POWERLAW
389      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
390    o testreport: change AD testing : check against results/output_adm.txt
391      using same scripts as for forward test.
392    
393    checkpoint59g
394    o adjoint testing: in preparation for changing testreport:
395      - output format: cost and grad written on separated lines
396      - ad output results in directory "results" (instead of "results_ad")
397    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
398    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
399    o pkg/ecco: allow user defined cost function contributions
400    o testreport:
401      Allow to choose (per experiment) the list of tested output variables
402       and the main variable (used to issue a pass/FAIL ) ;
403      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
404      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
405      Also modify printing of summary:
406       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
407       b) echo the list of tested variables in the individual summary.txt of
408          each experiment.
409    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
410      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
411      (but still depend on the tile decompostion of the domain).
412    o pkg/seaice: change a discretization detail to make the B-grid code
413      "more symmetric". This change is likely to remove all "ridges/leads" that
414      where quasi-aligned with the grid in B-grid solutions. It may also be
415      the solution to the stress coupling issues with the B-grid.
416    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
417      remove .cvsignore from input dir. (since testreport no longer run here).
418    o pkg/thsice:
419     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
420     - fix reshaping of sea-ice just after advection:
421       melt all the ice only if ice-volume is too small.
422     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
423       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
424     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
425    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
426      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
427    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
428      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
429      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
430      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
431      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
432      -> update output.txt
433    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
434     this affects truncation error: -> update output.txt of exp:
435      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
436      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
437    
438    checkpoint59f
439    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
440    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
441      a bounded range (in forward mode)
442    o pkg/ecco, ctrl, autodiff and mom_common:
443     internal parameter controls, completements of implementations
444    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
445    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
446      (not seem any difference in testing results).
447    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
448       at face corners.
449    o pkg/generic_advdiff:
450     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
451      loop range indices for computing vertical advection tendency
452      and do the calculation in the interior only (no overlap) ;
453      for now, only implemented for SOM advection (to save CPU time).
454     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
455    o exch2 adjoint
456      First set of changes:
457      - add exch2 hand-written adjoint templates
458      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
459        This will require cleanup in pkg/autodiff/*.F
460        (changed routines currently kept separate in verif. code/)
461      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
462        that used to hide exch2 or cubed-sphere specific code
463        (commented via 'cph-exch2')
464    o pkg/seaice
465      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
466    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
467       output of global_ocean.cs32x15.thsice .
468    
469    checkpoint59e
470    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
471      for B-grid vector (not yet tested) and C-grid vector (<- only used
472      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
473    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
474      (#ifdef ALLOW_SALT_PLUME)
475    o gather_2d/scatter_2d: removed halo regions
476    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
477      scheme and the corresponding test case (under front_relax dir). For now,
478      only available with Skew-flux form and not yet tested in realistic set-up.
479      adjoint: store directives updated, but gradient checks deteriorated,
480      so maybe GM/Redi adjoint is now broken.
481    o seaice adjoint
482      * add AREA, HEFF, HSNOW as control variable
483        (should not change lab_sea results)
484      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
485    o pkg/seaice:
486      * added computation of saltFlux in seaice_growth;
487        For time being, sea ice salinity is assumed constant
488        contribution of snow flooding to freshening of sea ice is neglected.
489        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
490        defaults to 0.0 in order to maintain backward compatibility.
491        Typical values for SEAICE_salinity are 4 to 10 g/kg.
492      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
493      * added SEAICE_availHeatFrac, which specifies fraction of surface level
494        heat content used to melt or grow ice
495      * commented out cap of HICE: it helps keep ice thinner
496      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
497      * applied OBCS T/S mask to HEFFM sea ice mask
498    
499    checkpoint59d
500    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
501     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
502     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
503    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
504     and change default value of parameter "GM_Small_Number";
505     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
506       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
507       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
508    o pkg/ecco: cost function when applying pkg/smooth to controls
509    o pkg/ctrl: add forcingPrecond run time parameter
510    o pkg/seaice:
511     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
512     - fix bug in metric terms of u-equation in LSR solver (implicit part),
513       changes verification/lab_sea
514     - rearrange implicit part of u-equation in LSR solver to make it easier to
515       read, understand, and debug. This causes changes at the truncation level.
516     - fix (serious) bug in the boundary conditions (sign error in the implicit
517       part) of the LSR solver. Changes all LSR results.
518     - fixed problem with HSNOW initialization to avoid thick snow when AREA
519       is initilized with small values - does not change lab_sea results.
520     - added HsnowFile initialization capability
521    o pkg/smooth: addition to model/src and pkg/ctrl so allow
522     initialization of pkg/smooth and application to control vector
523    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
524    o dependencies: pkg/profiles requires pkg/cal
525    o pkg/profiles:
526     - added option ALLOW_PROFILES_GENERICGRID
527         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
528         that interpolation information (grid points and coefficients) is provided
529         within the netcdf input files.
530         -> sample matlab scripts can be found in MITgcm_contrib/gael
531         that allow you to prepare netcdf input files.
532     - also modified: cleaner include statements, cleaner error print statements,
533       cleaner stops when error, and more tests of the netcdf input files consistency.
534    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
535    o pkg/seaice:
536     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
537       requires a new routine: seaice_diagnostics_fill.F
538     - make sure that seaice does not move if not forced (pressure replacement
539       method, Hibler and Ip, 1995), changes results
540     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
541     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
542       It is turned off by default (=-1.), because it changes the results.
543     - make it possible to read AREA from a file, too.
544    
545    checkpoint59c
546    o add S/R and diagnostics for oceanic mixed-layer depth
547    o move GMRedi call after all vertical mixing schemes (including KPP)
548    o pkg/thsice:
549     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
550      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
551    o pkg/obcs:
552     - bug fix for balance code
553    o pkg/seaice:
554      - allow values of SEAICE_elasticParm > 1
555      - add new parameter SEAICE_evpTauRelax as an alternative
556        to SEAICE_elasticParm
557      - make lsr boundary conditions free slip (by default), changes result
558      - add code for no slip boundary conditions for lsr
559      - set minimum of zeta to zero (and not 4e8) (changes results)
560      - add a cap on AREA after advecting AREA if seaice_growth is not called
561    o change calculation of Visbeck K:
562      - no longer depend on tapering scheme; instead, compute slope (limited
563        by GM_maxSlope). this is equivalent to what was comuted before with
564        clipping or linear tappering.
565      - fix vertical averaging (wrong by 1/2 level)
566      - leave the old version (but will not be maintained) within
567        #ifdef OLD_VISBECK_CALC / #endif
568      - update output of exp. ideal_2D_oce
569    o change error catch in calc_r_star to improve vectorization
570    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
571      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
572    o adjoint:
573      Re-organized adjoint checkpointing according to Matt Mazloff
574      (but with modifs/completions/cleanups)
575      Storing is now bundled into large arrays to optimized I/O
576      (and second step in cleanup of the_main_loop)
577    
578    checkpoint59b
579    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
580      - export/import (between ocean & coupler) fields needed for ocean DIC.
581    o pkg/seaice:
582      - get rid of three more exchanges seaice_calc_viscosities (required
583        different loop boundaries in seaice_lsr and seaice_ocean_stress)
584      - bug fix in seaice_ocean_stress (update of lab_sea required)
585      - reduce loop boundaries to necessary minimum also in seaice_evp
586      - go back to the old way of computing deltaC/Z as the adjoint likes that
587        better
588    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
589      passive tracer to an Age Tracer) + update output.txt
590    o pkg/exf:
591      - implement A-grid / C-grid selection for wind-stress input files.
592      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
593      for now, in exf_bulk_largeyeager04.F only :
594      - change implementation for case where windspeed + 2. components wind-stress
595        are read-in. AND use rhoConstFresh to convert evap.
596    o pkg/seaice:
597      - use correct EXCH_UV for wind-forcing (on A-grid).
598      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
599        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
600    o pkg/exf:
601      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
602      EXF_INTERPOLATION:
603      - merge global_with_exf/code version of exf_interp_read.F
604        to the main code ;
605      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
606        reading the file ; Important: This options needs to be defined to recover
607        previous code.
608        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
609      - no longer loose real*8 precision along the way when using exf_iprec=64.
610    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
611      - change discretisation of evp-solver in order to avoid another exchange
612        (changes lab_sea) and clean up a little
613      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
614        help the adjoint (this also changes the results slightly)
615      - add a few "_d 0" where they had been missing in seaice_evp.F
616      - cleaning up: remove unused seaice_calc_rhs.F
617    o pkg/exf: some cleaning-up:
618      - change various "constants" into runtime parameters
619      - cleaned-up Large&Yeager04 routine which should eventually
620        replace exf_bulkformulae.F (changed names of S/R and CPP)
621        and merged various ALLOW_ATM_WIND options
622     only used with thsice pkg (in thsice_get_exf.F):
623      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
624        which are used when useStabilityFct_overIce=TRUE (= the default)
625      - change default values of ice & snow emissivity and scale downward LW
626        by ice & snow emissivity.
627    o pkg/thsice:
628     fix few little problems, in thsice_calc_thickn.F:
629      - growth vertically (and not laterally) if iceFrac == iceMaskMax
630      - melt only laterally if hIce < hThinIce (as the comments say)
631      and in thsice_extend.F:
632      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
633      - start to form ice as soon as the minimum ice-volume is reachable.
634     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
635      and cpl_aim+ocn
636    o pkg/kpp
637     - move computation of surface related input fields to KPP into a new
638       subroutine kpp_forcing_surf.F
639     - remove wrong (within bi,bj loops) EXCH calls.
640     - little cleaning (add argument myThid in last position, cvs header ...)
641     - for now, fix conservation problem by exchanging KPPviscAz (may not
642       be the best fix)
643    o pkg/seaice
644     - check for inconsistent evp parameter/cpp-flag combination
645     - remove leftover errIO flat for obsolete name list error handling
646    o OpenAD
647     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
648    
649    checkpoint59a
650    o pkg/seaice: some parameter clarifications and a little bit of clean up
651    o pkg/thsice: rename run-time parameters:
652       himin       -> hIceMin
653       himin0      -> hThinIce
654       hihig       -> hThickIce
655       i0          -> i0swFrac
656       transCoef   -> bMeltCoef
657       frac_energy -> fracMelting
658      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
659       with default values (for now) that do not change the results.
660      remove old version of thsice vars advection in pkg/seaice.
661    o in FFIELDS.h:
662      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
663      - make pLoad & sIceLoad always available (but still only used if
664         ATMOSPHERIC_LOADING is #define).
665    o pkg/kpp: replaced _KPP_RL with _RL
666    o bug fixes for vertical diffusivity computations when both KPP and
667        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
668        are no longer updating the vertical diffusivity array
669        (passed as argument) but are (re-) setting those arrays.
670    o pkg/seaice: fix bug in evp solver, while doing that
671      - change (improve?) discretization of stress computations for both
672        cgrid-lsr and evp solver
673      - add a new routine to compute strain rates
674      - the above changes lab_sea results
675      - add no slip conditions for evp solver (off by default), lsr-version
676        may follow
677      - fix exchange for shear at Z-points (does not change lab_sea)
678      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
679        (to force the user to pick a time step since there is not "safe" way
680        of choosing it)
681      - add principal stress diagnostics
682      - rearrange fields for evp a little to avoid having to call a: too many
683        exchanges and b: exchanges for stress trensor components which we do
684        not have.
685      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
686        of evp, complete rewrite for lsr case (latter is does not yet work
687        in all cases)
688    o pkg/kpp: add code to have mixing in shelf ice caverns
689      - add myThid to all kpp routines (long overdue)
690    
691    checkpoint59
692    o pkg/exf:
693      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
694        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
695      - move exf header files from lower_case.h to UPPER_CASE.h ;
696        add missing cvs Header & Name
697      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
698      - add namelist param. selectStressGridPosition, exf_monFreq
699      - retire many _CLIM routines, and remove data.exf_clim
700        + params moved to data.exf
701        + climsst, climsss now handled by exf_set_gen, i.e.
702          climss?period=0 refers to constant field,
703          climss?period=-12 to monthly forcing
704      - split up namelists in data.exf
705    o pkg/seaice:
706      - remove seaice_exch and seaice_exch_uv
707      - remove superfluous exchange of theta
708      - add myThid to seaice_budget_ocean/ice
709      - add new interface for atmospheric wind forcing (C-grid only)
710        + new routine
711        + two new field (taux, tauy for stress over ice)
712        + removed one global field (DAIRN) for C-grid case only
713    o pkg/thsise
714      - 2nd set of modifs for thsice adjoint in conjunction with exf
715    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
716    
717    checkpoint58y_post
718    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
719      vertical diffusivity, similar to that in MOM4; turned on using
720      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
721      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
722    o Added capability for 3D specification of background vertical diffusion
723      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
724      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
725      "data" file that contains the 3D vertical diffusivity coefficients.
726    o ice dynamics (pkg/seaice) with thsice thermodynamics:
727      - add code within pkg thsice to advect & diffuse sea-ice fields
728      similar to (and will replace) what has been added in  seaice_advdiff.F,
729      but: - conserving Mass, Heat & Salt.
730           - better when using non-linear advection scheme (not yet fully tested)
731           - can also be used in atmospheric set-up (for now, only the diffusion).
732    
733    checkpoint58x_post
734    o IO option for global-file compact format:
735      - add options when generating topology (utils/exch2/matlab-topology-generator)
736      - add I/O capability (pkg/mdsio).
737      - adapt utils/matlab/rdmds.m to read this format.
738      for now long-line format not yet supported by pkg/mdsio (& exch2).
739    o shelfice: add a few diagnostics
740    
741    checkpoint58w_post
742    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
743      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
744      (and replace horiVertRatio in NH code).
745      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
746                         and tutorial_plume_on_slope (sensitive to truncation)
747    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
748      directly to drive seaice model (C-grid only)
749    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
750     - reintroduce computation of wind from stress,
751     - compute tau (in exf_bulkformulae.F) from windstress averaged to
752       mass points to avoid tau = 0
753     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
754    o rdmnc.m: make it work with "global" files created with gluemnc
755    o rdmnc.m : some improvements in dealing with singleton dimension
756      (tested on all testreport mnc output files).
757    o genmake2: disable pkg/profiles if netcdf test fails.
758    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
759    o move call to cal_readparms up to make calendar parameters/variable available
760      to all packages
761    
762    checkpoint58v_post
763    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
764      useDynP_inEos_Zc tested.
765    o pkg/exf: changes to properly interpolate/mask/scale initial fields
766    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
767      and portions thereof.  See read_cs.txt for description and examples.
768    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
769      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
770      following the great-circle arc between those 2 points.
771    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
772      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
773    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
774     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
775     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
776     - still needs work (not working with some options ; efficiency to improve)
777       and serious testing.
778     - use this scheme for temperature & salinity in 2 advection test exp.:
779       advect_xy & advect_xz, respectively.
780    
781    checkpoint58u_post
782    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
783    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
784    o testreport: add option "-skipdir" to skip some test.
785    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
786      momentum calculation.
787    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
788    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
789      remove checkpoint.F and the_correction_step.F (no longer used);
790      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
791    o add option (linFSConserveTr) to correct for tracer source/sink due to
792      Linear Free surface
793    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
794    o pkg/thsice: fix reading mnc-pickups
795    
796    checkpoint58t_post
797    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
798    o pkg/mdsio:
799     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
800       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
801       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
802     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
803     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
804       either MDS_READ_FIELD or MDS_WRITE_FIELD )
805     - new S/R (to replace MDSWRITEMETA), which allows to write more
806       informations (variable names, time ...) to meta files.
807     - modify rdmds.m to give back the meta file content.
808    o pkg/diagnostics: change vertical interpolation to be safer, and more
809       flexible (define p-levels to interpolate to in data.diagnostics);
810      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
811       diagnostic pointer.
812    o pkg/seaice: more cleaning up of seaice_growth, added many comments
813    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
814    o fix multi-category seaice:
815     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
816       SEAICE_MULTICATEGORY
817     - fix short wave heat flux
818    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
819       and allow to use EVP solver. Change forward lab_sea: test both EVP
820       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
821    o Initial check-in of lab_sea adjoint
822      (very similar to natl_box_adjoint/code_seaice)
823      * used C-grid and EVP solver
824      * used KPP, GM/Redi
825      * uses inAdExact=.TRUE.
826      * gradient checks fail for both ADM and TLM
827        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
828        f.d. gradients actually seem more problematic than ADM, TLM gradients;
829        issue is related to forward mismatch between g77 an ifort
830    o pkg/seaice: overhaul of thermodynamics
831     - growth.F and groatb.F are replaced by new routine seaice_growth.F
832     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
833     - move a few global fields out of SEAICE.h into seaice_growth.F and
834       make them 2D (FICE/QNETO/ ...)
835     - remove FO (it is the same as QNETO)
836     - introduce a few local fields to avoid modifying external fields such
837       as atemp, etc.
838    
839    checkpoint58s_post
840    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
841      changed exf_set_gen.F so that
842        genperiod=0 means input file is one time-constant field and
843        genperiod=-12 means input file contains 12 monthly means
844    o CG2D: use pre-computed solver main-diagonal (stored in common block);
845      this affects truncation error ; generate new output file for exp. which
846      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
847        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
848        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
849        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
850        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
851        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
852    o start implementation of deep-atmosphere and anelastic formulation
853    o verification: remove 2nd copy of input files and use script "prepare_run"
854      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
855    o mom_common/vecinv/fluxform: fix a few initialisation isssues
856    o profiles: fix for multithreaded case
857    
858    o diagnostics: rename few diags:
859      s/'PRESSURE'/'RCENTER '/g
860      s/'TICE    '/'oceFreez'/g
861      s/'TAUX    '/'oceTAUX '/g
862      s/'TAUY    '/'oceTAUY '/g
863      s/'SWFLUX  '/'oceQsw  '/g
864      s/DIFx/DFxE/g
865      s/DIFy/DFyE/g
866      and add few ocean-forcing diagnostics:
867      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
868    o modifications to pkg/seaice/growth.F and budget.F, which change results of
869      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
870      as actual snow thickness.  It now refers everywhere to effective snow
871      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
872    
873    checkpoint58r_post
874    o modifications to pkg/seaice/growth.F, which change results of
875      lab_sea experiment: fixes pertain to melting snow over open water, to
876      masking EVAP under sea ice, and to using the correct AREA variable for
877      computations of EVAP, PRECIP, HSNOW, and GHEFF
878    o add ability to read bathy, salt, and theta using MNC (off by def)
879    o add flooding algorithm and advection of HSNOW for pkg/seaice;
880      both are turned off by default and do no change any results
881    o seaice advection with pkg/thsice: a step toward the use of non-linear
882      advection scheme, but #ifdef or commented out for now (requires more EXCH).
883    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
884      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
885      in natl_box (affects results @ truncation level: update output.txt)
886    o multi-threading and IO:
887      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
888      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
889        (needed to work with SingleCpuIO): tested in all verif. exp.
890    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
891      affects the results (but none of the verification test uses this scheme).
892    o Adding some pkg/diagnostics capability to pkg/seaice
893      (will certainly be subject to changes)
894    o ctrl: adding new control variables:
895      lwflux, lwdown, evap, snowprecip, apressure, runoff
896    
897    checkpoint58q_post
898    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
899      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
900      high_res_cube configuration by 4% on Columbia.
901    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
902      add (in global_with_exf/code) a version of EXF_INTERP_READ without
903      dynamical allocation (seems to work in multi-threaded).
904    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
905      single CPU io) so that TAF does not have to see EESUPPORT.h
906    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
907    
908    checkpoint58p_post
909    o obcs: stop if obcs is used with useCDscheme = .true.
910    o shelfice:
911     - fix a sign error so that no slip at shelfice interface works
912     - remove stop for combination non-hydrostatic code and shelfice. That does
913       not mean, that the results are correct, but at least they are numerically
914       stable
915    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
916    o added adjoint exch routined for all exch*3d* routines
917      and updated flow directives
918    
919    checkpoint58o_post
920    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
921      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
922    o change controling S/R for writing pickup file (new S/R do_write_pickup)
923      and clean-up reading/writing of pickup files.
924    o fix local version of read/write pickup (NH part) in rotating_tank/code
925    o simplify EXCH interface:
926     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
927     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
928    o added the regrid package
929    o shelfice:
930     - add a simple boundary layer scheme to reduce noise
931     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
932    
933    checkpoint58n_post
934    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
935       local variable (not in common block).
936    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
937      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
938      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
939        to work with SingleCpuIO.
940    o add "_d 0" to real constant of pkg/cfc subroutines ;
941       update exp. cfc_exemple & tutorial_cfc_offline output files.
942    o multi-threading and IO:
943      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
944        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
945      - barrier before and after reading.
946      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
947      - avoid using MDS_WRITELOCAL for LAND pkg output.
948      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
949        common-block variables ; Allows multi-threading with master-thread IO.
950    o change default MAX_NO_THREADS from 32 to 4 ;
951      and stop cleanly when MAX_NO_THREADS is too small.
952    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
953    
954    checkpoint58m_post
955    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
956       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
957    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
958       keep global_ocean.90x40x15 (for AD testing) with former secondary test
959       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
960    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
961        add MITgcm_tutorials (= code + all the tutorials)
962    o ecco, option to compute cost for total ssh (mean+anom)
963    o consistent with addition of ptracer and ssh in pkg/profiles
964    o profiles: adding ptracer and ssh
965    o testreport: change multi-test output-file name
966      (from output.txt.{name} to output.{name}.txt)
967    o profiles: now ok for mutli-tiles case
968    o seaice: add 4 parameters for different advection schemes for area,
969      (effective) seaice thickness, enthalphy, and snow height. Their default
970      is the standard parameter SEAICEadvScheme
971    o calc_gw:
972     - add cosFacU in zonal viscous flux (harmonic.visc.).
973     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
974       of tutorial_plume_on_slope.
975    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
976    o calc_gw: true flux-form, account for horizontal grid spacing.
977      update rotating_tank results, but not plume_on_slope (affected at
978      truncation level, 11 digits).
979    
980    checkpoint58l_post
981    o calc_gw:
982     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
983     - remove side-drag for now (need to fix it); update plume_on_slope results.
984     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
985    o commit code to make SST/SSS weights spatially variable
986      (based on either variable in-situ or variable initial T/S weights)
987    o pkg/ecco:
988      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
989        now based on horizontally varying weights wthetaLev, wsaltLev
990      * cost_averagesflags now returns year indices in addition to day, month
991      * sflux balance is performed on annual basis
992        (sflxumm, sfluxmm2, bal_sfluxmm)
993      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
994        including separate counting and multipliers
995    o pkg/rbcs
996      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
997    
998    checkpoint58k_post
999    o testreport:
1000     - always build in dir. "build" (if not there, mkdir build instead of building
1001       & running in input)
1002     - run in dir run (if it exists), in build otherwise.
1003     - call prepare_run (if input/prepare_run exists)
1004     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1005    o pkg/exf modifications to interpolation and rotation routines for more
1006       reasonable treatment of North Pole singularity: for tracers North Pole
1007       value is set to northernmost zonal-mean value, for zonal velocity it is
1008       set to zero, and for meridional velocity it is set to northernmost value.
1009    o pkg/exf/exf_check_range.F
1010     - add tile index to diagnostics and move stop statement to the very
1011       end of the routine.
1012    o pkg/diagnostics: (diagnostics_main_init.F)
1013      define title of isomorphic variables according to the current config.
1014    o pkg/thsice with pkg/seaice dynamics:
1015    - fix domain of computation (interior only, required for exf) and do exchanges
1016    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1017    o towards a standard way of dealing with multi-threading in MONITOR
1018      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1019    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1020       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1021    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1022    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1023    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1024       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1025    o tracer advection:
1026     - clean-up and simplify calc_common_factors.F
1027     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1028       advection subroutine (but still not used within DST advection S/R)
1029    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1030    
1031    checkpoint58j_post
1032    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1033      from file (collects calls previously in FORWARD_STEP)
1034    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1035    o adjoint store dir. adjusted accordingly
1036    o genmake2
1037      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1038    
1039    checkpoint58i_post
1040    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1041      on wind stress (SEAICEstressFactor defaults to 1.)
1042    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1043      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1044    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1045      on CS-grid: no longer loosing mass.
1046    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1047    o pkg/ggl90: fix sloppy output and fix a bug
1048    o pkg/seaice: added SEAICEuseEVPpickup parameter
1049      - Set to false in order to start EVP solver with
1050        non-EVP pickup files when using SEAICEuseEVP
1051      - fix sign error in diffusion in seaice_calc_rhs
1052    
1053    checkpoint58h_post
1054    * Modifications for bottom topography control
1055      o replace hFacC by _hFacC at various places
1056      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1057      o add non-self-adjoint cg2d_nsa
1058      o update autodiff support routines
1059      o re-initialise hfac after ctrl_depth_ini
1060      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1061    * Adding verification for 5x5 box (4-layer) bottom topography control
1062    
1063    checkpoint58g_post
1064    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1065       used for mean seasonal cycle, mean diurnal cycle); add an example
1066       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1067    o pkg/ggl90:
1068      - add parameter (minimum surface kinetic energy)
1069      - fix bug (avoiding division by zero)
1070    o couple pkg/thsice to pkg/seaice:
1071      - modify advection in seaice to accomodate new scalar fields to be advected
1072      - only muliDimAdection scheme work with seaice/thsice
1073      - mapping of thsice-variables to seaice-variables, back and forth
1074      - does not break the verification experiments, but does not give the
1075        desired results either
1076    o pkg/seaice
1077      - make (default) second order advection a bit less confusing?
1078    
1079    checkpoint58f_post
1080    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1081      to pkg/seaice):
1082      - new routines thsice_map_exf and thsice_get_exf provide the interface
1083      - add an additional formal parameter to thsice_solve4temp
1084    o pkg/exf:
1085      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1086      - correct Stefan-Boltzmann constant
1087      - new parameter for longwave surface emittance
1088      - separate some stuff from exf_bulkformulae into new routines  
1089        exf_radiation, exf_wind
1090      - add new parameters and constants: longwave emissivity for ocean, ice
1091        and snow, evaporation parameters over ice
1092      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1093        either wind from stress or stress from wind
1094    o pkg/thSIce:
1095    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1096    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1097       and THSICE_CALC_THICKN
1098    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1099    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1100      to make debugging easier.
1101    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1102    o pkg/bulk_force:
1103      - clean-up comments and parameters ;
1104      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1105    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1106      generate new output for test-experiment: aim.5l_cs.thSI
1107    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1108      testreport accordingly
1109    
1110    checkpoint58e_post
1111    o SEAICE_CGRID adjoint done
1112    o R_STAR adjoint implemented.
1113      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1114      * need to sort out init. of h0facc, etc.
1115    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1116      to be able to use it in pure forward.
1117    
1118    checkpoint58d_post
1119    o upgrade simple test-experiment to tutorial example:
1120     step.1: duplicate the experiment and (step.2) will remove the old copy.
1121      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1122      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1123      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1124      tutorial_global_oce_biogeo    <- copy of dic_example
1125      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1126      tutorial_plume_on_slope       <- copy of plume_on_slope
1127      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1128      tutorial_global_oce_optim     <- empty for now (David ?)
1129      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1130     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1131    o correct a sign problem in cost_scat.F
1132    o obcs and ptracers: fix boundary conditions for advections schemes
1133      with larger stencil
1134    o thsice adjoint: start
1135    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1136      completeness
1137    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1138      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1139    o ptracers adjoint:
1140      * avoid extensive recomputatations
1141      * fix missing re-init. of gptr (missed by TAF)
1142    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1143      me to turn off the excessive output to STDOUT that this package produces
1144    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1145      and add those terms in Vector-Invariant formulation.
1146    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1147      if the control period (xx_hfluxperiod etc) is 0
1148    o in profiles pkg, clean routines and fix details
1149    o in ecco pkg, reading ssh data:
1150      fix problem in case the model does not start at iter0=0
1151    o fix mnc-pickup/restart for ptracers
1152    o new package prifiles:
1153      code to compute profile-based cost by Gael Forget
1154      (modifs in ecco, ctrl, autodiff)
1155    o Benign bug fix in initialization (spotted by M. Mazloff) of
1156      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1157    
1158    checkpoint58c_post
1159    o adjoint: finish NLFS adjoint and provide reference output in
1160      verification/global_ocean.90x40x15/results_ad_nlfs
1161    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1162      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1163      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1164      with SEAICE_CGRID defined.
1165    o move calendarDumps from "data" to "data.cal" and clean-up the code
1166      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1167    o add useEXF & useCAL flags (for now, set in hard-coded way)
1168    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1169      (were missing in NH mode, and wrong in quasihydrostatic mode).
1170      waiting for Chris updated version of calc_gw to add those CALLs.
1171    o fix bug in quasihydrostatic S/R ;
1172      add a test for this option: global_ocean.90x40x15.qshyd
1173    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1174      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1175    o add on/off flag useOffLine for package OFFLINE
1176    o seaice:
1177      - modify advection so that it works also on the C-grid
1178      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1179        problem in multi-tile runs with C-grid
1180      - add flags for clipping ice velocities and/or masking solver forcing
1181      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1182        C-grid solver
1183      - added a few comments to seaice_diffusion.F
1184      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1185        are now exclusive)
1186      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1187        required re-ordering the code a little:
1188       + make DAIRN global variable (defined in SEAICE)
1189       + move computation of the viscosities eta and zeta into a new separate
1190         routine (because I need to recompute them in seaice_ocean_stress.F)
1191    
1192    checkpoint58b_post
1193    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1194      update output.txt of exp. aim.5l_cs.thSI
1195    o various mnc cleanups and improvements:
1196      + shrink lookup tables by factor of ~4
1197      + better error reporting when running out of lookup space
1198      + able to handle longer path/file names (up to 500 chars)
1199    o adjoint:
1200      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1201      - TBD: "hidden" mom_vecinv recomp. in dynamics
1202    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1203     (allow to differentiate between forcing components using new integer flags:
1204      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1205     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1206    o ecco
1207      - enable trend removal from SSH anomaly obs.
1208    o adjoint
1209      - a fix for PmEpR when #undef EXACT_CONSERV
1210      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1211      - try to fix "hidden" recomp. in forward_step for NLFS
1212        (NLFS seems broken sometimes after I checked it in)
1213    o seaice:
1214     - add c-grid version of the dynamic solver:
1215       + three new routines that are the c-grid substitute lsr, dynsolver
1216         and ostres
1217       + put a few fields that were local to dynsolver into global common
1218         blocks, so that I can move the computation of stresses etc into
1219         seaice_lsr (saves coding but may break the adjoint).
1220     - replace more hardwired parameters by runtime parameters
1221     - add ice masks that mask the rhs of the implicit solvers where there
1222       is no ice (commented out in seaice_dynsolver, because i am not sure
1223       if this works properly), eventually this should replace the clipping
1224       of ice velocities in seaice_dynsolver to +/-40cm/s.
1225    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1226      include it only where its needed
1227    o move balancing of fluxes before the call of external_forcing_surf
1228    o seaice:
1229      - correct units of turning angles (now they are really in degrees)
1230      - move computation of GWATX/Y out of main routine into dynsolver
1231      - initialize GWATX/Y in seaice_init
1232    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1233      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1234    o seaice: add runtime flags for turning angles (default to zero)
1235    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1236      and trend from exf forcing and ctrl control adjustments
1237    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1238      (since checkpoint57x_post)
1239    o change the default rotation period to 86164.s = the Earth rotation
1240    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1241      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1242    o seaice advection: add code for choosing between the default (2nd order
1243      central differences) and multiDim advection schemes provided by
1244      pkg/generic_advdiff
1245    o seaice:
1246      - removed all references to SEAICE_GRID.h fields from
1247        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1248        (cubed-sphere configuration will change a little)
1249      - grid computations in seaice_init are obsolete now.
1250      - cleaned up code a little so that is easier to read (hopefully).
1251      - added new (better?) discretizations of default advection and diffusion
1252        (turn on with SEAICEuseFluxForm)
1253      - replace 1 in 3d global fields by kSurface in growth.F
1254      
1255    checkpoint58a_post
1256    o seaice:
1257      - bug fix in advect.F
1258    o shelfice:
1259      - separate shelfice load anomaly from pload (breaks with time
1260        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1261        Its default is 0., but it may be computed more cleverly from (unknown)
1262        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1263        done offline. A good approximation of the pressure load anomaly is
1264        necessary to avoid large initial adjustment processes underneath
1265        deep-reaching shelfice.
1266      - small fix in ISOMIP shelfice_thermodynamics
1267      - add more sophisticated thermodynamics of Hellmer (1989), this is
1268        now the default
1269      - give a few constants more intuitive names
1270    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1271      if bulk formulae are used in long integration (especially EmPmR). Turn
1272      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1273      if balancePrintMean, the imbalance that is substracted is printed to
1274      STDOUT.
1275    o fix bug (typo) in obcs_apply_eta.F
1276    o add a new package shelfice which enables us to model the circulation
1277      underneath shelf-ice with draughts of hundreds of meters.
1278     - works
1279     - to do: + include improved thermodynamics
1280              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1281                instead of new field kTopC
1282              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1283                instead of new field R_shelfIce and new code in ini_depth.F
1284                and ini_mask_etc.F?
1285              + adjust vertical mixing schemes?
1286    o seaice pkg:
1287     - add a cpp-flag to include a simple formula for a salinity dependent
1288       freezing point of sea water at the surface
1289     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1290       meridional stresses are now different (and hopefully correct)
1291    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1292       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1293       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1294    o pkg/diagnostics: add options and parameters for regional-statistics
1295       diagnostics ; define regions by reading a region-mask from a file
1296       (might add other options later)
1297    o pkg/bulk_force:
1298     - add option and parameters to use AIM surface-flux formulae.
1299     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1300       others forcing fields (defined in PARM05, parameter file "data") are loaded
1301       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1302     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1303     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1304     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1305       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1306     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1307    
1308    checkpoint58
1309    o add "--embed-source" option to genmake2 which, when the supporting
1310      tools can be compiled (as determined by genmake2) will turn on the
1311      embed_files package which then embeds the entire MITgcm source code
1312      (*.[fFhc] + Makefile) used for the build within the executable
1313      - requested by CNH but off by default
1314      - adds a paltry <9MB to the mitgcmuv executable in most cases
1315      - only writes the output when useEMBEDSRC in eedata is true
1316    o clean up 3-dim. relaxation codes:
1317      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1318      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1319      * Thanks to Tom Haine for testing!
1320    
1321    checkpoint57z_post
1322    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1323      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1324    o fix the pickup behavior for obcs in combination with ptracers
1325    o fix a bug in ptracers_external_fields_load
1326    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1327      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1328    o transfered surface NH pressure to eta field (if exactConserv).
1329    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1330         and update lab_sea output.txt file.
1331    o completing 3-dim. relaxation code: additional term
1332         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1333      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1334      * At compile time, in "EXF_OPTIONS.h" set
1335          #define  ALLOW_CLIMTEMP_RELAXATION
1336          #define  ALLOW_CLIMSALT_RELAXATION
1337      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1338          tauThetaClimRelax3Dim = 15552000.0,
1339          tauSaltClimRelax3Dim  = 15552000.0,
1340      * 3 cases:
1341          1) Use a constant-in-time 3-dim. field
1342          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1343          3) Real-time relax. to time-evolving prescribed field
1344    o Adding Laplacian-type smoothness constraint on
1345      initial and boundary (forcing) controls (ic, bc)
1346      * enable at compile-time via
1347        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1348      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1349      * Absolute scale somewhat unclear so far
1350      * no area weighting was included since no other cost term does so far
1351    
1352    checkpoint57y_post
1353    First step for a NLFS adjoint
1354    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1355    o new init. routines for calc_r_star, calc_surf_dr
1356    o still need to deal with ini_masks_etc
1357    o testreport seemed happy
1358    checkpoint57y_pre
1359    
1360    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1361    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1362    o add new offset feature to offline pkg (plus minor cleanup)
1363    o cfc fixes for final year of integration
1364    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1365      be in GCHEM_OPTIONS).
1366    
1367    checkpoint57x_post
1368    o fix testreport Pb in multiple test experiment.
1369    o cleanup our namelist syntax in verification:
1370      - make it more F95 standards compliant (some work still needed)
1371      - allows the vast majority of our tests to work with gfortran
1372    o Non-Hydrostatic:
1373     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1374     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1375    o Allow to apply AB on T,S rather than on AB(gT,gS):
1376     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1377     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1378       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1379     - need a "clever" read_pickup to restart from the other AB formulation
1380    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1381    o remove some unused variables (reduces number of compiler warnings)
1382    o adjoint
1383      * Disable useVariableViscosity for adjoint for time being
1384        (there are a number of extensive recomputations)
1385      * Initialize certain variables needed for adjoint
1386    
1387    checkpoint57w_post
1388    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1389                 fix the singleCpuIO RS version of MDSWRITEFIELD
1390       and add a WARNING if using globalFiles=T with multi-processors.
1391    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1392      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1393    o tracer advection scheme:
1394      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1395       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1396       was not very convenient).
1397      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1398       (further tests needed for the implicit DST & Flux-Limiter schemes).
1399    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1400      and sRef for convenience, handy, when you want to initialize
1401      ptracers in a large domain with a constant non-zero value. Also,
1402      untangle ptracers_init.F a little.
1403    
1404    checkpoint57v_post
1405    o change dome exp. to use variable viscosity in side-drag terms.
1406    o remove all the files from the cfc_offline test since they are now
1407      incorporated into tutorial_cfc_offline which has been producing
1408      identical results for a few days of testing
1409    o add new parameter: sideDragFactor to enable half-slip-side BC
1410      and change side-drag S/R to use viscosity from mom_calc_visc
1411      (can switch back by setting sideDragFactor=0.); affects results at
1412      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1413       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1414    o vorticity & strain are now computed without masking, to account for
1415      no-slip-side BC in variable viscosity calculation ; mask is applied
1416      anyway later on, before computing advection/coriolis terms.
1417    o modify exp4 to test new obcs support for reading from external files
1418      and for passive tracers
1419    o fix behavior of ptracers_monitor when monitor output is written to a
1420      netcdf-file; still not independent of monitor.F (writes in the same
1421      file).
1422    o change default value of tRef (put a uniform, meaningful value for ocean
1423      & atmos) and initialize sRef (was missing, as Martin mentioned).
1424    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1425      to be proportional to enstrophy dissipation length.  Thus,
1426       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1427      This is now consistent with Smagorinsky and with the manual.
1428    
1429    checkpoint57u_post
1430    o OBCS and PTRACERS: add open boundary support for passive tracers
1431      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1432        OB-values from file; this is not different from the way theta and salinity
1433        are treated
1434      - however, Orlanski-radiation conditions are not supported, and the model
1435        will stop if you use pTracers and Orlanski at the same time.
1436      - beefed up the rountine obcs_external_fields_load: now only those open
1437        boundary values are overwritten with values from files for which there
1438        are really files, otherwise the OB-fields remain untouched. This makes
1439        it possible to use different OBs at different ends of the domain (as
1440        with EXF)
1441    o reduce number of exch calls in shap_filt (s2).
1442    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1443      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1444    
1445    checkpoint57t_post
1446    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1447    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1448      same truncation, independent of the face number: affects affects several
1449      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1450    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1451      note that biharmonic viscosity + no-slip was not tested in any experiment.
1452    o fix bug in non-linear free-surf side-drag ; generate new output for
1453      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1454    o make mnc honor the writeBinaryPrec flag for most kinds of output
1455    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1456    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1457      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1458    o add brackets in multi-terms sum to get same truncation, independent of
1459      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1460      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1461    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1462      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1463      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1464      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1465      Suggested values of viscosity parameters found in mom_calc_visc.
1466      Many new viscosity diagnostics available.
1467    
1468    checkpoint57s_post
1469    o Add clearing-house for viscosity calculations, mom_calc_visc and
1470      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1471      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1472      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1473      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1474      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1475      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1476      ViscAhStrain and viscAhTension are now retired.
1477    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1478    o In response to JMC's bug report, genmake2 now ignores any soft-links
1479      that it finds in the *current* directory when searching for files.
1480      Soft-links found in any other source directories will still work as
1481      they did before.
1482    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1483      a C routine to unlimit the stack size
1484    o mnc-ify pkg/aim snapshot vars
1485    o mnc-ify pkg/land as requested by Daniel
1486    o various changes to mnc including:
1487      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1488      - output can now be grouped so that all files within a group
1489          change the ITER portion of their names in lock-step together
1490      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1491          and works with both EXCH1 and EXCH2 (but needs more testing)
1492      - writing works for all verification test cases w/ g77 on Linux
1493    
1494    checkpoint57r_post
1495    o make MNC variable initialization happen earlier
1496    o add diagnostics for (almost) each term of the momentum Eq.
1497    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1498    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1499    o remove MINIMAL_TAVE_OUTPUT option ;
1500      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1501    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1502      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1503    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1504    o add time-dependent SST, SSS control
1505    o cost terms in ecco/ modularized (new cost_generic.F)
1506    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1507    o new infrastructure for seaice model vs. obs misfits in seaice/
1508      * driver from the_main_loop.F is seaice_cost_driver.F
1509      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1510      * gradient check in Exp. 6a of natl_box_adjoint/
1511    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1512      (see README file)
1513    
1514    checkpoint57q_post
1515    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1516    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1517      - bug was reported by Jean-Michel and Ian Fenty
1518    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1519      update exp. cpl_aim+ocn output.
1520    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1521      Needed for high-res. runs with large global files
1522      to be able to limit tapelev size
1523    o Changed some tests for adjoint:
1524      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1525      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1526      * global_ocean.90x40x15/ back to default 3-level checkpointing
1527    o Modifications to enable scripted COMMON to MODULE conversion
1528      * verification/OpenAD/code/ has necessary scripts and description;
1529      * converts, compiles and runs successfully;
1530    
1531    checkpoint57p_post
1532    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1533    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1534      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1535    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1536    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1537      (was already the case for dissipation with mom_vecinv,
1538       and also the case for grad.PhiHyd when staggered-timeStep)
1539      This will allow to put dissipation out-off the AB time-stepping.
1540     Unfortunately, affects truncation error. Update output of exp. that "fails"
1541      (cg2d matching number) and leave the others for later: front_relax(10),
1542      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1543      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1544    
1545    checkpoint57o_post
1546    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1547      (2) its ready to be documented during the 20050801 DocFest
1548    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1549      for ideal_2D_oce and lab_sea on linux_ia32_g77
1550    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1551      in global1x1_tot/code_seaice_adj to access indices 32, 33
1552      (worth another tag)
1553    
1554    checkpoint57n_post
1555    o adding precip control xx_precip 32
1556    o adding swflux control xx_swflux 33
1557    o Replacing 10 forcing penalty cost routines by 1 generic.
1558    o Implementing partitioning in time-mean and variable adjustment
1559      for atmos. state.
1560    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1561    o in natl_box_adjoint:
1562      * updated exp 1 to 10
1563        (but does not have time-mean vs. variable split results yet)
1564    o updated global1x1/*_seaice_adj/
1565      to incorporate latest changes
1566    o enable useSingleCpuIO for mdsio vector routines
1567      (applies in particular to tapelev I/O)
1568    o removed inefficient K-loop in all active_file*control*.F
1569    
1570    checkpoint57m_post
1571    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1572      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1573    o pkg/exch2: filling of face-corner halo regions is optional
1574      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1575    
1576    checkpoint57l_post
1577     tag before updating tutorials (pre-release-2)
1578    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1579       for output and interpolation of input fields onto model grid)
1580    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1581       Affects results of exp. rotating_tank ; update output.txt.
1582    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1583          and taking the square quantity and/or using a fraction-weight field.
1584    o fix aim_diagnostics_init.F mate numbers.
1585    o add mnc output capability to diagnostics/diagstat and update
1586      our cvsignore files for the ACSII output generated
1587    
1588    checkpoint57k_post
1589    o lab_sea now uses diagnostics package and provides a suite of
1590      new EXF diagnostics output.
1591    
1592    checkpoint57j_post
1593    o exf
1594      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1595        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1596        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1597      * extended diagnostics output
1598        - now includes all EXF variables
1599        - hs, hl moved to common block
1600        - separate S/R for diagnostics, called after ctrl vector is added
1601        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1602        - EXFqnet contains true Qnet (i.e. includes qsw)
1603      * updated verif. lab_sea, global_with_exf
1604      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1605        to ensure that diagnostics sees a true EXFqnet
1606    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1607    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1608      several times with different frequencies.
1609    o mnc-ify the thsice package as requested by Daniel Enderton
1610      - the monitor--MNC output needs work
1611      - many attributes need to be added (most are currently blank)
1612    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1613      - many attributes need to be added (most are currently blank)
1614    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1615    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1616    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1617      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1618         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1619    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1620     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1621    
1622    checkpoint57i_post
1623    o Diagnostics package was changed: diagnostic allocation is now deactivated
1624      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1625    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1626      add 1rst Order upwind vertical Shear.
1627    o add a quick fix for A/B checkpointing in OFFLINE mode
1628    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1629      end-run around the C/Fortran linking horror in eesup/src/timers.F
1630    o added pkg/runclock: allows user to terminate run based on wall clock
1631    o added non-hydrostatic scaling parameter: nh_am2
1632    o pkg/my82: futile attempt to make results compiler-independent by adding
1633      some "_d 0", etc. no effect.
1634    o for mnc output, fill the 'T' coordinate var with myTime and create a
1635      separate 'iter' variable for iteration count
1636    o pkg/diagnostics:
1637      add new capability: output of Global/Regional & per-level statistics ;
1638      tested against monitor output (including land & thSIce) on various exp.
1639    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1640    
1641    checkpoint57h_done
1642      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1643      data.diagnostics, data.gchem, data.ptracers) is done.
1644    
1645    o pkg/diagnostics: prepare for Global/Regional statistics.
1646      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1647    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1648      and rename it: DIFFERENT_MULTIPLE
1649    
1650    checkpoint57h_post
1651    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1652    o pkg/diagnostics: change output frequency, now in seconds (instead
1653      of Nb of iterations). This requires to change data.diagnostics.
1654    checkpoint57h_pre
1655    
1656    o in mnc, let the user create the output dir if both mnc_outdir_date
1657      and mnc_outdir_num are false
1658    o add fflags() to pkg/diagnostics which allows one to specify, on a
1659      per-file basis, the file precision [default behavior is unchanged]
1660    o added diagnostics to pkg/kpp, including computation of mixed layer
1661      depth based on a temperature/density criterion
1662    o updated verification/natl_box to test the new pkg/kpp diagnostics
1663    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1664    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1665    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1666      not mnc -- this mistake was found by JMC and is now corrected
1667    
1668    checkpoint57g_post
1669    o add Adams-Bashforth 3rd Order time stepping:
1670      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1671      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1672    checkpoint57g_pre
1673    
1674    o make lambda[Theta,Salt]ClimRelax spatially varying
1675      (default remains spatially uniform constant based on tau)
1676    o added new control variables
1677      * init. uVel, vVel, etanN
1678      * lambda[Theta,Salt]ClimRelax
1679    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1680      (suggested by G. Forget)
1681    
1682    checkpoint57f_post
1683    o add parameter "baseTime" = model base time = time at iteration zero
1684      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1685      account for baseTime shift
1686    o move Coriolis arrays from PARAMS.h to GRID.h
1687    checkpoint57f_pre
1688    
1689    o mnc-ifying the seaice package
1690    o introduced an alternative length scale calculation for use in the limiting
1691      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1692    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1693    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1694      as well as grad(vort3).  Made it compatible with both approximate form
1695      for the cubed sphere and full form of these gradients.  Added flag
1696      useFullLeith to select between approximate and full form.  
1697    o add "d0" in getcon.F to reduce differences between compilers/platforms
1698      update output.txt of exp. fizhi-gridalt-hs
1699    o change port_rand funtion to allow to set the seed.
1700    o fix obscure MNC bug involving conversion between reals and integers
1701      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1702        new version is now more standards-compliant
1703    o adjoint-related modifications
1704      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1705      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1706      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1707    
1708    checkpoint57e_post
1709    o Adding eddy stress controls a la Ferreira et al.
1710    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1711    
1712    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1713      update output.txt of exp. fizhi-gridalt-hs
1714    o add more "Z" dimensions and associated coordinate vars to MNC
1715    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1716    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1717      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1718      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1719      months and years.  Requires pkg/cal.
1720    o diagnostics: add pickup functionality
1721      - off by default for backwards compatibility
1722      - current version only uses MDSIO -- MNC will be added
1723    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1724    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1725    
1726    checkpoint57d_post
1727    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1728    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1729      output from the diagnostics package
1730    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1731    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1732      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1733    o add coordinate variables to the MNC output from the diagnostics package
1734    o change MNC-flags default value: true when useMNC=TRUE
1735    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1736      the ability (off by default) to read the grid information using MNC
1737    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1738    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1739    o do snap-shot diagnostics at the middle of the time-interval (instead of
1740      at the end).
1741    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1742      new test for AIM with thSIce + slab-ocean
1743    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1744    o move state variable diagnostics to the beginning of the time step ;
1745      (note: still needs some work specially for snap-shot diagnostics)
1746      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1747    
1748    checkpoint57c_post
1749    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1750    o generate new output.txt files on faulks with g77 & the new -ieee option
1751    checkpoint57c_pre
1752    
1753    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1754      update output.txt of exp. global_ocean.90x40x15
1755    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1756      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1757    o add saltFlux(+File) forcing capability with periodicExternalForcing
1758    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1759    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1760    o improvements for the MNC output from DIAGNOSTICS:
1761      - correct handling of the unlimitied dimension
1762      - all dims now have associated coordinate variables
1763      - variables located at U, V, and Corner ("Z") points are now written
1764        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1765        *all* data points are output
1766    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1767    o added pkg/seaice/seaice_monitor.F
1768    o mdsio_readfield.F can now read files visible only to master MPI process.
1769    o pkg/seaice: some test code for ice-modified ocean stress
1770    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1771      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1772      spurious negative numbers for precipitation and humidity.  Will cause
1773      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1774    o pkg/ctrl/
1775      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1776        May be enabled via doPackDiag
1777      *  introduce z-scaling of
1778         + gradient (doZscalePack) and
1779         + control (doZscaleUnpack)
1780    o pkg/mdsio/
1781      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1782      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1783    
1784    checkpoint57b_post
1785    o simplify options in diagnostics_fill arguments (remove weird combinations)
1786    o fix MNC coordinate variables so that they now contain per-face index
1787      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1788      general, EXCH2 grids are only aligned to a "local" coordinate system
1789    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1790    o Implement instantaneous output within pkg diagnostics:
1791      setting a negative frequency in data.diagnostics produces
1792     "snap-shot" output (as opposed to time-average if freq > 0)
1793    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1794      NOTE: change ptracer diagnostics name: use 2 characters to work with
1795            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1796    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1797      becomes the coordinate variable for the 'T' dimension
1798    o add CF-style coordinate variables to MNC
1799      - just a first cut:  numbers are meaningless on the cubesphere and
1800        missing along the T axis but otherwise it works!
1801    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1802    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1803    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1804      this is based directly on what the model compute, so that the content of
1805      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1806    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1807    o clean up build options files for SunOS, in particular
1808      - remove -traditional from xmakedepend
1809      - change -xarch=v9 to -xarch=native for f77
1810      - restore use of make (not gmake)
1811      - add CC=gcc if using g77
1812    o changes per discussion of AM, JMC, & EH3 today:
1813      - move redundant "grid" variables out of "state" -- in preparation of
1814        creating proper CF-style coordinate variables and in recognition
1815        that any/all grid variables can be easily copied (eg. w/NCO) from
1816        the grid files into any of the other NetCDF files
1817      - *always* output grid variables with MDSIO (this will eventually be
1818        changed)
1819      - output MNC grid file if useMNC is true
1820    o every instance of _END_MASTER() has been found and replaced with
1821      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1822      preprocessors
1823    o re-arrange diagnostics pkg initialisation:
1824     - allow each package to extend the available diagnostics list
1825     - add some checking and fix small problems (multi-threaded, ...)
1826     - new S/R diagnostics_fill (replace fill_diagnostics):
1827       look through the short list of active diag. (instead of the long list)
1828       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1829    
1830    checkpoint57a_post
1831    o this set of changes restores TAMC compatibility
1832      tested for global_ocean.90x40x15 adjoint on trough
1833      (what a pain)
1834    
1835    checkpoint57a_pre
1836    o some modifs in tools/build_options for sunos
1837    o call ctrl_pack for ctrl at end for optimcycle=0
1838    
1839    checkpoint57
1840    o add horizontal bi-harmonic viscosity for vertical velocity
1841      - new parameter viscA4W (defaults to viscA4)
1842      - affects only non-hydrostatic code
1843      - to be done: no-slip lateral boundary conditions
1844    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1845    o implement Implicit Vertical advection for pTracers
1846    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1847      (implemented also for implicit vertical diffusion & advection)
1848    o OBCS: extend application of tracer open boundary conditions
1849      to a strip beyond the boundary of width Olx/Oly
1850    o add call monitor to TAF set of required calls (flow directives)
1851      and include in natl_box_adjoint
1852    o untangle a few ifdefs related to cost, ctrl, autodiff
1853      untangel a few ALLOW_ECCO_OPTIMIZATION
1854    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1855      (theta2, salt2 in ecco_cost_weights)
1856    
1857    checkpoint56c_post
1858    o OBCS as control variables
1859      - update ctrl_ad_diff.list, obcs_ad_diff.list
1860      - remove balance of obcs controls from default
1861      - fix index bug nobcs in ctrl_init
1862      - fix dummy fields filen in ctrl_pack
1863      - add dummy weights for obcs
1864    o lsopt: comment out fort.94 output
1865    o optim:
1866      - remove unnecessary header files
1867      - adjusted namelists
1868      - add xerbla.F to Makefile
1869    o exf:
1870      - multiple modifications of exf_check_range
1871      - unit change in exf_init_runoff from [m/year] to [m/s]
1872    o mdsio:
1873      - i/o-vector change debugLevel from debLevA to debLevB
1874    
1875    checkpoint56b_post
1876    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1877      is called from DO_THE_MODEL_IO
1878      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1879      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1880      - clean up PTRACERS_WRITE_TIMEAVE a little
1881    o add another verification experiment that tests both the cfc-pkg and
1882      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1883      reactive tendencies treated inline with regular timestepping
1884    o testreport previously did a lousy job of comparing small numbers, so
1885      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1886      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1887      testreport.
1888    o ptracers_monitor: bug fix for MPI
1889    
1890    checkpoint56a_post
1891    o GCHEM: finish reorganizating the package
1892      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1893        (introduces another 3D-array for each passive tracer, but only if
1894        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1895        gchemTendency is not needed because the timestep is done separately)
1896      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1897      - GCHEM is now---more or less cleanly---separate from PTRACERS
1898      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1899        so clear to me how that should be done in a general way.
1900    o CFC: improve formatting of output in CFC_ATMOS
1901    o PTRACERS:
1902      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1903        that ALL experiments with ptracers enable can be checked. This makes
1904        GCHEM_MONITOR obsolete.
1905      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1906        monitorFreq
1907      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1908    o add PTRACERS (PTR0[1-5]) to testreport output
1909    o exf_check_range:
1910      * default changed to .TRUE.
1911      * will check values for niter0 if debLevA, every timestep if debLevB
1912      * STOP in exf_check_range if 'out of range'
1913      * range chosen generous to allow for potential extema
1914      TBD: a version with stricter range
1915           permitted range would be runtime parameters
1916  o GMredi:  o GMredi:
1917    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1918    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
# Line 11  o GCHEM: Line 1921  o GCHEM:
1921    - move call to GCHEM_FORCING_SEP, so that it is now called before    - move call to GCHEM_FORCING_SEP, so that it is now called before

1923    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1924      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1925        this flag is now only visible within GCHEM-pkg routines.
1926      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1927        be replaced by a 3D array that is computed before thermodynamics; for
1928        this, the tracer ID iTracer had to be included into the parameter list
1929        of ptracers_forcing
1930      - set up forward_step to call gchem_forcing, that will replace
1931        gchem_forcing_int in ptracers_forcing
1932      - cleaning up
1933  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
