5      ==============================      ==============================
6    
7    o pkg/exf:
8      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
9        air density as function of air Temp, Humidity and atm pressure.
10    
11    checkpoint64w (2014/05/02)
12    o verification:
13      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
14        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
15        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
16        affects AD gradient (down to 8-7 matching digits for global_ocean and
17        5-6 for lab_sea).
18    seaice_reg_ridge.F seaice_do_ridging.F
19    o model/src: for atmosphere in p* coords:
20      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
21      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
22        but not yet activated.
23    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
24      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
25      - this changes the results (but not for any verification experiment, because
26        none tests this), but avoids having an extra field in the restart files
27    o pkg/seaice: remove global variable TICE (not needed)
28      - replace by TICES or local variable where necessary (cost_seaice_test,
29        seaice_diagnostics_state)
30      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
31      - use specific read/write routines for reading and writing individual leves
32        of a multilevel field
33    o pkg/ctrl & model/inc:
34      - move additional anomaly fields of control vars (related to options:
35         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
36        from DYNVARS.h into new header file: CTRL_FIELDS.h
37    o pkg/seaice: some small modifications to the ridging code
38      - make fw2ObyRidge a global variable and add the freshwater flux to
39        seaice_growth
40      - pass actual thickness from seaice_prepare_ridging, so that it is
41        computed only in one place and compute it in the same way as in
42        seaice_growth
43      - initialise more fields in seaice_do_ridging that where cause floating
44        point exceptions over land
45    o pkg/seaice: preparations for ridging code and first real ridging code
46      - move most of "PART 1" of S/R seaice_growth into a new and separate
47        S/R seaice_reg_ridge that will both regularize the state variable after
48        advection call the actual ridging routine;
49      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
50        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
51      - remove ridging code from seaice_advdiff
52      - clean up remaining part 1 of seaice_growth in an attempt to make it
53        more readable (this is probably subjective)
54      - call seaice_itd_redist once in the initialisation phase to have the initial
55        conditions in the correct category
56      - finally: add new ridging routine for ITD code
57    
58    checkpoint64v (2014/04/11)
59  o pkg/ecco:  o pkg/ecco:
60    - add runtime parameters mdt[start,end]date[1,2]    - add runtime parameters mdt[start,end]date[1,2]
61    - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"    - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
62  o pkg/seaice:  o pkg/seaice:
63    - make deltaC a global variable, so that it can be used in ridging code    - make deltaC a global variable, so that it can be used in ridging code
64    - first step towards ridging: introduce new routines that compute    - first step towards ridging: introduce new routines that compute
65      ice strength based on ridging parameters      ice strength based on ridging parameters
66      - add diagnostic for HSNOWITD
67      - add opnWtrFrac as a global variable (required for ridging scheme)
68  o pkg/salt_plume + pkg/seaice/seaice_growth.F  o pkg/salt_plume + pkg/seaice/seaice_growth.F
69    - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice    - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
70      AREA exceeds a threshold (code contributed by I.Fenty in 2011)      AREA exceeds a threshold (code contributed by I.Fenty in 2011)
