4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o CG2D: use pre-computed solver main-diagonal (stored in common block);
8  o moved ptracer ctrl index 17 -> 32    this affects truncation error ; generate new output file for exp. which
9      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
10        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
11        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
12        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
13        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
14        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
15    o start implementation of deep-atmosphere and anelastic formulation
16    o verification: remove 2nd copy of input files and use script "prepare_run"
17      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
18    o mom_common/vecinv/fluxform: fix a few initialisation isssues
19    o profiles: fix for multithreaded case
20    
21    o diagnostics: rename few diags:
22      s/'PRESSURE'/'RCENTER '/g
23      s/'TICE    '/'oceFreez'/g
24      s/'TAUX    '/'oceTAUX '/g
25      s/'TAUY    '/'oceTAUY '/g
26      s/'SWFLUX  '/'oceQsw  '/g
27      s/DIFx/DFxE/g
28      s/DIFy/DFyE/g
29      and add few ocean-forcing diagnostics:
30      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
31    o modifications to pkg/seaice/growth.F and budget.F, which change results of
32      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
33      as actual snow thickness.  It now refers everywhere to effective snow
34      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
35    
36    checkpoint58r_post
37    o modifications to pkg/seaice/growth.F, which change results of
38      lab_sea experiment: fixes pertain to melting snow over open water, to
39      masking EVAP under sea ice, and to using the correct AREA variable for
40      computations of EVAP, PRECIP, HSNOW, and GHEFF
41    o add ability to read bathy, salt, and theta using MNC (off by def)
42    o add flooding algorithm and advection of HSNOW for pkg/seaice;
43      both are turned off by default and do no change any results
44    o seaice advection with pkg/thsice: a step toward the use of non-linear
45      advection scheme, but #ifdef or commented out for now (requires more EXCH).
46    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
47      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
48      in natl_box (affects results @ truncation level: update output.txt)
49    o multi-threading and IO:
50      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
51      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
52        (needed to work with SingleCpuIO): tested in all verif. exp.
53    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
54      affects the results (but none of the verification test uses this scheme).
55    o Adding some pkg/diagnostics capability to pkg/seaice
56      (will certainly be subject to changes)
57    o ctrl: adding new control variables:
58      lwflux, lwdown, evap, snowprecip, apressure, runoff
59    
60    checkpoint58q_post
61    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
62      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
63      high_res_cube configuration by 4% on Columbia.
64    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
65      add (in global_with_exf/code) a version of EXF_INTERP_READ without
66      dynamical allocation (seems to work in multi-threaded).
67    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
68      single CPU io) so that TAF does not have to see EESUPPORT.h
69    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
70    
71    checkpoint58p_post
72    o obcs: stop if obcs is used with useCDscheme = .true.
73    o shelfice:
74     - fix a sign error so that no slip at shelfice interface works
75     - remove stop for combination non-hydrostatic code and shelfice. That does
76       not mean, that the results are correct, but at least they are numerically
77       stable
78    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
79    o added adjoint exch routined for all exch*3d* routines
80      and updated flow directives
81    
82    checkpoint58o_post
83    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
84      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
85    o change controling S/R for writing pickup file (new S/R do_write_pickup)
86      and clean-up reading/writing of pickup files.
87    o fix local version of read/write pickup (NH part) in rotating_tank/code
88    o simplify EXCH interface:
89     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
90     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
91    o added the regrid package
92    o shelfice:
93     - add a simple boundary layer scheme to reduce noise
94     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
95    
96    checkpoint58n_post
97    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
98       local variable (not in common block).
99    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
100      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
101      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
102        to work with SingleCpuIO.
103    o add "_d 0" to real constant of pkg/cfc subroutines ;
104       update exp. cfc_exemple & tutorial_cfc_offline output files.
105    o multi-threading and IO:
106      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
107        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
108      - barrier before and after reading.
109      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
110      - avoid using MDS_WRITELOCAL for LAND pkg output.
111      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
112        common-block variables ; Allows multi-threading with master-thread IO.
113    o change default MAX_NO_THREADS from 32 to 4 ;
114      and stop cleanly when MAX_NO_THREADS is too small.
115    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
116    
117    checkpoint58m_post
118    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
119       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
120    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
121       keep global_ocean.90x40x15 (for AD testing) with former secondary test
122       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
123    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
124        add MITgcm_tutorials (= code + all the tutorials)
125    o ecco, option to compute cost for total ssh (mean+anom)
126    o consistent with addition of ptracer and ssh in pkg/profiles
127    o profiles: adding ptracer and ssh
128    o testreport: change multi-test output-file name
129      (from output.txt.{name} to output.{name}.txt)
130    o profiles: now ok for mutli-tiles case
131    o seaice: add 4 parameters for different advection schemes for area,
132      (effective) seaice thickness, enthalphy, and snow height. Their default
133      is the standard parameter SEAICEadvScheme
134    o calc_gw:
135     - add cosFacU in zonal viscous flux (harmonic.visc.).
136     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
137       of tutorial_plume_on_slope.
138    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
139    o calc_gw: true flux-form, account for horizontal grid spacing.
140      update rotating_tank results, but not plume_on_slope (affected at
141      truncation level, 11 digits).
142    
143    checkpoint58l_post
144    o calc_gw:
145     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
146     - remove side-drag for now (need to fix it); update plume_on_slope results.
147     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
148    o commit code to make SST/SSS weights spatially variable
149      (based on either variable in-situ or variable initial T/S weights)
150    o pkg/ecco:
151      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
152        now based on horizontally varying weights wthetaLev, wsaltLev
153      * cost_averagesflags now returns year indices in addition to day, month
154      * sflux balance is performed on annual basis
155        (sflxumm, sfluxmm2, bal_sfluxmm)
156      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
157        including separate counting and multipliers
158    o pkg/rbcs
159      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
160    
161    checkpoint58k_post
162    o testreport:
163     - always build in dir. "build" (if not there, mkdir build instead of building
164       & running in input)
165     - run in dir run (if it exists), in build otherwise.
166     - call prepare_run (if input/prepare_run exists)
167     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
168    o pkg/exf modifications to interpolation and rotation routines for more
169       reasonable treatment of North Pole singularity: for tracers North Pole
170       value is set to northernmost zonal-mean value, for zonal velocity it is
171       set to zero, and for meridional velocity it is set to northernmost value.
172    o pkg/exf/exf_check_range.F
173     - add tile index to diagnostics and move stop statement to the very
174       end of the routine.
175    o pkg/diagnostics: (diagnostics_main_init.F)
176      define title of isomorphic variables according to the current config.
177    o pkg/thsice with pkg/seaice dynamics:
178    - fix domain of computation (interior only, required for exf) and do exchanges
179    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
180    o towards a standard way of dealing with multi-threading in MONITOR
181      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
182    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
183       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
184    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
185    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
186    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
187       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
188    o tracer advection:
189     - clean-up and simplify calc_common_factors.F
190     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
191       advection subroutine (but still not used within DST advection S/R)
192    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
193    
194    checkpoint58j_post
195    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
196      from file (collects calls previously in FORWARD_STEP)
197    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
198    o adjoint store dir. adjusted accordingly
199    o genmake2
200      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
201    
202    checkpoint58i_post
203    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
204      on wind stress (SEAICEstressFactor defaults to 1.)
205    o Total number of Timers is finite (<=40): comment out 2 non-essential one
206      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
207    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
208      on CS-grid: no longer loosing mass.
209    o exf & curvilinear-grid: no longer modify longitude xC & xG.
210    o pkg/ggl90: fix sloppy output and fix a bug
211    o pkg/seaice: added SEAICEuseEVPpickup parameter
212      - Set to false in order to start EVP solver with
213        non-EVP pickup files when using SEAICEuseEVP
214      - fix sign error in diffusion in seaice_calc_rhs
215    
216    checkpoint58h_post
217    * Modifications for bottom topography control
218      o replace hFacC by _hFacC at various places
219      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
220      o add non-self-adjoint cg2d_nsa
221      o update autodiff support routines
222      o re-initialise hfac after ctrl_depth_ini
223      o works for 5x5 box, doesnt work for global_ocean.90x40x15
224    * Adding verification for 5x5 box (4-layer) bottom topography control
225    
226    checkpoint58g_post
227    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
228       used for mean seasonal cycle, mean diurnal cycle); add an example
229       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
230    o pkg/ggl90:
231      - add parameter (minimum surface kinetic energy)
232      - fix bug (avoiding division by zero)
233    o couple pkg/thsice to pkg/seaice:
234      - modify advection in seaice to accomodate new scalar fields to be advected
235      - only muliDimAdection scheme work with seaice/thsice
236      - mapping of thsice-variables to seaice-variables, back and forth
237      - does not break the verification experiments, but does not give the
238        desired results either
239    o pkg/seaice
240      - make (default) second order advection a bit less confusing?
241    
242    checkpoint58f_post
243    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
244      to pkg/seaice):
245      - new routines thsice_map_exf and thsice_get_exf provide the interface
246      - add an additional formal parameter to thsice_solve4temp
247    o pkg/exf:
248      - add new fields wspeed, snowprecip (to be able to couple to thsice)
249      - correct Stefan-Boltzmann constant
250      - new parameter for longwave surface emittance
251      - separate some stuff from exf_bulkformulae into new routines  
252        exf_radiation, exf_wind
253      - add new parameters and constants: longwave emissivity for ocean, ice
254        and snow, evaporation parameters over ice
255      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
256        either wind from stress or stress from wind
257    o pkg/thSIce:
258    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
259    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
260       and THSICE_CALC_THICKN
261    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
262    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
263      to make debugging easier.
264    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
265    o pkg/bulk_force:
266      - clean-up comments and parameters ;
267      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
268    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
269      generate new output for test-experiment: aim.5l_cs.thSI
270    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
271      testreport accordingly
272    
273    checkpoint58e_post
274    o SEAICE_CGRID adjoint done
275    o R_STAR adjoint implemented.
276      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
277      * need to sort out init. of h0facc, etc.
278    o Make pkg/profile fully independent of ecco,cost, etc. stuff
279      to be able to use it in pure forward.
280    
281    checkpoint58d_post
282    o upgrade simple test-experiment to tutorial example:
283     step.1: duplicate the experiment and (step.2) will remove the old copy.
284      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
285      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
286      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
287      tutorial_global_oce_biogeo    <- copy of dic_example
288      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
289      tutorial_plume_on_slope       <- copy of plume_on_slope
290      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
291      tutorial_global_oce_optim     <- empty for now (David ?)
292      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
293     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
294    o correct a sign problem in cost_scat.F
295    o obcs and ptracers: fix boundary conditions for advections schemes
296      with larger stencil
297    o thsice adjoint: start
298    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
299      completeness
300    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
301      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
302    o ptracers adjoint:
303      * avoid extensive recomputatations
304      * fix missing re-init. of gptr (missed by TAF)
305    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
306      me to turn off the excessive output to STDOUT that this package produces
307    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
308      and add those terms in Vector-Invariant formulation.
309    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
310      if the control period (xx_hfluxperiod etc) is 0
311    o in profiles pkg, clean routines and fix details
312    o in ecco pkg, reading ssh data:
313      fix problem in case the model does not start at iter0=0
314    o fix mnc-pickup/restart for ptracers
315    o new package prifiles:
316      code to compute profile-based cost by Gael Forget
317      (modifs in ecco, ctrl, autodiff)
318    o Benign bug fix in initialization (spotted by M. Mazloff) of
319      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
320    
321    checkpoint58c_post
322    o adjoint: finish NLFS adjoint and provide reference output in
323      verification/global_ocean.90x40x15/results_ad_nlfs
324    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
325      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
326      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
327      with SEAICE_CGRID defined.
328    o move calendarDumps from "data" to "data.cal" and clean-up the code
329      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
330    o add useEXF & useCAL flags (for now, set in hard-coded way)
331    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
332      (were missing in NH mode, and wrong in quasihydrostatic mode).
333      waiting for Chris updated version of calc_gw to add those CALLs.
334    o fix bug in quasihydrostatic S/R ;
335      add a test for this option: global_ocean.90x40x15.qshyd
336    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
337      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
338    o add on/off flag useOffLine for package OFFLINE
339    o seaice:
340      - modify advection so that it works also on the C-grid
341      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
342        problem in multi-tile runs with C-grid
343      - add flags for clipping ice velocities and/or masking solver forcing
344      - fix drag (ocean on ice) formulation and a bug that caused noise in the
345        C-grid solver
346      - added a few comments to seaice_diffusion.F
347      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
348        are now exclusive)
349      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
350        required re-ordering the code a little:
351       + make DAIRN global variable (defined in SEAICE)
352       + move computation of the viscosities eta and zeta into a new separate
353         routine (because I need to recompute them in seaice_ocean_stress.F)
354    
355    checkpoint58b_post
356    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
357      update output.txt of exp. aim.5l_cs.thSI
358    o various mnc cleanups and improvements:
359      + shrink lookup tables by factor of ~4
360      + better error reporting when running out of lookup space
361      + able to handle longer path/file names (up to 500 chars)
362    o adjoint:
363      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
364      - TBD: "hidden" mom_vecinv recomp. in dynamics
365    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
366     (allow to differentiate between forcing components using new integer flags:
367      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
368     and add new flag to put Dissipation tendency out of Adams-Bashforth.
369    o ecco
370      - enable trend removal from SSH anomaly obs.
371    o adjoint
372      - a fix for PmEpR when #undef EXACT_CONSERV
373      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
374      - try to fix "hidden" recomp. in forward_step for NLFS
375        (NLFS seems broken sometimes after I checked it in)
376    o seaice:
377     - add c-grid version of the dynamic solver:
378       + three new routines that are the c-grid substitute lsr, dynsolver
379         and ostres
380       + put a few fields that were local to dynsolver into global common
381         blocks, so that I can move the computation of stresses etc into
382         seaice_lsr (saves coding but may break the adjoint).
383     - replace more hardwired parameters by runtime parameters
384     - add ice masks that mask the rhs of the implicit solvers where there
385       is no ice (commented out in seaice_dynsolver, because i am not sure
386       if this works properly), eventually this should replace the clipping
387       of ice velocities in seaice_dynsolver to +/-40cm/s.
388    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
389      include it only where its needed
390    o move balancing of fluxes before the call of external_forcing_surf
391    o seaice:
392      - correct units of turning angles (now they are really in degrees)
393      - move computation of GWATX/Y out of main routine into dynsolver
394      - initialize GWATX/Y in seaice_init
395    o Apply mask on Fresh-Water flux (needed for SSH forcing).
396      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
397    o seaice: add runtime flags for turning angles (default to zero)
398    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
399      and trend from exf forcing and ctrl control adjustments
400    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
401      (since checkpoint57x_post)
402    o change the default rotation period to 86164.s = the Earth rotation
403    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
404      and based on a reference stratification. Tested within hs94.cs-32x32x5.
405    o seaice advection: add code for choosing between the default (2nd order
406      central differences) and multiDim advection schemes provided by
407      pkg/generic_advdiff
408    o seaice:
409      - removed all references to SEAICE_GRID.h fields from
410        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
411        (cubed-sphere configuration will change a little)
412      - grid computations in seaice_init are obsolete now.
413      - cleaned up code a little so that is easier to read (hopefully).
414      - added new (better?) discretizations of default advection and diffusion
415        (turn on with SEAICEuseFluxForm)
416      - replace 1 in 3d global fields by kSurface in growth.F
417      
418    checkpoint58a_post
419    o seaice:
420      - bug fix in advect.F
421    o shelfice:
422      - separate shelfice load anomaly from pload (breaks with time
423        dependent forcing), => introduce constant field shelficeLoadAnomaly.
424        Its default is 0., but it may be computed more cleverly from (unknown)
425        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
426        done offline. A good approximation of the pressure load anomaly is
427        necessary to avoid large initial adjustment processes underneath
428        deep-reaching shelfice.
429      - small fix in ISOMIP shelfice_thermodynamics
430      - add more sophisticated thermodynamics of Hellmer (1989), this is
431        now the default
432      - give a few constants more intuitive names
433    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
434      if bulk formulae are used in long integration (especially EmPmR). Turn
435      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
436      if balancePrintMean, the imbalance that is substracted is printed to
437      STDOUT.
438    o fix bug (typo) in obcs_apply_eta.F
439    o add a new package shelfice which enables us to model the circulation
440      underneath shelf-ice with draughts of hundreds of meters.
441     - works
442     - to do: + include improved thermodynamics
443              + check whether kSurfC (from model/inc/SURFACE.h) can be used
444                instead of new field kTopC
445              + can we use topoFile, Ro_surf and existing code in ini_depth.F
446                instead of new field R_shelfIce and new code in ini_depth.F
447                and ini_mask_etc.F?
448              + adjust vertical mixing schemes?
449    o seaice pkg:
450     - add a cpp-flag to include a simple formula for a salinity dependent
451       freezing point of sea water at the surface
452     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
453       meridional stresses are now different (and hopefully correct)
454    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
455       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
456       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
457    o pkg/diagnostics: add options and parameters for regional-statistics
458       diagnostics ; define regions by reading a region-mask from a file
459       (might add other options later)
460    o pkg/bulk_force:
461     - add option and parameters to use AIM surface-flux formulae.
462     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
463       others forcing fields (defined in PARM05, parameter file "data") are loaded
464       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
465     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
466     - use the right EXCH call for uwind,vwind (to work on CS-grid).
467     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
468       and parameters (note: calcWindStress replaces .NOT.readwindstress).
469     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
470    
471    checkpoint58
472    o add "--embed-source" option to genmake2 which, when the supporting
473      tools can be compiled (as determined by genmake2) will turn on the
474      embed_files package which then embeds the entire MITgcm source code
475      (*.[fFhc] + Makefile) used for the build within the executable
476      - requested by CNH but off by default
477      - adds a paltry <9MB to the mitgcmuv executable in most cases
478      - only writes the output when useEMBEDSRC in eedata is true
479    o clean up 3-dim. relaxation codes:
480      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
481      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
482      * Thanks to Tom Haine for testing!
483    
484    checkpoint57z_post
485    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
486      affects output (@ truncation level) of exp. plume_on_slope ; updated.
487    o fix the pickup behavior for obcs in combination with ptracers
488    o fix a bug in ptracers_external_fields_load
489    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
490      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
491    o transfered surface NH pressure to eta field (if exactConserv).
492    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
493         and update lab_sea output.txt file.
494    o completing 3-dim. relaxation code: additional term
495         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
496      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
497      * At compile time, in "EXF_OPTIONS.h" set
498          #define  ALLOW_CLIMTEMP_RELAXATION
499          #define  ALLOW_CLIMSALT_RELAXATION
500      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
501          tauThetaClimRelax3Dim = 15552000.0,
502          tauSaltClimRelax3Dim  = 15552000.0,
503      * 3 cases:
504          1) Use a constant-in-time 3-dim. field
505          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
506          3) Real-time relax. to time-evolving prescribed field
507    o Adding Laplacian-type smoothness constraint on
508      initial and boundary (forcing) controls (ic, bc)
509      * enable at compile-time via
510        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
511      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
512      * Absolute scale somewhat unclear so far
513      * no area weighting was included since no other cost term does so far
514    
515    checkpoint57y_post
516    First step for a NLFS adjoint
517    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
518    o new init. routines for calc_r_star, calc_surf_dr
519    o still need to deal with ini_masks_etc
520    o testreport seemed happy
521    checkpoint57y_pre
522    
523    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
524    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
525    o add new offset feature to offline pkg (plus minor cleanup)
526    o cfc fixes for final year of integration
527    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
528      be in GCHEM_OPTIONS).
529    
530    checkpoint57x_post
531    o fix testreport Pb in multiple test experiment.
532    o cleanup our namelist syntax in verification:
533      - make it more F95 standards compliant (some work still needed)
534      - allows the vast majority of our tests to work with gfortran
535    o Non-Hydrostatic:
536     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
537     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
538    o Allow to apply AB on T,S rather than on AB(gT,gS):
539     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
540     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
541       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
542     - need a "clever" read_pickup to restart from the other AB formulation
543    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
544    o remove some unused variables (reduces number of compiler warnings)
545    o adjoint
546      * Disable useVariableViscosity for adjoint for time being
547        (there are a number of extensive recomputations)
548      * Initialize certain variables needed for adjoint
549    
550    checkpoint57w_post
551    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
552                 fix the singleCpuIO RS version of MDSWRITEFIELD
553       and add a WARNING if using globalFiles=T with multi-processors.
554    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
555      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
556    o tracer advection scheme:
557      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
558       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
559       was not very convenient).
560      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
561       (further tests needed for the implicit DST & Flux-Limiter schemes).
562    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
563      and sRef for convenience, handy, when you want to initialize
564      ptracers in a large domain with a constant non-zero value. Also,
565      untangle ptracers_init.F a little.
566    
567    checkpoint57v_post
568    o change dome exp. to use variable viscosity in side-drag terms.
569    o remove all the files from the cfc_offline test since they are now
570      incorporated into tutorial_cfc_offline which has been producing
571      identical results for a few days of testing
572    o add new parameter: sideDragFactor to enable half-slip-side BC
573      and change side-drag S/R to use viscosity from mom_calc_visc
574      (can switch back by setting sideDragFactor=0.); affects results at
575      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
576       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
577    o vorticity & strain are now computed without masking, to account for
578      no-slip-side BC in variable viscosity calculation ; mask is applied
579      anyway later on, before computing advection/coriolis terms.
580    o modify exp4 to test new obcs support for reading from external files
581      and for passive tracers
582    o fix behavior of ptracers_monitor when monitor output is written to a
583      netcdf-file; still not independent of monitor.F (writes in the same
584      file).
585    o change default value of tRef (put a uniform, meaningful value for ocean
586      & atmos) and initialize sRef (was missing, as Martin mentioned).
587    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
588      to be proportional to enstrophy dissipation length.  Thus,
589       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
590      This is now consistent with Smagorinsky and with the manual.
591    
592    checkpoint57u_post
593    o OBCS and PTRACERS: add open boundary support for passive tracers
594      - either use homogenous (pseudo) v.Neumann conditions or prescribe
595        OB-values from file; this is not different from the way theta and salinity
596        are treated
597      - however, Orlanski-radiation conditions are not supported, and the model
598        will stop if you use pTracers and Orlanski at the same time.
599      - beefed up the rountine obcs_external_fields_load: now only those open
600        boundary values are overwritten with values from files for which there
601        are really files, otherwise the OB-fields remain untouched. This makes
602        it possible to use different OBs at different ends of the domain (as
603        with EXF)
604    o reduce number of exch calls in shap_filt (s2).
605    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
606      truncation level) 4/5 MLAdjust test results (11&12 digits match).
607    
608    checkpoint57t_post
609    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
610    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
611      same truncation, independent of the face number: affects affects several
612      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
613    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
614      note that biharmonic viscosity + no-slip was not tested in any experiment.
615    o fix bug in non-linear free-surf side-drag ; generate new output for
616      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
617    o make mnc honor the writeBinaryPrec flag for most kinds of output
618    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
619    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
620      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
621    o add brackets in multi-terms sum to get same truncation, independent of
622      the face number (manage to get exactly same value of gU,gV at the cs-edge)
623      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
624    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
625      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
626      a maximum grid-scale Reynolds number.  Also, changes all length calculations
627      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
628      Suggested values of viscosity parameters found in mom_calc_visc.
629      Many new viscosity diagnostics available.
630    
631    checkpoint57s_post
632    o Add clearing-house for viscosity calculations, mom_calc_visc and
633      correct numerous bugs in LeithD and Smagorinsky discretizations.  
634      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
635      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
636      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
637      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
638      The Strain-Tension form is now called with useStrainTensonVisc=.true.
639      ViscAhStrain and viscAhTension are now retired.
640    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
641    o In response to JMC's bug report, genmake2 now ignores any soft-links
642      that it finds in the *current* directory when searching for files.
643      Soft-links found in any other source directories will still work as
644      they did before.
645    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
646      a C routine to unlimit the stack size
647    o mnc-ify pkg/aim snapshot vars
648    o mnc-ify pkg/land as requested by Daniel
649    o various changes to mnc including:
650      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
651      - output can now be grouped so that all files within a group
652          change the ITER portion of their names in lock-step together
653      - can now read ("global") PER-FACE (in addition to PER-TILE) files
654          and works with both EXCH1 and EXCH2 (but needs more testing)
655      - writing works for all verification test cases w/ g77 on Linux
656    
657    checkpoint57r_post
658    o make MNC variable initialization happen earlier
659    o add diagnostics for (almost) each term of the momentum Eq.
660    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
661    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
662    o remove MINIMAL_TAVE_OUTPUT option ;
663      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
664    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
665      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
666    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
667    o add time-dependent SST, SSS control
668    o cost terms in ecco/ modularized (new cost_generic.F)
669    o cost_averages routines are modularized (new cost_averagesgeneric.F)
670    o new infrastructure for seaice model vs. obs misfits in seaice/
671      * driver from the_main_loop.F is seaice_cost_driver.F
672      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
673      * gradient check in Exp. 6a of natl_box_adjoint/
674    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
675      (see README file)
676    
677    checkpoint57q_post
678    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
679    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
680      - bug was reported by Jean-Michel and Ian Fenty
681    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
682      update exp. cpl_aim+ocn output.
683    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
684      Needed for high-res. runs with large global files
685      to be able to limit tapelev size
686    o Changed some tests for adjoint:
687      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
688      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
689      * global_ocean.90x40x15/ back to default 3-level checkpointing
690    o Modifications to enable scripted COMMON to MODULE conversion
691      * verification/OpenAD/code/ has necessary scripts and description;
692      * converts, compiles and runs successfully;
693    
694    checkpoint57p_post
695    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
696    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
697      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
698    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
699    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
700      (was already the case for dissipation with mom_vecinv,
701       and also the case for grad.PhiHyd when staggered-timeStep)
702      This will allow to put dissipation out-off the AB time-stepping.
703     Unfortunately, affects truncation error. Update output of exp. that "fails"
704      (cg2d matching number) and leave the others for later: front_relax(10),
705      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
706      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
707    
708    checkpoint57o_post
709    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
710      (2) its ready to be documented during the 20050801 DocFest
711    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
