4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8     - seaice_growth.F : in EVOLUTION branch, always include
9       a_QSWbyATM_cover in qnet (as it should be).
10     - verification/global_ocean.cs32x15 : update results accordingly
11       (output.seaice.txt output_adm.seaice.txt).
12    o pkg/seaice + obcs:
13     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
14       equivalent of assuming no tracer gradient outside the OB region.
15       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
16     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
17       after changes above);
18     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
19       only at OB location (instead of over a band of OLx width).
20    o pkg/seaice:
21     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
22       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
23    o pkg/obcs:
24      - split header file "OBCS.h" into 4 separated files:
25        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
26       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
27         (contain no conditional statement which depends on OBCS options).
28      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
29        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
30    o ctrl, cost, grdchk & autodiff pkgs:
31      - make options file more standard (like other {PKG}_OPTIONS.h file but
32        with AD_CONFIG.h); clean-up some of the included header files.
33    o pkg/obcs:
34      - do not mask tracer when applying OB (tracer == 0 could generate problems)
35      - apply tracer OB values to tracer field only at OB location (instead of
36        over a band of OLx width)
37      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
38      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
39        obcs_apply_tloc.F & obcs_apply_sloc.F
40    o obcs in model/src:
41      - call OBCS_APPLY_W only if NonHydrostatic.
42      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
43      - reset dEtaHdt and wVel to zero outside OB interior region ;
44      - leave tracer unchanged outside OB interior region: This has no effect
45        on the solution but just to prevent unrealistic tracer value outside OB.
46      - zero out velocity outside OB interior region: This has no effect on
47        the solution but just to prevent unrealistic velocity outside OB.
48    o obcs and non-lin free-surf:
49       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
50       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
51       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
52       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
53       update results of test-exp. exp4(nlfs).
54    o exp4 (nlfs) test-exp:
55       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
56       with NonLin-FreeSurf); update output.nlfs.txt
57    o obcs and 2d/3d solver norm:
58       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
59       and outside OB interior region (will allow to place OB further inside the
60       domain). Depending on the domain, can affects cg2d-Norm (previous
61       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
62       and cg3d-Norm (previous Norm was computed before canceling OB terms),
63       e.g. in tutorial_plume_on_slope.
64      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
65    o pkg rbcs:
66      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
67      - add capability to apply relaxation to horizontal velocity uVel & vVel.
68    o pkg/grdchk: add gradient check for control variable xx_shifwflx
69    o pkg/shelfice/shelfice_init_fixed.F
70      fix CPP-flag combinations
71    o pkg/seaice: Merge iceage code of Pierre Rampal
72      * update/change/correct ice age calculations
73      * add age updates for pathological cases
74      Probably needs more testing...
75    
76    checkpoint62x (2011/05/13)
77    o pkg/mom_vecinv:
78       high-order vorticity scheme: use interior masks (maskInW & S)
79       to zero-out (outside OB) gradient of vorticity.
80    o verification exp.:
81       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
82       hs94.128x64x5 and seaice_obcs ; update results.
83    o pkg/obcs:
84      fix bug in OBeta for YZ sections in obcs_exf_load.F
85    o pkg/ctrl, pkg/shelfice, and optim:
86      - add new control variable xx_shifwflx (fresh water flux underneath ice
87        shelves). This is almost as tedious as obcs-ctrl, because the
88        variables needs its own mask.
89      - add a cost function term that penalizes the deviation of xx_shifwflx
90        from the first guess (zero) in analogy to other control variables
91    o pkg/shelfice:
92      - start basic adjoint
93    o pkg/ctrl:
94      - remove extra 2D field "for good measure" when initializing in
95        ctrl_set_globfld_[xy/xz/yz].F
96      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
97      - improve error messages in ctrl_set_unpack_*
98    o OBC implementation in momentum:
99       use interior masks (maskInC,W & S) in momentum S/R:
100       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
101       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
102       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
103       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
104       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
105        (and also with Leith/Smagorinsky harmonic-viscosity).
106       Update output of experiment dome and exp4 (+nlfs).
107    o exp4 test-exp:
108      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
109        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
110        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
111        time-varying OB at Western-side for wVel (NonHyd); update output.
112      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
113        and biharmonic-viscosity ; also use prescribed time varying OB.
114    o pkg/obcs:
115      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
116    o model/src:
117      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
118      - initialise startTime & nIter0 with unlikely values: allows to set one
119        from the other without ambiguity.
120    o seaice_obcs test-exp.:
121      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
122    o pkg/obcs:
123      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
124        no longer needed with maskInC,W,S in pkg/generic_advdiff.
125    o pkg/seaice:
126      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
127        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
128      - fixed bug in the initialization of sea ice salinity variable HSALT
129        in seaice_init_varia.F  (removed dependence on ICE2WATR)
130    o fizhi-cs test exp.:
131       switch reference output convention for these 2 non-standard test-exp,
132        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
133          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
134       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
135    o model/inc:
136      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
137        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
138    o pkg/seaice:
139      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
140    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
141      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
142        and initial HSALT
143    
144    checkpoint62w (2011/04/26)
145    o pkg/mom_fluxform:
146      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
147      - use parameter "sideDragFactor" in no-slip BC side-drag part.
148      - update output of exp. global_ocean.90x40x15
149    o pkg/mom_vecinv:
150      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
151    o update seaice exp.:
152      use more consistent parameter values (remove "backward compatability only":
153       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
154      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
155       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
156    o update test-exp global_ocean.90x40x15:
157      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
158      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
159      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
160      o turn on zStar & viscA4 in standard set-up (dir input/)
161        and update output files: output.txt & output.dwnslp.txt
