5      ==============================      ==============================
6    
7    o vectorize salt_plume package:
8      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
9      - this code computes plumebk everywhere (also over land), thus requires
10        code to avoid divisions by zero and catch the case of kLev=Nr.
11      - efficiency of salt_plume_frac is still sub-optimal
12    o tools (genmake2):
13      - fix makefile NAME specification (option: -makefile NAME) by adding
14        "-f $MAKEFILE" in few places where it was missing including makedepend
15        command (contribution from Paul).
16    
17    checkpoint63i (2012/01/24)
18    o model/src:
19      - add factorized versions of some EOS code to find_rho.F,
20        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
21    o model/src:
22      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
23      - change default celsius2K from 273.16 to 273.15
24      - to keep results unchanged, add back old value of celsius2K in verification
25        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
26         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
27    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
28      to make TAF generate vectorizable code
29    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
30       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
31       have flags that do this more efficiently.
32    o pkg/diagnostics/diagstats_calc.F
33      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
34    o pkg/obcs (with exch2):
35      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
36        and remove code (in obcs_readparms.F) which was based on EXCH of indices
37        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
38    o pkg/exf and seaice exp:
39      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
40        so that switching off area & heff advection flags does not affect results.
41      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
42      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
43        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
44        results of verification experiments: 1D_ocean_ice_column(fwd),
45        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
46        and offline_exf_seaice (all 4).
47    o pkg/seaice:
48      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
49        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
50      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
51        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
52        not multi-dim advection;
53      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
54        SHORTWAVE_HEATING #undef.
55    o optim: make Makefile more robust (?)
56    o pkg/obcs:
57      * fix treatment of obcs_read_pickup for TAF
58    o pkg/shelfice:
59      * add missing initialisation of num_shifwflx
60      * new adjoint verification exp. for isomip
61      * change Prandtl and Schmidt numbers from generic formulations
62        (in terms of model diffus. and visc.) to separate runtime
63        parameters, with Holland and Jenkins (1999) default values.
64    o pkg/exf (interpolation):
65      - extended input field (2 rows) near the N & S poles:
66        * fill in with the symetric value (when even Nb of data in longitude)
67        * add average value at the poles only for scalar quantities ; for vector
68          component interpolation, skip the averaging and keep duplicated values,
69          unless the 2 components have same location (uvInterp=T) in which case
70          interpolate the 2 components together using S/R EXF_INTERP_UV.
71      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
72        together: this allows to account properly for local orientation when
73        averaging at N & S pole.
74      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
75        exf-interpolation near N & S poles. Undef by default.
76      - add debug check/print on 1rst iter if debugLevel >=2.
77    o pkg/exf:
78      - change masking flags definition (no longer "parameter"), put them in
79        common block and set them in S/R EXF_INIT_FIXED.
80      - change recognized masking flag from s,u,v to c,w,s since the mask
81        to use (maskC,W,S) depends on position on model grid and has little to
82        do with scalar/vector difference; fix masking if using P-coordinates.
83      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
84        and update results of exp. global_with_exf (x2).
85      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
86    o pkg/obcs
87      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
88    o pkg/exf (interpolation):
89      - assume periodicity in X only if input field cover full longitude range.
90      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
91        and should vectorise).
92      - fix input lat of the 2 added row (in case we provide N.pole data).
93    
94  checkpoint63h (2011/12/30)  checkpoint63h (2011/12/30)
95    o pkg/seaice:
96      - change declaration of UVM from _RL to _RS in order to get B-grid
97        uIce,vIce monitor when _RS = real*4
98  o pkg/offline:  o pkg/offline:
99    - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);    - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
100    - compute vertical velocity if not read from file (switch on exactConserv    - compute vertical velocity if not read from file (switch on exactConserv
