4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/diagnostics with "periodic averaging diagnostics":
8      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
9    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
10    o pkg/obcs: fix loop ranges for balancing code
11    o pkg/flt:
12     - improve criteria for finding which tile owns a float.
13     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
14    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
15      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
16      with ocean biogeo)
17    o pkg/flt:
18     - do some cleaning and fix the restart ;
19     - add output.txt in flt_example/results to get this pkg tested.
20    o genmake2: add an EXTENDED_SRC option and flag.
21       for now, cannot be turned on on command line (only through genmake_local)
22    o pkg/mdsio: read/write vector:
23     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
24     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
25       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
26     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
27      (drop to 4 digits matching for grad). But this test does not look very
28      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
29    
30    checkpoint61g
31    o pkg/flt:
32      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
33       + make OPTIONS file more standard.
34      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
35      - fix _BYTESWAPIO CPP-Flag
36      - standard reading of file-parameter "data.flt"
37      - fix argument list of S/R FLT_RESTART
38      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
39    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
40    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
41      a still unfixed compiler/optimization bug
42    
43    checkpoint61f
44    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
45      update results of global_ocean.cs32x15.icedyn test.
46    o move getcon.F from model/src to pkg/fizhi.
47    o pkg/exf: add parameter for extrapolation of temp up to the surface
48       and option to prevent negative evap (in bulk_largeyeager04 only).
49    o Prather Advection scheme: fix tracer conservation for divergent flow
50      (e.g., when using NonLin Free-Surface).
51    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
52    o gmredi (Visbeck-variable-K):
53     - add more parameters to Visbeck-variable-K.
54     - use a 5 points average for dSigmaR in Visbeck-K calculation
55       (more "homogenous": same stencil and same weights as in dSigmaH)
56     - update output of ideal_2D_oce experiment.
57    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
58      (#undef REAL4_IS_SLOW)
59     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
60       coordinate variable
61     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
62       (surface forcing fields), removes some of the functionality
63     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
64     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
65       probably not all: copy _RS surface flux fields to RL field before
66       calling DIAGNOSTICS_FILL
67     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
68       real*4 (CALL EXCH_*_RS) versions.
69     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
70       (generate new output).
71    
72    checkpoint61e
73    o gmredi (Visbeck-variable-K):
74      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
75      - change computation of Visbeck-K where Slope > Smax :        
76        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
77        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
78    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
79      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
80    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
81    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
82      does not become too large (to avoid precision problems in implicit-diffusion
83      solver); update ideal_2D_oce output.
84    o pkg ggl90:
85      - in ggl90_cal.F: compute only one set of visc/diff, used to
86        step forward TKE/T/S/momentum
87      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
88        have Prandlt =1)
89    o gmredi (fm07):
90      - add lower limit on Transition layer thickness + lower limit on 1/lambda
91      - allow to set few more params from data.gmredi
92    o pkg ggl90:
93          - add missing sqrt(2) factor in computation of mixing length
94            scale in ggl90_calc.F
95            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
96    
97    checkpoint61d
98    o adjoint modifs
99      - adapt to new field rhoInSitu
100      - allow to revert from StoreDynVars2D, StoreDynVars3D
101        to individual fields
102        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
103    o store 3-D (in-situ) density in commom block (DYNVARS.h)
104     - save 1 rho computation.
105     - no longer modify T & S inland when using down_slope pkg.
106    o gad_som : allow to switch to SOM advection for T & S without corresponding
107      pickup files (using new S/R: MDS_CHECK4FILE).
108    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
109      (for useSingleCpuIO to work in multi-threaded)
110    o pkg/shelfice:
111     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
112       with SHELFICEtopoFile in data.shelfice
113     - move code for reading ice shelf topography and modifying hFacC into separate
114       subroutines of the shelfice package
115     - separate initialisation of "fixed" and "variable" variables
116     - kTopC is not (yet) replaced by kSurfC, although this is possible
117    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
118    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
119      and rename:
120      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
121      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
122    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
123    
124    checkpoint61c
125    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
126      to add mass source/sink of fluid in the interior (3-D generalisation
127      of oceanic real-fresh water flux).
128    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
129    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
130    o new pkg: down_slope
131      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
132      - presently, modify T & S inland (dwnslp_calc_rho.F).
133        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
134      - implementation for ocean in P-coords not tested.
135      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
136    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
137      (to facilitate conversion of oceanic pkg to p-coordinate).
138    o change FIND_RHO to FIND_RHO_2D :
139      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
140    o new pkg: cheapaml
141    
142    checkpoint61b
143    o exch2:
144      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
145      - no longer depend on the order sequence (N,S,E,W).
146      - 3rd exchange no longer needed (tested with 24 tiles).
147      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
148      - exch_UV_A-grid readily available (but not yet tested).
149      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
150      (both are no longer needed) in exch_uv: no effect in forward run; but
151       get truncation error differences with adjoint exch.
152    o exch2:
153     - change index-bounds storage (moved from target to local tile,
154       more intuitive this way) ; rename/remove some variables.
155     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
156    
157    checkpoint61a
158    o exch2/matlab-topology-generator:
159      fix bug in index bounds for N-S internal exchange (hard to tell if this
160      had any effect on the solution).
161    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
162      is exceeded
163    o testreport: modify syntax of awk, so that it works also with
164      awk, and not only with nawk and gawk
165    
166    checkpoint61
167  o autodiff  o autodiff
168    Change default for TAF usage by removing argument '-nonew_arg'    Change default for TAF usage by removing argument '-nonew_arg'
169    This changes TAF subroutine argument list (ordering of active var.)    This changes TAF subroutine argument list (ordering of active var.)
