5      ==============================      ==============================
6    
7    o verification/global_ocean.cs32x15:
8      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
9        with "selectNHfreeSurf=1".
10    o model/src (non-hydrostatic free-surface):
11      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
12        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
13      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
14        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
15        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
16        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
17      - Update output (changes at machine truncation level) of verification exp:
18        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
19        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
20    o pkg/seaice: ITD code
21      - fix picking up from a single category model by initialising
22        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
23      - split a long warning message in seaice_check_pickup.F into two lines,
24        because NEC SX-ACE cannot deal with the long line.
25    o model/src:
26      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
27    o pkg/seaice:
28      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
29    o pkg/seaice:
30      - add basal stress as parameterisation for grounding ice
31        following Lemieux et al. (2015)
32      - turn on by setting new parameter SEAICEbasalDragK2 to a value
33        larger than 0. Lemieux et al. (2015) recommend 15.
34      - The adjoint complains with extra recomputations so there is also a
35        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
36        order to postpone the problem
37      - compile the new code in lab_sea
38    o verification/halfpipe_streamice:
39      - update both TAF and OpenAD adm output (machine truncation differences)
40    
41    checkpoint65v (2016/04/08)
42    o verification/advect_xz:
43      - increase overlap size from 3 to 4 and add new secondary test for PQM
44        advection scheme (with mono & wino limiter).
45      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
46    o model/src:
47      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
48        added phi0Ref) to set vertical axis origin and phiRef origin;
49        keep Ro_SeaLevel for backward compatibility (with a warning).
50       According to coordinate and fluid type:
51        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
52        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
53        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
54        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
55      - remove Ro_SeaLevel from ATM experiment parameter files;
56      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
57        complement; update output.txt (changes at machine truncation level).
58    o pkg/seaice/seaice_evp.F
59      - simplify computation of deltaZ and zetaZ to simple averaging following
60        Bouillon et al. (2013). This removes a lot of code, but also changes
61        verification experiment lab_sea.hb87 -> updated
62    
63    checkpoint65u (2016/03/14)
64    o pkg/generic_advdiff:
65      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
66        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
67        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
68        testing and not for actual use.
69    o model/src:
70      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
71        origin r = rF(1);
72      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
73        in EOS for height coordinate: enable to include NH Pressure or to use
74        more accurate pressure vertical profile; options not linked to EOS type
75        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
76      - start to implement variable gravity (along vertical): for now, only with
77        z-coords (not even z*).
78      - add Ideal Gas equation of state for height coordinate.
79      - update OpenAD output (affected at machine truncation level) of exp:
80        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
81    o pkg/exf:
82      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
83        of exf interpolation (before any rescaling, rotation or interpolation
84        to velocity point) for each field that gets loaded from file. This option
85        identically mimics the input file organization (e.g. record numbers in year
86        by year input files) besides the change in horizontal grid.
87      - add rotateStressOnAgrid run-time switch so that wind stress fields
88        can be provided on the A-grid in zonal/meridional direction and
89        rotated on the fly. This only applies to the case when the exf
90        interpolation is off and rotateStressOnAgrid is false by default.
91    o model/src:
92      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
93        it's also used with pkg/atm_phys) and add few more parameters (but still
94        inactive, src code yet to come)
