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)
71     - save 1 rho computation.
72     - no longer modify T & S inland when using down_slope pkg.
73    o gad_som : allow to switch to SOM advection for T & S without corresponding
74      pickup files (using new S/R: MDS_CHECK4FILE).
75    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
76      (for useSingleCpuIO to work in multi-threaded)
77    o pkg/shelfice:
78     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
79       with SHELFICEtopoFile in data.shelfice
80     - move code for reading ice shelf topography and modifying hFacC into separate
81       subroutines of the shelfice package
82     - separate initialisation of "fixed" and "variable" variables
83     - kTopC is not (yet) replaced by kSurfC, although this is possible
84    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
85    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
86      and rename:
87      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
88      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
89    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
90    
91    checkpoint61c
92    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
93      to add mass source/sink of fluid in the interior (3-D generalisation
94      of oceanic real-fresh water flux).
95    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
96    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
97    o new pkg: down_slope
98      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
99      - presently, modify T & S inland (dwnslp_calc_rho.F).
100        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
101      - implementation for ocean in P-coords not tested.
102      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
103    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
104      (to facilitate conversion of oceanic pkg to p-coordinate).
105    o change FIND_RHO to FIND_RHO_2D :
106      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
107    o new pkg: cheapaml
108    
109    checkpoint61b
110    o exch2:
111      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
112      - no longer depend on the order sequence (N,S,E,W).
113      - 3rd exchange no longer needed (tested with 24 tiles).
114      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
115      - exch_UV_A-grid readily available (but not yet tested).
116      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
117      (both are no longer needed) in exch_uv: no effect in forward run; but
118       get truncation error differences with adjoint exch.
119    o exch2:
120     - change index-bounds storage (moved from target to local tile,
121       more intuitive this way) ; rename/remove some variables.
122     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
123    
124    checkpoint61a
125    o exch2/matlab-topology-generator:
126      fix bug in index bounds for N-S internal exchange (hard to tell if this
127      had any effect on the solution).
128    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
129      is exceeded
130    o testreport: modify syntax of awk, so that it works also with
131      awk, and not only with nawk and gawk
132    
133    checkpoint61
134    o autodiff
135      Change default for TAF usage by removing argument '-nonew_arg'
136      This changes TAF subroutine argument list (ordering of active var.)
137      Omission of this flag leads to incompatibility w.r.t. TAMC
138      To restore TAMC-compatibility, need following modifs:
139      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
140      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
141      Tested TAF version is 1.9.22
142      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
143    
144    checkpoint60
145    --->>> This is the last checkpoint for which generating the adjoint
146    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
147    --->>> by default.
148    --->>> Future checkpoints will ommit this flag by default.
149    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
150    o pkg/grdchk: Add gradient check to etan0 perturbations.
151    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
152    o pkg/autodiff: more flexibility in zeroadj.
153      model/src: modifying do_oceanic_phys.F accordingly.
154    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
155    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
156      special setup of gmredi for which the adjoint is stable
157      enough for parameter optimization.
158    o bridging the gap between eddy stress and GM.
159      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
160          along with a change in CPP option (now ALLOW_EDDYPSI).
161      -> when using GM w/ GM_AdvForm:
162          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
163          is applied either in the tracer Eq. or in momentum Eq.
164          depending on data.gmredi (intro. GM_InMomAsStress).
165      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
166      The key modifications are in model/src/taueddy_external_forcing.F
167      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
168    
169    checkpoint59r
170    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
171      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
172      fix option to read coriolis(@ cell-corner) from files with CS-grid.
173    o pkg/mnc: add some attributes to standard 1D-coordinate variables
174    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
175      mass points, when using mnc for output
176      - add runtime parameter (missing_value, missing_value_int) to override
177        default (which is the value of getcon('UNDEF'))
178    o pkg/mnc: prepare mnc for the actual use of missing values with the
179      diagnostics package: small fix in mnc_cw_readwrite.template and more
180      initialisation of never used fields
181      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
182      versions
183    o pkg/thsice/thsice_ini_vars.F added default initial values so that
184      thermodynamics sea ice solver does not blow up when some initial fields
185      are missing.
186    o move from external_forcing_surf.F to ini_forcing.F
187      the p-coord. hack consisting in using pLoad to set phi0surf ;
188      update output of tutorial_global_oce_in_p (affected @ truncation level).
189    o Freshen up a bit hs94.1x64x5, notably:
190      remove rotationPeriod and tRef=5*0. (adjoint only), and add
191      exactConserv=.TRUE.
192    o pkg/generic_advdiff:
193      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
194      applies to files where Temperature & Salinity 2nd Order moments are used.
195    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
196      this uses a dynamically allocated internal state data structure
197      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
198      and requires a fortran 90 compiler
199    
200    checkpoint59q
201    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
202       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
203    o Refresh tutorial_global_oce_biogeo, notably:
204      - change bathymetry (put back seamounts in ACC, use hFacs)
205      - change EOS (POLY3 --> JMD95Z)
206      - use Bryan-Lewis vertical diffusivity
207      - use multidimensional advection
208      - remove old virtual virtual in dic pkg, now done through ptracer pkg
209      - change a couple of parameters in dic pkg
210    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
211    o pkg/obcs: change default to OBCSfixTopo = .true.,
212      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
213      - replace "debugMode" with "debugLevel .GE. debLevB"
214    o implementation of TAF directives for gchem,cfc,dic
215    o remove "exp5" (replaced by tutorial_deep_convection).
216    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
217      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
218      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
219      --> changes results in exp4, seaice_obcs
220    o tutorial_deep_convection :
221      update the set-up and increase resolution and domain size ; start
222      from pseudo initial conditions = output at t=120mn in order to see
223      something happening when running testreport.
224    o pkg/seaice: add os7mp as an advection scheme
225                  add check for advection schemes
226                  add a flag for restoring T and S underneath sea ice
227    o pkg/my82: add netcdf-support and diagnostics
228    o thsice pkg:
229      - Now hsMax limits snow height by turning it into ice following
230        flooding scheme (and now conserving energy)
231      - Slight rewriting of the formula in thsice_calc_thick.F
232      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
233      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
234    
235    checkpoint59p
236    o gchem / dic / cfc :
237      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
238      - add new parameter files: "data.dic" & "data.cfc" ;
239      - various re-arrangement in initialisation & header file ;
240      - fix tutorial_global_oce_biogeo for multi-threaded test.
241    o pkg/dic: test for "pickup_dic" file when restarting ;
242      if no pickup-file, can restart with a re-initialised pH (same as it did
243      before) providing pickupStrictlyMatch is set to False.
244    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
245      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
246    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
247      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
248    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
249     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
250       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
251    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
252       scheme to use for vorticty-term ;
253     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
254       (with default selectVortScheme, return to original discretisation)
255     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
256    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
257    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
258      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
259      also fix diagnostics VISCAHW & VISCA4W.
260    
261    checkpoint59o
262    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
263    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
264      move a few statemens out the main loop into separate loops
265    o pkg/shelfice:
266      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
267        (kg/m^2/s), does not break tests, because in verification/isomip,
268        rhoConstFresh=rhoConst (by accident)
269      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
270      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
271        new file model/src/seawater.F, so that they are available for all pkgs.
272      - convert potential temperature into in-situ temperature. This changes the
273        isomip tests => update tests
274    o add a flag writePickupAtEnd (default=true) to be able to suppress
275      writing a pickup at the last timestep
276    o tools/mpack-1.6 :
277      - disable automake (not working) and autoconf (not needed).
278      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
279        also cleaner with much less compilation warnings.
280    o pkg/profiles:
281      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
282      (for "less than 32 characters name" compiler requirement)
283    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
284      conditions that have a different sampling frequency than S/T/U/V obcs
285    o pkg/diagnostics (stats-diags):
286      - fix global Min/Max in case 1 processor get only empty tiles
287  o genmake2: replace (4 times)  o genmake2: replace (4 times)
288       make genmake_tc_1.o >> genmake_warnings 2>&1       make genmake_tc_1.o >> genmake_warnings 2>&1
