5      ==============================      ==============================
6    
7    o pkg/thsice:
8      - implement new sequence of calls for thsice+seaice:
9          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
10          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
11      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
12        in CPP_OPTIONS.h) to recover old sequence;
13      - update diagnostics for Intermediate State thsice diagnostics: now filled
14        just before advection (instead of just after advection in old sequence);
15      - update output of experiment offline_exf_seaice (standard test);
16      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
17        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
18    o pkg/aim_v23:
19      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
20      - use standard pkg/mdsio routines to read & write CO2 pickup file;
21      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
22      - Implement new sequence of calls for seaice advection (with thsice and
23        seaice diffusion): do ice advection after ice-Thermodynamic (previously
24        was done before); change aim_do_physics.F (split the bi,bj loops block);
25      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
26    o pkg/thsice:
27      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
28        where just seaice diffusion is used without seaice-dynamics.
29    
30    checkpoint64c (2013/01/18)
31    o pkg/seaice:
32      - add a parameter JFNKres_tFac that can replace JFNKres_t
33        (= JFNKres_tFac*JFNKresidual before JFNK solver)
34      - add a line search option to the JFNK solver
35      - move update of u/vIce and computation of initial residual into a separate
36        routine (same file); makes the code a little easier to read (?)
37      - the line search requires computation of the residual and for some reason
38        I cannot do the update of u/vIce at the beginning of the Newton loop
39        without changing the results, so we move computation of the new residual
40        also to the end of the Newton loop, even without the line search
41    o pkg/mdsio:
42      - write missing value (corresponding to undefined array value) to meta files;
43        skip this if missing value is one (UNSET_RL would be a better value for the
44        case of undefined missing value but it's current the default missing-value);
45        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
46    o pkg/exf & thsice:
47      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
48        diagnostics) even when SHORTWAVE_HEATING is #undef;
49    o verification/cfc_example:
50      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
51        illustrate how to use it).
52    o verification/offline_exf_seaice:
53      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
54        files to only one time-record.
55      in input.thermo: narrow the 2 bands of low initial ice-concentration near
56        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
57        snapshot output; same mcPheePiston value as in thsice with
58        surf-current=0.2m/s.
59      in input.thsice: similar set-up as in input.thermo (channel with same seaice
60        initial conditions).
61    o verification/cfc_example:
62      - update file "data" with more standard choice (default rotationPeriod,
63        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
64        set deltaTFreeSurf to deltaTtracer) and update the output.
65    o pkg/layers:
66      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
67      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
68    o verification/offline_exf_seaice:
69      - set all {field}period to zero for constant-in-time forcing (not tested
70        anywhere else).
71    o verification/offline_exf_seaice:
72      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
73      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
74    o model/src:
75      - implement Finite-Volume method for (hydrostatic) presure gradient
76        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
77    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
78      - In order to be compatible with the default EVP code, this requires changing
79        the EVP code around a little; and because any small change immediately
80        breaks the lab_sea.hb87 verification experiment, the reference output is
81        updated two times (each time the remaining aggrement was only 2 digits):
82        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
83        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
84        The adjoint test lab_sea.evp also needed to be updated.
85      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
86        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
87        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
88        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
89        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
90        kept obscure, because I need to test it a little more.
91    o pkg/cheapaml:
92      - fix few incorrect type (_RL/_RS) in subroutine calls.
93    o pkg/seaice:
94      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
95        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
96    o model/src:
97      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
98        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
99        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
100    o pkg/cheapaml:
101      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
102        update output of experiment cheapAML_box.
103      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
104        and set them only in one place (cheapaml_readparms.F).
105      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
106      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
107        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
108    o model/src/the_main_loop.F:
109      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
110    o pkg/seaice:
111      - remove legacy branch code.
112      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
113    o verification/*/code*/SEAICE_OPTIONS.h:
114      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
115        SEAICE_CAP_HEFF).
116    o pkg/cheapaml:
117      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
118        to load new forcing fields.
119      - add missing "_d 0" where it's needed; + some editing (improve indentation).
120      - remove switch to "-r8" compiler option (no longer needed) in verification
121        cheapAML_box, keep same output (small trucation error differences).
122    o verification/offline_exf_seaice:
123      - add thermodynamics only test.
124    o verification/cheapAML_box:
125      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
126        keep same output (same 14 digits for cg2d).
127      - switch on "-r8" compiler option (some numerical values are missing
128        the "_d 0") and update output (only 6 digits for cg2d were preserved).
129    
130    checkpoint64b (2012/12/24)
131    o pkg/cheapaml:
132      - remove un-used variables (Qnet,EmPmR) from pickup files.
133      - store tendency of advected variables into cheapaml pickup file
134        and fix the AB-2 restart.
135    o verification/offline_exf_seaice and lab_sea adjoint:
136      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
137      - switch to 4 time steps in offline, consistent with lab_sea.
138      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
139      - update results after change of experiment seaice.
140    o pkg/seaice:
141      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
142        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
143        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
144        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
145    o model/src:
146      - add run-time parameter to select CG2D solver minimum-residual solution
147        (in case of a poor convergence).
148  o pkg/seaice/seaice_lsr.F  o pkg/seaice/seaice_lsr.F
149      - move calculation of matrix coefficients into new
150        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
151        file; the main purpose of this change is to be able to reuse the code
152        in S/R SEAICE_PRECONDITIONER
153    - modify the computation of the residual so that the mass of sea-ice    - modify the computation of the residual so that the mass of sea-ice
154      is not used twice; this simplyfies the calculations, but since      is not used twice; this simplifies the calculations, but since
155      the residual is never used except when LSR_mixIniGuess.ge.4---and this is      the residual is never used except when LSR_mixIniGuess.ge.4---and this is
