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