4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/flt:
8     - improve criteria for finding which tile owns a float.
9     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
10    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
11      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
12      with ocean biogeo)
13    o pkg/flt:
14     - do some cleaning and fix the restart ;
15     - add output.txt in flt_example/results to get this pkg tested.
16    o genmake2: add an EXTENDED_SRC option and flag.
17       for now, cannot be turned on on command line (only through genmake_local)
18    o pkg/mdsio: read/write vector:
19     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
20     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
21       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
22     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
23      (drop to 4 digits matching for grad). But this test does not look very
24      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
25    
26    checkpoint61g
27    o pkg/flt:
28      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
29       + make OPTIONS file more standard.
30      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
31      - fix _BYTESWAPIO CPP-Flag
32      - standard reading of file-parameter "data.flt"
33      - fix argument list of S/R FLT_RESTART
34      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
35    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
36    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
37      a still unfixed compiler/optimization bug
38    
39    checkpoint61f
40    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
41      update results of global_ocean.cs32x15.icedyn test.
42    o move getcon.F from model/src to pkg/fizhi.
43    o pkg/exf: add parameter for extrapolation of temp up to the surface
44       and option to prevent negative evap (in bulk_largeyeager04 only).
45    o Prather Advection scheme: fix tracer conservation for divergent flow
46      (e.g., when using NonLin Free-Surface).
47    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
48    o gmredi (Visbeck-variable-K):
49     - add more parameters to Visbeck-variable-K.
50     - use a 5 points average for dSigmaR in Visbeck-K calculation
51       (more "homogenous": same stencil and same weights as in dSigmaH)
52     - update output of ideal_2D_oce experiment.
53    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
54      (#undef REAL4_IS_SLOW)
55     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
56       coordinate variable
57     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
58       (surface forcing fields), removes some of the functionality
59     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
60     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
61       probably not all: copy _RS surface flux fields to RL field before
62       calling DIAGNOSTICS_FILL
63     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
64       real*4 (CALL EXCH_*_RS) versions.
65     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
66       (generate new output).
67    
68    checkpoint61e
69    o gmredi (Visbeck-variable-K):
70      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
71      - change computation of Visbeck-K where Slope > Smax :        
72        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
73        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
74    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
75      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
76    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
77    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
78      does not become too large (to avoid precision problems in implicit-diffusion
79      solver); update ideal_2D_oce output.
80    o pkg ggl90:
81      - in ggl90_cal.F: compute only one set of visc/diff, used to
82        step forward TKE/T/S/momentum
83      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
84        have Prandlt =1)
85    o gmredi (fm07):
86      - add lower limit on Transition layer thickness + lower limit on 1/lambda
87      - allow to set few more params from data.gmredi
88    o pkg ggl90:
89          - add missing sqrt(2) factor in computation of mixing length
90            scale in ggl90_calc.F
91            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
92    
93    checkpoint61d
94    o adjoint modifs
95      - adapt to new field rhoInSitu
96      - allow to revert from StoreDynVars2D, StoreDynVars3D
97        to individual fields
98        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
99    o store 3-D (in-situ) density in commom block (DYNVARS.h)
100     - save 1 rho computation.
101     - no longer modify T & S inland when using down_slope pkg.
102    o gad_som : allow to switch to SOM advection for T & S without corresponding
103      pickup files (using new S/R: MDS_CHECK4FILE).
104    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
105      (for useSingleCpuIO to work in multi-threaded)
106    o pkg/shelfice:
107     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
108       with SHELFICEtopoFile in data.shelfice
109     - move code for reading ice shelf topography and modifying hFacC into separate
110       subroutines of the shelfice package
111     - separate initialisation of "fixed" and "variable" variables
112     - kTopC is not (yet) replaced by kSurfC, although this is possible
113    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
114    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
115      and rename:
116      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
117      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
118    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
119    
120    checkpoint61c
121    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
122      to add mass source/sink of fluid in the interior (3-D generalisation
123      of oceanic real-fresh water flux).
124    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
125  o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)  o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
126  o new pkg: down_slope  o new pkg: down_slope
127    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
