4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/offline:
8      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
9      - compute vertical velocity if not read from file (switch on exactConserv
10        & staggerTimeStep);
11      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
12    o verification:
13      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
14        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
15        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
16      - update output of exp. global_ocean.cs32x15.viscA4 after changing
17        grid-file angles (used here for coriolis-3d);
18      - remove (or gzip) few files not needed to run fizhi-cs experiments.
19    o pkg/exf (vertor interpolation):
20      - rotate vector component toward local grid-axis orientation using grid-angles
21        (stored in GRID.h) instead of locally computed rotation angle; keep old code
22        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
23    o pkg/seaice:
24      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
25        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
26    o pkg/PKG_OPTIONS.h files:
27      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
28        outside of the #ifdef ALLOW_THISPKG / #endif block.
29      - update verification/*/code/PKG_OPTIONS.h files.
30    o add a verification experiment (offline_exf_seaice/input.seaice) that test
31      the B-grid LSOR solver
32    o pkg/seaice: sort out emissivity and long wave radiation step 2:
33      - add emissivity for snow and ice as new run-time parameters
34        (unfortunately) that default to the corresponding exf values; this
35        changes results in most verification experiments so that for backward
36        compatibility these parameter have to be set explicitly to inconsistent
37        values (ugly);
38      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
39        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
40        until we agree how to handle this bug properly
41    o pkg/exf (interpolation):
42      - add a set of run-time param ({inputfield}_interpMethod), one for
43        each interpolated input field, to select the interpolation method
44        with a value of zero switching off the interpolation;
45      - print interpolation parameters to standard output;
46      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
47        (to use instead runoff_interpMethod=0 in data.exf).
48      - simplify default setting of interpolation parameters (for all fields,
49        set position to match model grid cell-center position, leading to trivial
50        interpolation in case of regular Lat-Lon grid) and fix for the case of
51        non-uniform delY.
52    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
53       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
54       this factor is absolutely required, because the lw exitance (= out-going
55       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
56       where the reflectivity rho = 1-emissivity for conservation reasons. Once
57       this is established, we can remove the CPP-Flag (if we want to).
58    o pkg/seaice:
59      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
60        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
61      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
62        what the name implies (and not emissivity*BoltzmannConstant), this means
63        the old default value of 5.5e-8 now means
64        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
65        S/R exf_readparms
66      - FV-discretization of the B-grid LSOR solver, turn on with
67        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
68        of the calling routine dynsolver, so that B and C-grid code look a
69        little more alike.
70      - fix index bugs in ostres.F (B-grid code)
71    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
72    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
73      default for SEAICE_emissivity, if useEXF; requires setting a wrong
74      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
75      backward compatiblity
76    o model/src: use sigmaR in calc_ivdc
77    
78    checkpoint63g (2011/12/16)
79    o pkg/seaice/seaice_growth.F:
80      fix heat conservation of the coupled ocean-seaice system.
81      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
82      solid vs liquid water treatment is resolved via QNET.
83    o pkg/seaice/seaice_growth.F:
84      add missing term for sublimation in saltFlux, which was breaking conservation.
85    o pkg/seaice/seaice_model.F:
86      Remove this patholigical case treatment in evolution branch,
87      where it is un-necessary and breaks conservation.
88      Update global_ocean.cs32x15/results accordingly for
89      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
90    o model/src:
91      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
92      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
93    o pkg/obcs:
94      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
95      tendency for temperature and salinity that is then applied to update
96      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
97      horizontal advection and diffusion contributions on the boundary (in
98      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
99      removing the mask in S/R timestep_tracer. The advantage of this approach is
100      that the updated tracer values include contributions from the surface
101      forcing and vertical diffusion.
102      This modification changes exp4.stevens because of vertical diffusion.
103    o model/src:
104      change non-curvilinear grid setting to also work with exch2 + blank tiles:
105      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
106        face dimensions.
107      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
108        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
109        and INI_SPHERICAL_POLAR_GRID.
110      change test-experiment global_ocean.90x40x15:
111      - split the domain in many more tiles (9x4 tiles of 10x10 each);
112      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
113      - update results of both test (std & dwnslp).
114    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
115       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
116    o model/src:
117      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
118        and fix initialisation when using sigma-coords.
119    o model/src:
120     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
121       to their current value at the beginning of forward_step.F": add a new run-time
122       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
123     - set doResetHFactors=T in the following test exp:
124        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
125        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
126        and tutorial_global_oce_in_p (nonLinFS in p)
127    o pkg/ecco
128      - added IES cost term
129    o verification/advect_xz
130      - scale down the depth by 1/100 (from 200 km to just 2.km)
131      - add secondary test using divergent flow, r-star and implicit vertical advection.
132      - add note (check_conserve_TS.txt) and matlab script to check global
133        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
134    o pkg/rbcs:
135      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
136    o pkg/obcs (Stevens BCs):
137      - fix various problems in the phase speed computations of the Stevens
138        boundary conditions:
139        - sign error for western and southern boundaries,
140        - time tendencies were underestimated by factor of dTracerLev and some just
141          zero (for multidim advection schemes) -> now estimate time tendencies
142          from difference between previous (n) time level and the one before (n-1);
143          this requires storing a field per tracer per boundary, also in the pickup
144          files.
145        - replace deltaTmom in cflMer/Zon computation with dTracerLev
146        - set default phase velocity to cflMer/Zon
147      - update verification experiment exp4.stevens
148    o pkg/generic_advdiff (implicit_r):
149      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
150        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
151      - fix implicit vertical diffusion or advection with NonLin FreeSurf
152        (was using current recip_hFacC instead of future recip_hFacC): set future
153        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
154        solver S/R ;
155      - fill diagnostics of vertical advective fluxes (computed from tendency)
156        when using implicit vert. advection;
157      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
158         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
159         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
160         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
161    o pkg/diagnostics:
162      - add diags for T & S tendency which goes through Adams-Bashforth.
163    
164    checkpoint63f (2011/11/30)
165    o pkg/obcs/obcs_calc_stevens.F:
166      - join some loops to reduce number of if-statements
167      - fix a bug in code for northern and southern boundaries.
168    o pkg/seaice/seaice_init_varia.F
169      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
170        caused zero ice-velocities for the B-grid code
171    o pkg/seaice/seaice_init_fixed.F
172      - fix a bug in the initialisation of the second metric terms
173        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
174      - this affects all seaice configurations with useCurviLinearGrid = .true.
175        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
176        = .true. (default)
177      - the only verification experiment affected is global_ocean.cs32x15:
178        icedyn, seaice, and seaice_dynmix (AD)
179    o pkg/thsice/thsice_diagnostics_state.F
180      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
181        not contain garbage that can lead to surprises in diagstats_calc.F
182    o model/src:
183      - move bi,bj loops inside INTEGR_CONTINUITY ;
184      - call INTEGR_CONTINUITY directly from forward_step.F
185        (previously called from momentum_correction_step.F)
186      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
187        forward_step.F and pkg/ecco/the_main_loop.F
188    o model/src/do_oceanic_phys.F:
189      - reset addMass to zero only if useICEFRONT ;
190      - separated k-loop for rhoInSitu calculation ;
191      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
192        and at constant T,S (= WdRHOdP);
193      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
194        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
195        transport of locally-referenced potential density);
196        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
197    o gluemnc:
198      - replace ncrcat with ncks when adding variables to *.glob.nc
199      - change the way variables without record dimensions are handled so that
200        files that have variables with and without record variables can be glued:
201        add a record dimension with a new unique name to be able to differentiate
202        between variable with and without a-prior record dimensions. Remove
203        this record dimension before adding the variable to the *.glob.nc file.
204        This procedure automatically works also for grid.*.nc files that do not
205        have any record dimension.
206    o verification/cpl_aim+ocn:
207      - generate new reference output on baudelaire (gfortran, mpich2) (previously
208        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
209    o pkg/obcs/obcs_calc_stevens.F:
210      - add code for northern and southern boundaries.
211      - reorder some loops to save some operations and so that drFBar can be scalar
212    o model/src:
213      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
214        truncation) and add diagnostics for Adams-Bashforth tendency increment.
215      - update test-exp. AD output:
216        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
217      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
218        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
219        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
220        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
221        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
222        tutorial_plume_on_slope.
223    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
224      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
225      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
226      does not even come with an F77 compiler anymore, this should not be
227      a limitation
228    
229    checkpoint63e (2011/11/06)
230    o pkg/seaice adjoint of LSR:
231      - substantially rework STORE dirs.
232      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
233        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
234        and only perform SOLV_MAX_FIXED adjoint iters.
235        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
236        always goes to same record, meaning that the last forward field will be
237        the one used in the adjoint - an approximation.
238      - now produces non-zero LSR-related gradients, and acceptable gradients for
239        An's zonal (x-z) test case (to be checked in)
240      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
241        (but these are screwed up by the thermodynamics in the first place);
242        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
243        output_adm.txt also reflects changes to seaice_lsr
244      - global_ocean.cs32x15:
245        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
246          (output_adm.seaice.txt was updated)
247        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
248          (output_adm.seaice_dynmix.txt)
249    o test-exp. exp4+stevens:
250      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
251    o pkg/seaice (lsr solver):
252      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
253        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
254      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
255      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
256        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
257      - compute (with new S/R) and print initial (+ free-driff sol. if available)
258        and final residual of linearised system.
259  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
260    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
261  o pkg/obcs: Stevens BCs (still only for east and west)  o pkg/obcs: Stevens BCs (still only for east and west)
262    - fix Stevens BCs by using intermediate velocities of previous    - fix Stevens BCs by using intermediate velocities of previous

265      more complicated, requires new pickup files and two new S/Rs:      more complicated, requires new pickup files and two new S/Rs:
266      obcs_copy_uv_n and obcs_save_uv_n      obcs_copy_uv_n and obcs_save_uv_n
267      keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY      keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
