5      ==============================      ==============================
6    
7    o pkg/seaice: sort out emissivity and long wave radiation step 2:
8      - add emissivity for snow and ice as new run-time parameters
9        (unfortunately) that default to the corresponding exf values; this
10        changes results in most verification experiments so that for backward
11        compatibility these parameter have to be set explicitly to inconsistent
12        values (ugly);
13      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
14        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
15        until we agree how to handle this bug properly
16    o pkg/exf (interpolation):
17      - add a set of run-time param ({inputfield}_interpMethod), one for
18        each interpolated input field, to select the interpolation method
19        with a value of zero switching off the interpolation;
20      - print interpolation parameters to standard output;
21      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
22        (to use instead runoff_interpMethod=0 in data.exf).
23      - simplify default setting of interpolation parameters (for all fields,
24        set position to match model grid cell-center position, leading to trivial
25        interpolation in case of regular Lat-Lon grid) and fix for the case of
26        non-uniform delY.
27    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
28       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
29       this factor is absolutely required, because the lw exitance (= out-going
30       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
31       where the reflectivity rho = 1-emissivity for conservation reasons. Once
32       this is established, we can remove the CPP-Flag (if we want to).
33    o pkg/seaice:
34      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
35        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
36      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
37        what the name implies (and not emissivity*BoltzmannConstant), this means
38        the old default value of 5.5e-8 now means
39        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
40        S/R exf_readparms
41      - FV-discretization of the B-grid LSOR solver, turn on with
42        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
43        of the calling routine dynsolver, so that B and C-grid code look a
44        little more alike.
45      - fix index bugs in ostres.F (B-grid code)
46    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
47    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
48      default for SEAICE_emissivity, if useEXF; requires setting a wrong
49      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
50      backward compatiblity
51    o model/src: use sigmaR in calc_ivdc
52    
53    checkpoint63g (2011/12/16)
54    o pkg/seaice/seaice_growth.F:
55      fix heat conservation of the coupled ocean-seaice system.
56      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
57      solid vs liquid water treatment is resolved via QNET.
58    o pkg/seaice/seaice_growth.F:
59      add missing term for sublimation in saltFlux, which was breaking conservation.
60    o pkg/seaice/seaice_model.F:
61      Remove this patholigical case treatment in evolution branch,
62      where it is un-necessary and breaks conservation.
63      Update global_ocean.cs32x15/results accordingly for
64      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
65    o model/src:
66      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
67      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
68    o pkg/obcs:
69      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
70      tendency for temperature and salinity that is then applied to update
71      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
72      horizontal advection and diffusion contributions on the boundary (in
73      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
74      removing the mask in S/R timestep_tracer. The advantage of this approach is
75      that the updated tracer values include contributions from the surface
76      forcing and vertical diffusion.
77      This modification changes exp4.stevens because of vertical diffusion.
78    o model/src:
79      change non-curvilinear grid setting to also work with exch2 + blank tiles:
80      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
81        face dimensions.
82      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
83        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
84        and INI_SPHERICAL_POLAR_GRID.
85      change test-experiment global_ocean.90x40x15:
86      - split the domain in many more tiles (9x4 tiles of 10x10 each);
87      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
88      - update results of both test (std & dwnslp).
89    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
90       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
91    o model/src:
92      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
93        and fix initialisation when using sigma-coords.
94    o model/src:
95     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
96       to their current value at the beginning of forward_step.F": add a new run-time
97       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
98     - set doResetHFactors=T in the following test exp:
99        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
100        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
101        and tutorial_global_oce_in_p (nonLinFS in p)
102    o pkg/ecco
103      - added IES cost term
104    o verification/advect_xz
105      - scale down the depth by 1/100 (from 200 km to just 2.km)
106      - add secondary test using divergent flow, r-star and implicit vertical advection.
107      - add note (check_conserve_TS.txt) and matlab script to check global
108        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
109    o pkg/rbcs:
110      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
111    o pkg/obcs (Stevens BCs):
112      - fix various problems in the phase speed computations of the Stevens
113        boundary conditions:
114        - sign error for western and southern boundaries,
115        - time tendencies were underestimated by factor of dTracerLev and some just
116          zero (for multidim advection schemes) -> now estimate time tendencies
117          from difference between previous (n) time level and the one before (n-1);
118          this requires storing a field per tracer per boundary, also in the pickup
119          files.
120        - replace deltaTmom in cflMer/Zon computation with dTracerLev
121        - set default phase velocity to cflMer/Zon
122      - update verification experiment exp4.stevens
123    o pkg/generic_advdiff (implicit_r):
124      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
125        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
126      - fix implicit vertical diffusion or advection with NonLin FreeSurf
127        (was using current recip_hFacC instead of future recip_hFacC): set future
128        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
129        solver S/R ;
130      - fill diagnostics of vertical advective fluxes (computed from tendency)
131        when using implicit vert. advection;
132      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
133         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
134         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
135         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
136    o pkg/diagnostics:
137      - add diags for T & S tendency which goes through Adams-Bashforth.
138    
139    checkpoint63f (2011/11/30)
140    o pkg/obcs/obcs_calc_stevens.F:
141      - join some loops to reduce number of if-statements
142      - fix a bug in code for northern and southern boundaries.
143    o pkg/seaice/seaice_init_varia.F
144      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
145        caused zero ice-velocities for the B-grid code
146    o pkg/seaice/seaice_init_fixed.F
147      - fix a bug in the initialisation of the second metric terms
148        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
149      - this affects all seaice configurations with useCurviLinearGrid = .true.
150        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
151        = .true. (default)
152      - the only verification experiment affected is global_ocean.cs32x15:
153        icedyn, seaice, and seaice_dynmix (AD)
154    o pkg/thsice/thsice_diagnostics_state.F
155      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
156        not contain garbage that can lead to surprises in diagstats_calc.F
157    o model/src:
158      - move bi,bj loops inside INTEGR_CONTINUITY ;
159      - call INTEGR_CONTINUITY directly from forward_step.F
160        (previously called from momentum_correction_step.F)
161      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
162        forward_step.F and pkg/ecco/the_main_loop.F
163  o model/src/do_oceanic_phys.F:  o model/src/do_oceanic_phys.F:
164    - reset addMass to zero only if useICEFRONT ;    - reset addMass to zero only if useICEFRONT ;
165    - separated k-loop for rhoInSitu calculation ;    - separated k-loop for rhoInSitu calculation ;
