4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
8      (#undef REAL4_IS_SLOW)
9     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
10       coordinate variable
11     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
12       (surface forcing fields), removes some of the functionality
13     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
14     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
15       probably not all: copy _RS surface flux fields to RL field before
16       calling DIAGNOSTICS_FILL
17    
18    checkpoint61e
19    o gmredi (Visbeck-variable-K):
20      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
21      - change computation of Visbeck-K where Slope > Smax :        
22        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
23        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
24    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
25      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
26    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
27    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
28      does not become too large (to avoid precision problems in implicit-diffusion
29      solver); update ideal_2D_oce output.
30    o pkg ggl90:
31      - in ggl90_cal.F: compute only one set of visc/diff, used to
32        step forward TKE/T/S/momentum
33      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
34        have Prandlt =1)
35    o gmredi (fm07):
36      - add lower limit on Transition layer thickness + lower limit on 1/lambda
37      - allow to set few more params from data.gmredi
38    o pkg ggl90:
39          - add missing sqrt(2) factor in computation of mixing length
40            scale in ggl90_calc.F
41            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
42    
43    checkpoint61d
44    o adjoint modifs
45      - adapt to new field rhoInSitu
46      - allow to revert from StoreDynVars2D, StoreDynVars3D
47        to individual fields
48        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
49    o store 3-D (in-situ) density in commom block (DYNVARS.h)
50     - save 1 rho computation.
51     - no longer modify T & S inland when using down_slope pkg.
52    o gad_som : allow to switch to SOM advection for T & S without corresponding
53      pickup files (using new S/R: MDS_CHECK4FILE).
54    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
55      (for useSingleCpuIO to work in multi-threaded)
56    o pkg/shelfice:
57     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
58       with SHELFICEtopoFile in data.shelfice
59     - move code for reading ice shelf topography and modifying hFacC into separate
60       subroutines of the shelfice package
61     - separate initialisation of "fixed" and "variable" variables
62     - kTopC is not (yet) replaced by kSurfC, although this is possible
63    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
64    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
65      and rename:
66      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
67      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
68    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
69    
70    checkpoint61c
71    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
72      to add mass source/sink of fluid in the interior (3-D generalisation
73      of oceanic real-fresh water flux).
74    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
75    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
76    o new pkg: down_slope
77      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
78      - presently, modify T & S inland (dwnslp_calc_rho.F).
79        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
80      - implementation for ocean in P-coords not tested.
81      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
82    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
83      (to facilitate conversion of oceanic pkg to p-coordinate).
84    o change FIND_RHO to FIND_RHO_2D :
85      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
86    o new pkg: cheapaml
87    
88    checkpoint61b
89    o exch2:
90      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
91      - no longer depend on the order sequence (N,S,E,W).
92      - 3rd exchange no longer needed (tested with 24 tiles).
93      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
94      - exch_UV_A-grid readily available (but not yet tested).
95      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
96      (both are no longer needed) in exch_uv: no effect in forward run; but
97       get truncation error differences with adjoint exch.
98    o exch2:
99     - change index-bounds storage (moved from target to local tile,
100       more intuitive this way) ; rename/remove some variables.
101     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
102    
103    checkpoint61a
104    o exch2/matlab-topology-generator:
105      fix bug in index bounds for N-S internal exchange (hard to tell if this
106      had any effect on the solution).
107    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
108      is exceeded
109    o testreport: modify syntax of awk, so that it works also with
110      awk, and not only with nawk and gawk
111    
112    checkpoint61
113    o autodiff
114      Change default for TAF usage by removing argument '-nonew_arg'
115      This changes TAF subroutine argument list (ordering of active var.)
116      Omission of this flag leads to incompatibility w.r.t. TAMC
117      To restore TAMC-compatibility, need following modifs:
118      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
119      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
120      Tested TAF version is 1.9.22
121      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
122    
123    checkpoint60
124    --->>> This is the last checkpoint for which generating the adjoint
125    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
126    --->>> by default.
127    --->>> Future checkpoints will ommit this flag by default.
128    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
129    o pkg/grdchk: Add gradient check to etan0 perturbations.
130    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
131  o pkg/autodiff: more flexibility in zeroadj.  o pkg/autodiff: more flexibility in zeroadj.
