5      ==============================      ==============================
6    
7    o pkg/diagnostics:
8      - change default missing_value from UNSET_RL to -999.
9    o pkg/layers: improve vectorization of layers_fluxcalc.F, step 1
10      - split loops, make TatU/V 2D arrays. This along reduces the cpu time spent
11        in this routine by more than a factor of 3 on an NEC-SX8
12    o pkg/ecco:
13      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
14    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
15      - modifications for ALLOW_GENTIM2D_CONTROL
16      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
17      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
18      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
19      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
20    o model/src:
21      - account for moist thermodynamics in (dry) potential temperature equation;
22        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
23        and cpl_aim+ocn.
24      - also switch to standard compiler (gfortran, was using ifort previously)
25        for fizhi-cs experiments reference output.
26    o pkg/ctrl:
27      - 1st step toward generic time-varying control variable (2D) via CPP option
28        ALLOW_GENTIM2D_CONTROL
29      - note new namelist ctrl_nml_genarr in data.ctrl
30    o verification/global_ocean.cs32x15:
31      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
32        thsice calling sequence and update "output.icedyn.txt" output file.
33    o pkg/ptracers:
34      - from Ryan A.: code to allow to restart a tracer at regular time interval
35        specifying a reset frequency and a reset-phase (for each tracers).
36    o pkg/thsice:
37      - implement new sequence of calls for thsice+seaice:
38          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
39          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
40      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
41        in CPP_OPTIONS.h) to recover old sequence;
42      - update diagnostics for Intermediate State thsice diagnostics: now filled
43        just before advection (instead of just after advection in old sequence);
44      - update output of experiment offline_exf_seaice (standard test);
45      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
46        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
47    o pkg/aim_v23:
48      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
49      - use standard pkg/mdsio routines to read & write CO2 pickup file;
50      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
51      - Implement new sequence of calls for seaice advection (with thsice and
52        seaice diffusion): do ice advection after ice-Thermodynamic (previously
53        was done before); change aim_do_physics.F (split the bi,bj loops block);
54      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
55    o pkg/thsice:
56      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
57        where just seaice diffusion is used without seaice-dynamics.
58    
59    checkpoint64c (2013/01/18)
60    o pkg/seaice:
61      - add a parameter JFNKres_tFac that can replace JFNKres_t
62        (= JFNKres_tFac*JFNKresidual before JFNK solver)
63      - add a line search option to the JFNK solver
64      - move update of u/vIce and computation of initial residual into a separate
65        routine (same file); makes the code a little easier to read (?)
66      - the line search requires computation of the residual and for some reason
67        I cannot do the update of u/vIce at the beginning of the Newton loop
68        without changing the results, so we move computation of the new residual
69        also to the end of the Newton loop, even without the line search
70    o pkg/mdsio:
71      - write missing value (corresponding to undefined array value) to meta files;
72        skip this if missing value is one (UNSET_RL would be a better value for the
73        case of undefined missing value but it's current the default missing-value);
74        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
75    o pkg/exf & thsice:
76      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
77        diagnostics) even when SHORTWAVE_HEATING is #undef;
78    o verification/cfc_example:
79      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
80        illustrate how to use it).
81    o verification/offline_exf_seaice:
82      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
83        files to only one time-record.
84      in input.thermo: narrow the 2 bands of low initial ice-concentration near
85        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
86        snapshot output; same mcPheePiston value as in thsice with
87        surf-current=0.2m/s.
88      in input.thsice: similar set-up as in input.thermo (channel with same seaice
89        initial conditions).
90    o verification/cfc_example:
91      - update file "data" with more standard choice (default rotationPeriod,
92        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
93        set deltaTFreeSurf to deltaTtracer) and update the output.
94    o pkg/layers:
95      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
96      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
97    o verification/offline_exf_seaice:
98      - set all {field}period to zero for constant-in-time forcing (not tested
99        anywhere else).
100    o verification/offline_exf_seaice:
101      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
102      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
103    o model/src:
104      - implement Finite-Volume method for (hydrostatic) presure gradient
105        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
106    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
107      - In order to be compatible with the default EVP code, this requires changing
108        the EVP code around a little; and because any small change immediately
109        breaks the lab_sea.hb87 verification experiment, the reference output is
110        updated two times (each time the remaining aggrement was only 2 digits):
111        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
112        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
113        The adjoint test lab_sea.evp also needed to be updated.
114      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
115        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
116        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
117        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
118        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
119        kept obscure, because I need to test it a little more.
120    o pkg/cheapaml:
121      - fix few incorrect type (_RL/_RS) in subroutine calls.
122    o pkg/seaice:
123      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
124        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
125    o model/src:
126      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
127        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
128        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
129    o pkg/cheapaml:
130      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
131        update output of experiment cheapAML_box.
132      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
133        and set them only in one place (cheapaml_readparms.F).
134      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
135      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
136        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
137    o model/src/the_main_loop.F:
138      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
139    o pkg/seaice:
140      - remove legacy branch code.
141      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
142    o verification/*/code*/SEAICE_OPTIONS.h:
143      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
144        SEAICE_CAP_HEFF).
145  o pkg/cheapaml:  o pkg/cheapaml:
146    - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time    - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
147      to load new forcing fields.      to load new forcing fields.
