5      ==============================      ==============================
6    
7  o pkg/seaice: fix a bug computing areaS in seaice_calc_lhs/rhs (J-J -> J-1)  o pkg/seaice:
8    that affects runs when SEAICEscaleSurfStress=.TRUE. (only for JFNK)    - change the termination criterion so that maxits (SEAICElinearIterMax)
9        has an effect
10      - unify iteration parameters for implicit solvers (JFNK and Picard)
11        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
12        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
13        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
14        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
15        SEAICEnonLinTol     replaces JFNKgamma_nonlin
16      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
17      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
18        use with SEAICEuseKrylov
19    o pkg/seaice/seaice_lsr.F
20      fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
21      relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
22      an effect.
23    o pkg/seaice: add two new parameters
24      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
25        parameter is not in any namelist)
26      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
27        a preconditioner for the non-linear Newton iteration of the JFNK
28        solver
29    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
30      affects some experiments at truncation level:
31      - global_ocean.cs32x15.icedyn (11 digits),
32      - global_ocean.cs32x15.seaice (11 digits),
33      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
34      - also update global_ocean.cs32x15 adjoint and tangent-linear results
35    o pkg/salt_plume & pkg/thsice:
36      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
37        connect salt_plume flux to ATM-OCN coupling pkgs interface:
38       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
39         export to coupler interface) even without compiling pkg/salt_plume ;
40       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
41         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
42    o pkg/dic:
43      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
44        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
45        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
46      - move also update with values from ATM-OCN Coupler in the same new S/R
47        (previously done in ocn_apply_import.F).
48    o tools/adjoint_options:
49      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
50        has been changed on Jan 14, 2016.
51    o pkg/ggl90:
52      - add alternative discretisation of vertical shear (off by default), to
53        compute the mean (@ grid-cell center) of vertical shear compon instead of
54        vertical shear of mean flow (@ grid-cell center).
55      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
56        results on adjacent faces of cubed-sphere grids; this fix the restart.
57    o pkg/atm_compon_interf:
58      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
59        pass last value, stored directly before export to CPL ;
60        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
61      - remove atmSLPr from pickup files (no longer needed for restart)
62    
63    checkpoint65s (2016/01/13)
64    o eesupp & genmake2:
65       - first check for Function ETIME and, if it fails, then check for subroutine
66         ETIME and consistent output; use the appropriate version in timers.F
67    o model/src:
68      - to check restart test, add option to apply EXCH to U,V earlier, just before
69        integr_continuity; turned off by default.
70    o pkg/dic:
71      - remove CPP option USE_ATMOSCO2 (not needed)
72    o tools/tst_2+2:
73      - try to ignore difference between +0 and -0 in binary file, causing test
74        to fail for no good reason.
75    o eesupp & genmake2:
76      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
77        but also check (in genmake2) that test runs and returns meaningful results.
78    o coupler pkgs:
79      Finish implementation of optionally-exchanged variable switches (started on
80       Nov 12) with addition of few more exchanged fields, including 2-way exchange
81       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
82       advection in OCN component; this requires sequential coupling.
83      coupler (pkg/atm_ocn_coupler):
84      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
85        routines (useful for debug).
86      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
87         flux, DIC fields) if corresponding switch is ON.
88      - add option to export RunOff to OCN (to use for DIC river input)
89      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
90      components (pkg/atm_ & ocn_compon_interf):
91      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
92        optionally exchanged fields; add a check & stop in cpl_readparms.F.
93        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
94        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
95      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
96        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
97      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
98      - hold in common block coupler optionally-exchanged variable switch
99        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
100      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
101        this is intended to replace the OCN cplFldtave.* output files (not updated
102        to contain new additional exchanged fields).
103    o pkg/dic:
104      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
105    o pkg/thsice:
106      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
107        and writing of thsice pickup files.
108    o pkg/atm_compon_interf:
109      - move all field individual export-call out of cpl_export_import_data.F
110        into new S/R ATM_EXPORT_FIELDS
111    o pkg/atm_compon_interf:
112      - store state variables (for now, only thSIce fields) just before beeing
113        exported (in cpl_export_import_data.F, like on ocean side) instead of from
114        atm_store_my_data.F like all exported fluxes.
115      - new version of pickup_cpl: write field names into meta file and read meta
116        file to find field postion in pickup. Also only write/read fields meeded for
117        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
118    o pkg/dic:
119      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
120    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
121        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
122        value can be from domain [0,1] to average between the two methods
123    o pkg/atm_phys:
124      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
125        hold fixed in time).
126    
127    checkpoint65r (2015/12/21)
128    o pkg/seaice:
129        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
130        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
131    o pkg/seaice:
132      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
133        when SEAICEscaleSurfStress=.TRUE.,
134      - apply areaW and areaS in S/R seaice_calc_lhs
135  o pkg/atm_phys:  o pkg/atm_phys:
136    - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes    - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
137      (shortwave & longwave, net & downward) and diagnostics of temp. tendency      (shortwave & longwave, net & downward) and diagnostics of temp. tendency
