5      ==============================      ==============================
6    
7    o external_fields_load:
8      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
9       interpolation weights) to use in a periodic time-series ; do not divide by
10       time-step to convert to integer:
11       - this fixes case where externForcingPeriod is not multiple of time-step
12          (Thanks to Christopher L. Wolfe)
13       - this fixes case where externForcingPeriod is an odd multiple of time-step
14         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
15      store index of time-record which is currently loaded:
16       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
17       - needed for the adjoint but not yet used because of extensive recomputations;
18         (to be fixed soon)
19    
20    checkpoint62v (2011/04/02)
21    o verification/1D_ocean_ice_column added to test Ian Fenty's
22      pkg/seaice_growth.F modifications for improving sea ice code differentiability
23    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
24      (new velocity statistics after changing maskInW & maskInS definition)
25    o pkg/generic_advdiff with OBCS:
26      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
27      equivalent to assumption of no tracer gradient outside the OB region.
28      This will affect the results if using obcs+biharmonic diffusion.
29      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
30    o pkg/obcs:
31      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
32      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
33      in Interior region. No impact on solution but affects Velocity monitor stats.
34    o pkg/ptracers (adjoint)
35      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
36      tape file for each tracer
37    o model/inc/src and pkg/autodiff: add parameters that allow to turn
38      of parts of the adjoint code at run time. For now, there are only
39      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
40      parameters are set in data.pkg.
41      This is the lazy coward's version of doing this, but still useful for
42      debugging. In order to do it right, everything needs to be moved to
43      pkg/autodiff.
44    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
45      the end; this fixes the adjoint balancing code for open boundaries.
46    o pkg/ctrl:
47      - change behavior of xx_${varname}period to be analogous to exf-conventions:
48        xx_${varname}period =   0.,  means time-independent control part
49        xx_${varname}period = -12., means one-year-periodic monthly control part
50      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
51        clean up ctrl_init a little, remove unused variables
52      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
53      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
54    
55    checkpoint62u (2011/03/15)
56    o model/src:
57      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
58        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
59      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
60        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
61    o pkg/ctrl/obcs/ecco:
62      - remove obsolete, unused, and partially broken code:
63        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
64        ALLOW_CTRL_OBCS_BALANCE
65      - put a stop statement into ecco/cost_obcsvol.F, but also add
66        cost_obcsvol to ecco_ad_diff.list
67    o pkg/ecco: fix counting cost function contributions for obcs (code
68      by Matt M.) and diffkr for diagnostics
69    o pkg/ecco, pkg/ctrl, pkg/grdchk:
70      add cost penalty terms for initial uvel, vvel, eta controls
71      and I/O for prior error files
72    o pkg/mdsio:
73       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
74       (new argument) to check for tiled file in mdsioLocalDir : this fix the
75       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
76    o pkg/ctrl:
77     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
78       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
79       unused and superfluous variables
80     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
81    o pkg/ecco
82     - enable adjoint of Stevens OB
83    o pkg/ctrl/ecco/grdchk:
84      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
85        Fortunately, we do not have any tests for the numerous cpp-flagged
86        option of "obcs as control parameters" so we will never know
87        if this is an improvement (but at least now things compile).
88      - remove an obsolete initialization from ecco_cost_init_barfiles.F
89      - fix some problems within never used ifdefs to make the code compile
90    o pkg/obcs:
91     - Refine Interior mask definition to work with more complex OB (e.g.
92       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
93       read in Interior mask from file. Check if Interior mask is consistent
94       with OB list of indices.
95    o pkg/seaice
96     - beginning code for a seaice tracer package,
97       but currently only used for seaice age: SEAICE_AGE
98       SEAICE_num = 4
99       iTracer = 1: area-weighted ice age
100               = 2: volume-weighted ice age
101               = 3, 4: template for one-year vs. multi-year ice
102       data.seaice has new namelist SEAICE_PARM03 for arrays related to
103       SEAICE_num

105    checkpoint62t (2011/03/05)
106  o pkg/obcs:  o pkg/obcs:
107   - obcs_apply_uv.F: change to a 2 steps method, first tangential component;   - obcs_apply_uv.F: change to a 2 steps method, first tangential component;

130    o adjoint:
131     - enable adjoint of Stevens OB
132     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
133       (a bit delicate because of potentially modified adj. common block structure;
134       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
