4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
8      (were missing in NH mode, and wrong in quasihydrostatic mode).
9      waiting for Chris updated version of calc_gw to add those CALLs.
10    o fix bug in quasihydrostatic S/R ;
11      add a test for this option: global_ocean.90x40x15.qshyd
12    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
13      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
14    o add on/off flag useOffLine for package OFFLINE
15    o seaice:
16      - modify advection so that it works also on the C-grid
17      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
18        problem in multi-tile runs with C-grid
19      - add flags for clipping ice velocities and/or masking solver forcing
20      - fix drag (ocean on ice) formulation and a bug that caused noise in the
21        C-grid solver
22      - added a few comments to seaice_diffusion.F
23      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
24        are now exclusive)
25      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
26        required re-ordering the code a little:
27       + make DAIRN global variable (defined in SEAICE)
28       + move computation of the viscosities eta and zeta into a new separate
29         routine (because I need to recompute them in seaice_ocean_stress.F)
30    
31    checkpoint58b_post
32    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
33      update output.txt of exp. aim.5l_cs.thSI
34    o various mnc cleanups and improvements:
35      + shrink lookup tables by factor of ~4
36      + better error reporting when running out of lookup space
37      + able to handle longer path/file names (up to 500 chars)
38    o adjoint:
39      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
40      - TBD: "hidden" mom_vecinv recomp. in dynamics
41    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
42     (allow to differentiate between forcing components using new integer flags:
43      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
44     and add new flag to put Dissipation tendency out of Adams-Bashforth.
45    o ecco
46      - enable trend removal from SSH anomaly obs.
47    o adjoint
48      - a fix for PmEpR when #undef EXACT_CONSERV
49      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
50      - try to fix "hidden" recomp. in forward_step for NLFS
51        (NLFS seems broken sometimes after I checked it in)
52    o seaice:
53     - add c-grid version of the dynamic solver:
54       + three new routines that are the c-grid substitute lsr, dynsolver
55         and ostres
56       + put a few fields that were local to dynsolver into global common
57         blocks, so that I can move the computation of stresses etc into
58         seaice_lsr (saves coding but may break the adjoint).
59     - replace more hardwired parameters by runtime parameters
60     - add ice masks that mask the rhs of the implicit solvers where there
61       is no ice (commented out in seaice_dynsolver, because i am not sure
62       if this works properly), eventually this should replace the clipping
63       of ice velocities in seaice_dynsolver to +/-40cm/s.
64    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
65      include it only where its needed
66    o move balancing of fluxes before the call of external_forcing_surf
67    o seaice:
68      - correct units of turning angles (now they are really in degrees)
69      - move computation of GWATX/Y out of main routine into dynsolver
70      - initialize GWATX/Y in seaice_init
71    o Apply mask on Fresh-Water flux (needed for SSH forcing).
72      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
73    o seaice: add runtime flags for turning angles (default to zero)
74    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
75      and trend from exf forcing and ctrl control adjustments
76    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
77      (since checkpoint57x_post)
78    o change the default rotation period to 86164.s = the Earth rotation
79    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
80      and based on a reference stratification. Tested within hs94.cs-32x32x5.
81    o seaice advection: add code for choosing between the default (2nd order
82      central differences) and multiDim advection schemes provided by
83      pkg/generic_advdiff
84    o seaice:
85      - removed all references to SEAICE_GRID.h fields from
86        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
87        (cubed-sphere configuration will change a little)
88      - grid computations in seaice_init are obsolete now.
89      - cleaned up code a little so that is easier to read (hopefully).
90      - added new (better?) discretizations of default advection and diffusion
91        (turn on with SEAICEuseFluxForm)
92      - replace 1 in 3d global fields by kSurface in growth.F
93      
94    checkpoint58a_post
95    o seaice:
96      - bug fix in advect.F
97    o shelfice:
98      - separate shelfice load anomaly from pload (breaks with time
99        dependent forcing), => introduce constant field shelficeLoadAnomaly.
100        Its default is 0., but it may be computed more cleverly from (unknown)
101        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
102        done offline. A good approximation of the pressure load anomaly is
103        necessary to avoid large initial adjustment processes underneath
104        deep-reaching shelfice.
105      - small fix in ISOMIP shelfice_thermodynamics
106      - add more sophisticated thermodynamics of Hellmer (1989), this is
107        now the default
108      - give a few constants more intuitive names
109    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
110      if bulk formulae are used in long integration (especially EmPmR). Turn
111      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
112      if balancePrintMean, the imbalance that is substracted is printed to
113      STDOUT.
114    o fix bug (typo) in obcs_apply_eta.F
115    o add a new package shelfice which enables us to model the circulation
116      underneath shelf-ice with draughts of hundreds of meters.
117     - works
118     - to do: + include improved thermodynamics
119              + check whether kSurfC (from model/inc/SURFACE.h) can be used
120                instead of new field kTopC
121              + can we use topoFile, Ro_surf and existing code in ini_depth.F
122                instead of new field R_shelfIce and new code in ini_depth.F
123                and ini_mask_etc.F?
124              + adjust vertical mixing schemes?
125    o seaice pkg:
126     - add a cpp-flag to include a simple formula for a salinity dependent
127       freezing point of sea water at the surface
128     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
129       meridional stresses are now different (and hopefully correct)
130    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
131       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
132       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
133    o pkg/diagnostics: add options and parameters for regional-statistics
134       diagnostics ; define regions by reading a region-mask from a file
135       (might add other options later)
136    o pkg/bulk_force:
137     - add option and parameters to use AIM surface-flux formulae.
138     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
139       others forcing fields (defined in PARM05, parameter file "data") are loaded
140       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
141     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
142     - use the right EXCH call for uwind,vwind (to work on CS-grid).
143     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
144       and parameters (note: calcWindStress replaces .NOT.readwindstress).
145     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
146    
147    checkpoint58
148    o add "--embed-source" option to genmake2 which, when the supporting
149      tools can be compiled (as determined by genmake2) will turn on the
150      embed_files package which then embeds the entire MITgcm source code
151      (*.[fFhc] + Makefile) used for the build within the executable
152      - requested by CNH but off by default
153      - adds a paltry <9MB to the mitgcmuv executable in most cases
154      - only writes the output when useEMBEDSRC in eedata is true
155    o clean up 3-dim. relaxation codes:
156      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
157      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
158      * Thanks to Tom Haine for testing!
159    
160    checkpoint57z_post
161    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
162      affects output (@ truncation level) of exp. plume_on_slope ; updated.
163    o fix the pickup behavior for obcs in combination with ptracers
164    o fix a bug in ptracers_external_fields_load
165    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
166      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
167    o transfered surface NH pressure to eta field (if exactConserv).
168    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
169         and update lab_sea output.txt file.
170    o completing 3-dim. relaxation code: additional term
171         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
172      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
173      * At compile time, in "EXF_OPTIONS.h" set
174          #define  ALLOW_CLIMTEMP_RELAXATION
175          #define  ALLOW_CLIMSALT_RELAXATION
176      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
177          tauThetaClimRelax3Dim = 15552000.0,
178          tauSaltClimRelax3Dim  = 15552000.0,
179      * 3 cases:
180          1) Use a constant-in-time 3-dim. field
181          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
182          3) Real-time relax. to time-evolving prescribed field
183    o Adding Laplacian-type smoothness constraint on
184      initial and boundary (forcing) controls (ic, bc)
185      * enable at compile-time via
186        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
187      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
188      * Absolute scale somewhat unclear so far
189      * no area weighting was included since no other cost term does so far
190    
191    checkpoint57y_post
192    First step for a NLFS adjoint
193    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
194    o new init. routines for calc_r_star, calc_surf_dr
195    o still need to deal with ini_masks_etc
196    o testreport seemed happy
197    checkpoint57y_pre
198    
199    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
200    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
201    o add new offset feature to offline pkg (plus minor cleanup)
202    o cfc fixes for final year of integration
203    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
204      be in GCHEM_OPTIONS).
205    
206    checkpoint57x_post
207    o fix testreport Pb in multiple test experiment.
208    o cleanup our namelist syntax in verification:
209      - make it more F95 standards compliant (some work still needed)
210      - allows the vast majority of our tests to work with gfortran
211    o Non-Hydrostatic:
212     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
213     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
214    o Allow to apply AB on T,S rather than on AB(gT,gS):
215     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
216     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
217       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
218     - need a "clever" read_pickup to restart from the other AB formulation
219    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
220    o remove some unused variables (reduces number of compiler warnings)
221    o adjoint
222      * Disable useVariableViscosity for adjoint for time being
223        (there are a number of extensive recomputations)
224      * Initialize certain variables needed for adjoint
225    
226    checkpoint57w_post
227    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
228                 fix the singleCpuIO RS version of MDSWRITEFIELD
229       and add a WARNING if using globalFiles=T with multi-processors.
230    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
231      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
232    o tracer advection scheme:
233      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
234       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
235       was not very convenient).
236      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
237       (further tests needed for the implicit DST & Flux-Limiter schemes).
238    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
239      and sRef for convenience, handy, when you want to initialize
240      ptracers in a large domain with a constant non-zero value. Also,
241      untangle ptracers_init.F a little.
242    
243    checkpoint57v_post
244    o change dome exp. to use variable viscosity in side-drag terms.
245    o remove all the files from the cfc_offline test since they are now
246      incorporated into tutorial_cfc_offline which has been producing
247      identical results for a few days of testing
248    o add new parameter: sideDragFactor to enable half-slip-side BC
249      and change side-drag S/R to use viscosity from mom_calc_visc
250      (can switch back by setting sideDragFactor=0.); affects results at
251      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
252       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
253    o vorticity & strain are now computed without masking, to account for
254      no-slip-side BC in variable viscosity calculation ; mask is applied
255      anyway later on, before computing advection/coriolis terms.
256    o modify exp4 to test new obcs support for reading from external files
257      and for passive tracers
258    o fix behavior of ptracers_monitor when monitor output is written to a
259      netcdf-file; still not independent of monitor.F (writes in the same
260      file).
261    o change default value of tRef (put a uniform, meaningful value for ocean
262      & atmos) and initialize sRef (was missing, as Martin mentioned).
263    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
264      to be proportional to enstrophy dissipation length.  Thus,
265       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
266      This is now consistent with Smagorinsky and with the manual.
267    
268    checkpoint57u_post
269    o OBCS and PTRACERS: add open boundary support for passive tracers
270      - either use homogenous (pseudo) v.Neumann conditions or prescribe
271        OB-values from file; this is not different from the way theta and salinity
272        are treated
273      - however, Orlanski-radiation conditions are not supported, and the model
274        will stop if you use pTracers and Orlanski at the same time.
275      - beefed up the rountine obcs_external_fields_load: now only those open
276        boundary values are overwritten with values from files for which there
277        are really files, otherwise the OB-fields remain untouched. This makes
278        it possible to use different OBs at different ends of the domain (as
279        with EXF)
280    o reduce number of exch calls in shap_filt (s2).
281    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
282      truncation level) 4/5 MLAdjust test results (11&12 digits match).
283    
284    checkpoint57t_post
285    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
286    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
287      same truncation, independent of the face number: affects affects several
288      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
289    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
290      note that biharmonic viscosity + no-slip was not tested in any experiment.
291    o fix bug in non-linear free-surf side-drag ; generate new output for
292      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
293    o make mnc honor the writeBinaryPrec flag for most kinds of output
294    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
295    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
296      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
297    o add brackets in multi-terms sum to get same truncation, independent of
298      the face number (manage to get exactly same value of gU,gV at the cs-edge)
299      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
300    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
301      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
302      a maximum grid-scale Reynolds number.  Also, changes all length calculations
303      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
304      Suggested values of viscosity parameters found in mom_calc_visc.
305      Many new viscosity diagnostics available.
306    
307    checkpoint57s_post
308    o Add clearing-house for viscosity calculations, mom_calc_visc and
309      correct numerous bugs in LeithD and Smagorinsky discretizations.  
310      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
311      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
312      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
313      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
314      The Strain-Tension form is now called with useStrainTensonVisc=.true.
315      ViscAhStrain and viscAhTension are now retired.
316    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
317    o In response to JMC's bug report, genmake2 now ignores any soft-links
318      that it finds in the *current* directory when searching for files.
319      Soft-links found in any other source directories will still work as
320      they did before.
321    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
322      a C routine to unlimit the stack size
323    o mnc-ify pkg/aim snapshot vars
324    o mnc-ify pkg/land as requested by Daniel
325    o various changes to mnc including:
326      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
327      - output can now be grouped so that all files within a group
328          change the ITER portion of their names in lock-step together
329      - can now read ("global") PER-FACE (in addition to PER-TILE) files
330          and works with both EXCH1 and EXCH2 (but needs more testing)
331      - writing works for all verification test cases w/ g77 on Linux
332    
333    checkpoint57r_post
334    o make MNC variable initialization happen earlier
335    o add diagnostics for (almost) each term of the momentum Eq.
336    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
337    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
338    o remove MINIMAL_TAVE_OUTPUT option ;
339      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
340    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
341      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
342    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
343    o add time-dependent SST, SSS control
344    o cost terms in ecco/ modularized (new cost_generic.F)
345    o cost_averages routines are modularized (new cost_averagesgeneric.F)
346    o new infrastructure for seaice model vs. obs misfits in seaice/
347      * driver from the_main_loop.F is seaice_cost_driver.F
348      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
349      * gradient check in Exp. 6a of natl_box_adjoint/
350    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
351      (see README file)
352    
353    checkpoint57q_post
354    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
355    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
356      - bug was reported by Jean-Michel and Ian Fenty
357    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
358      update exp. cpl_aim+ocn output.
359    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
360      Needed for high-res. runs with large global files
361      to be able to limit tapelev size
362    o Changed some tests for adjoint:
363      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
364      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
365      * global_ocean.90x40x15/ back to default 3-level checkpointing
366    o Modifications to enable scripted COMMON to MODULE conversion
367      * verification/OpenAD/code/ has necessary scripts and description;
368      * converts, compiles and runs successfully;
369    
370    checkpoint57p_post
371    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
372    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
373      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
374    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
375    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
376      (was already the case for dissipation with mom_vecinv,
377       and also the case for grad.PhiHyd when staggered-timeStep)
378      This will allow to put dissipation out-off the AB time-stepping.
379     Unfortunately, affects truncation error. Update output of exp. that "fails"
380      (cg2d matching number) and leave the others for later: front_relax(10),
381      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
382      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
383    
384    checkpoint57o_post
385    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
386      (2) its ready to be documented during the 20050801 DocFest
387  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
388    for ideal_2D_oce and lab_sea on linux_ia32_g77    for ideal_2D_oce and lab_sea on linux_ia32_g77
389    o set to #undef CTRL_SET_OLD_MAXCVARS_30
390      in global1x1_tot/code_seaice_adj to access indices 32, 33
391      (worth another tag)
392    
393  checkpoint57n_post  checkpoint57n_post
394  o adding precip control xx_precip 32  o adding precip control xx_precip 32
