5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o shelfice:
8  o moved ptracer ctrl index 17 -> 32    - separate shelfice load anomaly from pload (breaks with time
9        dependent forcing), => introduce constant field shelficeLoadAnomaly.
10        Its default is 0., but it may be computed more cleverly from (unknown)
11        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
12        done offline. A good approximation of the pressure load anomaly is
13        necessary to avoid large initial adjustment processes underneath
14        deep-reaching shelfice.
15      - small fix in ISOMIP shelfice_thermodynamics
16      - add more sophisticated thermodynamics of Hellmer (1989), this is
17        now the default
18      - give a few constants more intuitive names
19    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
20      if bulk formulae are used in long integration (especially EmPmR). Turn
21      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
22      if balancePrintMean, the imbalance that is substracted is printed to
23      STDOUT.
24    o fix bug (typo) in obcs_apply_eta.F
25    o add a new package shelfice which enables us to model the circulation
26      underneath shelf-ice with draughts of hundreds of meters.
27     - works
28     - to do: + include improved thermodynamics
29              + check whether kSurfC (from model/inc/SURFACE.h) can be used
30                instead of new field kTopC
31              + can we use topoFile, Ro_surf and existing code in ini_depth.F
32                instead of new field R_shelfIce and new code in ini_depth.F
33                and ini_mask_etc.F?
34              + adjust vertical mixing schemes?
35    o seaice pkg:
36     - add a cpp-flag to include a simple formula for a salinity dependent
37       freezing point of sea water at the surface
38     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
39       meridional stresses are now different (and hopefully correct)
40    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
41       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
42       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
43    o pkg/diagnostics: add options and parameters for regional-statistics
44       diagnostics ; define regions by reading a region-mask from a file
45       (might add other options later)
46    o pkg/bulk_force:
47     - add option and parameters to use AIM surface-flux formulae.
48     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
49       others forcing fields (defined in PARM05, parameter file "data") are loaded
50       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
51     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
52     - use the right EXCH call for uwind,vwind (to work on CS-grid).
53     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
54       and parameters (note: calcWindStress replaces .NOT.readwindstress).
55     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
56    
57    checkpoint58
58    o add "--embed-source" option to genmake2 which, when the supporting
59      tools can be compiled (as determined by genmake2) will turn on the
60      embed_files package which then embeds the entire MITgcm source code
61      (*.[fFhc] + Makefile) used for the build within the executable
62      - requested by CNH but off by default
63      - adds a paltry <9MB to the mitgcmuv executable in most cases
64      - only writes the output when useEMBEDSRC in eedata is true
65    o clean up 3-dim. relaxation codes:
66      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
67      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
68      * Thanks to Tom Haine for testing!
69    
70    checkpoint57z_post
71    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
72      affects output (@ truncation level) of exp. plume_on_slope ; updated.
73    o fix the pickup behavior for obcs in combination with ptracers
74    o fix a bug in ptracers_external_fields_load
75    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
76      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
77    o transfered surface NH pressure to eta field (if exactConserv).
78    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
79         and update lab_sea output.txt file.
80    o completing 3-dim. relaxation code: additional term
81         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
82      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
83      * At compile time, in "EXF_OPTIONS.h" set
84          #define  ALLOW_CLIMTEMP_RELAXATION
85          #define  ALLOW_CLIMSALT_RELAXATION
86      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
87          tauThetaClimRelax3Dim = 15552000.0,
88          tauSaltClimRelax3Dim  = 15552000.0,
89      * 3 cases:
90          1) Use a constant-in-time 3-dim. field
91          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
92          3) Real-time relax. to time-evolving prescribed field
93    o Adding Laplacian-type smoothness constraint on
94      initial and boundary (forcing) controls (ic, bc)
95      * enable at compile-time via
96        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
97      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
98      * Absolute scale somewhat unclear so far
99      * no area weighting was included since no other cost term does so far
100    
101    checkpoint57y_post
102    First step for a NLFS adjoint
103    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
104    o new init. routines for calc_r_star, calc_surf_dr
105    o still need to deal with ini_masks_etc
106    o testreport seemed happy
107    checkpoint57y_pre
108    
109    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
110    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
111    o add new offset feature to offline pkg (plus minor cleanup)
112    o cfc fixes for final year of integration
113    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
114      be in GCHEM_OPTIONS).
115    
116    checkpoint57x_post
117    o fix testreport Pb in multiple test experiment.
118    o cleanup our namelist syntax in verification:
119      - make it more F95 standards compliant (some work still needed)
120      - allows the vast majority of our tests to work with gfortran
121    o Non-Hydrostatic:
122     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
123     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
124    o Allow to apply AB on T,S rather than on AB(gT,gS):
125     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
126     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
127       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
128     - need a "clever" read_pickup to restart from the other AB formulation
129    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
130    o remove some unused variables (reduces number of compiler warnings)
131    o adjoint
132      * Disable useVariableViscosity for adjoint for time being
133        (there are a number of extensive recomputations)
134      * Initialize certain variables needed for adjoint
135    
136    checkpoint57w_post
137    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
138                 fix the singleCpuIO RS version of MDSWRITEFIELD
139       and add a WARNING if using globalFiles=T with multi-processors.
140    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
141      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
142    o tracer advection scheme:
143      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
144       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
145       was not very convenient).
146      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
147       (further tests needed for the implicit DST & Flux-Limiter schemes).
148    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
149      and sRef for convenience, handy, when you want to initialize
150      ptracers in a large domain with a constant non-zero value. Also,
151      untangle ptracers_init.F a little.
152    
153    checkpoint57v_post
154    o change dome exp. to use variable viscosity in side-drag terms.
155    o remove all the files from the cfc_offline test since they are now
156      incorporated into tutorial_cfc_offline which has been producing
157      identical results for a few days of testing
158    o add new parameter: sideDragFactor to enable half-slip-side BC
159      and change side-drag S/R to use viscosity from mom_calc_visc
160      (can switch back by setting sideDragFactor=0.); affects results at
161      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
162       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
163    o vorticity & strain are now computed without masking, to account for
164      no-slip-side BC in variable viscosity calculation ; mask is applied
165      anyway later on, before computing advection/coriolis terms.
166    o modify exp4 to test new obcs support for reading from external files
167      and for passive tracers
168    o fix behavior of ptracers_monitor when monitor output is written to a
169      netcdf-file; still not independent of monitor.F (writes in the same
170      file).
171    o change default value of tRef (put a uniform, meaningful value for ocean
172      & atmos) and initialize sRef (was missing, as Martin mentioned).
173    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
174      to be proportional to enstrophy dissipation length.  Thus,
175       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
176      This is now consistent with Smagorinsky and with the manual.
177    
178    checkpoint57u_post
179    o OBCS and PTRACERS: add open boundary support for passive tracers
180      - either use homogenous (pseudo) v.Neumann conditions or prescribe
181        OB-values from file; this is not different from the way theta and salinity
182        are treated
183      - however, Orlanski-radiation conditions are not supported, and the model
184        will stop if you use pTracers and Orlanski at the same time.
185      - beefed up the rountine obcs_external_fields_load: now only those open
186        boundary values are overwritten with values from files for which there
187        are really files, otherwise the OB-fields remain untouched. This makes
188        it possible to use different OBs at different ends of the domain (as
189        with EXF)
190    o reduce number of exch calls in shap_filt (s2).
191    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
192      truncation level) 4/5 MLAdjust test results (11&12 digits match).
193    
194    checkpoint57t_post
195    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
196    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
197      same truncation, independent of the face number: affects affects several
198      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
199    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
200      note that biharmonic viscosity + no-slip was not tested in any experiment.
201    o fix bug in non-linear free-surf side-drag ; generate new output for
202      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
203    o make mnc honor the writeBinaryPrec flag for most kinds of output
204    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
205    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
206      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
207    o add brackets in multi-terms sum to get same truncation, independent of
208      the face number (manage to get exactly same value of gU,gV at the cs-edge)
209      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
210    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
211      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
212      a maximum grid-scale Reynolds number.  Also, changes all length calculations
213      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
214      Suggested values of viscosity parameters found in mom_calc_visc.
215      Many new viscosity diagnostics available.
216    
217    checkpoint57s_post
218    o Add clearing-house for viscosity calculations, mom_calc_visc and
219      correct numerous bugs in LeithD and Smagorinsky discretizations.  
220      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
221      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
222      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
223      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
224      The Strain-Tension form is now called with useStrainTensonVisc=.true.
225      ViscAhStrain and viscAhTension are now retired.
226    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
227    o In response to JMC's bug report, genmake2 now ignores any soft-links
228      that it finds in the *current* directory when searching for files.
229      Soft-links found in any other source directories will still work as
230      they did before.
231    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
232      a C routine to unlimit the stack size
233    o mnc-ify pkg/aim snapshot vars
234    o mnc-ify pkg/land as requested by Daniel
235    o various changes to mnc including:
236      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
237      - output can now be grouped so that all files within a group
238          change the ITER portion of their names in lock-step together
239      - can now read ("global") PER-FACE (in addition to PER-TILE) files
240          and works with both EXCH1 and EXCH2 (but needs more testing)
241      - writing works for all verification test cases w/ g77 on Linux
242    
243    checkpoint57r_post
244    o make MNC variable initialization happen earlier
245    o add diagnostics for (almost) each term of the momentum Eq.
246    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
247    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
248    o remove MINIMAL_TAVE_OUTPUT option ;
249      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
250    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
251      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
252    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
253    o add time-dependent SST, SSS control
254    o cost terms in ecco/ modularized (new cost_generic.F)
255    o cost_averages routines are modularized (new cost_averagesgeneric.F)
256    o new infrastructure for seaice model vs. obs misfits in seaice/
257      * driver from the_main_loop.F is seaice_cost_driver.F
258      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
259      * gradient check in Exp. 6a of natl_box_adjoint/
260    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
261      (see README file)
262    
263    checkpoint57q_post
264    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
265    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
266      - bug was reported by Jean-Michel and Ian Fenty
267    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
268      update exp. cpl_aim+ocn output.
269    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
270      Needed for high-res. runs with large global files
271      to be able to limit tapelev size
272    o Changed some tests for adjoint:
273      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
274      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
275      * global_ocean.90x40x15/ back to default 3-level checkpointing
276    o Modifications to enable scripted COMMON to MODULE conversion
277      * verification/OpenAD/code/ has necessary scripts and description;
278      * converts, compiles and runs successfully;
279    
280    checkpoint57p_post
281    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
282    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
283      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
284    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
285    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
286      (was already the case for dissipation with mom_vecinv,
287       and also the case for grad.PhiHyd when staggered-timeStep)
288      This will allow to put dissipation out-off the AB time-stepping.
289     Unfortunately, affects truncation error. Update output of exp. that "fails"
290      (cg2d matching number) and leave the others for later: front_relax(10),
291      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
292      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
293    
294    checkpoint57o_post
295    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
296      (2) its ready to be documented during the 20050801 DocFest
297    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
298      for ideal_2D_oce and lab_sea on linux_ia32_g77
299    o set to #undef CTRL_SET_OLD_MAXCVARS_30
300      in global1x1_tot/code_seaice_adj to access indices 32, 33
301      (worth another tag)
302    
303    checkpoint57n_post
304    o adding precip control xx_precip 32
305    o adding swflux control xx_swflux 33
306    o Replacing 10 forcing penalty cost routines by 1 generic.
307    o Implementing partitioning in time-mean and variable adjustment
308      for atmos. state.
309    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
310  o in natl_box_adjoint:  o in natl_box_adjoint:
311    * updated: results_bulk/    * updated exp 1 to 10
312    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
313    o updated global1x1/*_seaice_adj/
314      to incorporate latest changes
315    o enable useSingleCpuIO for mdsio vector routines
316      (applies in particular to tapelev I/O)
317    o removed inefficient K-loop in all active_file*control*.F
318    
319  checkpoint57m_post  checkpoint57m_post
320  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
