5      ==============================      ==============================
6    
7    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
8    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
9      special setup of gmredi for which the adjoint is stable
10      enough for parameter optimization.
11    o bridging the gap between eddy stress and GM.
12      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
13          along with a change in CPP option (now ALLOW_EDDYPSI).
14      -> when using GM w/ GM_AdvForm:
15          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
16          is applied either in the tracer Eq. or in momentum Eq.
17          depending on data.gmredi (intro. GM_InMomAsStress).
18      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
19      The key modifications are in model/src/taueddy_external_forcing.F
20      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
21    checkpoint59r
22    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
23      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
24      fix option to read coriolis(@ cell-corner) from files with CS-grid.
25    o pkg/mnc: add some attributes to standard 1D-coordinate variables
26    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
27      mass points, when using mnc for output
28      - add runtime parameter (missing_value, missing_value_int) to override
29        default (which is the value of getcon('UNDEF'))
30    o pkg/mnc: prepare mnc for the actual use of missing values with the
31      diagnostics package: small fix in mnc_cw_readwrite.template and more
32      initialisation of never used fields
33      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
34      versions
35    o pkg/thsice/thsice_ini_vars.F added default initial values so that
36      thermodynamics sea ice solver does not blow up when some initial fields
37      are missing.
38    o move from external_forcing_surf.F to ini_forcing.F
39      the p-coord. hack consisting in using pLoad to set phi0surf ;
40      update output of tutorial_global_oce_in_p (affected @ truncation level).
41    o Freshen up a bit hs94.1x64x5, notably:
42      remove rotationPeriod and tRef=5*0. (adjoint only), and add
43      exactConserv=.TRUE.
44    o pkg/generic_advdiff:
45      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
46      applies to files where Temperature & Salinity 2nd Order moments are used.
47    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
48      this uses a dynamically allocated internal state data structure
49      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
50      and requires a fortran 90 compiler
51    
52    checkpoint59q
53    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
54       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
55    o Refresh tutorial_global_oce_biogeo, notably:
56      - change bathymetry (put back seamounts in ACC, use hFacs)
57      - change EOS (POLY3 --> JMD95Z)
58      - use Bryan-Lewis vertical diffusivity
59      - use multidimensional advection
60      - remove old virtual virtual in dic pkg, now done through ptracer pkg
61      - change a couple of parameters in dic pkg
62    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
63    o pkg/obcs: change default to OBCSfixTopo = .true.,
64      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
65      - replace "debugMode" with "debugLevel .GE. debLevB"
66    o implementation of TAF directives for gchem,cfc,dic
67    o remove "exp5" (replaced by tutorial_deep_convection).
68    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
69      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
70      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
71      --> changes results in exp4, seaice_obcs
72    o tutorial_deep_convection :
73      update the set-up and increase resolution and domain size ; start
74      from pseudo initial conditions = output at t=120mn in order to see
75      something happening when running testreport.
76    o pkg/seaice: add os7mp as an advection scheme
77                  add check for advection schemes
78                  add a flag for restoring T and S underneath sea ice
79    o pkg/my82: add netcdf-support and diagnostics
80    o thsice pkg:
81      - Now hsMax limits snow height by turning it into ice following
82        flooding scheme (and now conserving energy)
83      - Slight rewriting of the formula in thsice_calc_thick.F
84      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
85      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
86    
87    checkpoint59p
88    o gchem / dic / cfc :
89      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
90      - add new parameter files: "data.dic" & "data.cfc" ;
91      - various re-arrangement in initialisation & header file ;
92      - fix tutorial_global_oce_biogeo for multi-threaded test.
93    o pkg/dic: test for "pickup_dic" file when restarting ;
94      if no pickup-file, can restart with a re-initialised pH (same as it did
95      before) providing pickupStrictlyMatch is set to False.
96    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
97      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
98    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
99      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
100    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
101     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
102       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
103    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
104       scheme to use for vorticty-term ;
105     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
106       (with default selectVortScheme, return to original discretisation)
107     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
108    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
109    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
110      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
111      also fix diagnostics VISCAHW & VISCA4W.
112    
113    checkpoint59o
114    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
115    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
116      move a few statemens out the main loop into separate loops
117  o pkg/shelfice:  o pkg/shelfice:
118    - sort out freshwater flux; convert freshwater fluxes to mass fluxes    - sort out freshwater flux; convert freshwater fluxes to mass fluxes

130      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
