4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
8      a still unfixed compiler/optimization bug
9    
10    checkpoint61f
11    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
12      update results of global_ocean.cs32x15.icedyn test.
13    o move getcon.F from model/src to pkg/fizhi.
14    o pkg/exf: add parameter for extrapolation of temp up to the surface
15       and option to prevent negative evap (in bulk_largeyeager04 only).
16    o Prather Advection scheme: fix tracer conservation for divergent flow
17      (e.g., when using NonLin Free-Surface).
18    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
19    o gmredi (Visbeck-variable-K):
20     - add more parameters to Visbeck-variable-K.
21     - use a 5 points average for dSigmaR in Visbeck-K calculation
22       (more "homogenous": same stencil and same weights as in dSigmaH)
23     - update output of ideal_2D_oce experiment.
24    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
25      (#undef REAL4_IS_SLOW)
26     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
27       coordinate variable
28     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
29       (surface forcing fields), removes some of the functionality
30     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
31     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
32       probably not all: copy _RS surface flux fields to RL field before
33       calling DIAGNOSTICS_FILL
34     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
35       real*4 (CALL EXCH_*_RS) versions.
36     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
37       (generate new output).
38    
39    checkpoint61e
40    o gmredi (Visbeck-variable-K):
41      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
42      - change computation of Visbeck-K where Slope > Smax :        
43        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
44        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
45    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
46      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
47    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
48    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
49      does not become too large (to avoid precision problems in implicit-diffusion
50      solver); update ideal_2D_oce output.
51    o pkg ggl90:
52      - in ggl90_cal.F: compute only one set of visc/diff, used to
53        step forward TKE/T/S/momentum
54      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
55        have Prandlt =1)
56    o gmredi (fm07):
57      - add lower limit on Transition layer thickness + lower limit on 1/lambda
58      - allow to set few more params from data.gmredi
59    o pkg ggl90:
60          - add missing sqrt(2) factor in computation of mixing length
61            scale in ggl90_calc.F
62            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
63    
64    checkpoint61d
65    o adjoint modifs
66      - adapt to new field rhoInSitu
67      - allow to revert from StoreDynVars2D, StoreDynVars3D
68        to individual fields
69        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
70  o store 3-D (in-situ) density in commom block (DYNVARS.h)  o store 3-D (in-situ) density in commom block (DYNVARS.h)
71   - save 1 rho computation.   - save 1 rho computation.
72   - no longer modify T & S inland when using down_slope pkg.   - no longer modify T & S inland when using down_slope pkg.
