4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
8  o moved ptracer ctrl index 17 -> 32  o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
9    o add new offset feature to offline pkg (plus minor cleanup)
10    o cfc fixes for final year of integration
11    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
12      be in GCHEM_OPTIONS).
13    
14    checkpoint57x_post
15    o fix testreport Pb in multiple test experiment.
16    o cleanup our namelist syntax in verification:
17      - make it more F95 standards compliant (some work still needed)
18      - allows the vast majority of our tests to work with gfortran
19    o Non-Hydrostatic:
20     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
21     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
22    o Allow to apply AB on T,S rather than on AB(gT,gS):
23     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
24     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
25       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
26     - need a "clever" read_pickup to restart from the other AB formulation
27    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
28    o remove some unused variables (reduces number of compiler warnings)
29    o adjoint
30      * Disable useVariableViscosity for adjoint for time being
31        (there are a number of extensive recomputations)
32      * Initialize certain variables needed for adjoint
33    
34    checkpoint57w_post
35    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
36                 fix the singleCpuIO RS version of MDSWRITEFIELD
37       and add a WARNING if using globalFiles=T with multi-processors.
38    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
39      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
40    o tracer advection scheme:
41      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
42       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
43       was not very convenient).
44      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
45       (further tests needed for the implicit DST & Flux-Limiter schemes).
46    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
47      and sRef for convenience, handy, when you want to initialize
48      ptracers in a large domain with a constant non-zero value. Also,
49      untangle ptracers_init.F a little.
50    
51    checkpoint57v_post
52    o change dome exp. to use variable viscosity in side-drag terms.
53    o remove all the files from the cfc_offline test since they are now
54      incorporated into tutorial_cfc_offline which has been producing
55      identical results for a few days of testing
56    o add new parameter: sideDragFactor to enable half-slip-side BC
57      and change side-drag S/R to use viscosity from mom_calc_visc
58      (can switch back by setting sideDragFactor=0.); affects results at
59      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
60       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
61    o vorticity & strain are now computed without masking, to account for
62      no-slip-side BC in variable viscosity calculation ; mask is applied
63      anyway later on, before computing advection/coriolis terms.
64    o modify exp4 to test new obcs support for reading from external files
65      and for passive tracers
66    o fix behavior of ptracers_monitor when monitor output is written to a
67      netcdf-file; still not independent of monitor.F (writes in the same
68      file).
69    o change default value of tRef (put a uniform, meaningful value for ocean
70      & atmos) and initialize sRef (was missing, as Martin mentioned).
71    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
72      to be proportional to enstrophy dissipation length.  Thus,
73       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
74      This is now consistent with Smagorinsky and with the manual.
75    
76    checkpoint57u_post
77    o OBCS and PTRACERS: add open boundary support for passive tracers
78      - either use homogenous (pseudo) v.Neumann conditions or prescribe
79        OB-values from file; this is not different from the way theta and salinity
80        are treated
81      - however, Orlanski-radiation conditions are not supported, and the model
82        will stop if you use pTracers and Orlanski at the same time.
83      - beefed up the rountine obcs_external_fields_load: now only those open
84        boundary values are overwritten with values from files for which there
85        are really files, otherwise the OB-fields remain untouched. This makes
86        it possible to use different OBs at different ends of the domain (as
87        with EXF)
88    o reduce number of exch calls in shap_filt (s2).
89    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
90      truncation level) 4/5 MLAdjust test results (11&12 digits match).
91    
92    checkpoint57t_post
93    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
94    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
95      same truncation, independent of the face number: affects affects several
96      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
97    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
98      note that biharmonic viscosity + no-slip was not tested in any experiment.
99    o fix bug in non-linear free-surf side-drag ; generate new output for
100      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
101    o make mnc honor the writeBinaryPrec flag for most kinds of output
102    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
103    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
104      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
105    o add brackets in multi-terms sum to get same truncation, independent of
106      the face number (manage to get exactly same value of gU,gV at the cs-edge)
107      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
108    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
109      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
110      a maximum grid-scale Reynolds number.  Also, changes all length calculations
111      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
112      Suggested values of viscosity parameters found in mom_calc_visc.
113      Many new viscosity diagnostics available.
114    
115    checkpoint57s_post
116    o Add clearing-house for viscosity calculations, mom_calc_visc and
117      correct numerous bugs in LeithD and Smagorinsky discretizations.  
118      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
119      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
120      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
121      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
122      The Strain-Tension form is now called with useStrainTensonVisc=.true.
123      ViscAhStrain and viscAhTension are now retired.
124    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
125    o In response to JMC's bug report, genmake2 now ignores any soft-links
126      that it finds in the *current* directory when searching for files.
127      Soft-links found in any other source directories will still work as
128      they did before.
129    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
130      a C routine to unlimit the stack size
131    o mnc-ify pkg/aim snapshot vars
132    o mnc-ify pkg/land as requested by Daniel
133    o various changes to mnc including:
134      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
135      - output can now be grouped so that all files within a group
136          change the ITER portion of their names in lock-step together
137      - can now read ("global") PER-FACE (in addition to PER-TILE) files
138          and works with both EXCH1 and EXCH2 (but needs more testing)
139      - writing works for all verification test cases w/ g77 on Linux
140    
141    checkpoint57r_post
142    o make MNC variable initialization happen earlier
143    o add diagnostics for (almost) each term of the momentum Eq.
144    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
145    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
146    o remove MINIMAL_TAVE_OUTPUT option ;
147      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
148    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
149      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
150    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
151    o add time-dependent SST, SSS control
152    o cost terms in ecco/ modularized (new cost_generic.F)
153    o cost_averages routines are modularized (new cost_averagesgeneric.F)
154    o new infrastructure for seaice model vs. obs misfits in seaice/
155      * driver from the_main_loop.F is seaice_cost_driver.F
156      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
157      * gradient check in Exp. 6a of natl_box_adjoint/
158    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
159      (see README file)
160    
161    checkpoint57q_post
162    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
163    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
164      - bug was reported by Jean-Michel and Ian Fenty
165    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
166      update exp. cpl_aim+ocn output.
167    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
168      Needed for high-res. runs with large global files
169      to be able to limit tapelev size
170    o Changed some tests for adjoint:
171      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
172      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
173      * global_ocean.90x40x15/ back to default 3-level checkpointing
174    o Modifications to enable scripted COMMON to MODULE conversion
175      * verification/OpenAD/code/ has necessary scripts and description;
176      * converts, compiles and runs successfully;
177    
178    checkpoint57p_post
179    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
180    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
181      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
182    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
183    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
184      (was already the case for dissipation with mom_vecinv,
185       and also the case for grad.PhiHyd when staggered-timeStep)
186      This will allow to put dissipation out-off the AB time-stepping.
187     Unfortunately, affects truncation error. Update output of exp. that "fails"
188      (cg2d matching number) and leave the others for later: front_relax(10),
189      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
190      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
191    
192    checkpoint57o_post
193    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
194      (2) its ready to be documented during the 20050801 DocFest
195    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
196      for ideal_2D_oce and lab_sea on linux_ia32_g77
197    o set to #undef CTRL_SET_OLD_MAXCVARS_30
198      in global1x1_tot/code_seaice_adj to access indices 32, 33
199      (worth another tag)
200    
201    checkpoint57n_post
202    o adding precip control xx_precip 32
203    o adding swflux control xx_swflux 33
204    o Replacing 10 forcing penalty cost routines by 1 generic.
205    o Implementing partitioning in time-mean and variable adjustment
206      for atmos. state.
207    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
208  o in natl_box_adjoint:  o in natl_box_adjoint:
209    * updated: results_bulk/    * updated exp 1 to 10
210    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
211    o updated global1x1/*_seaice_adj/
212      to incorporate latest changes
213    o enable useSingleCpuIO for mdsio vector routines
214      (applies in particular to tapelev I/O)
215    o removed inefficient K-loop in all active_file*control*.F
216    
217  checkpoint57m_post  checkpoint57m_post
218  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)
