5      ==============================      ==============================
6    
7    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
8      this uses a dynamically allocated internal state data structure
9      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
10      and requires a fortran 90 compiler
11    
12    checkpoint59q
13    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
14       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
15    o Refresh tutorial_global_oce_biogeo, notably:
16      - change bathymetry (put back seamounts in ACC, use hFacs)
17      - change EOS (POLY3 --> JMD95Z)
18      - use Bryan-Lewis vertical diffusivity
19      - use multidimensional advection
20      - remove old virtual virtual in dic pkg, now done through ptracer pkg
21      - change a couple of parameters in dic pkg
22    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
23    o pkg/obcs: change default to OBCSfixTopo = .true.,
24      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
25      - replace "debugMode" with "debugLevel .GE. debLevB"
26    o implementation of TAF directives for gchem,cfc,dic
27    o remove "exp5" (replaced by tutorial_deep_convection).
28    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
29      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
30      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
31      --> changes results in exp4, seaice_obcs
32    o tutorial_deep_convection :
33      update the set-up and increase resolution and domain size ; start
34      from pseudo initial conditions = output at t=120mn in order to see
35      something happening when running testreport.
36    o pkg/seaice: add os7mp as an advection scheme
37                  add check for advection schemes
38                  add a flag for restoring T and S underneath sea ice
39    o pkg/my82: add netcdf-support and diagnostics
40    o thsice pkg:
41      - Now hsMax limits snow height by turning it into ice following
42        flooding scheme (and now conserving energy)
43      - Slight rewriting of the formula in thsice_calc_thick.F
44      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
45      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
46    
47    checkpoint59p
48    o gchem / dic / cfc :
49      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
50      - add new parameter files: "data.dic" & "data.cfc" ;
51      - various re-arrangement in initialisation & header file ;
52      - fix tutorial_global_oce_biogeo for multi-threaded test.
53    o pkg/dic: test for "pickup_dic" file when restarting ;
54      if no pickup-file, can restart with a re-initialised pH (same as it did
55      before) providing pickupStrictlyMatch is set to False.
56    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
57      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
58    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
59      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
60    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
61     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
62       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
63    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
64       scheme to use for vorticty-term ;
65     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
66       (with default selectVortScheme, return to original discretisation)
67     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
68    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
69    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
70      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
71      also fix diagnostics VISCAHW & VISCA4W.
72    
73    checkpoint59o
74    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
75    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
76      move a few statemens out the main loop into separate loops
77    o pkg/shelfice:
78      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
79        (kg/m^2/s), does not break tests, because in verification/isomip,
80        rhoConstFresh=rhoConst (by accident)
81      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
82      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
83        new file model/src/seawater.F, so that they are available for all pkgs.
84      - convert potential temperature into in-situ temperature. This changes the
85        isomip tests => update tests
86    o add a flag writePickupAtEnd (default=true) to be able to suppress
87      writing a pickup at the last timestep
88    o tools/mpack-1.6 :
89      - disable automake (not working) and autoconf (not needed).
90      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
91        also cleaner with much less compilation warnings.
92    o pkg/profiles:
93      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
94      (for "less than 32 characters name" compiler requirement)
95    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
96      conditions that have a different sampling frequency than S/T/U/V obcs
97    o pkg/diagnostics (stats-diags):
98      - fix global Min/Max in case 1 processor get only empty tiles
99    o genmake2: replace (4 times)
100         make genmake_tc_1.o >> genmake_warnings 2>&1
101      with
102         COMM="$CC $CFLAGS -c genmake_tc_1.c"
103         echo $COMM >> genmake_warnings
104         $COMM >> genmake_warnings 2>&1
105      to make genmake2 always see the value of CC as specified in the optfile.
106    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
107      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
108      - modify verification advect_cs test to test SOM-advection on CS-grid.
109    o pkg/ctrl:
110      - Rewrite of ctrl_map_ini_ecco.F,
111        introducing a generic routine (ctrl_map_ini_gen.F).
112      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
113    
114    checkpoint59n
115    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
116      number in dedicate array "hdiag":
117      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
118        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
119      - many small changes (integer format) for large number of diagnostics
120      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
121        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
122    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
123      usingSphericalGrid, this allows to define the rotated grid coordinates
124      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
125      geographical coordinates according to the inverse of the rotation defined
126      by the Euler angles, so that Coriolis parameter and online-interpolation by
127      exf works with the geographical coordinates on XC/YC/XG/YG.
128      Naturally, this feature does not work with all packages, so some
129      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
130      profiles), because there the coordinates are assumed to be regular
131      spherical grid coordinates.
132    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
133      - introduce isopycnal diffusion coefficient control.
134    o tools/adjoint_options:
135      - additional control vector components.
136    o pkg/mnc: have mnc create marginally meaning full coordinate variables
137      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
138  o pkg/mypackage:  o pkg/mypackage:
139    - add example of read/write pickup for state-var ;    - add example of read/write pickup for state-var ;
140    - add entry points to the main code for state-vars diags & write-pickup.    - add entry points to the main code for state-vars diags & write-pickup.
