4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V  o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
8      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
9      with ocean biogeo)
10    o pkg/flt:
11     - do some cleaning and fix the restart ;
12     - add output.txt in flt_example/results to get this pkg tested.
13    o genmake2: add an EXTENDED_SRC option and flag.
14       for now, cannot be turned on on command line (only through genmake_local)
15    o pkg/mdsio: read/write vector:
16     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
17     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
18       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
19     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
20      (drop to 4 digits matching for grad). But this test does not look very
21      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
22    
23    checkpoint61g
24    o pkg/flt:
25      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
26       + make OPTIONS file more standard.
27      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
28      - fix _BYTESWAPIO CPP-Flag
29      - standard reading of file-parameter "data.flt"
30      - fix argument list of S/R FLT_RESTART
31      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
32    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
33    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
34      a still unfixed compiler/optimization bug
35    
36    checkpoint61f
37    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
38      update results of global_ocean.cs32x15.icedyn test.
39    o move getcon.F from model/src to pkg/fizhi.
40    o pkg/exf: add parameter for extrapolation of temp up to the surface
41       and option to prevent negative evap (in bulk_largeyeager04 only).
42    o Prather Advection scheme: fix tracer conservation for divergent flow
43      (e.g., when using NonLin Free-Surface).
44    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
45    o gmredi (Visbeck-variable-K):
46     - add more parameters to Visbeck-variable-K.
47     - use a 5 points average for dSigmaR in Visbeck-K calculation
48       (more "homogenous": same stencil and same weights as in dSigmaH)
49     - update output of ideal_2D_oce experiment.
50    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
51      (#undef REAL4_IS_SLOW)
52     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
53       coordinate variable
54     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
55       (surface forcing fields), removes some of the functionality
56     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
57     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
58       probably not all: copy _RS surface flux fields to RL field before
59       calling DIAGNOSTICS_FILL
60     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
61       real*4 (CALL EXCH_*_RS) versions.
62     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
63       (generate new output).
64    
65    checkpoint61e
66    o gmredi (Visbeck-variable-K):
67      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
68      - change computation of Visbeck-K where Slope > Smax :        
69        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
70        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
71    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
72      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
73    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
74    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
75      does not become too large (to avoid precision problems in implicit-diffusion
76      solver); update ideal_2D_oce output.
77    o pkg ggl90:
78      - in ggl90_cal.F: compute only one set of visc/diff, used to
79        step forward TKE/T/S/momentum
80      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
81        have Prandlt =1)
82    o gmredi (fm07):
83      - add lower limit on Transition layer thickness + lower limit on 1/lambda
84      - allow to set few more params from data.gmredi
85    o pkg ggl90:
86          - add missing sqrt(2) factor in computation of mixing length
87            scale in ggl90_calc.F
88            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
89    
90    checkpoint61d
91    o adjoint modifs
92      - adapt to new field rhoInSitu
93      - allow to revert from StoreDynVars2D, StoreDynVars3D
94        to individual fields
95        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
96    o store 3-D (in-situ) density in commom block (DYNVARS.h)
97     - save 1 rho computation.
98     - no longer modify T & S inland when using down_slope pkg.
99    o gad_som : allow to switch to SOM advection for T & S without corresponding
100      pickup files (using new S/R: MDS_CHECK4FILE).
101    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
102      (for useSingleCpuIO to work in multi-threaded)
103    o pkg/shelfice:
104     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
105       with SHELFICEtopoFile in data.shelfice
106     - move code for reading ice shelf topography and modifying hFacC into separate
107       subroutines of the shelfice package
108     - separate initialisation of "fixed" and "variable" variables
109     - kTopC is not (yet) replaced by kSurfC, although this is possible
110    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
111    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
112      and rename:
113      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
114      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
115    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
116    
117    checkpoint61c
118    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
119      to add mass source/sink of fluid in the interior (3-D generalisation
120      of oceanic real-fresh water flux).
121    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
122    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
123    o new pkg: down_slope
124      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
125      - presently, modify T & S inland (dwnslp_calc_rho.F).
126        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
127      - implementation for ocean in P-coords not tested.
128      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
129    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
130      (to facilitate conversion of oceanic pkg to p-coordinate).
131    o change FIND_RHO to FIND_RHO_2D :
132      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
133    o new pkg: cheapaml
134    
135    checkpoint61b
136    o exch2:
137      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
138      - no longer depend on the order sequence (N,S,E,W).
139      - 3rd exchange no longer needed (tested with 24 tiles).
140      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
141      - exch_UV_A-grid readily available (but not yet tested).
142      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
143      (both are no longer needed) in exch_uv: no effect in forward run; but
144       get truncation error differences with adjoint exch.
145    o exch2:
146     - change index-bounds storage (moved from target to local tile,
147       more intuitive this way) ; rename/remove some variables.
148     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
149    
150    checkpoint61a
151    o exch2/matlab-topology-generator:
152      fix bug in index bounds for N-S internal exchange (hard to tell if this
153      had any effect on the solution).
154    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
155      is exceeded
156    o testreport: modify syntax of awk, so that it works also with
157      awk, and not only with nawk and gawk
158    
159    checkpoint61
160    o autodiff
161      Change default for TAF usage by removing argument '-nonew_arg'
162      This changes TAF subroutine argument list (ordering of active var.)
163      Omission of this flag leads to incompatibility w.r.t. TAMC
164      To restore TAMC-compatibility, need following modifs:
165      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
166      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
167      Tested TAF version is 1.9.22
168      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
169    
170    checkpoint60
171    --->>> This is the last checkpoint for which generating the adjoint
172    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
173    --->>> by default.
174    --->>> Future checkpoints will ommit this flag by default.
175    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
176    o pkg/grdchk: Add gradient check to etan0 perturbations.
177    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
178    o pkg/autodiff: more flexibility in zeroadj.
179      model/src: modifying do_oceanic_phys.F accordingly.
180    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
181    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
182      special setup of gmredi for which the adjoint is stable
183      enough for parameter optimization.
184    o bridging the gap between eddy stress and GM.
185      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
186          along with a change in CPP option (now ALLOW_EDDYPSI).
187      -> when using GM w/ GM_AdvForm:
188          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
189          is applied either in the tracer Eq. or in momentum Eq.
190          depending on data.gmredi (intro. GM_InMomAsStress).
191      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
192      The key modifications are in model/src/taueddy_external_forcing.F
193      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
194    
195    checkpoint59r
196    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
197      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
198      fix option to read coriolis(@ cell-corner) from files with CS-grid.
199    o pkg/mnc: add some attributes to standard 1D-coordinate variables
200    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
201      mass points, when using mnc for output
202      - add runtime parameter (missing_value, missing_value_int) to override
203        default (which is the value of getcon('UNDEF'))
204    o pkg/mnc: prepare mnc for the actual use of missing values with the
205      diagnostics package: small fix in mnc_cw_readwrite.template and more
206      initialisation of never used fields
207      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
208      versions
209    o pkg/thsice/thsice_ini_vars.F added default initial values so that
210      thermodynamics sea ice solver does not blow up when some initial fields
211      are missing.
212    o move from external_forcing_surf.F to ini_forcing.F
213      the p-coord. hack consisting in using pLoad to set phi0surf ;
214      update output of tutorial_global_oce_in_p (affected @ truncation level).
215    o Freshen up a bit hs94.1x64x5, notably:
216      remove rotationPeriod and tRef=5*0. (adjoint only), and add
217      exactConserv=.TRUE.
218    o pkg/generic_advdiff:
219      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
220      applies to files where Temperature & Salinity 2nd Order moments are used.
221    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
222      this uses a dynamically allocated internal state data structure
223      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
224      and requires a fortran 90 compiler
225    
226    checkpoint59q
227    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
228       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
229    o Refresh tutorial_global_oce_biogeo, notably:
230      - change bathymetry (put back seamounts in ACC, use hFacs)
231      - change EOS (POLY3 --> JMD95Z)
232      - use Bryan-Lewis vertical diffusivity
233      - use multidimensional advection
234      - remove old virtual virtual in dic pkg, now done through ptracer pkg
235      - change a couple of parameters in dic pkg
236    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
237    o pkg/obcs: change default to OBCSfixTopo = .true.,
238      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
239      - replace "debugMode" with "debugLevel .GE. debLevB"
240    o implementation of TAF directives for gchem,cfc,dic
241    o remove "exp5" (replaced by tutorial_deep_convection).
242    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
243      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
244      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
245      --> changes results in exp4, seaice_obcs
246    o tutorial_deep_convection :
247      update the set-up and increase resolution and domain size ; start
248      from pseudo initial conditions = output at t=120mn in order to see
249      something happening when running testreport.
250    o pkg/seaice: add os7mp as an advection scheme
251                  add check for advection schemes
252                  add a flag for restoring T and S underneath sea ice
253    o pkg/my82: add netcdf-support and diagnostics
254    o thsice pkg:
255      - Now hsMax limits snow height by turning it into ice following
256        flooding scheme (and now conserving energy)
257      - Slight rewriting of the formula in thsice_calc_thick.F
258      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
259      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
260    
261    checkpoint59p
262    o gchem / dic / cfc :
263      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
264      - add new parameter files: "data.dic" & "data.cfc" ;
265      - various re-arrangement in initialisation & header file ;
266      - fix tutorial_global_oce_biogeo for multi-threaded test.
267    o pkg/dic: test for "pickup_dic" file when restarting ;
268      if no pickup-file, can restart with a re-initialised pH (same as it did
269      before) providing pickupStrictlyMatch is set to False.
270    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
271      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
272    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
273      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
274    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
275     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
276       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
277    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
278       scheme to use for vorticty-term ;
279     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
280       (with default selectVortScheme, return to original discretisation)
281     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
282    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
283    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
284      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
285      also fix diagnostics VISCAHW & VISCA4W.
286    
287    checkpoint59o
288    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
289    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
290      move a few statemens out the main loop into separate loops
291    o pkg/shelfice:
292      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
293        (kg/m^2/s), does not break tests, because in verification/isomip,
294        rhoConstFresh=rhoConst (by accident)
295      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
296      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
297        new file model/src/seawater.F, so that they are available for all pkgs.
298      - convert potential temperature into in-situ temperature. This changes the
299        isomip tests => update tests
300    o add a flag writePickupAtEnd (default=true) to be able to suppress
301      writing a pickup at the last timestep
302    o tools/mpack-1.6 :
303      - disable automake (not working) and autoconf (not needed).
304      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
305        also cleaner with much less compilation warnings.
306    o pkg/profiles:
307      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
308      (for "less than 32 characters name" compiler requirement)
309    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
310      conditions that have a different sampling frequency than S/T/U/V obcs
311    o pkg/diagnostics (stats-diags):
312      - fix global Min/Max in case 1 processor get only empty tiles
313    o genmake2: replace (4 times)
314         make genmake_tc_1.o >> genmake_warnings 2>&1
315      with
316         COMM="$CC $CFLAGS -c genmake_tc_1.c"
317         echo $COMM >> genmake_warnings
318         $COMM >> genmake_warnings 2>&1
319      to make genmake2 always see the value of CC as specified in the optfile.
320    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
321      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
322      - modify verification advect_cs test to test SOM-advection on CS-grid.
323    o pkg/ctrl:
324      - Rewrite of ctrl_map_ini_ecco.F,
325        introducing a generic routine (ctrl_map_ini_gen.F).
326      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
327    
328    checkpoint59n
329    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
330      number in dedicate array "hdiag":
331      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
332        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
333      - many small changes (integer format) for large number of diagnostics
334      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
335        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
336    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
337      usingSphericalGrid, this allows to define the rotated grid coordinates
338      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
339      geographical coordinates according to the inverse of the rotation defined
340      by the Euler angles, so that Coriolis parameter and online-interpolation by
341      exf works with the geographical coordinates on XC/YC/XG/YG.
342      Naturally, this feature does not work with all packages, so some
343      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
344      profiles), because there the coordinates are assumed to be regular
345      spherical grid coordinates.
346    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
347      - introduce isopycnal diffusion coefficient control.
348    o tools/adjoint_options:
349      - additional control vector components.
350    o pkg/mnc: have mnc create marginally meaning full coordinate variables
351      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
352    o pkg/mypackage:
353      - add example of read/write pickup for state-var ;
354      - add entry points to the main code for state-vars diags & write-pickup.
355    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
356      transitions for useExfYearlyFields
357      - add new subroutine that determines the file to read from for
358        use*YearlyFields = .TRUE. and .FALSE.
359      - add a verification experiment to global_with_exf that tests
360        useExfYearlyFields with USE_EXF_INTERPOLATION defined
361    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
362      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
363      subroutines (which could be generated from a template, because they are
364      almost identical), for now they are included in obcs_prescribe_read.F for
365      simplicity
366    o pkg/exf:
367      - add a little more diagnostic to exf_interp_read (in analogy to
368        mds_read_field, can be turned off with debugLevel < debugLevA=1)
369      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
370        ugly but fast by unrolling short inner loops, inserting a unroll=8
371        directive in routine lagran, and splitting a loop and making do while the
372        outermost loop (the latter requires the intoduction of index arrays)
373    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
374    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
375      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
376    o verification/seaice_obcs: updated for restart test and latest options
377    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
378      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
379      for now this is only available for the C-grid code and also within
380      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
381    
382    checkpoint59m
383    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
384      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
385    o gad_som : fix flux output (& diagnostics) to have same units as other  
386      advection scheme fluxes (was previously multiplied by deltaT).  
387    o added verification/seaice_obcs both to test seaice open boundaries
388      and to provide an example matlab scrpt for generating them
389    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
390    o pkg/salt_plume: clean up salt_plume_frac.F to
391      remove redundancy in PlumeMethod 1 and 4
392    o pkg/kpp: added saltplume diagnostics
393    o pkg/obcs and pkg/seaice:
394      - do not set uice and vice to zero when OB*icefile are unspecified
395      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
396      - moved seaice tracer obcs after call to seaice_growth
397    o pkg/salt_plume: added various options for salt plume depth
398      criterion and for vertical distribution of the salt
399    
400    checkpoint59l
401    o pkg/ptracers: new version of ptracers pickup:
402      read meta file and write only fields which are needed to restart.
403      ( same logic as main pickup file ; also using pickupStrictlyMatch )
404    o pkg/seaice:
405      - add timescale for melting due to warm mixed layer as a means of
406        setting SEAICE_availHeatFrac more conveniently
407      - add a CPP-flag/runtime parameter check for flooding algorithm
408      - reformulated availHeat in seaice_growth.F to be independent of AREA
409    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
410      unit changes
411    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
412    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
413      SX vector computer.
414    o pkg/seaice:
415      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
416        seaice forcing fields can now be read only through pkg/exf
417      - removed some unused halos
418    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
419    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
420      or U/VICE from U/VWIND before computing U/VSTRESS
421    
422    checkpoint59k
423    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
424      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
425    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
426      all experiments pass when compile with un-initialised var. checking option.
427    o added pkg/salt_plume
428    o script to test restart (for now, in MITgcm_contrib/jmc_script)
429    o pkg/seaice: new read/write pickup version.
430      read meta file and write only fields which are needed to restart.
431      ( same logic as main pickup file ; also using pickupStrictlyMatch )
432    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
433    o lab_sea.hb87: modify the domain & update output.hb87.txt :
434      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
435      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
436      process. Fixed here by closing the domain at the Northern boundary.
437    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
438    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
439      a set of consecutive levels in/from a 3-D array.
440    o pkg/ptracers:
441      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
442      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
443    
444    checkpoint59j
445    o in pkgs: dic, obcs, offline, rbcs:
446      standard way to compute coeff. for time interpolation between 2 time reccords
447      which retains full precision (& make results less dependent on compiler).
448      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
449    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
450      packages instead of reading ice cover and wind speed separately
451    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
452     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
453      to allow to compile customized code before the update)
454    o cleaning-up:
455      - fix CPP instruction syntax in pkg/obcs
456      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
457        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
458      - fix some threads issue in IO parts.
459    o pkg/dic:
460      - add tons of "_d 0" (--> much better testreports !)
461       and then update outputs of tutorial_global_oce_biogeo
462    o pkg/mom_fluxform:
463      add a special version of momentum advection intended to conserve momentum
464      next to a bathymetry step or a coastline edge. (default = off = #undef)
465    o new read/write pickup version:
466      - for now, only implemented for main (mdsio) pickup file.
467      - write out only what is needed to restart; merge pickup_nh , pickup_ph
468        and main pickup together.
469      - read meta file; read only what is needed to restart; stop if a field
470        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
471        if it make sense (even if the restart is not perfect).
472      - if no meta file, assume that pickup to read corresponds exactly to
473        a pickup that would currently be written.
474      - read pickup written in the old format (until checkpoint59i) if it
475        recognizes an old meta file (no field-list).
476      - add a meta file in exp. which starts from a pickup: 2 cases:
477        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
478         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
479        b) a meta file describing the content of the associated pickup file
480         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
481    o pkg/mdsio & pkg/rw:
482      - new routine to read a meta file ; new set of routine to read
483        Multiple-fields file (with meta file).
484    o added open boundary conditions capability for seaice
485        HSNOW, HSALT, UICE, and VICE
486    
487    checkpoint59i
488    o adjoint:
489      * fix multiDimAdvection adjoint
490        (partial recomputation problem by TAF for fVerT(:,:,kDown)
491        and comlev1 size definition (maxpass vs. max. number of tracers)
492      * verification/global_ocean.90x45x15 adjoint now tests
493        NLFS and multiDimAdvection using DST3 (=30)
494      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
495    o pkg/kpp: add "_d 0" to real constant (if missing);
496      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
497      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
498    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
499      for internal parameters related to restart process (formerly from PARAMS.h)
500      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
501    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
502      as argument. (only atm2d & obcs write_pickup have not yet been updated)
503    o pkg/monitor:
504      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
505      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
506      - account for deep Atmosphere factor and density factor (anelastic)
507    o added open boundary conditions capability for seaice HEFF and AREA
508    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
509      thermodynamics
510      - requires a little reorganization, which affects the testreport results
511        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
512        so that now the conservative form is tested
513      - add a few comments
514    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
515    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
516    o add new diagnostics to seaice: advective, diffusive fluxes (only for
517      multidim-advection, for scheme 2 they are not filled) and transports,
518      thermodynamic growth rates
519    o change units of EmPmR (inside the code, + within coupling interface)
520      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
521      Affects results @ truncation level (cg2d match) and update output of
522       experiments: lab_sea(6), global_ocean.90x40x15(10),
523      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
524      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
525      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
526      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
527    
528    checkpoint59h
529    o pkg/exf:
530      - improve vectorization by moving if-statement out of loops in
531        exf_mapfields, exf_radiation
532      - exf_bulkformulae.F: introduce 2D fields and vectorize code
533    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
534    o testreport:
535      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
536        monitor & update offline_exf_seaice exp. output.
537      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
538    o pkg/seaice:
539      - bug fix in the evp solver: boundary conditions were affected be
540        masking of zMax/zMin (changes results)
541      - minor bug fix in boundary conditions in seaice_calc_strainrates
542        (changes results for no_slip)
543      - seaice_lsr.F: make interpolation of eta dependent on boundaries
544      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
545      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
546        stress formulation and no-slip boundary conditions
547    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
548      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
549    o pkg/seaice: a first HSALT time stepping equation has been checked in
550    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
551      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
552      without requiring DO-IF statements
553    o pkg/thsice:
554      use continuous power-law function for partition of energy between lateral
555      melting/freezing and thinning/thickening ; old code using step function
556      still available with #undef THSICE_FRACEN_POWERLAW
557      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
558    o testreport: change AD testing : check against results/output_adm.txt
559      using same scripts as for forward test.
560    
561    checkpoint59g
562    o adjoint testing: in preparation for changing testreport:
563      - output format: cost and grad written on separated lines
564      - ad output results in directory "results" (instead of "results_ad")
565    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
566    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
567    o pkg/ecco: allow user defined cost function contributions
568    o testreport:
569      Allow to choose (per experiment) the list of tested output variables
570       and the main variable (used to issue a pass/FAIL ) ;
571      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
572      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
573      Also modify printing of summary:
574       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
575       b) echo the list of tested variables in the individual summary.txt of
576          each experiment.
577    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
578      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
579      (but still depend on the tile decompostion of the domain).
580    o pkg/seaice: change a discretization detail to make the B-grid code
581      "more symmetric". This change is likely to remove all "ridges/leads" that
582      where quasi-aligned with the grid in B-grid solutions. It may also be
583      the solution to the stress coupling issues with the B-grid.
584    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
585      remove .cvsignore from input dir. (since testreport no longer run here).
586    o pkg/thsice:
587     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
588     - fix reshaping of sea-ice just after advection:
589       melt all the ice only if ice-volume is too small.
590     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
591       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
592     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
593    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
594      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
595    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
596      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
597      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
598      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
599      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
600      -> update output.txt
601    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
602     this affects truncation error: -> update output.txt of exp:
603      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
604      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
605    
606    checkpoint59f
607    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
608    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
609      a bounded range (in forward mode)
610    o pkg/ecco, ctrl, autodiff and mom_common:
611     internal parameter controls, completements of implementations
612    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
613    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
614      (not seem any difference in testing results).
615    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
616       at face corners.
617    o pkg/generic_advdiff:
618     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
619      loop range indices for computing vertical advection tendency
620      and do the calculation in the interior only (no overlap) ;
621      for now, only implemented for SOM advection (to save CPU time).
622     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
623    o exch2 adjoint
624      First set of changes:
625      - add exch2 hand-written adjoint templates
626      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
627        This will require cleanup in pkg/autodiff/*.F
628        (changed routines currently kept separate in verif. code/)
629      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
630        that used to hide exch2 or cubed-sphere specific code
631        (commented via 'cph-exch2')
632    o pkg/seaice
633      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
634    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
635       output of global_ocean.cs32x15.thsice .
636    
637    checkpoint59e
638    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
639      for B-grid vector (not yet tested) and C-grid vector (<- only used
640      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
641    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
642      (#ifdef ALLOW_SALT_PLUME)
643    o gather_2d/scatter_2d: removed halo regions
644    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
645      scheme and the corresponding test case (under front_relax dir). For now,
646      only available with Skew-flux form and not yet tested in realistic set-up.
647      adjoint: store directives updated, but gradient checks deteriorated,
648      so maybe GM/Redi adjoint is now broken.
649    o seaice adjoint
650      * add AREA, HEFF, HSNOW as control variable
651        (should not change lab_sea results)
652      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
653    o pkg/seaice:
654      * added computation of saltFlux in seaice_growth;
655        For time being, sea ice salinity is assumed constant
656        contribution of snow flooding to freshening of sea ice is neglected.
657        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
658        defaults to 0.0 in order to maintain backward compatibility.
659        Typical values for SEAICE_salinity are 4 to 10 g/kg.
660      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
661      * added SEAICE_availHeatFrac, which specifies fraction of surface level
662        heat content used to melt or grow ice
663      * commented out cap of HICE: it helps keep ice thinner
664      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
665      * applied OBCS T/S mask to HEFFM sea ice mask
666    
667    checkpoint59d
668    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
669     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
670     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
671    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
672     and change default value of parameter "GM_Small_Number";
673     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
674       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
675       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
676    o pkg/ecco: cost function when applying pkg/smooth to controls
677    o pkg/ctrl: add forcingPrecond run time parameter
678    o pkg/seaice:
679     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
680     - fix bug in metric terms of u-equation in LSR solver (implicit part),
681       changes verification/lab_sea
682     - rearrange implicit part of u-equation in LSR solver to make it easier to
683       read, understand, and debug. This causes changes at the truncation level.
684     - fix (serious) bug in the boundary conditions (sign error in the implicit
685       part) of the LSR solver. Changes all LSR results.
686     - fixed problem with HSNOW initialization to avoid thick snow when AREA
687       is initilized with small values - does not change lab_sea results.
688     - added HsnowFile initialization capability
689    o pkg/smooth: addition to model/src and pkg/ctrl so allow
690     initialization of pkg/smooth and application to control vector
691    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
692    o dependencies: pkg/profiles requires pkg/cal
693    o pkg/profiles:
694     - added option ALLOW_PROFILES_GENERICGRID
695         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
696         that interpolation information (grid points and coefficients) is provided
697         within the netcdf input files.
698         -> sample matlab scripts can be found in MITgcm_contrib/gael
699         that allow you to prepare netcdf input files.
700     - also modified: cleaner include statements, cleaner error print statements,
701       cleaner stops when error, and more tests of the netcdf input files consistency.
702    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
703    o pkg/seaice:
704     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
705       requires a new routine: seaice_diagnostics_fill.F
706     - make sure that seaice does not move if not forced (pressure replacement
707       method, Hibler and Ip, 1995), changes results
708     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
709     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
710       It is turned off by default (=-1.), because it changes the results.
711     - make it possible to read AREA from a file, too.
712    
713    checkpoint59c
714    o add S/R and diagnostics for oceanic mixed-layer depth
715    o move GMRedi call after all vertical mixing schemes (including KPP)
716    o pkg/thsice:
717     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
718      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
719    o pkg/obcs:
720     - bug fix for balance code
721    o pkg/seaice:
722      - allow values of SEAICE_elasticParm > 1
723      - add new parameter SEAICE_evpTauRelax as an alternative
724        to SEAICE_elasticParm
725      - make lsr boundary conditions free slip (by default), changes result
726      - add code for no slip boundary conditions for lsr
727      - set minimum of zeta to zero (and not 4e8) (changes results)
728      - add a cap on AREA after advecting AREA if seaice_growth is not called
729    o change calculation of Visbeck K:
730      - no longer depend on tapering scheme; instead, compute slope (limited
731        by GM_maxSlope). this is equivalent to what was comuted before with
732        clipping or linear tappering.
733      - fix vertical averaging (wrong by 1/2 level)
734      - leave the old version (but will not be maintained) within
735        #ifdef OLD_VISBECK_CALC / #endif
736      - update output of exp. ideal_2D_oce
737    o change error catch in calc_r_star to improve vectorization
738    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
739      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
740    o adjoint:
741      Re-organized adjoint checkpointing according to Matt Mazloff
742      (but with modifs/completions/cleanups)
743      Storing is now bundled into large arrays to optimized I/O
744      (and second step in cleanup of the_main_loop)
745    
746    checkpoint59b
747    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
748      - export/import (between ocean & coupler) fields needed for ocean DIC.
749    o pkg/seaice:
750      - get rid of three more exchanges seaice_calc_viscosities (required
751        different loop boundaries in seaice_lsr and seaice_ocean_stress)
752      - bug fix in seaice_ocean_stress (update of lab_sea required)
753      - reduce loop boundaries to necessary minimum also in seaice_evp
754      - go back to the old way of computing deltaC/Z as the adjoint likes that
755        better
756    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
757      passive tracer to an Age Tracer) + update output.txt
758    o pkg/exf:
759      - implement A-grid / C-grid selection for wind-stress input files.
760      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
761      for now, in exf_bulk_largeyeager04.F only :
762      - change implementation for case where windspeed + 2. components wind-stress
763        are read-in. AND use rhoConstFresh to convert evap.
764    o pkg/seaice:
765      - use correct EXCH_UV for wind-forcing (on A-grid).
766      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
767        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
768    o pkg/exf:
769      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
770      EXF_INTERPOLATION:
771      - merge global_with_exf/code version of exf_interp_read.F
772        to the main code ;
773      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
774        reading the file ; Important: This options needs to be defined to recover
775        previous code.
776        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
777      - no longer loose real*8 precision along the way when using exf_iprec=64.
778    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
779      - change discretisation of evp-solver in order to avoid another exchange
780        (changes lab_sea) and clean up a little
781      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
782        help the adjoint (this also changes the results slightly)
783      - add a few "_d 0" where they had been missing in seaice_evp.F
784      - cleaning up: remove unused seaice_calc_rhs.F
785    o pkg/exf: some cleaning-up:
786      - change various "constants" into runtime parameters
787      - cleaned-up Large&Yeager04 routine which should eventually
788        replace exf_bulkformulae.F (changed names of S/R and CPP)
789        and merged various ALLOW_ATM_WIND options
790     only used with thsice pkg (in thsice_get_exf.F):
791      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
792        which are used when useStabilityFct_overIce=TRUE (= the default)
793      - change default values of ice & snow emissivity and scale downward LW
794        by ice & snow emissivity.
795    o pkg/thsice:
796     fix few little problems, in thsice_calc_thickn.F:
797      - growth vertically (and not laterally) if iceFrac == iceMaskMax
798      - melt only laterally if hIce < hThinIce (as the comments say)
799      and in thsice_extend.F:
800      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
801      - start to form ice as soon as the minimum ice-volume is reachable.
802     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
803      and cpl_aim+ocn
804    o pkg/kpp
805     - move computation of surface related input fields to KPP into a new
806       subroutine kpp_forcing_surf.F
807     - remove wrong (within bi,bj loops) EXCH calls.
808     - little cleaning (add argument myThid in last position, cvs header ...)
809     - for now, fix conservation problem by exchanging KPPviscAz (may not
810       be the best fix)
811    o pkg/seaice
812     - check for inconsistent evp parameter/cpp-flag combination
813     - remove leftover errIO flat for obsolete name list error handling
814    o OpenAD
815     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
816    
817    checkpoint59a
818    o pkg/seaice: some parameter clarifications and a little bit of clean up
819    o pkg/thsice: rename run-time parameters:
820       himin       -> hIceMin
821       himin0      -> hThinIce
822       hihig       -> hThickIce
823       i0          -> i0swFrac
824       transCoef   -> bMeltCoef
825       frac_energy -> fracMelting
826      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
827       with default values (for now) that do not change the results.
828      remove old version of thsice vars advection in pkg/seaice.
829    o in FFIELDS.h:
830      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
831      - make pLoad & sIceLoad always available (but still only used if
832         ATMOSPHERIC_LOADING is #define).
833    o pkg/kpp: replaced _KPP_RL with _RL
834    o bug fixes for vertical diffusivity computations when both KPP and
835        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
836        are no longer updating the vertical diffusivity array
837        (passed as argument) but are (re-) setting those arrays.
838    o pkg/seaice: fix bug in evp solver, while doing that
839      - change (improve?) discretization of stress computations for both
840        cgrid-lsr and evp solver
841      - add a new routine to compute strain rates
842      - the above changes lab_sea results
843      - add no slip conditions for evp solver (off by default), lsr-version
844        may follow
845      - fix exchange for shear at Z-points (does not change lab_sea)
846      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
847        (to force the user to pick a time step since there is not "safe" way
848        of choosing it)
849      - add principal stress diagnostics
850      - rearrange fields for evp a little to avoid having to call a: too many
851        exchanges and b: exchanges for stress trensor components which we do
852        not have.
853      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
854        of evp, complete rewrite for lsr case (latter is does not yet work
855        in all cases)
856    o pkg/kpp: add code to have mixing in shelf ice caverns
857      - add myThid to all kpp routines (long overdue)
858    
859    checkpoint59
860    o pkg/exf:
861      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
862        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
863      - move exf header files from lower_case.h to UPPER_CASE.h ;
864        add missing cvs Header & Name
865      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
866      - add namelist param. selectStressGridPosition, exf_monFreq
867      - retire many _CLIM routines, and remove data.exf_clim
868        + params moved to data.exf
869        + climsst, climsss now handled by exf_set_gen, i.e.
870          climss?period=0 refers to constant field,
871          climss?period=-12 to monthly forcing
872      - split up namelists in data.exf
873    o pkg/seaice:
874      - remove seaice_exch and seaice_exch_uv
875      - remove superfluous exchange of theta
876      - add myThid to seaice_budget_ocean/ice
877      - add new interface for atmospheric wind forcing (C-grid only)
878        + new routine
879        + two new field (taux, tauy for stress over ice)
880        + removed one global field (DAIRN) for C-grid case only
881    o pkg/thsise
882      - 2nd set of modifs for thsice adjoint in conjunction with exf
883    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
884    
885    checkpoint58y_post
886    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
887      vertical diffusivity, similar to that in MOM4; turned on using
888      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
889      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
890    o Added capability for 3D specification of background vertical diffusion
891      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
892      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
893      "data" file that contains the 3D vertical diffusivity coefficients.
894    o ice dynamics (pkg/seaice) with thsice thermodynamics:
895      - add code within pkg thsice to advect & diffuse sea-ice fields
896      similar to (and will replace) what has been added in  seaice_advdiff.F,
897      but: - conserving Mass, Heat & Salt.
898           - better when using non-linear advection scheme (not yet fully tested)
899           - can also be used in atmospheric set-up (for now, only the diffusion).
900    
901    checkpoint58x_post
902    o IO option for global-file compact format:
903      - add options when generating topology (utils/exch2/matlab-topology-generator)
904      - add I/O capability (pkg/mdsio).
905      - adapt utils/matlab/rdmds.m to read this format.
906      for now long-line format not yet supported by pkg/mdsio (& exch2).
907    o shelfice: add a few diagnostics
908    
909    checkpoint58w_post
910    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
911      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
912      (and replace horiVertRatio in NH code).
913      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
914                         and tutorial_plume_on_slope (sensitive to truncation)
915    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
916      directly to drive seaice model (C-grid only)
917    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
918     - reintroduce computation of wind from stress,
919     - compute tau (in exf_bulkformulae.F) from windstress averaged to
920       mass points to avoid tau = 0
921     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
922    o rdmnc.m: make it work with "global" files created with gluemnc
923    o rdmnc.m : some improvements in dealing with singleton dimension
924      (tested on all testreport mnc output files).
925    o genmake2: disable pkg/profiles if netcdf test fails.
926    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
927    o move call to cal_readparms up to make calendar parameters/variable available
928      to all packages
929    
930    checkpoint58v_post
931    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
932      useDynP_inEos_Zc tested.
933    o pkg/exf: changes to properly interpolate/mask/scale initial fields
934    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
935      and portions thereof.  See read_cs.txt for description and examples.
936    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
937      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
938      following the great-circle arc between those 2 points.
939    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
940      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
941    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
942     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
943     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
944     - still needs work (not working with some options ; efficiency to improve)
945       and serious testing.
946     - use this scheme for temperature & salinity in 2 advection test exp.:
947       advect_xy & advect_xz, respectively.
948    
949    checkpoint58u_post
950    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
951    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
952    o testreport: add option "-skipdir" to skip some test.
953    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
954      momentum calculation.
955    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
956    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
957      remove checkpoint.F and the_correction_step.F (no longer used);
958      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
959    o add option (linFSConserveTr) to correct for tracer source/sink due to
960      Linear Free surface
961    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
962    o pkg/thsice: fix reading mnc-pickups
963    
964    checkpoint58t_post
965    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
966    o pkg/mdsio:
967     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
968       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
969       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
970     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
971     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
972       either MDS_READ_FIELD or MDS_WRITE_FIELD )
973     - new S/R (to replace MDSWRITEMETA), which allows to write more
974       informations (variable names, time ...) to meta files.
975     - modify rdmds.m to give back the meta file content.
976    o pkg/diagnostics: change vertical interpolation to be safer, and more
977       flexible (define p-levels to interpolate to in data.diagnostics);
978      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
979       diagnostic pointer.
980    o pkg/seaice: more cleaning up of seaice_growth, added many comments
981    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
982    o fix multi-category seaice:
983     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
984       SEAICE_MULTICATEGORY
985     - fix short wave heat flux
986    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
987       and allow to use EVP solver. Change forward lab_sea: test both EVP
988       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
989    o Initial check-in of lab_sea adjoint
990      (very similar to natl_box_adjoint/code_seaice)
991      * used C-grid and EVP solver
992      * used KPP, GM/Redi
993      * uses inAdExact=.TRUE.
994      * gradient checks fail for both ADM and TLM
995        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
996        f.d. gradients actually seem more problematic than ADM, TLM gradients;
997        issue is related to forward mismatch between g77 an ifort
998    o pkg/seaice: overhaul of thermodynamics
999     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1000     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1001     - move a few global fields out of SEAICE.h into seaice_growth.F and
1002       make them 2D (FICE/QNETO/ ...)
1003     - remove FO (it is the same as QNETO)
1004     - introduce a few local fields to avoid modifying external fields such
1005       as atemp, etc.
1006    
1007    checkpoint58s_post
1008    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1009      changed exf_set_gen.F so that
1010        genperiod=0 means input file is one time-constant field and
1011        genperiod=-12 means input file contains 12 monthly means
1012    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1013      this affects truncation error ; generate new output file for exp. which
1014      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1015        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1016        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1017        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1018        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1019        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1020    o start implementation of deep-atmosphere and anelastic formulation
1021    o verification: remove 2nd copy of input files and use script "prepare_run"
1022      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1023    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1024    o profiles: fix for multithreaded case
1025    
1026    o diagnostics: rename few diags:
1027      s/'PRESSURE'/'RCENTER '/g
1028      s/'TICE    '/'oceFreez'/g
1029      s/'TAUX    '/'oceTAUX '/g
1030      s/'TAUY    '/'oceTAUY '/g
1031      s/'SWFLUX  '/'oceQsw  '/g
1032      s/DIFx/DFxE/g
1033      s/DIFy/DFyE/g
1034      and add few ocean-forcing diagnostics:
1035      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1036    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1037      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1038      as actual snow thickness.  It now refers everywhere to effective snow
1039      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1040    
1041    checkpoint58r_post
1042    o modifications to pkg/seaice/growth.F, which change results of
1043      lab_sea experiment: fixes pertain to melting snow over open water, to
1044      masking EVAP under sea ice, and to using the correct AREA variable for
1045      computations of EVAP, PRECIP, HSNOW, and GHEFF
1046    o add ability to read bathy, salt, and theta using MNC (off by def)
1047    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1048      both are turned off by default and do no change any results
1049    o seaice advection with pkg/thsice: a step toward the use of non-linear
1050      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1051    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1052      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1053      in natl_box (affects results @ truncation level: update output.txt)
1054    o multi-threading and IO:
1055      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1056      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1057        (needed to work with SingleCpuIO): tested in all verif. exp.
1058    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1059      affects the results (but none of the verification test uses this scheme).
1060    o Adding some pkg/diagnostics capability to pkg/seaice
1061      (will certainly be subject to changes)
1062    o ctrl: adding new control variables:
1063      lwflux, lwdown, evap, snowprecip, apressure, runoff
1064    
1065    checkpoint58q_post
1066    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1067      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1068      high_res_cube configuration by 4% on Columbia.
1069    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1070      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1071      dynamical allocation (seems to work in multi-threaded).
1072    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1073      single CPU io) so that TAF does not have to see EESUPPORT.h
1074    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1075    
1076    checkpoint58p_post
1077    o obcs: stop if obcs is used with useCDscheme = .true.
1078    o shelfice:
1079     - fix a sign error so that no slip at shelfice interface works
1080     - remove stop for combination non-hydrostatic code and shelfice. That does
1081       not mean, that the results are correct, but at least they are numerically
1082       stable
1083    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1084    o added adjoint exch routined for all exch*3d* routines
1085      and updated flow directives
1086    
1087    checkpoint58o_post
1088    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1089      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1090    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1091      and clean-up reading/writing of pickup files.
1092    o fix local version of read/write pickup (NH part) in rotating_tank/code
1093    o simplify EXCH interface:
1094     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1095     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1096    o added the regrid package
1097    o shelfice:
1098     - add a simple boundary layer scheme to reduce noise
1099     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1100    
1101    checkpoint58n_post
1102    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1103       local variable (not in common block).
1104    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1105      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1106      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1107        to work with SingleCpuIO.
1108    o add "_d 0" to real constant of pkg/cfc subroutines ;
1109       update exp. cfc_exemple & tutorial_cfc_offline output files.
1110    o multi-threading and IO:
1111      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1112        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1113      - barrier before and after reading.
1114      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1115      - avoid using MDS_WRITELOCAL for LAND pkg output.
1116      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1117        common-block variables ; Allows multi-threading with master-thread IO.
1118    o change default MAX_NO_THREADS from 32 to 4 ;
1119      and stop cleanly when MAX_NO_THREADS is too small.
1120    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1121    
1122    checkpoint58m_post
1123    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1124       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1125    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1126       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1127       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1128    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1129        add MITgcm_tutorials (= code + all the tutorials)
1130    o ecco, option to compute cost for total ssh (mean+anom)
1131    o consistent with addition of ptracer and ssh in pkg/profiles
1132    o profiles: adding ptracer and ssh
1133    o testreport: change multi-test output-file name
1134      (from output.txt.{name} to output.{name}.txt)
1135    o profiles: now ok for mutli-tiles case
1136    o seaice: add 4 parameters for different advection schemes for area,
1137      (effective) seaice thickness, enthalphy, and snow height. Their default
1138      is the standard parameter SEAICEadvScheme
1139    o calc_gw:
1140     - add cosFacU in zonal viscous flux (harmonic.visc.).
1141     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1142       of tutorial_plume_on_slope.
1143    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1144    o calc_gw: true flux-form, account for horizontal grid spacing.
1145      update rotating_tank results, but not plume_on_slope (affected at
1146      truncation level, 11 digits).
1147    
1148    checkpoint58l_post
1149    o calc_gw:
1150     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1151     - remove side-drag for now (need to fix it); update plume_on_slope results.
1152     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
