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