4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o move getcon.F from model/src to pkg/fizhi.
8    o pkg/exf: add parameter for extrapolation of temp up to the surface
9       and option to prevent negative evap (in bulk_largeyeager04 only).
10    o Prather Advection scheme: fix tracer conservation for divergent flow
11      (e.g., when using NonLin Free-Surface).
12    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
13    o gmredi (Visbeck-variable-K):
14     - add more parameters to Visbeck-variable-K.
15     - use a 5 points average for dSigmaR in Visbeck-K calculation
16       (more "homogenous": same stencil and same weights as in dSigmaH)
17     - update output of ideal_2D_oce experiment.
18    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
19      (#undef REAL4_IS_SLOW)
20     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
21       coordinate variable
22     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
23       (surface forcing fields), removes some of the functionality
24     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
25     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
26       probably not all: copy _RS surface flux fields to RL field before
27       calling DIAGNOSTICS_FILL
28     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
29       real*4 (CALL EXCH_*_RS) versions.
30     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
31       (generate new output).
32    
33    checkpoint61e
34    o gmredi (Visbeck-variable-K):
35      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
36      - change computation of Visbeck-K where Slope > Smax :        
37        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
38        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
39    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
40      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
41    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
42    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
43      does not become too large (to avoid precision problems in implicit-diffusion
44      solver); update ideal_2D_oce output.
45    o pkg ggl90:
46      - in ggl90_cal.F: compute only one set of visc/diff, used to
47        step forward TKE/T/S/momentum
48      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
49        have Prandlt =1)
50    o gmredi (fm07):
51      - add lower limit on Transition layer thickness + lower limit on 1/lambda
52      - allow to set few more params from data.gmredi
53    o pkg ggl90:
54          - add missing sqrt(2) factor in computation of mixing length
55            scale in ggl90_calc.F
56            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
57    
58    checkpoint61d
59    o adjoint modifs
60      - adapt to new field rhoInSitu
61      - allow to revert from StoreDynVars2D, StoreDynVars3D
62        to individual fields
63        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
64    o store 3-D (in-situ) density in commom block (DYNVARS.h)
65     - save 1 rho computation.
66     - no longer modify T & S inland when using down_slope pkg.
67    o gad_som : allow to switch to SOM advection for T & S without corresponding
68      pickup files (using new S/R: MDS_CHECK4FILE).
69    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
70      (for useSingleCpuIO to work in multi-threaded)
71    o pkg/shelfice:
72     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
73       with SHELFICEtopoFile in data.shelfice
74     - move code for reading ice shelf topography and modifying hFacC into separate
75       subroutines of the shelfice package
76     - separate initialisation of "fixed" and "variable" variables
77     - kTopC is not (yet) replaced by kSurfC, although this is possible
78    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
79    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
80      and rename:
81      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
82      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
83    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
84    
85    checkpoint61c
86    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
87      to add mass source/sink of fluid in the interior (3-D generalisation
88      of oceanic real-fresh water flux).
89    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
90    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
91    o new pkg: down_slope
92      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
93      - presently, modify T & S inland (dwnslp_calc_rho.F).
94        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
95      - implementation for ocean in P-coords not tested.
96      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
97    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
98      (to facilitate conversion of oceanic pkg to p-coordinate).
99    o change FIND_RHO to FIND_RHO_2D :
100      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
101    o new pkg: cheapaml
102    
103    checkpoint61b
104    o exch2:
105      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
106      - no longer depend on the order sequence (N,S,E,W).
107      - 3rd exchange no longer needed (tested with 24 tiles).
108      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
109      - exch_UV_A-grid readily available (but not yet tested).
110      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
111      (both are no longer needed) in exch_uv: no effect in forward run; but
112       get truncation error differences with adjoint exch.
113    o exch2:
114     - change index-bounds storage (moved from target to local tile,
115       more intuitive this way) ; rename/remove some variables.
116     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
117    
118    checkpoint61a
119    o exch2/matlab-topology-generator:
120      fix bug in index bounds for N-S internal exchange (hard to tell if this
121      had any effect on the solution).
122    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
123      is exceeded
124    o testreport: modify syntax of awk, so that it works also with
125      awk, and not only with nawk and gawk
126    
127    checkpoint61
128    o autodiff
129      Change default for TAF usage by removing argument '-nonew_arg'
130      This changes TAF subroutine argument list (ordering of active var.)
131      Omission of this flag leads to incompatibility w.r.t. TAMC
132      To restore TAMC-compatibility, need following modifs:
133      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
134      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
135      Tested TAF version is 1.9.22
136      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
137    
138    checkpoint60
139    --->>> This is the last checkpoint for which generating the adjoint
140    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
141    --->>> by default.
142    --->>> Future checkpoints will ommit this flag by default.
143    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
144    o pkg/grdchk: Add gradient check to etan0 perturbations.
145    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
146    o pkg/autodiff: more flexibility in zeroadj.
147      model/src: modifying do_oceanic_phys.F accordingly.
148    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
149    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
150      special setup of gmredi for which the adjoint is stable
151      enough for parameter optimization.
152    o bridging the gap between eddy stress and GM.
153      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
154          along with a change in CPP option (now ALLOW_EDDYPSI).
155      -> when using GM w/ GM_AdvForm:
156          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
157          is applied either in the tracer Eq. or in momentum Eq.
158          depending on data.gmredi (intro. GM_InMomAsStress).
159      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
160      The key modifications are in model/src/taueddy_external_forcing.F
161      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
162    
163    checkpoint59r
164    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
165      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
166      fix option to read coriolis(@ cell-corner) from files with CS-grid.
167    o pkg/mnc: add some attributes to standard 1D-coordinate variables
168    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
169      mass points, when using mnc for output
170      - add runtime parameter (missing_value, missing_value_int) to override
171        default (which is the value of getcon('UNDEF'))
172    o pkg/mnc: prepare mnc for the actual use of missing values with the
173      diagnostics package: small fix in mnc_cw_readwrite.template and more
174      initialisation of never used fields
175      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
176      versions
177    o pkg/thsice/thsice_ini_vars.F added default initial values so that
178      thermodynamics sea ice solver does not blow up when some initial fields
179      are missing.
180    o move from external_forcing_surf.F to ini_forcing.F
181      the p-coord. hack consisting in using pLoad to set phi0surf ;
182      update output of tutorial_global_oce_in_p (affected @ truncation level).
183    o Freshen up a bit hs94.1x64x5, notably:
184      remove rotationPeriod and tRef=5*0. (adjoint only), and add
185      exactConserv=.TRUE.
186    o pkg/generic_advdiff:
187      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
188      applies to files where Temperature & Salinity 2nd Order moments are used.
189    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
190      this uses a dynamically allocated internal state data structure
191      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
192      and requires a fortran 90 compiler
193    
194    checkpoint59q
195    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
196       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
197    o Refresh tutorial_global_oce_biogeo, notably:
198      - change bathymetry (put back seamounts in ACC, use hFacs)
199      - change EOS (POLY3 --> JMD95Z)
200      - use Bryan-Lewis vertical diffusivity
201      - use multidimensional advection
202      - remove old virtual virtual in dic pkg, now done through ptracer pkg
203      - change a couple of parameters in dic pkg
204    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
205    o pkg/obcs: change default to OBCSfixTopo = .true.,
206      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
207      - replace "debugMode" with "debugLevel .GE. debLevB"
208    o implementation of TAF directives for gchem,cfc,dic
209    o remove "exp5" (replaced by tutorial_deep_convection).
210    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
211      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
212      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
213      --> changes results in exp4, seaice_obcs
214    o tutorial_deep_convection :
215      update the set-up and increase resolution and domain size ; start
216      from pseudo initial conditions = output at t=120mn in order to see
217      something happening when running testreport.
218    o pkg/seaice: add os7mp as an advection scheme
219                  add check for advection schemes
220                  add a flag for restoring T and S underneath sea ice
221    o pkg/my82: add netcdf-support and diagnostics
222    o thsice pkg:
223      - Now hsMax limits snow height by turning it into ice following
224        flooding scheme (and now conserving energy)
225      - Slight rewriting of the formula in thsice_calc_thick.F
226      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
227      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
228    
229    checkpoint59p
230    o gchem / dic / cfc :
231      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
232      - add new parameter files: "data.dic" & "data.cfc" ;
233      - various re-arrangement in initialisation & header file ;
234      - fix tutorial_global_oce_biogeo for multi-threaded test.
235    o pkg/dic: test for "pickup_dic" file when restarting ;
236      if no pickup-file, can restart with a re-initialised pH (same as it did
237      before) providing pickupStrictlyMatch is set to False.
238    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
239      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
240    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
241      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
242    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
243     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
244       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
245    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
246       scheme to use for vorticty-term ;
247     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
248       (with default selectVortScheme, return to original discretisation)
249     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
250    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
251    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
252      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
253      also fix diagnostics VISCAHW & VISCA4W.
254    
255    checkpoint59o
256    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
257    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
258      move a few statemens out the main loop into separate loops
259    o pkg/shelfice:
260      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
261        (kg/m^2/s), does not break tests, because in verification/isomip,
262        rhoConstFresh=rhoConst (by accident)
263      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
264      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
265        new file model/src/seawater.F, so that they are available for all pkgs.
266      - convert potential temperature into in-situ temperature. This changes the
267        isomip tests => update tests
268    o add a flag writePickupAtEnd (default=true) to be able to suppress
269      writing a pickup at the last timestep
270    o tools/mpack-1.6 :
271      - disable automake (not working) and autoconf (not needed).
272      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
273        also cleaner with much less compilation warnings.
274    o pkg/profiles:
275      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
276      (for "less than 32 characters name" compiler requirement)
277    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
278      conditions that have a different sampling frequency than S/T/U/V obcs
279    o pkg/diagnostics (stats-diags):
280      - fix global Min/Max in case 1 processor get only empty tiles
281    o genmake2: replace (4 times)
282         make genmake_tc_1.o >> genmake_warnings 2>&1
283      with
284         COMM="$CC $CFLAGS -c genmake_tc_1.c"
285         echo $COMM >> genmake_warnings
286         $COMM >> genmake_warnings 2>&1
287      to make genmake2 always see the value of CC as specified in the optfile.
288    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
289      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
290      - modify verification advect_cs test to test SOM-advection on CS-grid.
291    o pkg/ctrl:
292      - Rewrite of ctrl_map_ini_ecco.F,
293        introducing a generic routine (ctrl_map_ini_gen.F).
294      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
295    
296    checkpoint59n
297    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
298      number in dedicate array "hdiag":
299      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
300        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
301      - many small changes (integer format) for large number of diagnostics
302      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
303        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
304    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
305      usingSphericalGrid, this allows to define the rotated grid coordinates
306      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
307      geographical coordinates according to the inverse of the rotation defined
308      by the Euler angles, so that Coriolis parameter and online-interpolation by
309      exf works with the geographical coordinates on XC/YC/XG/YG.
310      Naturally, this feature does not work with all packages, so some
311      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
312      profiles), because there the coordinates are assumed to be regular
313      spherical grid coordinates.
314    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
315      - introduce isopycnal diffusion coefficient control.
316    o tools/adjoint_options:
317      - additional control vector components.
318    o pkg/mnc: have mnc create marginally meaning full coordinate variables
319      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
320    o pkg/mypackage:
321      - add example of read/write pickup for state-var ;
322      - add entry points to the main code for state-vars diags & write-pickup.
323    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
324      transitions for useExfYearlyFields
325      - add new subroutine that determines the file to read from for
326        use*YearlyFields = .TRUE. and .FALSE.
327      - add a verification experiment to global_with_exf that tests
328        useExfYearlyFields with USE_EXF_INTERPOLATION defined
329    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
330      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
331      subroutines (which could be generated from a template, because they are
332      almost identical), for now they are included in obcs_prescribe_read.F for
333      simplicity
334    o pkg/exf:
335      - add a little more diagnostic to exf_interp_read (in analogy to
336        mds_read_field, can be turned off with debugLevel < debugLevA=1)
337      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
338        ugly but fast by unrolling short inner loops, inserting a unroll=8
339        directive in routine lagran, and splitting a loop and making do while the
340        outermost loop (the latter requires the intoduction of index arrays)
341    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
342    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
343      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
344    o verification/seaice_obcs: updated for restart test and latest options
345    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
346      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
347      for now this is only available for the C-grid code and also within
348      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
349    
350    checkpoint59m
351    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
352      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
353    o gad_som : fix flux output (& diagnostics) to have same units as other  
354      advection scheme fluxes (was previously multiplied by deltaT).  
355    o added verification/seaice_obcs both to test seaice open boundaries
356      and to provide an example matlab scrpt for generating them
357    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
358    o pkg/salt_plume: clean up salt_plume_frac.F to
359      remove redundancy in PlumeMethod 1 and 4
360    o pkg/kpp: added saltplume diagnostics
361    o pkg/obcs and pkg/seaice:
362      - do not set uice and vice to zero when OB*icefile are unspecified
363      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
364      - moved seaice tracer obcs after call to seaice_growth
365    o pkg/salt_plume: added various options for salt plume depth
366      criterion and for vertical distribution of the salt
367    
368    checkpoint59l
369    o pkg/ptracers: new version of ptracers pickup:
370      read meta file and write only fields which are needed to restart.
371      ( same logic as main pickup file ; also using pickupStrictlyMatch )
372    o pkg/seaice:
373      - add timescale for melting due to warm mixed layer as a means of
374        setting SEAICE_availHeatFrac more conveniently
375      - add a CPP-flag/runtime parameter check for flooding algorithm
376      - reformulated availHeat in seaice_growth.F to be independent of AREA
377    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
378      unit changes
379    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
380    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
381      SX vector computer.
382    o pkg/seaice:
383      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
384        seaice forcing fields can now be read only through pkg/exf
385      - removed some unused halos
386    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
387    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
388      or U/VICE from U/VWIND before computing U/VSTRESS
389    
390    checkpoint59k
391    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
392      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
393    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
394      all experiments pass when compile with un-initialised var. checking option.
395    o added pkg/salt_plume
396    o script to test restart (for now, in MITgcm_contrib/jmc_script)
397    o pkg/seaice: new read/write pickup version.
398      read meta file and write only fields which are needed to restart.
399      ( same logic as main pickup file ; also using pickupStrictlyMatch )
400    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
401    o lab_sea.hb87: modify the domain & update output.hb87.txt :
402      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
403      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
404      process. Fixed here by closing the domain at the Northern boundary.
405    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
406    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
407      a set of consecutive levels in/from a 3-D array.
408    o pkg/ptracers:
409      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
410      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
411    
412    checkpoint59j
413    o in pkgs: dic, obcs, offline, rbcs:
414      standard way to compute coeff. for time interpolation between 2 time reccords
415      which retains full precision (& make results less dependent on compiler).
416      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
417    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
418      packages instead of reading ice cover and wind speed separately
419    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
420     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
421      to allow to compile customized code before the update)
422    o cleaning-up:
423      - fix CPP instruction syntax in pkg/obcs
424      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
425        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
426      - fix some threads issue in IO parts.
427    o pkg/dic:
428      - add tons of "_d 0" (--> much better testreports !)
429       and then update outputs of tutorial_global_oce_biogeo
430    o pkg/mom_fluxform:
431      add a special version of momentum advection intended to conserve momentum
432      next to a bathymetry step or a coastline edge. (default = off = #undef)
433    o new read/write pickup version:
434      - for now, only implemented for main (mdsio) pickup file.
435      - write out only what is needed to restart; merge pickup_nh , pickup_ph
436        and main pickup together.
437      - read meta file; read only what is needed to restart; stop if a field
438        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
439        if it make sense (even if the restart is not perfect).
440      - if no meta file, assume that pickup to read corresponds exactly to
441        a pickup that would currently be written.
442      - read pickup written in the old format (until checkpoint59i) if it
443        recognizes an old meta file (no field-list).
444      - add a meta file in exp. which starts from a pickup: 2 cases:
445        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
446         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
447        b) a meta file describing the content of the associated pickup file
448         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
449    o pkg/mdsio & pkg/rw:
450      - new routine to read a meta file ; new set of routine to read
451        Multiple-fields file (with meta file).
452    o added open boundary conditions capability for seaice
453        HSNOW, HSALT, UICE, and VICE
454    
455    checkpoint59i
456    o adjoint:
457      * fix multiDimAdvection adjoint
458        (partial recomputation problem by TAF for fVerT(:,:,kDown)
459        and comlev1 size definition (maxpass vs. max. number of tracers)
460      * verification/global_ocean.90x45x15 adjoint now tests
461        NLFS and multiDimAdvection using DST3 (=30)
462      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
463    o pkg/kpp: add "_d 0" to real constant (if missing);
464      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
465      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
466    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
467      for internal parameters related to restart process (formerly from PARAMS.h)
468      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
469    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
470      as argument. (only atm2d & obcs write_pickup have not yet been updated)
471    o pkg/monitor:
472      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
473      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
474      - account for deep Atmosphere factor and density factor (anelastic)
475    o added open boundary conditions capability for seaice HEFF and AREA
476    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
477      thermodynamics
478      - requires a little reorganization, which affects the testreport results
479        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
480        so that now the conservative form is tested
481      - add a few comments
482    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
483    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
484    o add new diagnostics to seaice: advective, diffusive fluxes (only for
485      multidim-advection, for scheme 2 they are not filled) and transports,
486      thermodynamic growth rates
487    o change units of EmPmR (inside the code, + within coupling interface)
488      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
489      Affects results @ truncation level (cg2d match) and update output of
490       experiments: lab_sea(6), global_ocean.90x40x15(10),
491      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
492      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
493      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
494      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
495    
496    checkpoint59h
497    o pkg/exf:
498      - improve vectorization by moving if-statement out of loops in
499        exf_mapfields, exf_radiation
500      - exf_bulkformulae.F: introduce 2D fields and vectorize code
501    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
502    o testreport:
503      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
504        monitor & update offline_exf_seaice exp. output.
505      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
506    o pkg/seaice:
507      - bug fix in the evp solver: boundary conditions were affected be
508        masking of zMax/zMin (changes results)
509      - minor bug fix in boundary conditions in seaice_calc_strainrates
510        (changes results for no_slip)
511      - seaice_lsr.F: make interpolation of eta dependent on boundaries
512      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
513      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
514        stress formulation and no-slip boundary conditions
515    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
516      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
517    o pkg/seaice: a first HSALT time stepping equation has been checked in
518    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
519      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
520      without requiring DO-IF statements
521    o pkg/thsice:
522      use continuous power-law function for partition of energy between lateral
523      melting/freezing and thinning/thickening ; old code using step function
524      still available with #undef THSICE_FRACEN_POWERLAW
525      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
526    o testreport: change AD testing : check against results/output_adm.txt
527      using same scripts as for forward test.
528    
529    checkpoint59g
530    o adjoint testing: in preparation for changing testreport:
531      - output format: cost and grad written on separated lines
532      - ad output results in directory "results" (instead of "results_ad")
533    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
534    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
535    o pkg/ecco: allow user defined cost function contributions
536    o testreport:
537      Allow to choose (per experiment) the list of tested output variables
538       and the main variable (used to issue a pass/FAIL ) ;
539      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
540      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
541      Also modify printing of summary:
542       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
543       b) echo the list of tested variables in the individual summary.txt of
544          each experiment.
545    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
546      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
547      (but still depend on the tile decompostion of the domain).
548    o pkg/seaice: change a discretization detail to make the B-grid code
549      "more symmetric". This change is likely to remove all "ridges/leads" that
550      where quasi-aligned with the grid in B-grid solutions. It may also be
551      the solution to the stress coupling issues with the B-grid.
552    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
553      remove .cvsignore from input dir. (since testreport no longer run here).
554    o pkg/thsice:
555     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
556     - fix reshaping of sea-ice just after advection:
557       melt all the ice only if ice-volume is too small.
558     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
559       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
560     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
561    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
562      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
563    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
564      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
565      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
566      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
567      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
568      -> update output.txt
569    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
570     this affects truncation error: -> update output.txt of exp:
571      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
572      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
573    
574    checkpoint59f
575    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
576    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
577      a bounded range (in forward mode)
578    o pkg/ecco, ctrl, autodiff and mom_common:
579     internal parameter controls, completements of implementations
580    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
581    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
582      (not seem any difference in testing results).
583    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
584       at face corners.
585    o pkg/generic_advdiff:
586     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
587      loop range indices for computing vertical advection tendency
588      and do the calculation in the interior only (no overlap) ;
589      for now, only implemented for SOM advection (to save CPU time).
590     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
591    o exch2 adjoint
592      First set of changes:
593      - add exch2 hand-written adjoint templates
594      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
595        This will require cleanup in pkg/autodiff/*.F
596        (changed routines currently kept separate in verif. code/)
597      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
598        that used to hide exch2 or cubed-sphere specific code
599        (commented via 'cph-exch2')
600    o pkg/seaice
601      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
602    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
603       output of global_ocean.cs32x15.thsice .
604    
605    checkpoint59e
606    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
607      for B-grid vector (not yet tested) and C-grid vector (<- only used
608      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
609    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
610      (#ifdef ALLOW_SALT_PLUME)
611    o gather_2d/scatter_2d: removed halo regions
612    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
613      scheme and the corresponding test case (under front_relax dir). For now,
614      only available with Skew-flux form and not yet tested in realistic set-up.
615      adjoint: store directives updated, but gradient checks deteriorated,
616      so maybe GM/Redi adjoint is now broken.
617    o seaice adjoint
618      * add AREA, HEFF, HSNOW as control variable
619        (should not change lab_sea results)
620      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
621    o pkg/seaice:
622      * added computation of saltFlux in seaice_growth;
623        For time being, sea ice salinity is assumed constant
624        contribution of snow flooding to freshening of sea ice is neglected.
625        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
626        defaults to 0.0 in order to maintain backward compatibility.
627        Typical values for SEAICE_salinity are 4 to 10 g/kg.
628      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
629      * added SEAICE_availHeatFrac, which specifies fraction of surface level
630        heat content used to melt or grow ice
631      * commented out cap of HICE: it helps keep ice thinner
632      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
633      * applied OBCS T/S mask to HEFFM sea ice mask
634    
635    checkpoint59d
636    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
637     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
638     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
639    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
640     and change default value of parameter "GM_Small_Number";
641     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
642       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
643       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
644    o pkg/ecco: cost function when applying pkg/smooth to controls
645    o pkg/ctrl: add forcingPrecond run time parameter
646    o pkg/seaice:
647     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
648     - fix bug in metric terms of u-equation in LSR solver (implicit part),
649       changes verification/lab_sea
650     - rearrange implicit part of u-equation in LSR solver to make it easier to
651       read, understand, and debug. This causes changes at the truncation level.
652     - fix (serious) bug in the boundary conditions (sign error in the implicit
653       part) of the LSR solver. Changes all LSR results.
654     - fixed problem with HSNOW initialization to avoid thick snow when AREA
655       is initilized with small values - does not change lab_sea results.
656     - added HsnowFile initialization capability
657    o pkg/smooth: addition to model/src and pkg/ctrl so allow
658     initialization of pkg/smooth and application to control vector
659    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
660    o dependencies: pkg/profiles requires pkg/cal
661    o pkg/profiles:
662     - added option ALLOW_PROFILES_GENERICGRID
663         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
664         that interpolation information (grid points and coefficients) is provided
665         within the netcdf input files.
666         -> sample matlab scripts can be found in MITgcm_contrib/gael
667         that allow you to prepare netcdf input files.
668     - also modified: cleaner include statements, cleaner error print statements,
669       cleaner stops when error, and more tests of the netcdf input files consistency.
670    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
671    o pkg/seaice:
672     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
673       requires a new routine: seaice_diagnostics_fill.F
674     - make sure that seaice does not move if not forced (pressure replacement
675       method, Hibler and Ip, 1995), changes results
676     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
677     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
678       It is turned off by default (=-1.), because it changes the results.
679     - make it possible to read AREA from a file, too.
680    
681    checkpoint59c
682    o add S/R and diagnostics for oceanic mixed-layer depth
683    o move GMRedi call after all vertical mixing schemes (including KPP)
684    o pkg/thsice:
685     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
686      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
687    o pkg/obcs:
688     - bug fix for balance code
689    o pkg/seaice:
690      - allow values of SEAICE_elasticParm > 1
691      - add new parameter SEAICE_evpTauRelax as an alternative
692        to SEAICE_elasticParm
693      - make lsr boundary conditions free slip (by default), changes result
694      - add code for no slip boundary conditions for lsr
695      - set minimum of zeta to zero (and not 4e8) (changes results)
696      - add a cap on AREA after advecting AREA if seaice_growth is not called
697    o change calculation of Visbeck K:
698      - no longer depend on tapering scheme; instead, compute slope (limited
699        by GM_maxSlope). this is equivalent to what was comuted before with
700        clipping or linear tappering.
701      - fix vertical averaging (wrong by 1/2 level)
702      - leave the old version (but will not be maintained) within
703        #ifdef OLD_VISBECK_CALC / #endif
704      - update output of exp. ideal_2D_oce
705    o change error catch in calc_r_star to improve vectorization
706    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
707      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
708    o adjoint:
709      Re-organized adjoint checkpointing according to Matt Mazloff
710      (but with modifs/completions/cleanups)
711      Storing is now bundled into large arrays to optimized I/O
712      (and second step in cleanup of the_main_loop)
713    
714    checkpoint59b
715    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
716      - export/import (between ocean & coupler) fields needed for ocean DIC.
717    o pkg/seaice:
718      - get rid of three more exchanges seaice_calc_viscosities (required
719        different loop boundaries in seaice_lsr and seaice_ocean_stress)
720      - bug fix in seaice_ocean_stress (update of lab_sea required)
721      - reduce loop boundaries to necessary minimum also in seaice_evp
722      - go back to the old way of computing deltaC/Z as the adjoint likes that
723        better
724    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
725      passive tracer to an Age Tracer) + update output.txt
726    o pkg/exf:
727      - implement A-grid / C-grid selection for wind-stress input files.
728      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
729      for now, in exf_bulk_largeyeager04.F only :
730      - change implementation for case where windspeed + 2. components wind-stress
731        are read-in. AND use rhoConstFresh to convert evap.
732    o pkg/seaice:
733      - use correct EXCH_UV for wind-forcing (on A-grid).
734      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
735        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
736    o pkg/exf:
737      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
738      EXF_INTERPOLATION:
739      - merge global_with_exf/code version of exf_interp_read.F
740        to the main code ;
741      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
742        reading the file ; Important: This options needs to be defined to recover
743        previous code.
744        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
745      - no longer loose real*8 precision along the way when using exf_iprec=64.
746    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
747      - change discretisation of evp-solver in order to avoid another exchange
748        (changes lab_sea) and clean up a little
749      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
750        help the adjoint (this also changes the results slightly)
751      - add a few "_d 0" where they had been missing in seaice_evp.F
752      - cleaning up: remove unused seaice_calc_rhs.F
753    o pkg/exf: some cleaning-up:
754      - change various "constants" into runtime parameters
755      - cleaned-up Large&Yeager04 routine which should eventually
756        replace exf_bulkformulae.F (changed names of S/R and CPP)
757        and merged various ALLOW_ATM_WIND options
758     only used with thsice pkg (in thsice_get_exf.F):
759      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
760        which are used when useStabilityFct_overIce=TRUE (= the default)
761      - change default values of ice & snow emissivity and scale downward LW
762        by ice & snow emissivity.
763    o pkg/thsice:
764     fix few little problems, in thsice_calc_thickn.F:
765      - growth vertically (and not laterally) if iceFrac == iceMaskMax
766      - melt only laterally if hIce < hThinIce (as the comments say)
767      and in thsice_extend.F:
768      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
769      - start to form ice as soon as the minimum ice-volume is reachable.
770     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
771      and cpl_aim+ocn
772  o pkg/kpp  o pkg/kpp
  - remove wrong (within bi,bj loops) EXCH calls.  
  - little cleaning (add argument myThid in last position, cvs header ...)  
773   - move computation of surface related input fields to KPP into a new   - move computation of surface related input fields to KPP into a new
774     subroutine kpp_forcing_surf.F     subroutine kpp_forcing_surf.F
775     - remove wrong (within bi,bj loops) EXCH calls.
776     - little cleaning (add argument myThid in last position, cvs header ...)
777     - for now, fix conservation problem by exchanging KPPviscAz (may not
778       be the best fix)
779  o pkg/seaice  o pkg/seaice
780   - check for inconsistent evp parameter/cpp-flag combination   - check for inconsistent evp parameter/cpp-flag combination
