5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
8       SEAICE_rhoIce in the Rothrock (1975)-type strength calculations
9       (bug fix)
10    
11    o model/src:
12      - since we have several heat capacity (even in model/src), define "recip_Cp"
13        as local variable (no longer in common block) to avoid any confusion.
14      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
15    o pkg/exf:
16      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
17        air density as function of air Temp, Humidity and atm pressure.
18    
19    checkpoint64w (2014/05/02)
20    o verification:
21      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
22        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
23        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
24        affects AD gradient (down to 8-7 matching digits for global_ocean and
25        5-6 for lab_sea).
26    seaice_reg_ridge.F seaice_do_ridging.F
27    o model/src: for atmosphere in p* coords:
28      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
29      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
30        but not yet activated.
31    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
32      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
33      - this changes the results (but not for any verification experiment, because
34        none tests this), but avoids having an extra field in the restart files
35    o pkg/seaice: remove global variable TICE (not needed)
36      - replace by TICES or local variable where necessary (cost_seaice_test,
37        seaice_diagnostics_state)
38      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
39      - use specific read/write routines for reading and writing individual leves
40        of a multilevel field
41    o pkg/ctrl & model/inc:
42      - move additional anomaly fields of control vars (related to options:
43         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
44        from DYNVARS.h into new header file: CTRL_FIELDS.h
45    o pkg/seaice: some small modifications to the ridging code
46      - make fw2ObyRidge a global variable and add the freshwater flux to
47        seaice_growth
48      - pass actual thickness from seaice_prepare_ridging, so that it is
49        computed only in one place and compute it in the same way as in
50        seaice_growth
51      - initialise more fields in seaice_do_ridging that where cause floating
52        point exceptions over land
53    o pkg/seaice: preparations for ridging code and first real ridging code
54      - move most of "PART 1" of S/R seaice_growth into a new and separate
55        S/R seaice_reg_ridge that will both regularize the state variable after
56        advection call the actual ridging routine;
57      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
58        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
59      - remove ridging code from seaice_advdiff
60      - clean up remaining part 1 of seaice_growth in an attempt to make it
61        more readable (this is probably subjective)
62      - call seaice_itd_redist once in the initialisation phase to have the initial
63        conditions in the correct category
64      - finally: add new ridging routine for ITD code
65    
66    checkpoint64v (2014/04/11)
67    o pkg/ecco:
68      - add runtime parameters mdt[start,end]date[1,2]
69      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
70    o pkg/seaice:
71      - make deltaC a global variable, so that it can be used in ridging code
72      - first step towards ridging: introduce new routines that compute
73        ice strength based on ridging parameters
74      - add diagnostic for HSNOWITD
75      - add opnWtrFrac as a global variable (required for ridging scheme)
76    o pkg/salt_plume + pkg/seaice/seaice_growth.F
77      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
78        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
79    o verification/hs94.1x64x5:
80      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
81      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
82    o autodiff:
83      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
84        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
85        For now, only in pkgs used in verification/hs94.1x64x5.
86      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
87        which are specific to TAF/TAMC).
88      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
89        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
90        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
91      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
92        building mitgcmuv_ad (make adAll).
93    o pkg/ecco:
94      - cost_gencost_seaicev4.F:
95         reformulate proxy cost as function of sst and local param SEAICE_freeze
96         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
97      - add stop statement if old names siv4-[sst,vol] are used
98      - add snapshots + cost reports for atmospheric longwave
99      - remove factor 0.1 in front of wtau[u,v]
100      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
101         ALLOW_TMI_SST_COST_CONTRIBUTION
102    o pkg/atm_phys:
103      - add some diagnostics for Short-wave and for convection S/R.
104    o pkg/seaice/seaice_growth:
105      - fix a bug in the lateral melt parameterization for SEAICE_ITD
106        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
107      - rearrange loop order for better vector code in the same code block
108      - rewrite the floeDiameter formula to have fewer divisions
109      -  (miraculously) none of this changes the results of seaice_itd
110    o pkg/smooth:
111      - move param smooth2Ddiffnbt to pkg/ecco
112    o pkg/salt_plume:
113      - salt_plume_frac.F:
114         clean up local param names
115         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
116    o pkg/rw:
117      - add RS version of S/R READ_MFLDS_LEV.
118    o pkg/streamice:
119      - fix the restart test by writing/reading pickup_streamice files.
120    o pkg/seaice:
121      - refine checks for jfnk-related parameters
122      - comment out if statement with SEAICEuseIMEX parameter as long as there
123        is no IMEX code to avoid confusion and surprises

153    o pkg/ecco
154      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
155        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
156      - replace hard-coded record number and period which only work for monthly
157        with read-in runtime param that works for other periods (month,day,year)
