4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/flt:
8     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
9       init_fixed & ini_varia.
10    o pkg/ggl90: a few modifications:
11     - fix bottom boundary condition, and interpolation of KappaE
12       near top and bottom
13     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
14     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
15     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
16    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
17      (maintain temporary backward compatibility, until next checkpoint)
18    
19    checkpoint61h
20    o pkg/diagnostics with "periodic averaging diagnostics":
21      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
22    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
23    o pkg/obcs: fix loop ranges for balancing code
24    o pkg/flt:
25     - improve criteria for finding which tile owns a float.
26     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
27    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
28      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
29      with ocean biogeo)
30    o pkg/flt:
31     - do some cleaning and fix the restart ;
32     - add output.txt in flt_example/results to get this pkg tested.
33    o genmake2: add an EXTENDED_SRC option and flag.
34       for now, cannot be turned on on command line (only through genmake_local)
35    o pkg/mdsio: read/write vector:
36     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
37     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
38       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
39     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
40      (drop to 4 digits matching for grad). But this test does not look very
41      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
42    
43    checkpoint61g
44    o pkg/flt:
45      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
46       + make OPTIONS file more standard.
47      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
48      - fix _BYTESWAPIO CPP-Flag
49      - standard reading of file-parameter "data.flt"
50      - fix argument list of S/R FLT_RESTART
51      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
52    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
53    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
54      a still unfixed compiler/optimization bug
55    
56    checkpoint61f
57    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
58      update results of global_ocean.cs32x15.icedyn test.
59    o move getcon.F from model/src to pkg/fizhi.
60    o pkg/exf: add parameter for extrapolation of temp up to the surface
61       and option to prevent negative evap (in bulk_largeyeager04 only).
62    o Prather Advection scheme: fix tracer conservation for divergent flow
63      (e.g., when using NonLin Free-Surface).
64    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
65    o gmredi (Visbeck-variable-K):
66     - add more parameters to Visbeck-variable-K.
67     - use a 5 points average for dSigmaR in Visbeck-K calculation
68       (more "homogenous": same stencil and same weights as in dSigmaH)
69     - update output of ideal_2D_oce experiment.
70    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
71      (#undef REAL4_IS_SLOW)
72     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
73       coordinate variable
74     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
75       (surface forcing fields), removes some of the functionality
76     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
77     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
78       probably not all: copy _RS surface flux fields to RL field before
79       calling DIAGNOSTICS_FILL
80     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
81       real*4 (CALL EXCH_*_RS) versions.
82     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
83       (generate new output).
84    
85    checkpoint61e
86    o gmredi (Visbeck-variable-K):
87      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
88      - change computation of Visbeck-K where Slope > Smax :        
89        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
90        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
91    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
92      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
93    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
94    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
95      does not become too large (to avoid precision problems in implicit-diffusion
96      solver); update ideal_2D_oce output.
97  o pkg ggl90:  o pkg ggl90:
98    - in ggl90_cal.F: compute only one set of visc/diff, used to    - in ggl90_cal.F: compute only one set of visc/diff, used to
99      step forward TKE/T/S/momentum      step forward TKE/T/S/momentum
100    - default value of GGL90viscMax/GGL90diffMax larger and equal (to    - default value of GGL90viscMax/GGL90diffMax larger and equal (to
101      have Prandlt =1)      have Prandlt =1)
102  o gmredi(fm07):  o gmredi (fm07):
103    - add lower limit on Transition layer thickness D + lower limit on D/lambda    - add lower limit on Transition layer thickness + lower limit on 1/lambda
104    - allow to set few more params from data.gmredi    - allow to set few more params from data.gmredi
105  o pkg ggl90:  o pkg ggl90:
106        - add missing sqrt(2) factor in computation of mixing length        - add missing sqrt(2) factor in computation of mixing length
